• What is the cause and solution for SAP error message CU760 - The maximum number of alternative sessions has been reached ?

  The SAP error message CU760, which states "The maximum number of alternative sessions has been reached," typically occurs when a user tries to open more sessions than the system allows. In SAP, a session refers to an instance of a user interface where a user can perform transactions or access data. Each user has a limit on the number of sessions they can open simultaneously.
  Cause:
  
  Session Limit Reached: Each user has a predefined limit on the number of sessions they can open. This limit is set in the SAP system configuration.
  Unclosed Sessions: Users may have multiple sessions open and may not have closed some of them, leading to reaching the maximum limit.
  System Configuration: The system may be configured to allow a limited number of sessions per user, which can be lower than what the user needs.
  
  Solution:
  
  Close Unused Sessions: The simplest solution is to close any unnecessary sessions. You can do this by navigating to each session and logging out or closing the window.
  Check Session Limit: You can check the maximum number of sessions allowed for your user profile. This can be done by:
  
  Going to transaction code SU01 (User Maintenance).
  Entering your user ID and clicking on the "Parameters" tab.
  Looking for the parameter ztt (number of sessions).
  
  
  Increase Session Limit: If you frequently need more sessions, you can request an increase in the session limit from your SAP administrator. They can adjust the settings in the user profile or system configuration.
  Log Off: If you are unable to close sessions, you may need to log off from the SAP system completely and log back in to reset your session count.
  
  Related Information:
  
  User Profile Settings: The session limit can be configured in the user profile settings. The parameter ztt controls the maximum number of sessions.
  System Parameters: The overall system settings can also limit the number of sessions. This can be checked by the system administrator.
  SAP Notes: You can refer to SAP Notes for any specific patches or updates related to session management.
  Best Practices: It is a good practice to regularly monitor and manage your open sessions to avoid hitting the limit.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or system administrator for further assistance.
