By default, Perk only allows users to select purchase orders for the supplier selected as the invoice supplier.
However, you can choose to allow users to select POs from other suppliers. For example, your supplier may have multiple legal entities. An invoice may come from one legal entity, but the original PO was issued from another legal entity. You can handle these scenarios by allowing cross-supplier PO selection:
- Go to Settings > Supplier invoices > Invoice settings.
- In Enable purchase orders, select Allow cross-supplier PO selection.
- Click Save.
Purchase orders from suppliers other than the invoice supplier are displayed with the supplier ERP code and name in the Purchase order number field.
