What is the issue?
Purchase Documents ( Purchase Requisition/ Purchase Order / Goods Receipt) are not visible under the Document tab in AP Edge view.
Root Cause:
Purchasing document search enhancements in Edge.
Check this:
Logged in users have any kind of pending action or users performed any action on the respective document.
Resolution:
If an user selects the Your requisitions / Orders: It narrows results down to only documents on which you are the Owner (Logged in user) and IF you select All requisitions/ Orders: It shows all documents on which you are present in the Actions table (logged-in user has taken some action).
If an user wants to have access to all documents for an organization, He will need to have the Professional User rights.
