BPM Help / PO Entry

We are on Epicor 9.04 and we are wanting to remove the default GL account number under the revisions sheet of PO Entry to make the buyers enter a correct GL Acct. instead of just accepting the default when other is chosen on the lines sheet.

I have been able to get a BPM to bring up an informational message to remind them, but if they click on save it will still save the default GL account.

I need a way for TranGLC.GLAccount to be either blank or 000000-0000 .

 

I’m using PO.Update with the PODetail.CalcTranType field of the changed row is equal to the "PUR-UKN" expression to show an information message, but I need it to also blank or zero TranGLC.GLAccount.

 

I’ve tried several ways without success because I’m still new at BPM’s and I’m not a programmer.

 

Thanks,

Jim Moore
