• What is the cause and solution for SAP error message GG170 - Do not enter the logon language ?

  The SAP error message GG170, which states "Do not enter the logon language," typically occurs when a user attempts to log into the SAP system and specifies a logon language in a way that is not permitted by the system configuration.
  Cause:
  
  Logon Language Specification: The error usually arises when the logon language is explicitly entered in a way that the system does not accept. This can happen if the user tries to enter a language code that is not supported or if the system is configured to not allow manual entry of the logon language.
  System Configuration: The SAP system may be configured to use a default logon language, and manual entry is restricted to prevent inconsistencies or errors.
  
  Solution:
  
  Use Default Logon Language: Instead of entering a logon language manually, simply leave the logon language field blank. The system will then use the default logon language configured for your user profile or the system.
  Check User Profile: Ensure that your user profile is set up correctly with a valid default logon language. You can check this in the user maintenance transaction (SU01) by looking at the "Defaults" tab.
  Consult with Administrator: If you continue to experience issues, it may be helpful to consult with your SAP system administrator. They can check the system settings and user profiles to ensure everything is configured correctly.
