I am enhancing the Goods Movement BDC program of MB1B.
When I am executing this BDC prog. directly by inputting the required data, its working well.
But, When I am running it in the <u><b>Debug mode</b></u> (to know the control flow), at the
<i><b>CALL TRANSACTION 'MB1B' USING bdcdata MODE 'N' UPDATE 'S' MESSAGES bdcmsgcoll</b></i>
statemrnt I am getting the SY-SUBRC 1,001 and the error message(in bdcmsgcoll) is,
<i><b>No batch input data for screen SAPMSSY3 121</b></i>
(When I hv checked this - SAPMSSY3 121 screen in SE80, Its a Debug screen!)
and the document is not creating and the stock is not updating!
1 - Why this is happening like this (coz of Synchronous mode?, actually, earlier with other prog. also happened like the same, but that time its test prog. I mean to say that, i guess this is a commmon problem with BDC! I am sorry if am wrong! )?
2- How to fix it?
