• What is the cause and solution for SAP error message MW654 - Model allocation rules cannot contain plants. Please delete ?

  The SAP error message MW654 ("Model allocation rules cannot contain plants. Please delete.") typically occurs in the context of model allocation in SAP, particularly when dealing with the allocation of materials or products to different plants. This error indicates that the allocation rules you are trying to set up or modify include specific plants, which is not allowed in the context of model allocation.
  Cause:
  The primary cause of this error is that the model allocation rules are designed to be plant-independent. When you attempt to include specific plants in the allocation rules, SAP generates this error because it violates the system's constraints regarding model allocation.
  Solution:
  To resolve this error, you need to modify the allocation rules to ensure that they do not include any specific plant assignments. Here are the steps you can take:
  
  
  Access the Allocation Rules:
  
  Go to the relevant transaction in SAP where you manage model allocation rules (e.g., transaction code MM02 for material master or MC84 for model allocation).
  
  
  
  Review the Allocation Rules:
  
  Check the existing allocation rules for any entries that specify plants. 
  
  
  
  Delete Plant-Specific Entries:
  
  Remove any plant-specific entries from the allocation rules. Ensure that the rules are set up to be general and applicable across all plants.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the changes to the allocation rules.
  
  
  
  Test the Changes:
  
  Perform a test to ensure that the allocation rules are now functioning correctly without the error message.
