• What is the cause and solution for SAP error message CM_MRP_BUFFER008 - mismatch iv_dynamic_horizon_code and is_dynamic_horizon_definition ?

  The SAP error message CM_MRP_BUFFER008 indicates a mismatch between the iv_dynamic_horizon_code and the is_dynamic_horizon_definition parameters in the context of Material Requirements Planning (MRP). This error typically arises when there is a discrepancy in the configuration or data related to dynamic horizon settings in the MRP process.
  Cause:
  
  Configuration Issues: The dynamic horizon settings may not be properly configured in the system. This could involve incorrect settings in the MRP configuration or missing definitions.
  Data Inconsistency: There may be inconsistencies in the data being passed to the MRP function module, leading to a mismatch between the expected and actual values.
  Custom Development: If there are custom developments or enhancements in the MRP process, they might not be handling the dynamic horizon parameters correctly.
  
  Solution:
  
  
  Check Configuration:
  
  Review the MRP configuration settings in the SAP system. Ensure that the dynamic horizon settings are correctly defined and aligned with the expected values.
  Navigate to the relevant configuration transaction (e.g., SPRO) and check the settings under MRP.
  
  
  
  Validate Data:
  
  Ensure that the data being passed to the MRP function module is correct. Check the values of iv_dynamic_horizon_code and is_dynamic_horizon_definition to ensure they match the expected definitions.
  You may need to debug the MRP process to see what values are being passed and where the mismatch occurs.
  
  
  
  Review Custom Code:
  
  If there are any custom developments related to MRP, review the code to ensure that it correctly handles the dynamic horizon parameters.
  Look for any logic that might be altering the values of iv_dynamic_horizon_code or is_dynamic_horizon_definition.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to MRP and dynamic horizon settings for any specific guidance or known issues.
  
  
  
  SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance. They may provide insights based on the specific version of SAP you are using.
