Getting started with Azure Data Factory for Dynamics365 CRM consultants

The majority of Dynamics 365 CRM projects typically include some initial data load/migration activities as customers don't start from a blank sheet. Besides initial load of data there might also be a need for data integrations - there are a  number of solutions for data migration or data integration with Dynamics 365 CRM - this post will explain why you should strongly consider Azure Data Factory as a possible option.. 

Besides the obvious writing code as an integration option, you can also consider a third party solution and there are many good solutions on the market to meet integration needs e.g.  Tibco Scribe or the KingswaySoft SSIS Integration toolkit for Dynamics 365 .  But if you are looking for something with minimal initial cost investment (no separate licensing fee), quick start-up time and fully cloud based (no virtual machine/server environments needed) Azure Data Factory is a great fit. 

This is why - in my opinion -  technical Dynamics 365 CRM consultants should be at least aware of the  capabilities of Azure Data Factory and setup simple data pipelines.

Azure Data Factory is a managed cloud service meant for building complex, hybrid ETL/ELT pipelines that integrate data silos and can include big data and machine learning transformations.

Azure Data Factory provides an easy to use drag and drop interface where you use activities/tasks to transformation, move and copy your data from over 100+ supported data sources within the Microsoft stack or non-Microsoft (Salesforce, SAP, etc…). Azure Data Factory also has full support for running existing SSIS packages on its cloud infrastructure and last but not least it has a flexible pricing model with low initial costs. As expected from an enterprise platform it also provides great DevOps integration - something which I will cover in a next blog post (always setup Git integration for Azure Data Factory - it will make the editing experience a lot easier - see below in the Tips & tricks section for more details).

Below is a visualization of the different building blocks in  Azure Data Factory:

• A data factory can have one or more pipelines which group together activities which define the actions to perform on your data. (See  Pipelines and activities in Azure Data Factory for more details)
• These activities use datasets as inputs and outputs. A dataset identifies the data in a specific data store. (See Datasets in Azure Data Factory for more details)
• Before you can create a dataset you need to specify the linked service to link your data store to the data factory. The dataset represents the structure of the data within the linked data store and the linked services defines the connection to the data source. (See Linked services in Azure Data Factory for more details)
• The pipelines need to run in a compute infrastructure used by Azure Data Factory to allow for the different types of data integration capabilities. There are three types of integration runtime types (Azure, Self-hosted and Azure SSIS) and depending on the required capabilities and network support you will need to use on or the other. (See Integration runtime in Azure Data Factory)

Tips & tricks:

ADF has a connector which supports both Dynamics 365 (cloud version) as well the legacy on-premise versions of Dynamics CRM (version 2015 and higher) -   See Copy data from and to Dynamics 365 (CDS/Dataverse) or Dynamics CRM by using Azure Data Factory for more details). To be able to use on-premise versions of Dynamics CRM, the environment needs to be setup with  Internet-facing deployment (IFD) - info on the ADF connector information to on premise CRM see Dynamics 365 and Dynamics CRM on-premises with IFD is found on the same documentation page

• Setup Git integration for Azure Data Factory - by default, the Azure Data Factory user interface experience (UX) authors directly against the data factory service (live mode). Even when you are not deploying Azure Data Factory artifacts from source control you will benefit from the better developer experience when git integration is enabled.
• For the copy activity, you are required to set the Write Behavior to Upsert when  you use Dynamics 365 CRM as a destination (sink). You will need to provide an alternate key or you  can  leave the alternate key blank when you use the internal ID of CRM within your mapping (See Azure Data Factory: Update an existing record using Dynamics 365 Internal Guid for more details)

How to disable multi factor authentication (MFA) for a Dynamics 365 trial environment

 You might have noticed that if you now setup a new Dynamics 365 trial environment, users who login are greeted with "Help us protect your account" which requires to setup multi factor authentication (MFA) even for accounts in trial/demo tenants. This is part of the Azure Active Directory security defaults. 

To get rid of this setting you need to login to https://portal.azure.com and change this setting for the Azure Active Directory used by your demo/trial tenant. Navigate to Azure Active Directory in your subscription and select Properties in the left navigation pane. At the bottom of this screen, you will find the Access Management for Azure resources section.

Click the link Manage Security Default in this section and change the setting to Enable security defaults No.

Power Platform and Dynamics 365 API request entitlements

Based on the number and the different types of licenses that you have within your Office 365 tenant you are granted a specific number of API request entitlements in a 24 hour window. For more details take a look at Request limits and allocations (Microsoft documentation)

It is important to keep in mind that these entitlement limits are different from the service protection limits  which are already enforced today.

It is time to start reviewing your architecture and consumption of API requests on Power Platform and Dynamics 365 as Microsoft announced that they will start enforcing these limits once the transition period ends (no date available yet in the official documentation - last updated February 2d 2021) - see Power Platform > Licensing > Request limits and allocations for more details.

Quick tip: changing the access for a Teams recording in Microsoft Stream

 Up until now a Microsoft Teams recording is published in Microsoft Stream (this will change in early 2021) and  the Microsoft Teams recording is only accessible to a limited set of people. 

If you are the meeting owner, you can change permissions and allow people without access to view a meeting recording. Open the meeting in Stream and select   More options button > Update Video Details. 

This will open a new screen, in which you can tick either "allow everyone in your company to view this video" or you can share the recording with specific persons.

MB-600 Dynamics 365 and Power Platform solution architect exam prep and beyond

The last couple of weeks of 2020 I have been prepping for Exam  MB-600: Microsoft Dynamics 365 + Power Platform Solution Architect which I passed end of December 2020. In this blog post I will share some resources I used to study for the exam. I will also share some thoughts on what you can expect on the exam (without breaching the confidentiality - so I can't give specific questions). 

It was the first time I took a Microsoft exam online  due to the exam centers being closed in Belgium due to Covid.  The online proctored exam went quite smoothly but it did make me a little more nervous  especially given some of the horror stories I had heart about these type of exams.

For any Microsoft exam you start by looking at the detailed skills outline document. The MB-600 exam skills outline document  contains an overview of the different topics, you can find this document on the exam details page. Make sure to always look for the latest version since the exam requirements might get updated a couple of times every year - which is logical given the rapid evolution of the platform.

As part of the preparation I started with the MB-600: Microsoft Power Apps + Dynamics 365 Solution Architect Virtual Training Series (May 2020) for Microsoft partners - a 3 part on-demand webinar series  of about 2 hours per topic:

• Becoming a solution architect for Dynamics 365 and Power Platform (116 minutes)
• Discover customer needs and propose a solution (114 minutes)
• Work with requirements and perform fit-gap (115 minutes)

There is an overlap of this training with the Microsoft Learn learning paths which are also outlined on the MB-600 exam details page - Architect solutions for Dynamics 365 and Power Platform

I also started following a number of sessions from the MB-600 virtual study group initiative where a number of consultants share their thoughts on the exam - they will cover all content in 10 different sessions/webinar sessions. The content of the study group is largely based MB 600: Microsoft Dynamics 365 + Power Platform Solution Architect - Revision Guide (Recording are only accessible for CRMUG members)

• Session 1 recording  MB-600 virtual study group Solution architect's role (November 6th 2020)
• Session 2 recording  MB-600 virtual study group Initiate solution planning (November 13th 2020)
• Session 3 recording MB-600 virtual study group (November 20th 2020)
• Session 4 recording  MB-600 virtual study group Capture requirements (December 4th 2020) 
• Session 5 recording MB-600 virtual study group Perform Fit gap analysis (December 11th 2020)
• Session 6 recording MB-600 virtual study group Design process and topology  (December 18th 2020)
• Session 7 recording MB-600 virtual  Lead the design process part 2 (January 10th 2021)

In hindsight (after passing the exam) all of these resources provide a lot of information about the role of solution architect, the type of activities he/she engages in during the different phases of a customer engagement (Initiate & design, Implement, Support and evolve) but they are not enough for passing the exam. The exam contains quite a few technical questions that you should be prepared for on some of the topics on integration patterns using Azure, Dynamics 365 security model, ALM for Power Platform and Dynamics 365, basic understanding of the capabilities of all of the different products in both Power Platform (Canvas and model driven apps, Power BI, Power Automate Flow, Power Virtual Agents, PowerApps Portals) and Dynamics 365 (Sales, Customer Service, Field Service, etc...), ALM for Power Platform and Dynamics 365, ... 

There are the standard multiple choice questions which you also encounter but what was new for me in this exam was the use of fictional customers case studies which will serve as input for a set of questions afterwards. Normally the MB-600 exam is the culmination in a series of exams for attaining the title of but I only took this last exam up until now. So probably there is an overlap in the technical content covered as part of the other exams.

Team member license enforcement coming up - deadline 31th of January 2021

Technical enforcement for Dynamics 365 Team Members licenses purchased or transitioned after October 1, 2018 will come into effect on January 31, 2021 (extended from the original date of April 1, 2020) for customers with online environments.

This means that user with Team member license will not be able to access custom model-driven apps or some of the standard first party modules they now have access such as the Customer Service Hub or Sales Hub. (for more details check out  Dynamics 365 Team member licenses (Microsoft Docs).

Team member users will only be able to use specific designated app modules:

• Customer Service team member - must be manually installed is not available by default
• Sales team member - available by default in all tenants

You can extend the existing apps and add  both CDS core entities or your own custom entities into the app but you are restricted to 15 entities. There is a Team Member conformance report available for download in the Power Platform Admin Center. Go to the Common Data Service area in the Analytics section, and then select Download to access the report,  use the Change filters link to filter the report by Environment and Date.

Dynamics 365 and Power Platform Wave 2 2020 updates - learn to surf the waves

All Dataverse (the new name for Common Data Service) and Dynamics 365 online environments hosted in EMEA region recently received over 200 new updates and features as part of the wave 2 2020 release. This release cadence is a part of Microsoft's one version vision for the  Dynamics 365 platform (take a look at Dynamics 365 Customer Engagement release version transparency for more details)

Update: Just noticed that Microsoft announced the dates for the next release wave 1 for 2021 - release plan will be available on January 27 and early access will be available on February 2021

It is quite challenge to keep track of the fast pace of innovation/change on both Power Platform and Dynamics 365 so I just made this small recap of things I want to check out in the coming weeks. Luckily there are bloggers like Nishant Rana who do a lot of the hard work for you and already dive into the new releases quite early  - he delivered a whole set of blog posts on Dynamics 365 Release 2020 Wave 2

• Insert knowledge article in e-mail - 2020 Release Wave 2
• E-mail file attachment enhancements in Dynamics 365 - 2020 release wave 2
• Configure Customer Service Analytics and Insights in Dynamics 365 Customer Service Hub (Preview)
• App switcher, back option and other enhancement in 2020 release wave 2

The new/updated relevance search feature is definitely something I will look into as I think it will provide a lot of value for customers:

• Introducing the new search experience in model driven apps
• Introducing the Relevance Search API and Using relevance search to search for rows and Dynamics Relevance search just got relevant

Covid-19 has turned B2B sales into an overwhelming digital experience, so the new sales accelerator, relationship intelligence and the advanced forecasting functionality - all part of the Dynamics 365 Sales Insights module -  are  capabilities to take a look at as they will support the new reality of B2B buyers preferring a digital buying experience.

Welcome to Azure PowerShell Az module, goodbye to AzureRM

As outlined on Overview of Azure PowerShell (AzureRM) - Microsoft new recommends you to use the Az PowerShell module (released in October 2018) to interact with Azure.

The Azure Az PowerShell module  introduces a number of benefits such as shorter commands, cross-platform support and increased stability.  From a supportability perspective, the AzureRM module is still officially maintained and will receive critical fixes through February 2021. I recommend keeping tabs on the supportability section of the Azure Az PowerShell module documentation page as this date has already shifted.

When you first start to use the connect-AzAccount - you might receive a warning that you still have the old AzureRm modules installed. If you have installed the AzureRM PowerShell modules using a MSI package, you must uninstall it through the Windows system rather than using PowerShell

A nice enhancement is the warning around having multiple Azure subscription linked to the account that you use to login  (something quite common for cloud consultants)  - as outlined in the warning  you can use  Set-AzContext to select another subscription.

Provisioning Azure Automation using Az.Automation module

Azure automation is a cloud based service which allows you to automate, configure and install updates across hybrid environments. Azure Automation focuses on an infrastructure perspective and allows you to  build/deploy resources, handling updates and configuring all type of resources (not only in Azure but also on premise). 

Coming from a development background and using mostly Azure PAAS components (Azure Functions, Web Apps, Web Jobs, etc..) I had not used it until recently when I got a request from the DBA team for setting up jobs to resolve index fragmentation by reorganizing and rebuilding index for which they suggested to use Azure Automation.

The core component in Azure Automation are runbooks which contain the automation code that you want to use to perform the automation task at hand.  There are a number of runbook types:  (textual) PowerShell runbook, graphical runbook, PowerShell workflow runbook and Python runbook

You can use the Azure Az PowerShell module to create an Azure runbook using the following steps:

• Create an Azure Automation Account with New-AzAutomationAccount
• Create the runbook with New-AzAutomationRunbook
• Import PowerShell code using Import-AzAutomationRunbook
• Publish runbook - before you can start using a runbook, you have to publish it - Publish-AzAutomationRunBook
• Create a schedule and associate it to the runbook - schedules can be shared by multiple runbooks - using New-AzAutomationSchedule and Register-AzAutomationSchedule

Notes on getting started with GraphQL - working with Eurex data

Although I had heard the term GraphQL (www.graphql.org) before I never took a look at it. As outlined on https://graphql.org/ , GraphQL is a query language and specification for your APIs which was initially developed by Facebook as a more flexible and efficient alternative to REST (See GraphQL: a data query language for some background). 

I started looking at the GraphQL to explore the Eurex T7 Reference Data API.  Eurex is the largest European futures and options market and primary deals in Europe-based derivatives (interest-rate derivatives, equity index and equity derivatives and even more exotic derivatives like volatility derivatives, FX derivatives, etc...)

To learn which queries are supported you can use GraphQL introspection to get information about all available requests, filters and response - below is an example of a Postman request

Another easy way to explore the API which is also outlined on the Eurex Reference data API start page is using the GraphQL Playground for Chrome extension

You can also use graphql-voyager to visually explore GraphQL API as an interactive graph - a live demo environment is available as well where you add your own APIs - GraphQL Voyager (apis.guru)

Reminder: quickly format XML files with Notepad++

Notepad++ is one of my favorite tools but it is not always easy to remember which plugin you need to install again after moving to a new laptop. So quick reminder: if you want to format XML files in Notepad++ the easiest thing to do is installing XML Tools using the Notepad++ plugins manager. Next you can use the Plugins>XML Tools>Pretty  print

Automate your PowerApps Canvas apps test in your DevOps Pipeline

Some of you are already using automated UI testing for PowerApps model-driven apps (or for Dynamics 365 App extensions) using Easyrepro - the UI automation test library for Dynamics 365 and CDS  but it is also possible to Automate your canvas app tests in your DevOps Pipeline. 

The PowerAppsTestAutomation project on Github abstracts the complexity of writing code to login the canvas apps, add application logging and executing a test case or a test suite.

Access token endpoint versions in Azure AD

You might have noticed that there are two different urls that you can use for retrieving an access token in Azure AD:

• https://login.microsoftonline.com/<tenantid>/oauth2/token
• https://login.microsoftonline.com/<tenantid>/oauth2/v2.0/token

And although most of the time it is better to use the more recent version, I did wanted to know the difference between both. After deciding that in this case google was not my friend I reached out a colleague @KevinDockx  (Definitely check out his Pluralsight training Microsoft Azure for .NET developers - Building secure services and applications )

Evolution of Microsoft identity platform explains how Azure AD developer platform evolved towards the new Microsoft identity platform. In short the /oauth/token endpoint is part of Azure AD for developers and /oauth2/v2.0/token is linked to Microsoft identity platform.

If you need to decide whether to use Microsoft identity platform (v 2.0) or Azure Active Directory (v1.0) endpoints - definitely take a look at Why update to Microsoft platform (v2.0) and check out the limitations section as well.

In short try to use the v2 as much as possible since it provides more features and is more in line with common standards. The v1 endpoints will still exist for quite a while and as far as I know there is no end of life announced (yet) but Microsoft did already announce the deprecation of the Azure Active Directory Authentication Library (ADAL) - see Migrate applications to Microsoft Authentication Library (MSAL). Everything evolves quite fast and there even is a newer alternative for MSAL called Microsoft Identity Web 

You might also take a look at OpenID Connect (OIDC) which is an authentication protocol built on OAuth 2.0 since Microsoft Identity platform is compliant with this standard as well - see Microsoft identity platform and OpenID Connect protocol for more details
