If you have EDI invoicing set up with a vendor, there needs to be a match point between the purchase order line (POL) and the invoice line in Alma. The formatting of this number depends on the vendor, but it will always be placed in the "Vendor Information" section of the POL.
Two pieces of information are required:
The vendor title number is placed in the "Vendor reference number" field.
The Agent’s unique subscription reference number (SNA) is selected in the "Vendor reference number type" field.
