Creating Auto-create PO from Auto create Document Note display Issue

Hi All,

We are facing issue in Our UAT Instance(R12.2.4) where we created new Responsibility like " Global Purchasing Buyer" and we've included around 75 OU through HRMS Security profile.
Purpose behind this Buyer can auto create PO for any OU Based on Requisition.so that he/she don't need to switch responsibility.

Issue :  When we create PO from Auto-create functionality Generally it display Note with PO Number and once we click Ok it open PO from. In our case that Note is not populate and it directly opening PO in Purchase order form, User requested to display Note.

If anyone face this issue earlier can share some pointers for resolution on this will be
