select Multiple Order Lines in Import scenario using ADD PO Lines Action on Purchase Receipts

Hi Experts,

I'm currently working on an import scenario where I need to select multiple order lines using the Add PO Line action on the Purchase Receipts Screen.

I came across the following forum post which addresses a similar issue:
[Import Scenario - Purchase Receipts - ADD PO LINE button not adding PO Line 2](Forum link)

However, the solution provided seems to work only for single transaction orders. When dealing with multiple line orders, it fails to function correctly. Could someone please assist me in resolving this issue?

Any assistance on this matter would be greatly appreciated.

Thank you.
