What’s Rebase and Merge in Azure Devops…Quick Recap

Hi Folks,

Yesterday I was working with Azure DevOps repository for my project. My local Develop branch is behind the Main branch by few commits, I want to get the latest commits into my local and include those from the Main branch also in to my Develop branch.

It is then I got to know whether to use GIT Merge Command or GIT Rebase Command. And here you go my findings on the same….

I got to know the details, official Git manual states that rebase “reapplies commits on top of another base branch”, whereas merge “joins two or more development histories together”. In other words, the key difference between merge and rebase is that while merge preserves history as it happened, rebase rewrites it. Let’s start with an illustration…for better understanding…followed by the differences…

MergeRebase
Git merge is a command that allows you to merge branches from Git.Git rebase is a command that allows developers to integrate changes from one branch to another.
In Git Merge logs will be showing the complete history of the merging of commits.Logs are linear in Git rebase as the commits are rebased 
All the commits on the feature branch will be combined as a single commit in the master branch.All the commits will be rebased and the same number of commits will be added to the master branch.
Git Merge is used when the target branch is shared branchGit Rebase should be used when the target branch is private branch

Actually talking both do mean the same purpose and have their own uses, but at the end of the day it is completely up to your ALM strategy/methodology. I preferred to use Merge instead of Rebase just that my branch is shared branch and for simplicity.

Hope this helps…

What’s the new table type being introduced..?

Hi Folks,

While you may have noticed this or not, but it’s real. Now Dynamics 365 CE existing table types have a new companion called Elastic, it is yet to be announced.

However let’s take a quick look of the table types showing up when you were trying to create a new one in Dataverse.

While everyone is aware about Standard, Activity, Virtual types in Model Driven Apps. Elastic tables are new tables which came in to Dataverse and probably it will be announced in the upcoming Microsoft Build 2023.

From my view, Elastic tables were

1. Built similar to the concept of Elastic Queries in Azure which is usually meant for the purposes of Data archiving needs.

2. You can scale out queries to large data tiers and visualize the results in business intelligence (BI) reports.

3. Elastic Query provides a complete T-SQL Database Querying capability on Azure SQL, possibly Dataverse.

Hope we get all the capabilities released with Elastic Queries of Azure SQL be released in Dataverse as well.

Changing Data Type of Primary Column now allowed in Model Driven Apps

Hi Folks,

Do you know you can change the Data type of an Primary column between Single Line of Text and Autonumber even after creation of your entity specifying a defined Primary Name Column. There is a catch….

So let’s see…

I first created a brand new Table called Demo Table and kept the Primary Column as Single Line of text. Earlier once the table is created, you will not be able to change the Primary name column if you wish to, the only way was to delete the table and re-create it with the correct type. But now you can change the type of the column at least to a unique autonumbering.

I want the Primary Name column to be unique, but when I look at the data in my table captured, I see many duplicates.

So let’s change the data type of the primary column data type to Autonumber.

The primary field look as below initially…

Select the Data Type available…

Now Select the Autonumber from the drop down available…you can optionally specify any custom prefix which you want for your Autonumber…and click Save and publish the customizations.

Now go back to your model driven app and then try creating a new record for the respective entity.

Since it was a primary field column, it is by default made mandatory…what’s up…the Autonumber column data type change is not reflecting….this is the same even if you check and publish the solution multiple times. Neither you can’t specify the field value because you already choose this to be an Autonumber and system should create it by itself.

If you were scratching your head, then this simple tip will help…

Just make the field read-only from the form where this field is being referred, so you don’t need to really enter value for it…then publish the customizations.

Once you have done…

Now try to save the record..

There you go, you can see an Autonumber being populated in the primary field…

Power Platform Requests usage…check it out in a no code way now in Admin Center(Preview)

Hi Folks,

As a Power Platform Admin/Consultant…did you often worry about your Power Platform Request Limits and usage left…? Do you receive warning messages from Microsoft regarding the usage of your database exceeded..? Want to see what are Custom Plugin Errors encountered while using your Model Driven App targeting Dataverse….then want to consolidate them and forward to your team to look into the issues without much efforts….then you were in the right place…

Just login with your credentials to admin page https://admin.powerplatform.microsoft.com/.

Expand Resources to the left…to find the Capacity menu

If you just want to know only the data usage, then you can ahead and click on Download as shown above to get one.

Want to get in depth analysis…then click on Details as highlighted in the same snap above.

This page shows your Database usage/File usage and respective categorizations by table as below..

These are reports which I was able to extract from my trial environment, however all the reports were not available currently in my region. Yes, this is expected as this feature is still in preview and not recommended for Production Projects as of now. Definitely in the future…

Note:

  1. Many people including me till now thought that Plugins or at least any operation performed within Model Driven app will not be counted for the API request limits. But…
  2. If the requests are making CRUD, assign, or share–type requests, they’ll count except internal requests. For classic workflows, this includes actions such as checking conditions, starting child workflows, or stopping workflows.
  3. You should never use any third party tools for Integration whenever you were facing any request limit issues.
  4. Request limits are applied differently for licensed users and Non-licensed users.
  5. You can add more capacity to any of your products by assigning your environment in the manage addons page.

Hope you found this post helpful…

Stop using OData V2.0 endpoint going further for your implementations….!

Hi Folks,

This blog is just to let you know why you should stop implementing OData calls using V2.0 version. I am pretty sure almost every Dynamics CE project out there have used this OData calls definitely in their implementations from quite some time. While some of new implementations have replaced the logic using Web API, still some people go with using OData V2.0 calls to build their functionality using JavaScript.

Microsoft had actually planned to remove this endpoint from April 30, 2023. But they deferred this because many projects are’nt yet prepared for removal of this end point and help the customers prepare for this transition to Web API end point.

Identify if you still using OData V2.0 end point, actually Organization Data Service is an OData V2.0 endpoint which was introduced with Dynamics CRM 2011..it’s deprecated way back with Dynamics 365 CE version 8.0.

So now, how to identify where and all you were using OData End Points in your code…you shouldn’t expect that existing code will work with only minor changes and this work can be taken at a later stage. This was a high priority warning message from Microsoft stating the removal, so I urge all of you to be prepared for this removal very soon and you shouldn’t be surprised.

So where to change…..?

Below are the places where you should change your way of implementation and align with Microsoft…

  1. The Organization Data Service using this end point /XRMServices/2011/OrganizationData.svc in Javascript, you can find it out with the help of the checker service rule web-avoid-crm2011-service-odata for identification. This can be code which was making OData calls to perform CRUD Operations on the current table or related table.
  2. Check any other code, including PowerShell scripts, that send requests to this endpoint: /xrmservices/2011/organizationdata.svc.
  3. Cross Check your Power BI reports or Excel Data sources that may be using this endpoint.

Note:

This announcement does not involve the deprecated Organization Service SOAP endpoint, meaning using Organization service in plugins. At this time, no date has been announced for the removal of that endpoint. At the time of writing this blog post, Microsoft didn’t announce whether this removal is only for Online or On Premise Versions.

Hope this saves time and effort implementing your Dynamics CE Solutions…

Design your Data Model efficiently with Star Schema for Power BI – [Must Know]

Hi Folks,

This blog post isn’t about any use case, rather it just highlights the importance and benefits of designing your data model for your reporting requirements. Every Power BI Developer should consider this at first place.

When designing your Power BI Reports, Data Modelling is the first step whenever you want to work with the Power BI dashboards or reports which plays a very key role. Coming to Schemas, I can say there are two schemas namely Star Schema and Snow Flake Schema. This blog post mainly talks about Star Schema for your Power BI Report/Dashboard design.

With Star Schema, Power BI data models are optimized for performance and usability. While every consultant try to create stunning visuals, they also need to focus on their data model before spending time on their report design.

Star Schema revolves around 2 types of tables in general, they were Fact tables and Dimension tables(talks about the business entities).

Fact table is central table in star schema. Dimension table are the tables which were connected to Fact table using a one-to-many or many-to-one relationship. Generally, dimension tables contain a relatively small number of rows. Fact tables, on the other hand, can contain a very large number of rows and continue to grow over time. So now let’s see how a star schema looks like and taken from Adventure works sample.

Image shows an illustration of a star schema.

Main point to note here is Normalization and Denormalization capabilities which are two great concepts to understand how star schema can help increase the performance of your dataset.

Star schema requires normalized tables and SnowFlake Schema needs denormalized tables. The design fits well with star schema principles:

  • Dimension tables support filtering and grouping
  • Fact tables support summarization

You can visualize the relationship as per the below diagram…

These concepts include, I will brief about the below topics which were not widely popular yet must know for designing an efficient Power BI Dataset.

Last but not the least, I should say that following and designing your data model using Star Schema is a best practice suggested by Microsoft.

You can lookout for references if you want to see video which can be of great help for you to understand the star schema mainly for beginners…

Fixed – Invalid data from the network error in the custom page – Power Apps / Dataverse

Reblogged on ecellorscrm.com…

Nishant Rana's avatarNishant Rana's Weblog

Recently in one of our custom pages, we were getting the below error

“Invalid data from the network”

We had this setting “Formula-level error management” as On, switching it off was hiding this error on the page.

To fix it we tried removing the fields one by one to figure out the issue. Eventually, we saw the error was going away if we remove one of the option set fields from the gallery or comment it’s formula. Later when we removed and added the field back in the gallery and the error got fixed for us.

The page loading properly without the error –

Hope it helps..

5 Power BI Errors..you often encounter – Fixed

Hi Folks,

Here I would like to give some tips regarding Power BI Errors which will be encountered in everyday job of anyone who’s going to or work with Power BI Dashboards or understand any existing dashboards and integrate them with Model Driven Apps. You aren’t alone…so let’s gets started…

Error 1: Unable to open document

Fix:

You were not on the latest version of Power BI desktop with which it was authored. You can quickly check the version by navigating to Help –> About

You should see a update icon as below

Clicking on it will take you to the respective page having the latest update from where you can update it.

Error 2: Class not registered error

Fix:

This can happen when you were trying to open an existing dashboard which was created by you or shared by someone to you, might be because you have two versions of Power BI Desktop installed..in your machine..like shown below.i.e.

  1. Installed Power BI from Microsoft Store
  2. Installed Power BI from Microsoft Downloads

Make sure you choose the right one which you have used earlier to develop the Dashboard so that you won’t run into any issue.

Error 3: Workspace deleted

Fix:

This error can happen when you were trying to access any workspace while you were creating a Power BI Dashboard in Dynamics CE using an existing workspace, make sure you have a workspace and the logged in user have access to the Workspace.

Granting access to the workspace will fix the issue.

Error 4: One or more Cloud Datasources have been deleted

Fix:

Whenever you deploy any new Power BI report or dashboard to Power BI Service, you encounter this problem most of the times. Sometimes after making a change to a dataset or taking over ownership of a dataset, you might receive the following error:

1. Click the “Recreate cloud data sources” button.

2. Reenter credentials in the “Data Source Credentials” section for your data sources

Make sure dataset is connected to Gateway incase you have configured.

Error 5: There is no gateway to access the datasource

Fix:

The first thing to look at when you have a missing gateway is to make sure you created a data source for that gateway. Installing the On-Premises Data Gateway is not enough. That simply registers the gateway with the Power BI service and lists you as an admin for that gateway.

You then need to go into the Power BI service and create a data source for that gateway.

You can create a data source by doing the following.

  1. Select the gear icon within Power BI
  2. Select Manage Gateways.
  3. Select your gateway and then select Add Data Source.
  4. When you are done entering the information, select Add.

Xrm.WebAPI with Promise for synchronous calls in Javascript

Hi Folks,

Here is how I have quickly achieved the synchronous Retrieve multiple call using Web API and Promises with the help of JavaScript. I don’t want to make my post too detail, but I would like to share the approach.

All I want to do is to just Restrict saving the Contact creation if the Postal Code entered is not present in the system. But this call should be synchronous as the message should be shown immediately incase postal code is not found in the system and prevent saving the contact record. All you need to do is simple, just call the below function on change of Postal Code in Contacts.

Here in place of XMLHTTPRequest, I have used Xrm.WebAPI so that it won’t show a critial warning in Solution Checker.

ValidatePostalCode: function (executionContext) {
"use strict";
var formContext = executionContext.getFormContext();
var postalcode = formContext.getAttribute(Resident.Fields.address1_postalcode).getValue();
var message = "Please enter a valid Postal code; Refer to Postal Code Mappings"
var uniqueId = "cnt_postalcodenotpresent";
return new Promise(function (resolve, reject) {
Xrm.WebApi.retrieveMultipleRecords("new_postalcodes", "?$select=new_postalcode&$filter=hsg_postalcode eq '" + postalcode + "' ").then(
function success(result) {
var isNotFound = false;
if(result !== undefined)
isNotFound = result.entities.length === 0 ? true : false;
if (isNotFound) {
var errorMessage = "Postal Code Mapping is not present for the given postal code"
formContext.ui.setFormNotification(errorMessage, "ERROR", uniqueId);
}
else {
Resident.isValidationNeeded = false;
formContext.ui.clearFormNotification(uniqueId);
formContext.data.entity.save();
}
// return true or false
resolve(isNotFound);
},
function (error) {
reject(error.message);
//console.log(error.message);
}
);
});
}
