Hi @Tammisetti Renu ,

If you're looking for something like the screenshot that you have attached, you need to utilize performance analytics / platform analytics with automated and formula indicators. The reason for this is, as far as I can see you would like to have all SLAs for e.g. workplace in a month and calculate an average. 

So one automated indicator to sum the SLA percentage, one automated indicator to count the SLAs within e.g. workplace, and then calculate the average in a formula indicator.
