Description of problem:

PO line inquiry forms document handling is inconsistent in display and functionality.

Open Purchase Order Lines inquiry:
The attachment form header correctly shows that the user is looking at the selected PO line, and attachments correctly open relating to the selected PO line.
The user can only view attachments, they cannot edit existing or add new attachments, for the selected PO line.

Backorder Purchase Lines inquiry:
The attachment form header incorrectly shows that the user is looking at the vendor attachments for the vendor for the selected PO line, but attachments actually correctly open for the selected PO line.
The user has full add, edit and view functionality for attachments to the selected PO line.

Actual Result:
In open purchase order lines, we cannot edit or create new attachments and in Backorder lines Showing as ‘’attachments for vendor account: 1001’’. Expected is’’ attachments for purchase order :000100, D0001’’


Expected Result:
In open purchase order lines, we should be able edit and create new attachments and in Backorder lines should Show as ‘’attachments for purchase order :000100, D0001’’ instead of ‘’attachments for vendor account: 1001’’.
