Sum of quantity based on latest file date of each item

I have an inventory fact table with fields: file date, items, available quantity, and store number. The different stores will upload their inventory multiple times through the day but it could be at different time stamps. I'm looking to find the available quantity for each item and store for the most recent file date.

Here's a sample table:

file date	our_item_number	available	store
4/10/24 10:00 AM	123	800	5
4/10/24 11:00 AM	123	2250	5
4/10/24 12:00 PM	123	8750	5
4/10/24 10:00 AM	223	500	5
4/10/24 11:00 AM	223	1000	5
4/10/24 12:00 PM	223	1500	5
4/10/24 11:00 AM	223	-2100	7
4/10/24 1:00 PM	223	-1050	7

Here's the measure that I've been using:

OH QTY = var maxdate = CALCULATE( MAX(Inventory[File Date]) ) return CALCULATE( SUMX('Inventory','Inventory'[Available]), Inventory[File Date] = maxdate )

This works for the item/store level but it does not total correctly. It gives me only the sum of the available qty for the max value of the file date.

example of actual output:

store	our_item_number	OH QTY
5	123	8750
5	123	1500
7	223	-1050
TOTAL		-1050

output that I want:

store	our_item_number	OH QTY
5	123	8750
5	123	1500
7	223	-1050
TOTAL		9200

From what I've read, it may be something to do with row context but I can't quite figure it out.

Any thoughts/comments are appreciated!

Hi 3rdAbnormalForm

please try

OH QTY =
SUMX (
SUMMARIZE ( Inventory, Inventory[store], Inventory[our_item_numver] ),
SUMX (
TOPN ( 1, CALCULATETABLE ( Inventory ), Inventory[File Date] ),
Inventory[Available]
)
)
