Plant Data deletion in change request after Approval

Hi

I am facing one issue. I am using Add on for MDGM. When CR is sumbitted with plant data it shows it is staging area while CR is in approval process.

But it auto vanishes after final approval of CR and only Basic 1 and Basic 2 data are replicated to ECC.

After verfying SLG1 it shows

USMD6573 - Change request &1 does not contain objects to be replicated - USMD6 573

Diagnosis

The change request either does not have any objects in the object list or no business object types could be found.

System Response

Procedure

If the change request contains objects, contact the system administrator.

Procedure for System Administration

In Customizing for Master Data Governanceunder General Settings-> Data Modeling-> Edit Data Model, check if business object types have been assigned to the entity types in the change request. If not, make the assignment and activate the data model.

In Customizing for Master Data Governanceunder General Settings-> Data Replication, check if all the necessary settings have been made.

Here as per me as it is add on no need to define any replication settings.Is this Correct?

Also ne need to assign business activity for type 4 entity types as it works before?

Any suggesstion?
