• What is the cause and solution for SAP error message MDG_BS_MAT_MKAL_API105 - BOM exists ?

  The SAP error message MDG_BS_MAT_MKAL_API105 indicates that a Bill of Materials (BOM) already exists for the material you are trying to create or modify in the Master Data Governance (MDG) system. This error typically arises when there is an attempt to create a new material or update an existing one, but the system detects that a BOM is already associated with that material.
  Cause:
  
  Existing BOM: The primary cause of this error is that the material you are trying to create or modify already has an associated BOM in the system.
  Data Inconsistency: There may be inconsistencies in the data being processed, leading the system to believe that a BOM exists when it should not.
  Incorrect Input: The input data might not be correctly formatted or might be missing required fields, leading to the system's inability to process the request.
  
  Solution:
  
  
  Check Existing BOMs: 
  
  Use transaction codes like CS03 (Display BOM) to check if a BOM already exists for the material in question. If it does, you may need to modify or delete the existing BOM instead of trying to create a new one.
  
  
  
  Modify Existing BOM: 
  
  If you need to make changes to the BOM, consider using the appropriate transaction (e.g., CS02 for changing a BOM) instead of creating a new one.
  
  
  
  Review Input Data: 
  
  Ensure that the data you are trying to input is correct and complete. Check for any missing fields or incorrect values that might be causing the error.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help files related to BOMs and MDG to ensure you are following the correct procedures.
