Error with task TS1000160 - Approve appraisal

Hi All,

I am implementing standard appraisal approval workflow WS01000105.

Workflow is triggering ok and all is working as expected except from standard task TS1000160 which is executed after approval.

This task executes method APPRAISALAPPROVE of BO BUS7026 in background and it generates a Runtime Error of type DYNPRO_SEND_IN_BACKGROUND.

It seems that the reason is that this method asks for a transport at the moment of changing appraisal document status from "Completed" to "Approved".

What it is confusing to me is that this is a standard task of a standard workflow.

Any help on what to do to fix this issue?

Thanks!
