• What is the cause and solution for SAP error message MO050 - System language is & but maintenance language is & ?

  The SAP error message MO050 indicates a mismatch between the system language and the maintenance language in the SAP system. This typically occurs when a user tries to access a transaction or perform an operation that requires a specific language setting, but the system is configured with a different language.
  Cause:
  
  Language Mismatch: The error arises when the system language (the language in which the SAP GUI is displayed) does not match the maintenance language (the language set for the transaction or data being accessed).

  Check User Profile:

  Check the "Defaults" tab for the "Logon Language" setting. Ensure it matches the required maintenance language.
  
  
  
  Change Logon Language:
  
  If the logon language is incorrect, you can change it to the required language. Log out and log back in with the correct language.
  
  
  
  Transaction-Specific Language:
