• What is the cause and solution for SAP error message LC237 - MRP controller cannot be specified if several plants are selected ?

  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 the material master data (transaction MM03) under the MRP views.
  
  
  Use a Group MRP Controller: If your business process allows, consider using a group MRP controller that can manage multiple plants. However, this may require configuration changes in your SAP system.
  
  
  Review MRP Settings: Check the MRP settings in the configuration (transaction SPRO) to ensure that they are set up correctly for your plants and MRP controllers.
  
  
  Consult Documentation: Refer to SAP documentation or help files for more detailed information on MRP controller settings and their implications.
  
  
  Related Information:
  
  MRP Controller: This is a key figure in the MRP process responsible for planning and managing materials for a specific plant.
  Material Master: The material master data contains information about materials, including MRP settings and controllers.
  MRP Transactions: Common transactions related to MRP include MD01 (Total Planning), MD02 (Single Item Planning), and MD03 (Single Item Multi-Level Planning).
  
  By following these steps, you should be able to resolve the LC237 error and successfully run your MRP processes in SAP.
