I am building a metrics sheet for project costings, that references another sheet (time report).
Below are the columns so far and I am looking to add a few more to further break down the data. In the Cost column is the formula =([Days On Site]$2) * [Total Hours]@row, which is referring to the Total Hours multiplied by a specific cost figure from a small table at the top of the sheet.
The below formula calculates the number of hours spent Commissioning for a specific project:
=IFERROR(SUMIFS({Hours}, {Area}, OR(@cell = "Commissioning"), {Project}, OR(@cell = [Primary Column]@row)), 0)
Is it possible to add to this formula to differentiate between Weekday or Weekend hours, which are different rates, and multiply accordingly, i.e. some hours spent Commissioning Mon-Fri, but they also worked Sat-Sun?
