How to calculate future fiscal year dates in load script ?

[Domino1]

 Here is my expression :

vFY0 = 2023  , vFY1 = 2024 , vFY2 = 2025 .....

vMonthNumber = 09

If(Sum({<[Fiscal Year]={'$(vFY0)'},$(vMonthNumber)>} SALES),
If(Sum({<[Fiscal Year]={'$(vFY1)'},$(vMonthNumber)>} SALES),
If(Sum({<[Fiscal Year]={'$(vFY2)'},$(vMonthNumber)>} SALES),
If(Sum({<[Fiscal Year]={'$(vFY3)'},$(vMonthNumber)>} SALES) ,
If(Sum({<[Fiscal Year]={'$(vFY4)'},$(vMonthNumber)>} SALES) )))))

How can I rewrite this in the load script without using variables & set analysis ?

Like this possibly?

FinalTable:
LOAD [Fiscal Year],
Month,
Sum(Sales) as Sales

Resident tmp

Where Month= '09'
and
(Year([Fiscal Year]) >= Year(Today()) and Year([Fiscal Year]) <= Addyears(Today(),5))

Group By [Fiscal Year], Month;

DROP Table tmp;
