Hi there,
I am having problem when calling BAPI_PO_RELEASE from VB.NET via NCo 2.0 whereas i can successfully release a PO with the same user and with the same parameter input values via SAPGui's SE37
However, when i call BAPI_PO_GETITEMSREL from VB.NET via NCo 2.0 with the same user there is no problem, i can get the returns. and of course i can do it via SAPGui's SE37.
The error i get via NCo 2.0 when calling BAPI_PO_RELEASE is :-
'SAP.Connector.RfcSystemException' occured in sap.connector.rfc.dll
Additional Information: "Screen output without connection to user"
So, what does the error mean? why does the error only happen when calling BAPI_PO_RELEASE? Is there anyway i can work around this issues and call it via NCo 2.0 normally? Does it have anything to do with authorization or other security concerns? Because i can do it with other SAP customer also via NCo 2.0...
please advise. Thanks!
Regards,
Derek Tan

I'm not sure, but the error message sounds as if the function tries to bring up some SAPGUI screen. Perhaps this is just an error popup for this special user. You could try to temporarily enable SAPGUI using the USE_SAPGUI connection string parameter ("SAPGui" property in Destination). If SAPGUI is installed and my guess is right, you would see the screen.
