MRP Exception Messages List for SAP S/4HANA - Understanding and Resolving Issues

This article discusses MRP Exception Messages, which can help analyze MRP results and take corrective actions. The list of exception messages includes stock shortages, procurement issues, scheduling errors, and missing BOMs, among others. Each message is grouped and explained, with examples not included in the article. The list is taken from transaction OMD3 and can be used to segregate MRP results and address the issues.

MRP (Material Requirements Planning) is a fundamental component of enterprise resource planning (ERP) systems, ensuring efficient material usage and production planning. However, deviations from the planned process can occur, leading to MRP exception messages. These messages serve as valuable tools for analyzing MRP results and identifying potential issues. In this article, we delve into the world of MRP exception messages, providing a comprehensive guide based on insights from transaction OMD3 and expert analysis.

One of the most common MRP exception messages is the stock shortage message (No. 96). This message alerts users when stock levels fall below safety stock levels. To address this issue, procurement proposals must be initiated to replenish the necessary materials.

Another critical message is the procurement proposal required message (No. 98). This message indicates that abnormalities have occurred during the materials planning process, necessitating manual intervention. Users must investigate the root cause of the problem and take appropriate actions to resolve the issue.

Maximum release quantity exceeded messages (No. 70) can also arise when release quantities as per the source of supply exceed the maximum allowed. To resolve this issue, users must either reduce the release quantity or obtain additional sources of supply.

Newly created order proposals can also generate exception messages. For instance, if an order proposal has an opening date in the past (No. 2), the user must change the opening date to a valid value. Similarly, if the start date is also in the past (No. 3), the user must reschedule the order proposal to meet the delivery requirements.

Scheduling-related messages (Nos. 61-64) can indicate inconsistencies in scheduling customizations or master data. Users must investigate and correct these issues to ensure accurate scheduling.

BOM (Bill of Materials)-related messages (Nos. 50-58) can indicate various issues, such as missing BOMs, unselected BOMs, or phantom assemblies that have not been exploded. Users must address these issues to ensure accurate material planning and production.

In conclusion, MRP exception messages are valuable tools for identifying and addressing issues in the materials planning process. By understanding the meaning and significance of each message, users can take corrective actions to maintain an efficient and effective ERP system.
