• What is the cause and solution for SAP error message 88857 - BOM component &1 is recursive; recursivity is not allowed ?

  The SAP error message "88857 BOM component &1 is recursive; recursivity is not allowed" indicates that there is a recursive relationship in the Bill of Materials (BOM) definition. This means that a component in the BOM is referencing itself directly or indirectly, which is not allowed in SAP.
  Cause:
  The error occurs when:
  
  A component in the BOM is defined in such a way that it refers back to itself. For example, if Component A includes Component B, and Component B includes Component A, this creates a recursive loop.
  This can also happen if a component is defined in a way that it indirectly leads back to itself through other components.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the BOM Structure:
  
  Check the BOM for the material in question and identify the components listed.
  Look for any components that may be referencing each other in a circular manner.
  
  
  
  Modify the BOM:
  
  Remove or change the recursive reference. Ensure that no component in the BOM points back to itself or creates a loop through other components.
  If necessary, redesign the BOM structure to eliminate the recursion.
  
  
  
  Use the BOM Display Transaction:
  
  Use transaction code CS03 (Display BOM) to view the BOM and analyze the components.
  You can also use CS02 (Change BOM) to make necessary adjustments.
  
  
  
  Check for Alternative BOMs:
  
  If the recursive component is necessary for some reason, consider using alternative BOMs or variants that do not create recursion.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for further guidance on BOM structures and best practices.
  
  
  
  Related Information:
  
  BOM (Bill of Materials): A BOM is a comprehensive list of raw materials, components, and assemblies required to manufacture a product.
  Recursion in BOM: Recursion in BOMs can lead to infinite loops in calculations and is therefore restricted in SAP.
  SAP Notes: Check SAP Notes for any specific patches or updates related to BOM handling that may address similar issues.
  
  By following these steps, you should be able to identify and resolve the recursive BOM component issue in SAP.
