Issue while posting the invoice in background using the WF-BATCH user
I am facing an issue while posting the invoice in background using the WF-BATCH user. I am using a invoice approval workflow where in when the approver approvers the invoice the invoice document get posted using a background method, which uses BO FIPP and Method POST and i am returning the Message Text to my workflow container from this method. When i see the log an exception is rasied from this method with an error message "V004: You are not authorized to change this document", but WF-BATCH is having SAP_ALL and SAP_NEW authorizations. If i try to post the invoice using the method from my user id it is getting posted. What could be the issue. Please advice.
