• What is the cause and solution for SAP error message MD06104 - Error in Customizing. Plant &2 is assigned to several MRP areas ?

  The SAP error message MD06104 indicates that there is an issue with the assignment of a plant to multiple MRP (Material Requirements Planning) areas. This error typically arises when a plant is assigned to more than one MRP area, which can lead to conflicts in the MRP configuration.
  Cause:
  The primary cause of the MD06104 error is that the same plant is assigned to multiple MRP areas in the system. In SAP, each MRP area is intended to represent a specific area of planning within a plant, and a plant should only be assigned to one MRP area to avoid confusion in material planning and inventory management.
  Solution:
  To resolve the MD06104 error, you need to check the MRP area assignments for the affected plant and make the necessary adjustments. Here are the steps to do this:
  
  
  Check MRP Area Assignments:
  
  Go to the transaction code OMD1 (or navigate through the menu: Logistics -> Production -> MRP -> MRP Area -> Define MRP Areas).
  Look for the plant in question and review the MRP area assignments.
  
  
  
  Remove Duplicate Assignments:
  
  If you find that the plant is assigned to multiple MRP areas, you will need to decide which MRP area should be retained and remove the others.
  You can do this by selecting the MRP area you want to delete and using the delete option.
  
  
  
  Adjust MRP Area Configuration:
  
  If necessary, you may need to reconfigure the MRP areas to ensure that each plant is only assigned to one MRP area.
  Ensure that the MRP area settings align with your business processes and planning requirements.
  
  
  
  Test the Configuration:
  
  After making the changes, run a test MRP run to ensure that the error no longer occurs and that the planning process works as expected.
