• What is the cause and solution for SAP error message WB2_ASGT105 - Material &1 is maintained more than once as component of material &2. ?

  The SAP error message WB2_ASGT105 indicates that a specific material (denoted as &1) is assigned multiple times as a component of another material (denoted as &2) in the Bill of Materials (BOM). This situation can lead to confusion and inconsistencies in production planning and inventory management.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the same material has been added multiple times to the BOM for a particular finished product or assembly.
  Incorrect BOM Configuration: There may be an error in how the BOM is configured, leading to the same component being listed more than once.
  Data Migration Issues: If data was migrated from another system or if there were manual entries, duplicates may have been inadvertently created.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the BOM:
  
  Go to the BOM transaction (e.g., CS03 to display BOM).
  Enter the material number for &2 and check the components listed.
  Look for the duplicate entry of &1.
  
  
  
  Remove Duplicates:
  
  If you find that &1 is listed more than once, you need to remove the duplicate entry.
  You can do this by using the BOM change transaction (CS02) to edit the BOM and delete the duplicate line.
  
  
  
  Validate BOM:
  
  After making changes, validate the BOM to ensure that it is correctly configured and does not contain any duplicates.
  
  
  
  Check for Related BOMs:
  
  If the material is used in multiple BOMs, check other BOMs to ensure that the same issue does not exist elsewhere.
  
  
  
  Transport Changes:
  
  If you are working in a development environment, ensure that the changes are transported to the production environment if necessary.
  
  
  
  Related Information:
  
  BOM Structure: Understanding the structure of BOMs in SAP is crucial. Each BOM can have multiple components, and each component can have specific quantities and other attributes.
  SAP Documentation: Refer to SAP Help documentation for detailed information on BOM management and error handling.
  Transaction Codes:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  CS11: Display BOM for a material
  
  
  User Authorizations: Ensure that you have the necessary authorizations to make changes to BOMs in the system.
  
  By following these steps, you should be able to resolve the WB2_ASGT105 error and ensure that your BOMs are correctly configured without duplicate components.
