ISSUE WITH F-02 BDC

After entering all the details, when i click 'SAVE' button to post the document,

a warning message appears. so i am required to press enter again to post the document. in short the BDC works fine in Foreground mode.

In my proj , we are creating documents via an interface, so SAP gets data from an interface application (Webmethods ) in this case and it calls a SAP RFC which in turn calls my F-02 BDC program. so this BDC must work in Background mode.

and in background i cannot press enter.

just to mention some things that i have already tried.

1. Have tried coding a forced "Enter" in the program.

Anyone who has faced similiar problem, pls advise.

Regards
