3778664 - Error Message When Starting MRP-run in MD03

Running MD03 for a specific material and MRP Area combination there is an error message that states that the plant does not exist. After the D&S switch was turned on; issue appears when an inherited supplier relationship is active on the FE/MRP Area that wants to order and the material has special procurement 40. The standard SAP code doesn’t find the plant, so MRP cannot proceed. 

When there is an inherited relationship and the material is on special procurement 40, the standard SAP code somehow doesn't find the plant and it's not possible to start the MRP for this material. All MD were checked and the plant is assigned to the material as well as the MRP Area.
