Hi
I am trying to calculate weekly averages of hours worked per employee

My data structure is as following

employee Table

empId
empName


service table
serviceId
empId
DateComplete
BillableHours

Report structure should be like this:

GH1 - Employee name     Average Weekly Hours
   GH2 - Week of (based on DateComplete )  - Total hours (sum of BillableHours)
      D - suppressed - no drill down


I have all done except  Average Weekly Hours

Can anybody point me to the right direction?

One way to try is a formula like

Sum({BillableHours},{EmployeeId}) / DistinctCount({DateCpmplete},{EmployeeName})

You could use running totals or formulas but those methods wouldn't give you the ability to put it in the group header.
