• What is the cause and solution for SAP error message CMD_BS_MAT_MKAL_API105 - BOM exists ?

  The SAP error message CMD_BS_MAT_MKAL_API105 indicates that a Bill of Materials (BOM) already exists for the material you are trying to create or modify. This error typically occurs when you attempt to create a new BOM for a material that already has an existing BOM in the system.
  Cause:
  
  Existing BOM: The primary cause of this error is that there is already a BOM defined for the specified material in the system.
  Incorrect Data Entry: You may be trying to create a BOM for a material that is not intended to have multiple BOMs or is already assigned to a different BOM.
  Material Status: The material might be in a status that does not allow for the creation of a new BOM.
  
  Solution:
  
  
  Check Existing BOM: 
  
  Use transaction code CS03 (Display BOM) to check if a BOM already exists for the material in question. If it does, you can either modify the existing BOM or delete it if it is no longer needed.
  
  
  
  Modify Existing BOM: 
  
  If the BOM exists and you need to make changes, you can use transaction code CS02 (Change BOM) to modify the existing BOM instead of creating a new one.
  
  
  
  Delete Existing BOM: 
  
  If the existing BOM is not needed, you can delete it using transaction code CS02 (Change BOM) and then select the delete option.
  
  
  
  Check Material Master Data: 
  
  Ensure that the material master data is correctly set up and that the material is intended to have a BOM. You can check this using transaction code MM03 (Display Material).
  
  
  
  Consult Documentation: 
  
  Review any relevant documentation or guidelines within your organization regarding BOM creation to ensure compliance with internal processes.
  
  
  
  Related Information:
  
  BOM Types: Understand the different types of BOMs (e.g., single-level, multi-level) and how they are used in your organization.
  Material Types: Different material types may have different rules regarding BOMs. Ensure that the material type you are working with allows for BOMs.
  Authorization: Ensure that you have the necessary authorizations to create or modify BOMs in the system.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues or provide additional guidance related to BOM management.
