Hi,
Part of the design of Purchase Orders for Adagio was maintaining backwards compatibility of DOS Inventory Receipts. In DOS IR, you had to have at least a 6 digit PO number.
You should be able to create a mask to report only a 4 digit code if that is what you are looking for on a report.
Unfortunately for now, you will still need to enter a 6 digit PO number to search or find a PO number, including leading zeros.
Regards,
Brian
