How to override manually entered PO charge account in BWC/Forms Using Account Gererator WF?

Hi All,

I have customized our PO Account Generator WF (POWFPOAG.wft) to generate PO charge and destination accounts in order to default accounts from either requester's default expense account or from projects. Things are working perfectly fine when WF is generating accounts.

But when a buyer is manually entering the charge account either using BWC or forms then we have put some checks in the WF so that code combination generation must abort when any of the entered segment is a part of the restricted list. I can see that WF is aborting successfully and not able to proceed further to generate other accounts. But the charge account which was entered manually is not getting override. Also, no error is coming  in BWC when saving that particular PO even though WF has aborted in back end.
