Removing canvas app table references using RemoveAppComponentsRequest

Posted on by ArtieLeech

We are investigating automating the creation of our Dataverse tables using CrmServiceClient.

We are trying to temporarily remove references in our canvas apps to our Dataverse tables using RemoveAppComponentsRequest, which according to this site looks like it's possible:

"You can add or remove components in an app such as sitemap, entity, dashboard"

However, running our script, using the App Id obtained from our canvas app in Power Apps studio gives the error:

Unhandled Exception: System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: appmodule With Id = <our App ID guid> Does Not Exist

If the App Id in Power Apps studio is the wrong one, then where do we find the correct guid?

The above request which works only for model driven app and not for canvas app.

If it answers your question, kindly give kudo and accept it as solution.

Thanks for your response @Prakash4691

If we can't use RemoveAppComponentsRequest on canvas apps, is there another way to temporarily remove a reference to a Dataverse table using CrmServiceClient?

Our intention is to:
remove the references to the Dataverse tables from our canvas app
rebuild the Dataverse tables with the latest schema using CrmServiceClient methods
add the references to the Dataverse tables back into our canvas app

It looks like currently app module API which supports only for model driven app. There are no API available for canvas app to perform such operation.

You have to do it through UI editor. It you want to have latest schema of the table just refresh the data source.

@Prakash4691, by using the API examples here, we've managed to automatically generate all our Dataverse tables, including relationships. So now we can always regenerate our Dataverse from scratch, which has helped, for example, when junior team members accidentally changed various aspects.

We've then added data connections to these Dataverse tables in our canvas apps.

However now, if we update our Dataverse schema scripts and run them, we need to manually remove the data connections from our apps first, re-run our scripts to freshly build the Dataverse tables, then re-add the data connections manually again.

Is there another automated approach that could be used to temporarily remove a data source from a canvas app, e.g. a Flow or something else?

Yes, that will work only for dataverse tables. Currently there are no API's or messages available for canvas app. So automation is not possible.

FYI, as per below link only messages/API's which are currently available for canvas apps.
