This function enables you to display a list of documents, their official numbers, and reference numbers. You can change any of the numbers individually by assigning SD billing or FI accounting document numbers manually to an official document number. You will need to do this if you print out your VAT invoice on the wrong prenumbered form, for example.

Furthermore, if you have not used the VAT invoice printing program to issue your SD documents or you have created your invoices directly in FI, you can assign an internal document number manually to an external official lot and document number.

You have maintained your lots and books in Customizing.

On the Display and Change Official Document Number (FI/SD) screen, fill out the Company code field. If you wish to select SD or FI documents by lots and books, fill out the SD documents tab or the FI documents tab.

Choose Display documents to generate a list of documents that contains the following information:

• Accounting document number
• Object key - a unique reference generated when an accounting document is posted via the Accounting interface
• Reference number - a combination of the official lot number and the official document number
• Official lot number
• Official document number

From this list, you can change the official document numbers as required. When you enter the official lot and document numbers, the system combines them into a new 15-digit reference number. This is then stored in the header data of the FI document. If you choose Further details, you can display information on a selected document and to make changes to that information.

When you have made all the necessary changes, choose Save.
