I have a pivot table that takes a resources % utilisation each month for each project they are on, shows it as a SUM, and sumarises by what department they are in. This looks like:
Jan-15 Feb-15
Department Subtotal Subtotal
Joe Bloggs 20% 10%
Fredd Bloggs 60% 30%
I want the Subtotal for Department to show the AVERAGE of the percentages shown in the pivot table (so above it would be 40% for Jan-15 and 20% for Feb-15). However, if I select the format as AVERAGE, it returns the AVERAGE of all the data behind the pivot table, which gives me different figures as each person may be working on several projects.
Is there any way I can get the Subtotal to calculate differently?
Thanks.
