Hi everyone.  I have a list of inventory from multiple locations that was taken on different dates.  I need to know the current total inventory for each item using the last date posted from each location.  Here is an example of my data

Date	Location	Item	Quantity

Hi @SharonCNE ,

Try those measures:

_LastDate = CALCULATE(MAX('Table'[Date]); ALLEXCEPT('Table';'Table'[Item]))

Measure = CALCULATE(SUM('Table'[Quantity]); FILTER(ALLEXCEPT('Table'; 'Table'[Item]); 'Table'[Date] = [_LastDate]))

Ricardo thanks for answering so quickly - im getting this error

The function SUM cannot work with values of type String

@SharonCNE ,

Be sure the quantity column is numeric.

Ricardo - yes value is a whole number :). the item is Text but I can't change that

[SharonCNE]

Ricardo - I was just looking at your result table and It's actually the result I'm looking for:

If you look at the data provided

Item 3 has 10 entries

3/31/20 location A 0

4/10/20 location A 377

4/14/20 location B 3

4/14/20 location C 7

4/14/20 location E 12

4/15/20 location F 110

4/15/20 location G 10

4/16/20 location A 1525

4/17/20 location A 1475

the measure I am trying to create would look at that - determine the latest date for EACH location and SUM all those together - in this example it would be the amounts shown for B + C + E + F + G and ONLY the amount for A on 4/17/20 (because it was the latest date it was reported at that location)

and so on and so forth.  Does that make sense?

Hi @SharonCNE ,

Try this measure:

Measure =

SUMX(

ADDCOLUMNS(

SUMMARIZE('Table';

'Table'[Item];

'Table'[Location];

"Max"; MAX('Table'[Date]));

"Value"; CALCULATE(SUM('Table'[Quantity]); FILTER('Table'; 'Table'[Item] = EARLIER('Table'[Item]) && 'Table'[Location] = EARLIER('Table'[Location]) && 'Table'[Date] = [Max])));

[Value]

)

Ricardo - that was it!! thank you. Much more complicated than I could have figured out 🙂
