• What is the cause and solution for SAP error message MPE_CM_BOM036 - Changes cannot be saved as language key already exists ?

  The SAP error message MPE_CM_BOM036 indicates that there is an attempt to save changes to a Bill of Materials (BOM) in a specific language, but the system has detected that a record with the same language key already exists. This typically occurs when you are trying to create or modify a BOM in a language that already has an entry in the database.
  Cause:
  The primary cause of this error is that the system is designed to prevent duplicate entries for the same language key in the BOM data. When you attempt to save a BOM with a language that already has an existing entry, the system raises this error to maintain data integrity.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Entries: 
  
  Navigate to the BOM in question and check if there is already an entry for the language you are trying to save. You can do this by viewing the BOM in the relevant transaction (e.g., CS03 for display).
  
  
  
  Modify Existing Entry:
  
  If an entry already exists for the language, you may need to modify the existing BOM entry instead of trying to create a new one. Use the appropriate transaction (e.g., CS02 for change) to update the existing BOM.
  
  
  
  Delete Duplicate Entry:
  
  If the existing entry is incorrect or no longer needed, you can delete it (using CS02) before attempting to save your new changes.
  
  
  
  Use a Different Language:
  
  If it is appropriate for your business case, consider saving the BOM in a different language that does not have an existing entry.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for any specific guidelines related to BOM management in your version of SAP.
  
  
  
  Contact Support:

  Language Keys: Understand how language keys work in SAP and how they are used in BOMs and other master data.
  Data Integrity: Be aware of the importance of maintaining data integrity in your SAP system, especially when dealing with multilingual data.
