How To Fix USMD5052 - Changes to data cannot be deleted without a model assignment

SAP Error Message - Details

• Message type: E = Error

• Message class: USMD5 - Master Data: Workflow

• Message number: 052

• Message text: Changes to data cannot be deleted without a model assignment

What causes this issue?

You attempted to delete master data changes of change requests that have
an inconsistent data model assignment, but you did not attempt to delete
the respective change requests. Either no data model is assigned to the
selected change requests, or an assigned data model does not exist in
the active version.
When you manually run the deletion program to delete change requests,
this action is triggered when 'space' is selected as the data model and
the deletion option for deleting master data changes without deleting
the change requests is chosen.
This function cannot be executed from the called module.

System Response

The action is terminated.

How to fix this error?

Which action is performed now, depends on what you want to achieve:
If you want to delete specific master data changes of change requests
that have inconsistent data model assignments, you have to call a
different module.
If you want to delete specific change requests that have inconsistent
data model assignments, you need to select the respective delete option
and include the deletion of the change requests.
If you want to delete the master data changes and the change requests,
you need to perform both of the actions mentioned above.
