• What is the cause and solution for SAP error message CH084 - BOM "&" contains component "&" more than once with category "&" ?

  The SAP error message CH084 indicates that there is a problem with a Bill of Materials (BOM) where a specific component is listed more than once for a given BOM category. This can lead to inconsistencies in production planning and inventory management, as SAP expects each component in a BOM to be unique.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the same component has been added multiple times to the BOM for the same category.
  Incorrect BOM Configuration: The BOM may have been incorrectly configured, either during creation or modification.
  Data Migration Issues: If data has been migrated from another system or if there have been bulk uploads, duplicates may have been inadvertently created.
  
  Solution:
  
  
  Review the BOM: 
  
  Go to the BOM in question using transaction code CS03 (Display BOM).
  Check the list of components to identify any duplicates.
  
  
  
  Remove Duplicates:
  
  If duplicates are found, you can either delete the extra entries or consolidate them if they are meant to represent the same component.
  Use transaction code CS02 (Change BOM) to make the necessary adjustments.
  
  
  
  Check BOM Category:
  
  Ensure that the components are correctly categorized. If a component is meant to be used in multiple categories, it should be defined accordingly in the system.
  
  
  
  Validate BOM:
  
  After making changes, validate the BOM to ensure that it meets all requirements and does not contain any further errors.
  
  
  
  Consult Documentation: 
  
  Refer to SAP documentation or help resources for specific guidelines on BOM management and best practices.
  
  
  
  Related Information:
  
  BOM Categories: Understand the different BOM categories (e.g., production BOM, sales BOM, etc.) and how they affect component usage.
