Can’t delete billing profile. This is the only billing profile in the billing account- Azure (Trial)

Recently our Azure Subscription using free credit had expired and we wanted to remove the card details associated with the billing.

If we try to Detach it (and if the card is being used as the default payment), it will give us the below message

Cost Management >> Payment Methods > > Detach

“There are active or disabled Azure subscriptions on this billing profile. To detach this payment method, cancel and then delete all such subscriptions.”

And if we trying to delete the billing profile

Cost Management >> Billing profiles

We would get the below message

So first we need to delete the subscription here.

Now again we can only delete the free trial subscription after 3 days of canceling it. So we would have to try deleting the subscription after 3 days.

Trying after 3 days,

will give us the option to delete the subscription

But as we have the resources associated we will have to delete the resources first.

Navigate to All resources and delete the resources first.

After deleting the resources, deleting the subscription will be successful

Let us now try to detach the card again.

This time the Azure Subscription existing message was gone as we had deleted it, however, we were still not able to detach and it was asking to wait until the end of the billing period.

Instead of waiting till the end of the billing period – next we tried the below option

https://docs.microsoft.com/en-us/azure/cost-management-billing/manage/cancel-azure-subscription#how-do-i-delete-my-azure-account

i.e. Deleting the Azure AD Account. (through another admin user’s account)

After successful delete, we can see all the options disabled.

So basically the fastest way to remove your personal information from the Azure Free Trial is to cancel the subscription, delete it and then DELETE the account/user.

Hope it helps..

Fixed – AuthorizationFailed. The client with object id does not have authorization to perform action ‘’Microsoft.Authorization/roleAssignments/write’ over scope ‘storageaccount’ – Azure Data Lake

While configuring the Azure Synapse Link/ Export to Data Lake service, we were getting below error for one of the users.

{“code”:”AuthorizationFailed”,”message”:”The client ‘nishantr@pmaurua105.onmicrosoft.com’ with object id ‘d56d5fbb-0d46-4814-afaa-e429e5f252c8’ does not have authorization to perform action ‘Microsoft.Authorization/roleAssignments/write’ over scope ‘/subscriptions/30ed4d5c-4377-4df1-a341-8f801a7943ad/resourceGroups/RG/providers/Microsoft.Storage/storageAccounts/saazuredatalakecrm/providers/Microsoft.Authorization/roleAssignments/2eb81813-3b38-4b2e-bc14-f649263b5fcf’ or the scope is invalid. If access was recently granted, please refresh your credentials.”}

The current Role assignments of the user were as below.

To resolve it we need to give the Owner role to the user configuring the Export to Data lake service on the Storage account. (apart from System Admin role within Dynamics 365)

https://docs.microsoft.com/en-us/powerapps/maker/data-platform/export-to-data-lake#prerequisites

After assigning the Owner Role (and removing the other roles), it worked successfully.

How to setup – Azure Synapse Link – Microsoft Dataverse

Azure Synapse Link (earlier known as Export to Data Lake Service) provides seamless integration of DataVerse with Azure Synapse Analytics, thus making it easy for users to do ad-hoc analysis using the familiar T-SQL with Synapse Studio, build Power BI Reports using Azure Synapse Analytics Connector or use Azure Spark in Azure Synapse for analytics.

Posts on Azure Data Lake

As a first step, we need to create the Azure Synapse Workspace.

https://docs.microsoft.com/en-us/azure/synapse-analytics/get-started-create-workspace

Wait for the deployment to be complete. Below are the resources created as part of the deployment.

Click on Azure Synapse Link and check the Connect to your Azure Synapse Analytics workspace (preview) and specify the storage account created in the previous step

Here we have selected the Contact and System User table for export.

On clicking Save, we got this error couple of times, even though the account being used was Owner across the Azure resources. Trying save 3-4 times more, allowed the link to be created.

Click on Go to Azure Synapse Analytics workspace, opens the Azure Synapse Studio

Within Synapse Studio we can see our Dataverse Database and run query.

Similarly, we create a Power BI report with Azure Synapse Analytics (SQL DW) connector.

Copy the Serverless SQL endpoint of the Synapse workspace.

Select the Direct Query option.

Azure Synapse Link / Export to Data Lake Service – Performance (initial sync)

Recently we configured the Export to Data Lake service for one of our projects.

Just sharing the performance, we got during the initial sync.

Entity	Count
Contact	2,36,2581
Custom entity	1,61,3554

The sync started at 11:47 A.M and was completed around 4:50 P.M. – around 5 hours i.e. 300 minutes

Let us consider total records synced as 3975000 – 1613446 + 2362581 + 2 = 3976029.

So the performance here comes down to

795000 records per hour
13250 records per minutes
220 records per second.

Of course, it will vary depending on the specific environment, table / entity type, attributes in it etc. it gives us a rough idea.

Advanced configuration settings – Azure Synapse Link / Export to Data Lake service (Dataverse/ Dynamics 365)

The Export to Data Lake service now has some Advanced configuration settings available.

To learn more on Export to Data Lake service

https://nishantrana.me/2020/12/10/posts-on-azure-data-lake/

The new settings allow us to configure how the DataVerse / CRM table data is written to Azure Data Lake.

In-Place update or upsert (default)
Append Only

With the in-place update, the default setting, the file will contain the full data set, and any update in the source will update the same in the synced CSV file or the data partition, similarly, any record deleted will delete the row from the data partition, unlike Append Only where a new row will be added in case of both update and delete.

For huge volume of data, Microsoft recommends opting for Append only mode. This mode is also preferable when an organization wants to incrementally review the changed data.

The other option is to define the data partition strategy.

By Month (default)
By Year

With this option, files generated are partitioned by either year or more granular month-wise, which can be specified per-table basis.

Microsoft recommends Monthly partition if data volume is high.

Now, let us see it in action.

For the Lead table, we haven’t selected the option for advanced configuration settings and are going by default.

Append Only – No
Partition Strategy – Month

For contact, we have enabled the advanced configuration settings and opted for Partition Strategy as Year.

For Account , we have opted for Append Only as true, for which the Partition strategy option is disabled and set as Year.

The final configuration à

Within the container inside the Storage Account, we can see corresponding folders created per table/entity along with model.json as shown below.

Let us explore the Lead folder –

We can see 2 CSV created with format YYYY-MM.csv i.e. having the month part in it because we had specified Partition Strategy as Month i.e. the default value.

For Contact and Account, the Pattern Strategy was Year, so we have files generated in format YYYY.csv

Let us update one of the lead records by appending ‘Updated’ in the last name field.

After the successful sync,

we can see the record updated in the .csv / partition.

The same is the case with the contact record.

Now let us update an account record, it had Append Only specified as Yes.

Here we update the Account Name field from Litware to Litware Updated.

After the sync

We can see a new row appended with the updated record along with the original record.

Let us delete the same account record

As expected, being Append Only mode, we can see a new row added for the Litware record.

We have 2 additional rows apart from the original row, one created for update and the other for delete action.

Export to Data Lake service is Microsoft’s recommended way of synchronizing Dataverse Data with external storage, and we can see them continuously investing and adding enhancements to it.

Write batch size, data integration unit, and degree of copy parallelism in Azure Data Factory for Dynamics CRM / 365 Dataset

Let us take a simple example where we are moving contact records (.CSV) stored in Azure File Share to Dataverse or Dynamics 365 (UPSERT).

CSV file has 50000 sample contact records (generated using https://extendsclass.com/csv-generator.html) stored in Azure File Storage.

Another option of generating sample data

https://nishantrana.me/2020/05/26/using-data-spawner-component-ssis-to-generate-sample-data-in-dynamics-365/

The Source in our Data Factory pipeline.

The Sink is our Dynamics 365 / Dataverse sandbox environment, here we are using the Upsert write behavior.

For the Sink, the default Write batch size is 10.

Max concurrent connections specify the upper limit of concurrent connections that can be specified.

Below is our Mapping configuration

The Settings tab for the pipeline, allows us to specify,

Data Integration Unit specifies is the powerfulness of the copy execution.

Degree of copy parallelism specifies the parallel thread to be used.

Let us run the pipeline with the default values.

Write Batch Size (Sink) – 10
Degree of copy parallelism – 10
Data integration unit – Auto (4)

The results à It took around 58 minutes to create 50K contact records.

We then ran the pipeline few more times by specifying the different batch sizes and degree of copy parallelism.

We kept Max concurrent connections as blank and Data Integration Unit as Auto. (during our testing even if we are setting it to higher values, the used DIUs value as always 4)

Below are the results we got à

Write Batch Size	Degree of copy parallelism	Data Integration Unit (Auto)	Total Time (Minutes)
100	8	4	35
100	16	4	29
1000	32	4	35

250	8	4	35
250	16	4	25
250	32	4	55

500	8	4	38
500	16	4	29
500	32	4	28

750	8	4	37
750	16	4	25
750	32	4	17

999	8	4	36
999	16	4	30
999	32	4	20

The results show that increasing the batch size and degree of copy parallelism improves the performance in our scenario.

Ideally, we should run a few tests with different combinations before settling for a specific configuration as it could vary.

On trying to set the batch size to more than 1000,

We would get the below error à
ExecuteMultiple Request batch size exeeds the maximum batch size allowed.
