I am creating a per week rollup that shows a sum of the children rows from another sheet. It looks to me like SUMIFS does not work if the range referenced contains a formula. Is this a bug, limitation, or do i have an error in my formula?
=SUMIFS({ManpowerPerTaskApp}, {ManpowerWorkingStart}, WEEKNUMBER($Date@row) = WEEKNUMBER(@cell), {ManpowerWorkingStart}, YEAR($Date@row) = YEAR((@cell) - (WEEKDAY(@cell) - 1) + 1))
This is returning #INVALID DATA TYPE when the values in {ManpowerPerTaskApp} are the formula:
=SUM(CHILDREN(App@row))
The exact same SUMIFS formula works fine if the {ManpowerPerTaskApp} range points to data that are numbers (such as the data in the 'App' column on the referenced sheet) as opposed to number as a result of a formula
