• What is the cause and solution for SAP error message CC301 - Revision levels cannot be exploded down ?

  The SAP error message CC301, "Revision levels cannot be exploded down," typically occurs in the context of production planning and control, particularly when dealing with bill of materials (BOM) and routing in SAP. This error indicates that the system is unable to explode the BOM for a particular material due to issues related to revision levels.
  Cause:
  
  
  Revision Level Mismatch: The error often arises when there is a mismatch between the revision levels of the parent material and its components. If the parent material has a specific revision level, the components must also have the same or compatible revision levels to be exploded correctly.
  
  
  Inactive or Missing BOM: If the BOM for the specified revision level is inactive or does not exist, the system will not be able to explode it.
  
  
  Configuration Issues: There may be configuration settings in the system that prevent the explosion of BOMs with certain revision levels.
  
  
  Material Master Data Issues: The material master data for either the parent or the components may not be set up correctly, leading to this error.
  
  
  Solution:
  
  
  Check Revision Levels: Verify the revision levels of both the parent material and its components. Ensure that they match and are compatible.
  
  
  Review BOM Status: Check if the BOM for the specified revision level is active. You can do this by navigating to the BOM transaction (CS03) and checking the status of the BOM.
  
  
  Update BOM: If the BOM is inactive or missing, you may need to create or activate the BOM for the required revision level.
  
  
  Material Master Review: Ensure that the material master records for both the parent and components are correctly maintained, including the relevant revision levels.
  
  
  Configuration Settings: If necessary, review the configuration settings in the SAP system related to BOM and revision levels to ensure they are set up correctly.
