Get the user ID of workitem creator/Initiator
I am writing a program which has to pull out the user ID of the Initiator/Creator of workitem . Basically I have the workitem number and out of which I am to pul out the agents of the workitem through a standard FM 'RH_WI_AGENTS_GET' .
Do we have any other function module / Bapi or any other approch to pull out the Initiator/Creator of Workitem.
Waiting for Suggestions.
