Display success notifications
In an iView created with VC, I use a BAPI to modify some data in an SAP table. Once succesfully done, I want the Iview to display a "Success message". the message doesn't need to be in a popup window. It could be just a usual portal notification, like the error notifications you get if a BAPI would be called with some incorrect input data (kind of status massage in the top left corner of the iview) or like the success notifications of the portal after saving a modified iview.
After some investigations, I know that error messages from BAPIs are displayed as portal notifications, if the BAPI provides an output table called Return, which has the same structure as the SAP structure BAPIRET2.
As in succesfull cases no messages are generated, the return structure is not filled and the portal doesn't show any success notification.
Any ideas to show "success" notifications in spite of that.
