• What is the cause and solution for SAP error message /PLMI/MBOM_MAP_29263 - The BOM is now recursive (item &1 &2) ?

  The SAP error message /PLMI/MBOM_MAP_29263 indicates that there is a recursive Bill of Materials (BOM) issue in the system. This typically occurs when a BOM references itself directly or indirectly, leading to an infinite loop in the BOM structure. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Self-Referencing BOM: The BOM for a component includes itself as a sub-component.
  Indirect Recursion: A component in the BOM references another component that eventually leads back to the original component, creating a loop.
  Data Entry Errors: Incorrect data entry during BOM creation or modification can lead to recursive references.
  
  Solution:
  
  
  Review BOM Structure:
  
  Check the BOM for the item mentioned in the error message. Look for any self-references or indirect references that could create a loop.
  Use transaction codes like CS03 (Display BOM) to analyze the BOM structure.
  
  
  
  Correct the BOM:
  
  If you find a self-reference, remove it or adjust the BOM structure to eliminate the recursion.
  If there are indirect references, ensure that the components do not lead back to the original item.
  
  
  
  Use BOM Analysis Tools:
  
  Utilize SAP tools or reports that can help identify recursive BOMs. This may include custom reports or standard SAP reports that analyze BOM structures.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help notes related to BOM management for best practices and guidelines on structuring BOMs.
  
  
  
  Testing:
  
  After making changes, test the BOM to ensure that the error does not reoccur. You can do this by trying to create or modify a production order that uses the BOM.
  
  
  
  Related Information:
  
  BOM Types: Understand the different types of BOMs (e.g., single-level, multi-level) and how they should be structured.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on handling recursive BOMs.
  Training: Consider training for users involved in BOM creation and maintenance to prevent future occurrences of this error.
  
  By following these steps, you should be able to resolve the recursive BOM issue and prevent it from happening in the future.
