Message text: Document class &1 not assigned to any document type and origin key
You have entered the document class and this is not assigned to any

function module with the process type <ZK>Change document class </>in
the Customizing activity

and Origin Keys</> or assign a customer function module with the process
type <ZK>Change document class </>in the Customizing activity
