How To Fix MF331 - Order & possibly contains recursive BOM components

SAP Error Message - Details

• Message type: E = Error

• Message class: MF - MPS planning and evaluation

• Message number: 331

• Message text: Order & possibly contains recursive BOM components

What causes this issue?

The order contains component reservations that could have a higher
<DS:GLOS.low-level_code>low-level code</> than that of the order
material.
To avoid an endless loop the requirement for this component is not
included.

• What is the cause and solution for SAP error message MF331 - Order & possibly contains recursive BOM components ?

  The SAP error message MF331 indicates that there is a problem with a Bill of Materials (BOM) in the context of production order processing. Specifically, it suggests that the system has detected a recursive BOM component, which means that a component in the BOM references itself either directly or indirectly, leading to an infinite loop.
  Cause:
  
  
  Recursive BOM Structure: The most common cause of this error is that the BOM structure is incorrectly defined, where a component is linked back to itself. This can happen if:
  
  A component is mistakenly included in its own BOM.
  There are circular references in the BOM hierarchy.
  
  
  
  Incorrect Configuration: Sometimes, the configuration of the BOM or the material master data may not be set up correctly, leading to recursive relationships.
  
  
  Data Entry Errors: Manual data entry errors during BOM creation or modification can also lead to this issue.
  
  
  Solution:
  
  
  Review the BOM: 
  
  Go to the BOM in question and check the components listed. Look for any components that reference themselves or create a circular reference.
  Use transaction code CS03 (Display BOM) to view the BOM structure.
  
  
  
  Correct the BOM Structure:
  
  If you find a recursive reference, you will need to remove or correct it. This may involve editing the BOM using transaction code CS02 (Change BOM).
  Ensure that the components are correctly defined and do not reference themselves.
  
  
  
  Check for Indirect References: 
  
  Sometimes, the recursion may not be direct. Check if any of the components in the BOM reference other components that eventually lead back to the original component.
  
  
  
  Use BOM Reports: 
  
  Utilize standard SAP reports or tools to analyze BOM structures for potential issues. Reports like CS15 (BOM Comparison) can help identify discrepancies.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help resources for guidelines on proper BOM structure and management.
  
  
  
  Testing: 
  
  After making changes, test the production order creation process again to ensure that the error has been resolved.

  Transaction Codes:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  CS15: BOM Comparison
  CS12: Multilevel BOM
  
  
  
  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 specific issues related to BOMs and recursive components.
  
  
  Training and Documentation: Consider training for users involved in BOM management to minimize data entry errors and improve understanding of BOM structures.
  
  
  By following these steps, you should be able to identify and resolve the MF331 error related to recursive BOM components in SAP.
