• What is the cause and solution for SAP error message 0S124 - No filter is set - the performance trace is deactivated ?

  The SAP error message "0S124 No filter is set - the performance trace is deactivated" typically occurs when you are trying to analyze performance traces in SAP but have not set any filters for the trace data. This can happen in transaction codes like ST05 (SQL Trace) or ST12 (Single Transaction Analysis), where performance tracing is used to monitor and analyze the performance of database operations and other system activities.
  Cause:
  
  No Filters Applied: The primary cause of this error is that you have not set any filters for the performance trace. Without filters, the system does not know what specific data to capture or analyze.
  Trace Deactivation: The performance trace may be deactivated, meaning that no data is being collected for analysis.

  Set Filters: 
  
  Go to the relevant transaction (e.g., ST05 or ST12).

  After setting the filters, activate the trace again.
  
  
  
  Activate the Trace:
