0S138 - Details

• The SAP error message 0S138 ("You have not selected a trace to analyze") typically occurs when you are trying to analyze a trace in the SAP system, but you have not selected any trace data to work with. This can happen in various contexts, such as when using transaction codes like ST05 (SQL Trace) or ST12 (Single Transaction Analysis).
  
  Cause:
  
  No Trace Selected: You may have accessed the trace analysis tool without selecting any specific trace entries.
  Trace Data Not Available: The trace data you are trying to analyze may not exist or may have been deleted.
  Incorrect Filters: If you have applied filters that do not match any existing trace entries, the system will not find any data to analyze.
  
  
  Solution:
  
  Select a Trace: Ensure that you have selected a specific trace entry before attempting to analyze it. In transaction ST05, for example, you need to activate the trace and then select the relevant trace
