Business Need: When creating a Purchase Order (PO) from a Sales Order (SO), the system currently carries over nested line items regardless of whether they are associated with the selected supplier. This requires users to manually review and remove unrelated line items, which increases the risk of errors and adds unnecessary processing time.

Current Behavior:

During PO creation from an SO, nested line items are carried over to the PO even when they are not assigned to the selected supplier.

Users must manually identify and remove line items that do not belong to the supplier chosen for the PO.

Requested Enhancement: Provide an option to automatically filter and exclude nested line items that are not associated with the selected supplier when generating a PO from an SO.
