• What is the cause and solution for SAP error message W/143 - Logon language & is used as the language ID ?

  Certainly! Here's a detailed explanation regarding the SAP message W/143 Logon language & is used as the language ID:
  
  SAP Message:
  W/143 Logon language & is used as the language ID
  
  Cause:
  This warning message occurs during the SAP logon process when the system detects that the logon language parameter is either missing, empty, or incorrectly specified. The placeholder & in the message is replaced by the actual language ID used during logon.
  
  The system expects a valid language key (e.g., EN, DE, FR) to be provided during logon.
  If the language ID is not provided or is invalid, SAP defaults to a certain language (usually the system default language).
  This message is a warning indicating that the language ID used might not be explicitly set or recognized, and the system is using the provided or default language ID.
  
  
  Explanation:
  
  The logon language is important because it determines the language in which the SAP GUI and messages are displayed.
  If the language ID is missing or invalid, SAP will still allow logon but warns that the language used might not be as expected.
  This can happen if the SAP GUI logon parameters are not set correctly or if the user profile or system settings do not specify a default language.
  
  
  Solution:
  
  
  Check SAP GUI Logon Settings:
  
  Ensure that the language field in the SAP Logon screen is correctly filled with a valid language key (e.g., EN for English).
  If the field is left blank, the system might use the default language, triggering the warning.
  
  
  
  User Master Record:
  
  Verify the user master record in transaction SU01.
  Check the "Logon Data" tab and ensure the default logon language is set correctly.
  
  
  
  System Default Language:
  
  Check the system default language settings.
  If necessary, set or correct the default language in system profile parameters or during system installation.
  
  
  
  SAP GUI Version:
  
  Sometimes older SAP GUI versions or corrupted installations can cause issues with language settings.
  Update or reinstall SAP GUI if necessary.
  
  
  
  Suppress Warning (if acceptable):
  
  Since this is a warning, it does not prevent logon.
  If the language setting is intentional and the warning is not critical, it can be ignored.
  
  
  
  
  Additional Information:
  
  Message Class: W (Warning)
  Message Number: 143
  Transaction: Occurs during logon or in user-related transactions.
  Related Transactions: SU01 (User Maintenance), SAP Logon Pad.
