Function Module to Fetch Average Database time per Dialog Step

Hello,

I need the Functional Module to get the ST03n data for average Reposetimes for Dialog.

I used the FM - 'SAPWL_WORKLOAD_GET_SUMMARY' by which I am able to calculte the Average Response Time, Average GUI Time, Average CPU Time, but I am unable to get the Average Database time per Dialog Step.

Can anyone has the idea which FM is able to fetch this data?
