• What is the cause and solution for SAP error message 0S100 - Performance trace was already switched on for all users at & ?

  The SAP error message "0S100 Performance trace was already switched on for all users at &" typically indicates that the performance trace (ST01 or ST05) is already active for all users in the system. This can happen if a previous trace was not properly stopped or if the system settings have been configured to enable tracing for all users by default.
  Cause:
  
  Trace Already Active: The performance trace has already been activated for all users, and an attempt is being made to activate it again.
  System Configuration: The system may be configured to automatically enable tracing for all users, leading to this message when trying to activate it again.
  User Permissions: The user attempting to activate the trace may not have the necessary permissions to modify the trace settings.

  Check Current Trace Status:
