HI @jfant001 ,
Thanks for your query. Before going to create your calculated field as DD:HH:MI:SS you need to first create your date difference that is Call Start Time and Call End Time duration as sec.
Step -1
dateDiff({Call Start Time},{Call End Time}, ‘SS’)
Step - 2
Use this below formula
The yellow highlighted area is the field name of your date duration between start time & end time.
Note - You can not plot this data on KPI visual type.
If you want to Create DD:HH:MM:SS format for line level then just go to the Demo Central and see the detailed analysis it is very easy to understanding all the calculation.
