When transferring Item Receipts from Manage to Sage 50 Accounts, the Manage “PO Number” will be used as the Sage 50 Accounts “Order No.” It is not required to supply a “Vendor Invoice #” when creating Purchase Orders in Manage, nor is it required in Sage 50 Accounts. However, if a vendor invoice number is supplied when creating a Purchase Order in Manage, it will be applied to the “Ref” field in Sage 50 Accounts.
