• What is the cause and solution for SAP error message CM_MRP_BUFFER005 - Dynamic horizon &1 is not allowed ?

  The SAP error message CM_MRP_BUFFER005, which states "Dynamic horizon &1 is not allowed," typically occurs in the context of Material Requirements Planning (MRP) when there is an issue with the configuration of the dynamic horizon settings in the MRP parameters.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Invalid Dynamic Horizon Setting: The dynamic horizon value specified in the MRP settings is not valid. This could be due to it being set to a negative value, zero, or a value that exceeds the maximum allowed limit.
  
  
  Configuration Issues: The MRP configuration may not be set up correctly, leading to the system rejecting the dynamic horizon value.
  
  
  Master Data Issues: The material master data may have incorrect settings that conflict with the dynamic horizon configuration.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check MRP Parameters:
  
  Go to the MRP settings in the configuration (Transaction code: OMD0 or OMD1).
  Verify the dynamic horizon settings and ensure that they are set to a valid value. The dynamic horizon should be a positive integer that is within the acceptable range.
  
  
  
  Review Material Master Data:
  
  Check the material master data for the affected materials (Transaction code: MM03).
  Ensure that the MRP type and other relevant fields are correctly configured.
  
  
  
  Adjust Dynamic Horizon:
  
  If the dynamic horizon is set incorrectly, adjust it to a valid value. You can do this in the MRP area settings or in the MRP profile.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help files for specific details on the dynamic horizon settings and their implications.
  
  
  
  Test Changes:
  
  After making changes, run the MRP process again to see if the error persists.
  
  
  
  Related Information:
  
  MRP Types: Understand the different MRP types (e.g., MRP, MPS) and how they interact with dynamic horizon settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  Transaction Codes: Familiarize yourself with transaction codes related to MRP configuration and material master maintenance (e.g., MD01 for MRP run, MM02 for material master changes).
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in MRP processes.
