Merge Purchase Orders

Combines two purchase orders in Editing status into a single PO. Line items from the second selection are merged into the first: matching products have quantities and shipment/receipt counters summed; new products are copied over. The second purchase order is permanently deleted after a successful merge.

• Select the target PO in the first dropdown — this PO is kept.
• Select the source PO in the second dropdown — its lines are absorbed, then it is removed.
• Warning — this cannot be restored!
