Rolling Total for Each Warehouse Inventory

[petrodude]

Help! I'm stuck.

I am trying to create a rolling total for each of my 13 warehouses' on hand inventory at the end of each month in Column I

The idea is that if, for a row,

Item = Item

Month – 1 = Month
(Month "0" is the starting inventory at the beginning of the year, Month "1" is January, etc)

Whs = Whs

Then, SUM Net Inventory Cells

Else, ‘’


Here are some screenshots of sample data:
Data filtered for Whs "300" and Item

Data Filtered just for Item

Thank you in advance!

One more try

=IFS(B2=0,"",True,SUMIFS($G$1:G2,$B$1:B2,"<="&(B2-1),$C$1:C2,C2,$D$1:D2,D2))

Eureka! It appears to be working now.

This is amazing. Thank you so so much!
