• What is the cause and solution for SAP error message COM_PRODUCT_BOM005 - Multi-level component lists are not allowed ?

  The SAP error message COM_PRODUCT_BOM005 indicates that multi-level component lists are not allowed in the context of the operation you are trying to perform. This typically occurs when you are working with Bill of Materials (BOM) in SAP and trying to create or manipulate a BOM that includes components with their own sub-components, which is not permitted in certain scenarios.
  Cause:
  
  Multi-Level BOM Structure: The error arises when you attempt to create or process a BOM that has multiple levels of components (i.e., a BOM that includes sub-components).
  Configuration Settings: The system may be configured to only allow single-level BOMs for specific operations or transactions.
  Transaction Context: The transaction you are using may not support multi-level BOMs, leading to this restriction.
  
  Solution:
  
  Check BOM Structure: Review the BOM you are trying to create or modify. Ensure that it adheres to the single-level BOM requirement if that is the case.
  Use Alternative Transactions: If you need to work with multi-level BOMs, consider using transactions that support them, such as creating a multi-level BOM in the appropriate context.
  Adjust Configuration: If your business process requires multi-level BOMs, you may need to adjust the configuration settings in SAP to allow for this. This may involve working with your SAP Basis or configuration team.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on BOM structures and the limitations of the transaction you are using.
  Error Handling: If you encounter this error during a specific process, consider implementing error handling in your workflow to manage such cases gracefully.
