Explain a real-time SAP MM issue you solved?

Answer 1

In one of my projects, we faced an issue where Goods Receipt (GR) was posted successfully, but the vendor invoice could not be posted, and the GR/IR clearing account showed a mismatch.

🔍 Problem Description

A Purchase Order was created correctly.

Goods Receipt was posted, and stock was updated.

During Invoice Receipt (MIRO), the system showed a price difference error, and the invoice could not be posted.

The GR/IR account was not clearing, causing problems in month-end closing.

🛠 Root Cause Analysis

After analyzing the issue, I found:

The PO price and invoice price were different.

The tolerance limits for price variance were not maintained properly.

The valuation class was linked to an incorrect G/L account.

🧩 Solution Implemented

Checked the PO pricing conditions and compared them with the invoice.

Verified tolerance limits in configuration and updated them as per business requirement.

Corrected the automatic account determination for the valuation class.

Reposted the invoice using MIRO, and the system accepted it successfully.

The GR/IR account cleared automatically after posting.

🎯 Result

Invoice was posted without errors.

GR/IR account was cleared correctly.

Month-end closing issues were resolved.

The business process continued smoothly without delays.
