MIRO | Post Vendor Invoice in SAP MM [TCode of the Day]

MIRO – Post Vendor Invoice

MIRO is the SAP transaction code used to post vendor invoices in Materials Management. It plays a key role in invoice verification, the final step in the P2P cycle.

TCode:

MIRO – Post Vendor Invoice

Module:

SAP MM & FI (Materials Management + Financial Accounting)

When to Use:

• After goods receipt (GR) has been posted via MIGO
• To enter vendor invoice data for payment
• To perform invoice verification against PO and GR

What Happens in MIRO?

• Select transaction type: Invoice
• Enter PO number – system pulls GR quantity and values
• Verify tax, price and quantity
• Post → creates accounting document in FI

Pro Tip:

Always check for GR/IR mismatches. If quantity or price differs between GR and invoice, MIRO may create a blocked invoice requiring release.

• ME23N – Display Purchase Order
• FB60 – Enter Vendor Invoice (FI only)

MIRO connects the logistics invoice with the financial posting, closing the loop in the SAP P2P process.
