New measure Dax formula needed

[AtulSutar]

I have OLAP source file and in that file, I want to have the sum of the particular item group. 

e.g. there are many item groups like 72absc, 72dmap, 40abds, 23asrt and there is sales value for these group.

I need sum of values only for 72dmap item group.

Kindly help.

Hi @AtulSutar ,

Try a measure like this:

_72dmapSales =
CALCULATE(
    SUM(yourTable[Sales]),
    yourTable[Item Group] = "72dmap"
)
