Understanding Invoices with Legal Numbers
When you enter an invoice, the system assigns an internal number and a legal number to the invoice. Legal numbers can be generated automatically or manually.
Localized invoice information is stored in these tables:
Invoice Total - ARG (F76A09)
Taxes - Tax Amount by Invoice Suffix (F76A19)
The legal number is also stored in the Reference field (VR01) of the Customer Ledger table (F03B11).
Note:
After invoices have been entered, they cannot be voided unless they are posted and reclassified.
For self-withholding to occur, you must run the Self Withholding per Receipt program (R76A96).
