We are having a problem in our MD04 screen where the MRP element "Ord.DS" which is the requirement for a schedule line on a stock transport order, and the MRP element "Delvry" which is the delivery created to ship the product on the stock transport order are showing up as requirements on MD04 at the same time. MRP is seeing this as two requirements instead of one and creating a planned order to replace the stock. I know how to create and change the display and selection filters, but I don't think I should have to do that. Anyone know of some configuration I have missed somewhere?
Although this post is old, it is still relevant. The issue is most likely due to CO09 being out of synch with the MRP elements in MD04. Periodically, you must run SDRQCR21 (SAP note 1166713) standard SAP program to clean up deliveries. This should be run at a convenient time as I recall, but certainly not at peak hours.
Hope this helps someone in the future.
