Third week under second Covid-19 lock-down in Austria (6th Dec. 2020)

7. December 2020 Leave a comment

Three weeks of hard lock-down have passed and we are about to switch back to lock-down “light”. Stores will re-open on Monday 7th, but hotels, restaurants, bars and ski lifts remain closed. The curfew will be reduced from all-day to 18:00 – 06:00. Home-office has never been mandatory but recommended and will be recommended in the future.

Data shows that both lock-down “light” and “hard” lock-down were successful and infection rate is going down to high but stable niveau. Question is how will Christmas and New Year impact? We are eagerly watching the data from US and how Thanksgiving impacted the number of infections.

Infections are dropping after 3 weeks of hard lock-down
https://covid19-dashboard.ages.at/

Austria is staring voluntary free mass-testing. The army is organizing hundreds of testing sites all over the country. Anti-Gen quick tests are used to identify infectious people. These test have a very low false-negative rate. In case someone is identified as positive, a PCR test is done. Hopefully many non-symptomatic infections people can be found and isolated before Christmas to avoid a third wave and a third lock-down in January. While the registration was a digital disaster the testing itself was easy. Make an appointment and fill out a form. Bring the form and an ID card to the test site. If you have no printer at home it will be printed for you. Get tested and leave the test site. The result is sent to your mobile phone after aprox. 15 minutes.

It’s all over now, baby blue

No more Microsoft-Hosted Tier1 Dynamics 365 Finance / SCM environments

Microsoft-Hosted Dynamics 365 Finance and Supply Chain Management Tier1 environments are gone. If you need a development or build environment you have to host it at your own costs in an Azure subscription. Typically partners will create an Azure Subscription for the customer and deploy the Tier1 environments there. Depending on the size (recommended ist D12v2) and Auto-Shutdown strategy the costs will be somewhat equal to the former Tier1 Addons.

During the first lock-down in spring Azure reached its capacity limit in Europe. Even Netflix and YouTube reduced the streaming quality to HD and lower. Microsoft shut of Teams functionality like seaing someone typing in the chat window and video conferences. In spring we were advised to deploy Tier2 environments in other regions than Europe. Thankfully this time we did not experience such capacity limits although many partners deployed many virtual machines for their customers in November.

IT-Disaster Austria Part 1 – The empty Online Shop

This week was an IT disgrace for the Austrian government. Last week was Black-Friday week and Cyber Monday at Amazon. In order to strengthen Austrian companies the Ministry for Digital and Economic affairs together with the Austria Commerce Chamber decided invest 700.000€ to develop and launch an Austrian Online Shop. This week the “Kaufhaus Österreich” / “Store Austria” was launched and failed immediately. Because it is nothing more than a link list with a not functional search. The search does not index the products from the vendors but only their company name and description. For Example, if you search for a mouse no results are returned because no registered vendor has “mouse” in their company name 🤣

Kaufhaus Österreich — No mouse in Austria

IT-Disaster Austria Part 2 – COVID-19 mass-test registration

Austria will conduct free corona mass tests in December. To organize these tests an online registration page. There you have to provide name, social security number, Email or phone number. After the registration a mail is sent with a link to make an appointment in a local test center. The registration site was announced in the media but the registration site failed permanently with an unexpected error. People report that 5 or more try were required to get registered.

österreich-testet Corona Anmeldung — Registration site for Corona mass-test failed

But the “unexpected server error” on submit was not the only problem. The Austrian news paper Der Standard reported a list of problems:

The site went offline only few hours after launch because of an DDOS attack
People could not book an appointment in their home district
Someone managed to book so many appointments that a test site was exclusively blocked
Some Email addresses were deleted
The website had no imprint

Much more problematic is a huge data leak. More and more people report that they get personal data from other people. For example, on Wednesday a teacher from Carinthia reported that he got an appointment for another person from Vienna.

Second week under second Covid-19 lock-down in Austria (29th. Nov)

30. November 2020 Leave a comment

Home-Office and Remote-Work

The first lock-down in spring was a game changer. Home office has become normal. But also in non-lock-down times the usage of Microsoft Teams now is on a high volume. For us it has become the collaboration backbone.

Teams usage is stable no matter if lock-down

Webcast Marathon

Last week on 26th November we held a webcast marathon. We presented 6 talks for Dynamics 365 Finance and Power Platform. The webcasts were organized using Microsoft Teams Live Events. The registration pages were quickly built using Microsoft Forms and automated using Power Automate. When a new participant registered for a webcast, PA read the registration from Form, picked the corresponding .ics calendar, sent a mail to the participant with the calendar .ics as attachment and created a new record in Azure table storage.

It turned out that the combination of Office 365, Power Platform and Teams work great together and allows to manage a complex distributed scenario like a webcast with different speakers exclusivly in the cloud.

Lock-down results

In contrast to the very strict first lock-down in spring, the actual “hard” lock-down allows more exceptions.

Monday morning: Some stay at home but many (have to) go to work (30th November)

Monday morning : First week of first lock-down in spring (16th March)

In theory we have a curfew all day. Schools and Universities are closed, many retail stores are closed, home depots are closed for B2C customers and gastronomy is limited to delivery. But since going to work, sport and shopping is allowed we don’t really feel the pressure like in spring. However, it seems to work and the numbers are dropping.

New infections per day are dropping

Azure Backup Server agent installation trouble

19. November 2020 Leave a comment

Taking backups is crucial. I prefer to use the Azure cloud for storing backups. In case a disaster strikes on-premises, the data is at least save in the cloud. Microsoft is offering a great solution with Azure Backup. For taking simple file-based backups you only need the recovery agent installed on the source server. For taking more complex backups e.g. from SQL Server and HyperV the Azure Backup Server is required.

Azure Backup Server (aka. DPM)

The Azure Backup Server is a re-branded System Center Data Protection Manager. Backups can be stored locally on disk and in an Azure Backup Vault. Like the SCDPM Server, the Azure Backup Server requires agents to be installed on the source systems. This can be done using push or pull techniques. Within a domain you can instruct the DPM Server to install an agent on a server. You may also install the agent by hand and instruct DPM to connect to an already installed agent.

I had one legacy server hosting a SQL Server 2012 instance, which was protected with System Center Data Protection Manager 2012 a while ago. The old agents were uninstalled years ago but left some entries that blocked the installation of the new DPM agent.

Identifying the problem

When the installation fails, a Log is created in C:\Windows\Temp. A look in the log file revealed that the installer found an installed product that should not be installed.

Agent installation started
 The agent bootstrapper is doing prerequisite checks
 Querying for Product with Upgrade code: {0BEE7F6A-CE2A-A5CF-FFEB-8E0F8A8CDE75}

 Failed: Hr: = [0x80990a2d] : Encountered Failure: : lVal : InstallProtectionAgent(false , false )

To identify the problem get_wmiobject can be used to display ID and Name. A old version of System Center Data Protection Manager Agent was not removed properly.

get-wmiobject Win32_Product | Format-Table IdentifyingNumber, Name, LocalPackage -AutoSize

Remove DPM agent leftovers

A first attempt to get rid of the DPM 2012 was to clean the registry. Therefore the regedit.msc was called and all entries referencing {EFF053DE-592F-5574-9AA3-64662A944952} were deleted. This was not sufficient to install the new agent.

Microsoft provides a tool to remove entries from uninstalled programs. The tool MicrosoftProgram_Install_and_Uninstall.meta.diagcab can be downloaded here: Fix problems that block programs from being installed or removed . It found the entry for DPM 2012 and removed it.

Fixit for blocking installation / uninstallation

The tool was a great step in the right direction, however the installation failed again because the DPM service could not be installed. The log file showed the following entry:

Received type [0x01000000] message [Service 'DPM CPWrapper Service' (DpmCPWrapperService) could not be installed. Verify that you have sufficient privileges to install system services.]

It turned out that there was already a CPWrapper Service but it was not functional anymore. The path to binary was no longer working. Therefore the property dialog from the service MMC was also not working. But there exists a tool to remove corrupt service entries. Process Hacker can be used to simple delete the service entry.

Finally, the agent installation was successful

Azure Backup Server agent installation finished

Microsoft-hosted Dynamics 365 Finance Tier1 Sandboxes are dicontinued: Switch to Cloud-Hosted

12. October 2020 Leave a comment

Dynamics 365 Finance / SCM Tier1 sandbox environments are heavily used by partners for development and building Dynamics 365 Finance / SCM applications. Microsoft-hosted Tier 1 environments were a great deal because we got well sized VMs with 28 GB RAM and 4 Cores plus SQL Server, Visual Studio and Dynamics 365 Finance pre-installed for a very small fixed price per month available 24/7. Now Microsoft recently announced that they will no longer include Microsoft-Hosted Tier1 Sandbox environments with the Dynamics 365 Financen / SCM license and we will no longer be able to purchase additional Tier1 sandbox Addons. The preferred solution is to use Cloud-Hosted environments instead.

No more Microsoft-Hosted Tier1 environments

Microsoft-Hosted vs. Cloud-Hosted

From a technical standpoint there is no difference between a Microsoft-Hosted or a Cloud-Hosted environment. Both solutions deploy a Windows Server VM in Azure. In both cases the deployment is managed via Lifecycle Service (LCS).

LCS management of a Cloud-Hosted environment

Artefacts of a Cloud-Hosted Dynamics 365 FO Tier 1 environment in Azure

However, there are 3 major aspects to consider:

One big difference is the pricing model. Microsoft-Hosted environments (or Addons) come with a fixed (!) price per month while Cloud-Hosted environments deploy on an Azure subscription and therefore are billed like a classic IaaS (aka. virtual Machine in Azure). Make sure to calculate the costs (!) and turn of the environments if not needed.

Another difference is the ability to choose the sizing of the deployed environment. In contrast to Microsoft-Hosted Tier 1 environments, you are now free to choose a sizing that fits your needs e.g. more (or less) RAM, CPU, Premium SSD storage, etc.

Moreover, in contrast to Microsoft-Hosted environments, we now get an Admin account on our machines. It was understandable that Microsoft tried to lock down the cheap VMs to prevent the misusage with anything else then Dynamics 365. Since we own and pay the VM in a Cloud-Hosted environment its more than fair to have Admin access on the machine.

Video: How to deploy a Cloud-Hosted Dynamics 365 Tier1 developer VM

Make sure to visit my Youtube channel and watch how to deploy a Cloud-Hosted Dynamics 365 FO developer VM using an Azure Subscription.

Update: Management Certificates

The use of management certificates is not supported when using a CSP Azure Subscription. Use a user-connection instead.

Update: Provisioning Admin User

Please note that the user deploying the environment is provisioned as the administrator. Microsoft-Hosted environment had to be signed off using a user from the customer tenant. I’d recommend to stick to this process when deploying a Cloud-Hosted environment

Start and open a specific record in Dynamics Ax 2012

1. July 2020 Leave a comment

At work we recently discussed ways to startup Dynamics AX 2012 and navigate to a specific record. The requirement was to open Dynamics AX from a DMS client that manages invoices and other documents.

There are different approaches to achieve this goal. One way is to use the Startup Command framework which is used to instruct Dynamics to execute several functionalities during startup e.g. compile, synchronize or navigate to a menu item. In order to startup a menu item, you provide an XML file which contains the menu item name and point to this file from the .axc Dynamics AX configuration file.

Startup Dynamics AX 2012 with an XML configuration file

Reference the record in the startup XML file

For many forms in Dynamics AX it is sufficient to call the corresponding menu item with an Args object that holds the record. To specify a record in Dynamics AX you need to provide at least the TableId and the RecId. For example the Customer “Adventure Works” can be defined by using TableId 77 (CustTable) and the RecId 22565422070. Add two additional attributes RecId and TableId to the XML file which is used to open the CustTable form. The XML file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<AxaptaAutoRun 
 exitWhenDone="false"
 version="4.0"
 logFile="$HOME\axEXProd.log">
<Run 
 type="displayMenuItem" 
 name="CustTable" 
 RecId="22565422070" 
 TableId="77"/>
</AxaptaAutoRun>

Modify the SysAutoRun.execRun() method

At the SysAutoRun class, open the execRun() method. At the top declare the following variables:

RecId recId;
TableId tableId;
Args arg = new Args();
Common common;
DictTable dictTable;

At the bottom, find the place where a menu item is started. Before the if(mf) statement add the following code to read the RecId and TableId from the XML file and select the corresponding record:

recId = str2int64(this.getAttributeValue(_command,'RecId'));
tableId = str2int(this.getAttributeValue(_command,'TableId'));
if(recId != 0)
{
   dictTable = new DictTable(tableId);
   common = dictTable.makeRecord();
   select common where common.RecId == recId;
   arg.record(common);
}

Within the if(mf) block, add the Args object when the menu fuction is called to pass the record.

mf = new MenuFunction(name, menuItemType);
if (mf)
{
   this.logInfo(strfmt("@SYS101206", mf.object(), enum2str(mf.objectType())));
   mf.run(Arg);
   result = true;
}

Test your configuration

Now you can test your configuration. Create a new .axc file and point it to the XML file. Make sure the XML file has a valid TableId and Recid property. Start Dynamics AX using the .axc file and the defined menu item should open and view the record.

Power Automate: Deploy and Execute an Ethereum Smart Contract

11. May 2020 Leave a comment

Power Automate (aka. Microsoft Flow) is a great cloud-based tool to automate all possible tasks. There is a Ethereum connector (Beta) that can be used to deploy a Smart Contract to an Ethereum Blockchain network and execute functions.

Ethereum Network

You need to connect to an Ethereum network. There is a fully managed Blockchain Service in Azure. I’m running my private network with Proof-of-Authority. At the Azure management portal, go to the transaction node to get the required information to connect.

Smart Contract

I’m using Visual Studio Code with the Ethereum Blockchain Development SDK to implement a Smart Contract in Solidity. You can find the link to the SDK at the Azure Blockchain Service portal.

Blockchain Development Kit for VS Code — VS Code with Azure Blockchain SDK

The SDK requires a lot of other software products to download and install. I found that the solidity compiler installed was newer than expected. As result the demo smart contract you get from the SDK did not compile. The simplest solution was to change the pragma of the contract

pragma solidity >= 0.5.16 <= 0.7.0;

ABI and Bytecode

In order to automate the deployment of a Smart Contract via Power Automate you need to provide the ABI and Bytecode. Both can be found in VS Code, at the build directory in the context menu.

Power Automate

You can directly provide the ABI and Bytecode in the Deploy Smart Contract action. However, I decided to place both in an Azure Table Storage and fetch it from there. To do so, I create a table with a column for the Bytecode, a column for the ABI and a name.

Store ABI and Bytecode in Azure Storage Account

The first step in my flow is to connect to the Azure Storage account and get the smart contract I need. The result from the storage is a JSON string which is parsed so the ABI and Bytecode is available for the next steps

Deploy Ethereum Smart Contract from Flow — Fetch the smart contract binaries from the storage account

Next the Deploy Smart Contract action is used to deploy the contract. There you need to provide the connection to your Ethereum network. In my example there are two parameters for the constructor and for testing purpose these values are hardcoded. In real life you would provide values from the calling sources. The third parameter for the connector action requires the Bytecode which is taken from the storage account. The result from the deployment is the smart contracts address which is stored in a flow variable.

Deploy a Smart Contract to a private Ethereum Blockchain Network — Deploy a smart contract

Interacting with the smart contract

After the Smart Contract has been deployed to the Ethereum Blockchain Network, use the Execute Smart Contract Function action in the flow. For each step you have to provide the address, the ABI, the name of function and the parameter as JSON string. A function without parameters has to be called with {} because the parameter property is mandatory.

Execute a Smart Contract Function via Flow — Execute a Smart Contract function via Power Automate / Flow

Here is an example for a function with some parameters. These parameters have to be provided as JSON string in Flow.

function SetupMachine(int sawLength, 
                      int waterTemp, 
                      int rpm,
                      int speed) public
    {
        if (State != StateType.Assigned)
        {
            revert('Assign to a machine first');
        }

        SawLengthMM = sawLength;
        WaterTempDgrC = waterTemp;
        ExtruderRPM = rpm;
        ExtruderSpeed = speed;

        State = StateType.Setup;
        Worker = msg.sender;
    }

Call an Azure Function from X++ in Dynamics 365 Finance / SCM

2. April 2020 Leave a comment

Create an Azure Function

Azure Functions are simple way to pack and provide business logic as web service without worrying about hosting a web server. Azure Functions can be implemented in different programming languages like C#, JavaScript, PHP, Java, etc. and can be hosted on Linux and Windows with different runtime environments that feed your need.

In the Azure Portal click + Create a resource and search for Function App:

In the next screen choose a subscription and create a resource group (or use an existing one if you like). Provide a useful name and choose code as Publish method. Select .NET Core 3.1 as runtime stack and a region that is near your location:

Configure the Azure Function App to use .NET Core 3.1

Click Review + Create to create the Azure Function. It takes a view minutes to provision all the required elements:

Click on Go to Resource. Next to the Functions group click + to create a new function and select In-Portal to edit the function code direct in the browser:

Choose the webhook + API to create a demo function that can be called via HTTP POST.

This will create a function that takes a name as parameter and returns “Hello ” + the parameter name.

You can test the function by using Test tab on the right. The function takes a JSON string with a name parameter and returns a simple string.

Test the Azure Function with a JSON string

Call the function from X++

In the azure portal get the function URL with a function key. Copy the URL with the key:

Copy the Azure Function URL with function key

In Visual Studio create an X++ class with a main method for testing. Use the System.Net.Http.HttpClient class to call the service. The content is a JSON string encoded in UTF-8 with a name parameter and value. In this example the name is Dynamics:

System.Net.Http.HttpClient httpClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpContent content = new System.Net.Http.StringContent(
        "{\"name\":\"Dynamics\"}",
        System.Text.Encoding::UTF8,
        "application/json");

At the moment X++ does not support the await keyword for asynchronouse calls. The workaround is to use the Task.Wait() method. Call the service with your function URL async and get the content of the call:

var task = httpClient.PostAsync("https://<YOUR_FUNCTION_URL>",content);
task.Wait();
System.Net.Http.HttpResponseMessage msg = task.Result;

System.Net.Http.HttpContent ct = msg.Content;
var result = ct.ReadAsStringAsync();
result.Wait();
System.String s = result.Result;

info(s);

Start the class from Visual Studio. The result should look like this:

Call the Azure Function from Dynamics 365 Finance

Connect to the SQL database of a Dynamics 365 Finance Test instance

18. February 2020 Leave a comment

In Dynamics 365 Finance / SCM we can no longer access the SQL database of the production environment directly. However, we can access the SQL database of the Acceptance Test instance. All required information can be found in LCS. I’ve made a video where to find this information in LCS and how to connecto to the SQL database.
