• What is the cause and solution for SAP error message C3021 - Altve BOM selection through multiple BOM table for BOM application & ?

  The SAP error message C3021 typically relates to issues with the Bill of Materials (BOM) selection process, particularly when there are multiple BOMs available for a given material. This error can occur in various scenarios, such as during production planning, material requirements planning, or when trying to create a production order.
  Cause:
  The error message C3021 indicates that the system is unable to determine which BOM to use because there are multiple BOMs available for the specified material. This can happen due to:
  
  Multiple BOMs Defined: There are multiple BOMs defined for the same material in the system, and the system cannot automatically select one.
  BOM Status: Some BOMs may be inactive or not valid for the current date or context.
  Configuration Issues: There may be issues with the configuration of the BOM selection criteria or the way the BOMs are set up in the system.
  
  Solution:
  To resolve the C3021 error, you can take the following steps:
  
  
  Check BOMs: Use transaction code CS03 (Display BOM) to check the BOMs defined for the material in question. Ensure that the correct BOM is active and valid for the required date.
  
  
  Specify BOM Selection Criteria: If multiple BOMs exist, you may need to specify selection criteria more explicitly. This can include:
  
  Using a specific plant or storage location.
  Specifying the BOM usage (e.g., production, engineering).
  Ensuring that the BOM is valid for the current date.
  
  
  
  Set Default BOM: If applicable, you can set a default BOM for the material in the material master (transaction code MM02) under the "BOM" view.
  
  
  Check BOM Status: Ensure that the BOMs are not marked as obsolete or inactive. You can do this in the BOM maintenance screen.
  
  
  Review Configuration: If you have access to configuration settings, review the settings related to BOM selection in the relevant customizing transactions (e.g., SPRO).
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on BOM selection and management.
