Smart SAP Assistant

• What is the cause and solution for SAP error message M_OBOM_WB_GNRL022 - Component &1 occurs multiple times in the structure; cannot fix ?

  The SAP error message M_OBOM_WB_GNRL022 indicates that a component (material) is being referenced multiple times in a Bill of Materials (BOM) structure, which is not allowed in certain contexts. This can occur when you are trying to create or modify a BOM and the system detects that the same component is listed more than once at the same level of the BOM hierarchy.
  Cause:
  
  Duplicate Entries: The most common cause is that the same material/component has been added multiple times to the BOM structure.
  Incorrect BOM Structure: The BOM may have been incorrectly structured, leading to the same component being referenced multiple times.
  Data Entry Errors: Manual data entry errors can lead to unintentional duplication of components.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the BOM Structure:
  
  Go to the BOM transaction (e.g., CS02 for changing BOM).
  Review the components listed in the BOM to identify any duplicates.
  
  
  
  Remove Duplicates:
  
  If you find that a component is listed more than once, remove the duplicate entries.
  Ensure that each component is only listed once at the same level of the BOM.
  
  
  
  Use the BOM Comparison Tool:
  
  If you are unsure about the structure, you can use the BOM comparison tool to identify differences and duplicates.
  
  
  
  Validate the BOM:
  
  After making changes, validate the BOM to ensure that it meets all requirements and does not contain any duplicates.
  
  
  
  Check for Related BOMs:
  
  If the component is part of multiple BOMs, ensure that the same component is not being referenced incorrectly across different BOMs.
  
  
  
  Related Information:
  
  BOM Types: Understand the different types of BOMs (e.g., single-level, multi-level) and how components are structured within them.
  SAP Documentation: Refer to SAP Help documentation for detailed information on BOM management and error handling.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM) for managing BOMs.
  User Exits and Enhancements: If you are working in a customized environment, check if there are any user exits or enhancements that might affect BOM processing.
  
  By following these steps, you should be able to resolve the M_OBOM_WB_GNRL022 error and ensure that your BOM is correctly structured without duplicate components.
