Purchase invoice matching by packing slip

To support third party Accounts Payable (AP) automation solutions, the packing slip number can now be added to the existing PurchaseInvoice BDE. During purchase invoice processing, this packing slip number is used to correctly match the related receipts.

Note: A BDE (Business Data Entity) is an XML message, like a BOD (Business Object Document). However, instead of using ION as a means of transport from one package to another, a BDE uses web services for communication.
