• What is the cause and solution for SAP error message /SAPAPO/CURTO081 - Recursion: Header material &1 is also a component ?

  The SAP error message /SAPAPO/CURTO081 Recursion: Header material &1 is also a component typically occurs in the context of SAP Advanced Planning and Optimization (APO) when there is a recursive relationship in the bill of materials (BOM) or product structure. This means that a material is defined as both a header material and a component within the same BOM, leading to a circular reference that the system cannot resolve.
  Cause:
  
  Circular Reference: The most common cause of this error is that the material (header) is also listed as one of its own components in the BOM. This creates a loop that the system cannot process.
  Incorrect BOM Configuration: There may be an error in how the BOM is configured, where the same material is mistakenly included in its own structure.
  Data Migration Issues: If data has been migrated from another system or if there have been recent changes to the BOM, it may have introduced inconsistencies.
  
  Solution:
  
  Review BOM Configuration: Check the BOM for the material in question. Ensure that the material is not listed as a component of itself. If it is, remove it from the component list.
  Check for Recursive Structures: Look for any other materials that may have similar recursive relationships. Ensure that no other materials are defined in a way that creates a loop.
  Use Transaction Codes: You can use transaction codes like CS03 (Display BOM) to view the BOM and make necessary adjustments.
  Data Validation: If the issue arose after a data migration, validate the data to ensure that there are no other inconsistencies or errors.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on BOM configuration and best practices.
  
  Related Information:
  
  BOM Structure: Understanding how BOMs are structured in SAP APO is crucial. Each material can have multiple components, but it should not reference itself.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Testing Changes: After making changes to the BOM, test the configuration to ensure that the error does not reoccur.
  Support: If the issue persists, consider reaching out to SAP support for further assistance, especially if it involves complex configurations or custom developments.
  
  By addressing the recursive relationship in the BOM, you should be able to resolve the error and ensure that your material planning processes function correctly.
