SAP Error Message - Details

• Message type: E = Error

• Message class: PPEMPL -

• Message number: 045

• Message text: Model definition &1 has impermissible object type: &3

What causes this issue?

In Customizing for model definition, the system has found data records
in the database that, following a conversion, would not have a clean
separation between MPL objects and PVS objects.
This is because the model definition contains one object type that is
neither intended for conversion nor lies in the customer namespace, and
one object type that does lie in the customer namespace.
After the conversion, therefore, one of the objects would be an MPL
object the other object would be a PVS object.

System Response

To avoid inconsistencies in the database, the system does not perform
the conversion.

How to fix this error?

If the model definition is not used productively, attempt to delete it.
If you cannot delete it, correct the namespaces in the report.

Procedure for System Administrators
