Frequent issues on MD04 (Stock/Requirements list )

The most used transaction in PP-MRP is the stock/requirements list.

Issues from many different application areas are reflected in transaction MD04, since this transactio reads data from many different tables.

On this document you will find the most frequent issues observed on transaction MD04.

1 - An MRP element is displayed on transaction MD04, however, it does not affect the available quantity, that means, it is not MRP relevant.

This issue can happen for many different planning elements, from sales orders to dependent requirements and there are many different causes for this issue.

On the following note you will find a detailed explanation for the possible causes for each different planning element:
