In Lumira Desktop, you can enable tracing in BO_Trace.ini file. Here are the steps:

  1. Close the SAP Lumira Desktop.
  2. Locate the file BO_Trace.ini under path: C:\Program Files\SAP Lumira\Desktop
  3. Create a backup of this file. You can revert to disable the tracing more easily.
  4. Run Notepad as Administrator and open the above file.
  5. Comment out the top line by putting // in front of it.
         This will change [from_subunit(“com.sap.hilo”) || from_subunit(“com.sap.bi”)] so it looks like this
         //[from_subunit(“com.sap.hilo”) || from_subunit(“com.sap.bi”)]
  6. Change the level of logging by changing this:
         active=true;
         // TraceLog importance level.
         // Default value: m
         // Possible values: xs, x, m, l, xl, ‘<<‘, ‘<=’, ‘==’, ‘>=’, ‘>>’
         importance = m;

    To this:
         active=true;    
         // TraceLog importance level.
         // Default value: m
         // Possible values: xs, x, m, l, xl, ‘<<‘, ‘<=’, ‘==’, ‘>=’, ‘>>’
         // importance = m;
         log_level = high;

  7. Optionally you can change the default logging folder to make the logs easier to find by commenting out log_dir = getenv(“TMP”) + “/sapvi/logs”; to a logging directory of your choice. For example you could change it to:
         //log_dir = getenv(“TMP”) + “/sapvi/logs”;
         log_dir = “c:/logs“;
  8. Restart the application
  9. Reproduce the problem workflow leading to error
  10. Locate the log file under the path you specified or the default location: C:\Users\<user>\AppData\Local\Temp\sapvi\logs
  11. Search for log entries prefixed with |E|

To disable the trace, please remember to amend the BO_Trace.ini line: active = false;
