Best practices for managing purchase orders in SAP Business One

For those using SAP Business One for procurement — what’s your workflow for managing POs from creation to goods receipt?

We currently handle:
1. PO creation with multi-currency support
2. Goods receipt matching
3. AP invoice reconciliation

Main pain points we face:
– Partial deliveries across multiple shipments
– Currency fluctuation between PO and GR dates
– Vendor credit note handling

Any tips or best practices from experienced SAP B1 users would be greatly appreciated.
