LC237 - Details

• The SAP error message LC237 indicates that when multiple plants are selected in a Material Requirements Planning (MRP) run, you cannot specify an MRP controller. This is because the MRP controller is typically assigned to a specific plant, and when multiple plants are involved, the system cannot determine which MRP controller to use.
  
  Cause:
  The error occurs when:
  
  You are trying to execute an MRP run (e.g., MD01, MD02) for multiple plants at once.
  The system requires a single MRP controller to manage the planning process, but multiple plants do not have a single MRP controller assigned.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Run MRP for a Single Plant: Instead of selecting multiple plants, run the MRP for each plant individually. This way, the system can use the specific MRP controller assigned to that plant.
  
  
  Check MRP Controller Assignment: Ensure that each plant has an MRP controller assigned. You can check this in
