Hi,
I have a problem with the operation of the formula in the analysis.,
I'm trying to use the functions AGO on operations SUM (TIMESTAMPDIFF ())
In my analysis I have:
![]()
Formule for NOW column:
SUM(TIMESTAMPDIFF(SQL_TSI_DAY, "Purchase Details"."Due Date", "Purchase Details"."Need By Date"))
Formule for AGO column:
AGO(SUM(TIMESTAMPDIFF(SQL_TSI_DAY, "Purchase Details"."Due Date", "Purchase Details"."Need By Date")),"Time"."Time"."Year",1)
And I get results:

.My question: is it possible to make it work?
