Assigning GUI Numbers

The system does not assign a GUI number until you run the GUI/VAT Creation from Multi-AR (R75T004S) or GUI/VAT Creation from Multi-SO (R75T004O) program in final mode. The system automatically assigns the next available GUI number from a batch of GUI numbers if you set up the system to do so.

When you run the GUI/VAT Creation From Multi-AR program, the system also updates the GUI/VAT number in the URRF field of the F03B11 table.

See Setting Up GUI Numbering.

You can use the Get GUI Number option in the GUI/VAT Transactions Revision program to manually assign a number. You can access only a number that is set up for the declaration site and period.

You can use the GUI number during receipt and draft processing to match customer payments to invoices. The GUI number is also displayed in the Customer Ledger Inquiry program, on accounts receivable statements, and on collections and aging reports.

Note: GUI numbers are assigned at the pay item level. Therefore, you cannot summarize or consolidate pay items.

Changes to and deletions of invoices and their associated GUI information are not supported. If you change or delete an invoice, you must manually update the GUI/VAT Transaction Header table (F75T004) and the GUI/VAT Transaction Detail table (F75T005) to ensure integrity between the Customer Ledger table (F03B11) and the F76T004 and F75T005 tables.
