• What is the cause and solution for SAP error message SQLM112 - A trace activation with empty request filter already exists ?

  The SAP error message SQLM112 indicates that there is an attempt to activate a trace with an empty request filter, but a trace with the same parameters is already active. This typically occurs in the context of performance analysis or monitoring using the SQL Trace (ST05) or similar tools in SAP.
  Cause:
  The error is caused by trying to activate a trace without specifying any filters, while another trace with the same empty filter is already active. This can happen if:
  
  You are trying to start a trace without defining any specific criteria.
  There is a misunderstanding in the trace activation process, leading to multiple attempts to activate the same trace.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Check Active Traces: 
  
  Go to transaction code ST05 (SQL Trace) or the relevant transaction for the trace you are working with.
  Check if there is already an active trace with the same parameters (i.e., an empty request filter).
  
  
  
  Deactivate Existing Trace:
  
  If you find an active trace that you do not need, deactivate it. You can do this by selecting the trace and choosing the option to deactivate or stop the trace.
  
  
  
  Specify a Filter:
  
  If you need to activate a new trace, consider specifying a request filter to differentiate it from the existing trace. This can help avoid conflicts.
  
  
  
  Restart the Trace:
  
  After deactivating the existing trace or specifying a new filter, try to activate the trace again.
  
  
  
  Check for Background Jobs:
  
  If the trace is being activated as part of a background job or automated process, ensure that the job is not trying to activate the trace multiple times without deactivating it first.
