Prior year calculation problem

[#1]

Hi guys. Currently I have a actual sales calculation like this

=sum(SalesAmount)-sum(SalesAmount*(DiscPrcnt/100))-sum(CreditAmount)+sum(CreditAmount*(CNDiscPrcnt/100))

I want to compare prior year actual sales with current year actual sales. I got this formula in the forums:

num(sum({$<Year = {$(=only(Year) - 1)}, Month = {"<=$(=max(Month))"}>} SalesAmount), '#,##0;(#,##0)')

I do not know how to place the actual sales calculation as mentioned on top into this formula. As you will see that this formula only sum(SalesAmount), but I need to add the whole calc as shown on top.

Could someone please assist me. It looks like some simple answer.

Try like this

=num(

sum({$<Year = {$(=only(Year) - 1)}, Month = {"<=$(=max(Month))"}>} SalesAmount)-

sum({$<Year = {$(=only(Year) - 1)}, Month = {"<=$(=max(Month))"}>} SalesAmount*(DiscPrcnt/100))-

sum({$<Year = {$(=only(Year) - 1)}, Month = {"<=$(=max(Month))"}>} CreditAmount)+

sum({$<Year = {$(=only(Year) - 1)}, Month = {"<=$(=max(Month))"}>} CreditAmount*(CNDiscPrcnt/100))

, '#,##0;(#,##0)')
