An invoice contains various information, such as:

• Who issued the invoice?
• Which transaction does the invoice refer to?
• How much tax do you have to pay?

If the invoice refers to a particular transaction, the system will automatically retrieve information pertaining to the transaction and propose values on the screen for you to check. Information that can be retrieved includes:

• Terms of payment
• Quantities to be invoiced
• The amounts the system expects per item

If the vendor's invoice contains different details, you can overwrite the data proposed. The system checks whether your entries are permissible and will display a warning or other message if anything is incorrect.

The information known to the SAP system and the fields in which you can enter new information from the invoice are located on different screens.
