Information can be transferred between different companies using EDI. This enables a vendor to transfer invoice information electronically instead of in the form of a printed paper invoice. This has the following advantages:

• Fast data transfer
• Prevention of input errors when manually entering invoices

An IDoc is generated for each invoice. The system posts an invoice using the data in this IDoc. To do this, the invoice must be consistent and must not cause any error messages in the system.

You maintain the following settings for the IDoc interface:

When processing an IDoc invoice, the system proceeds as follows:

1. It determines the invoicing party.
2. It reads the data in the Customizing tables listed above.
3. It creates the invoice.

If it can, the system posts an invoice document for each IDoc.

If the EDI invoice contains variances, the invoice document is saved for background verification.

If the system cannot post the invoice, it gives the IDoc the appropriate error status. You must then process the IDoc manually, or transmit it again correctly.
