Issues Processing Vendor Payments?

On several occasions I have had customers ask why they cannot process a check for a vendor. I am sure that there are many reasons, but more often than not, the A/P Invoice that they are trying to process does not have Pay To assigned to it on the Logistics Tab of the order. The reason why the order does not have a pay to assigned to it is normally because they have not defined a default pay to address in the Business Partner Master (under the address tab).

To process the payment for an AP Invoice that is "stuck", just go to the order and select the address to pay to from the list of addresses in the drop down control beside the address block and SAP Business One will populate it on the order (then click Update). To prevent this situation from occurring again, just set a default address for the customer in the Business Partner Master.
