Displaying the MM and FI Document Number when Posting Invoices

In 4.5B, this PID is not available. When we upgrade to ERP6, users requested to have this function.

I searched the MIRO codes for some BADIs or enhancements, luckily found the code is using a PID IVFIDISPLAY to determine messages from message class (M8). Later on, I found below link from SAP help. I thougt this is really helpful if your sap system doesn't have document archive subsystem, because FI document numbers for PO invoices are more important than MM invoice document number.

Use

You can make settings so that when you post an incoming invoice, the system displays invoice document numbers generated in Materials Management, and the document number of the accounting document in Financial Accounting, and also the number of the invoice reduction document.

This applies to the following transactions:

• Enter Invoice (MIRO)

• Park Invoice (MIR7)

• Cancel Invoice (MR8M)

• Invoice Overview (MIR6)

• Evaluated Receipt Settlement (MRRL)

• Revaluation (MRNB)

• Invoicing Plan (MRIS)

• Invoice Verification in the Background (RMBABG00)
• In the status message, EDI invoices also receive the accounting document number

Activity

Activate display of the MM and FI document numbers using the user parameter IVFIDISPLAY, by entering the value X for the user. In the standard system, only the document number from Materials Management is displayed.
