• What is the cause and solution for SAP error message TL122 - 'HEADER' file not found in the language directory ?

  The SAP error message TL122 indicates that the system is unable to find the 'HEADER' file in the specified language directory. This typically occurs during the translation process or when the system is trying to access language-specific files that are necessary for displaying text in the user interface.
  Cause:
  
  Missing Language Files: The required language files for the specified language are not present in the SAP system.

  Solution:
  
  
  Check Language Installation:
  
  Ensure that the required language is installed in the SAP system. You can check this in the SAP GUI by navigating to System -> Status and looking for the installed languages.
