Hello,

We have 2 separate policies setup for PO-based Invoices. 1 is for Direct PO's, and the other is for Indirect PO's. Most Indirect PO Invoices require the end user to add a Receipt and Receipt Attachment prior to submitting the Invoice. On the PO Receipt Form for Indirect PO's I have Required the Receipt Image ID (Attachment) field and am still able to submit an Invoice without the Attachment. The Audit Rules and PO Matching Rules don't go to the Receipt level either so I am not able to satisfy my requirements, any thoughts on how to achieve this? 

Thanks!
