Hi
My modulepool program calls the transaction 'FBZ4' to post a document.I hv done a BDC recording for 'FBZ4'. When the call transaction is executed, it will stop at the Overview screen where v'l hv the items displayed with the amount.If the user wants to post it he can post it or else he can come out of the screen from the overview screen.
Now I want to put validation at this overview screen before posting.I hv a field 'Available Balance' on my modulepool selection screen, if the available balance is less than the amount displayed in the overview screen it shd give an error msg.
I tried some logic after call transaction but it is not workin out....
when v click on 'POST' in the overview screen the check shd happen. can anyone plz help on this...
