• What is the cause and solution for SAP error message RIN079 - Logon flag could not be removed for &1. Only one logon language left. ?

  The SAP error message RIN079 indicates that the system is unable to remove the logon flag for a specific user because there is only one logon language left for that user. This typically occurs in the context of user management and logon language settings in SAP.
  Cause:
  The error arises when an attempt is made to remove a logon language for a user, but that language is the only one assigned to the user. SAP requires at least one logon language to be available for each user, so it prevents the removal of the last remaining language.
  Solution:
  To resolve this issue, you can follow these steps:

  Before attempting to remove the existing logon language, you should assign an additional logon language to the user. This can be done through transaction code SU01 (User Maintenance).
  In the user maintenance screen, go to the "Logon Data" tab and add a new logon language.
  
  
  
  Remove the Logon Language:
  
  Once you have added a new logon language, you can then proceed to remove the original logon language without encountering the error.
  
  
  
  Check User Roles and Authorizations:
  
  Ensure that you have the necessary authorizations to make changes to user logon languages. If you do not have the required permissions, you may need to contact your SAP administrator.
  
  
  
  Consult Documentation:
  
  If you are unsure about the logon languages available or how to manage them, refer to SAP documentation or help resources for guidance on user management.
