Smart SAP Assistant

• What is the cause and solution for SAP error message /PLMI/GSS_R2B_SPLIT006 - Subordinate BOM &1 already exists; synchronization is not possible ?

  The SAP error message /PLMI/GSS_R2B_SPLIT006 indicates that there is an issue with the synchronization of a subordinate Bill of Materials (BOM) in the system. Specifically, it means that a subordinate BOM with the specified identifier already exists, and therefore, the system cannot synchronize the BOM as intended.
  Cause:
  
  Duplicate BOM Entries: The error typically arises when there are duplicate entries for a subordinate BOM in the system. This can happen due to incorrect data entry, data migration issues, or inconsistencies in the BOM structure.
  Incorrect Configuration: The configuration settings for BOMs may not be set up correctly, leading to conflicts when trying to synchronize BOMs.
  Data Integrity Issues: There may be underlying data integrity issues in the database that are causing the system to recognize the subordinate BOM as already existing.
  
  Solution:
  
  
  Check for Duplicates: 
  
  Use transaction codes like CS03 (Display BOM) to check if the subordinate BOM already exists. If it does, you may need to decide whether to delete the duplicate or modify it.
  
  
  
  Delete or Modify the Existing BOM: 
  
  If you find that the subordinate BOM is indeed a duplicate and not needed, you can delete it using transaction CS02 (Change BOM) or CS01 (Create BOM) to modify it as necessary.
  
  
  
  Review BOM Configuration: 
  
  Ensure that the configuration settings for BOMs are correct. This includes checking the BOM usage, status, and validity dates.
  
  
  
  Data Consistency Check: 
  
  Run consistency checks on the BOM data to identify any discrepancies. You can use transaction CSBI (BOM Information System) to analyze BOMs and their components.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or notes related to BOM synchronization issues for any specific guidance or patches that may address the problem.
  
  
  
  Contact SAP Support: 
  
  If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance. They may provide specific notes or patches that can resolve the issue.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01, CS02, CS03, and CSBI for managing BOMs.
  SAP Notes: Check the SAP Support Portal for any notes related to BOM synchronization issues, as there may be known issues or fixes available.
  BOM Structure: Understand the structure of BOMs in your organization, including how subordinate BOMs are defined and used.
