• What is the cause and solution for SAP error message PLMDISCALC051 - BOM items that are marked as recursive were included ?

  The SAP error message PLMDISCALC051 indicates that there are items in a Bill of Materials (BOM) that are marked as recursive. This means that the BOM structure contains a loop where an item references itself directly or indirectly, which can lead to infinite loops during calculations or processing.
  Cause:
  
  Recursive BOM Structure: The most common cause of this error is that the BOM has been defined in such a way that one or more components reference themselves either directly or through a chain of other components.
  Incorrect BOM Configuration: Sometimes, the BOM might have been incorrectly configured, leading to unintended recursive relationships.
  Data Entry Errors: Manual data entry errors can also lead to recursive references being created in the BOM.
  
  Solution:
  
  
  Review BOM Structure: Check the BOM for the items that are causing the error. Look for any components that reference themselves or create a loop. You can do this by:
  
  Using transaction codes like CS03 (Display BOM) to view the BOM structure.
  Analyzing the component hierarchy to identify recursive references.
  
  
  
  Correct Recursive References: Once identified, you need to correct the BOM structure by:
  
  Removing or changing the recursive references.
  Ensuring that each component in the BOM is correctly defined and does not point back to itself.
  
  
  
  Use BOM Analysis Tools: SAP provides tools and reports that can help analyze BOM structures for issues. You can use these tools to identify and resolve recursive BOMs.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on BOM configuration and best practices to avoid recursive structures.
  
  
  Testing: After making changes, test the BOM calculations again to ensure that the error has been resolved.
  
  
  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 might address known issues or provide additional guidance on handling recursive BOMs.
  Training and Best Practices: 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 PLMDISCALC051 error and ensure that your BOMs are correctly structured without recursive references.
