Which dax statement is more efficient?
Dear users. I was wondering, while building a piece of DAX, if i could improve it or not. Below is a formula i use to calculate the sales in period 1, starting at P1 start and ending at P1 end...
denpries,
In your original post, the P1 Sales* will be more efficient than P1 Sales, and it executes faster than P1 Sales. The DAX Greg_Deckler provides will spend more time to execute comparing with your original measures.
You can use SQL Server Profiler to check the query duration and DAX query plan for these measures and verify the whole process. There are some blogs for your reference.

Perhaps:
P1 Sales = VAR tmpDates = FILTER(FILTER(DateTable,DAY([Dates])=1),[Dates]>=[P1 start] && [Dates]<=[P1 end) RETURN SUMX(tmpDates,[Sales])
