CALCULATETABLE, SUMMARIZE & LAST MONTH

[jasontran]

Hi,

Hopefully this should be a quick fix for some of the gurus out there.

I've got the following DAX structure to return a summarized view of the last snapshot.

latestview = CALCULATETABLE(
                      SUMMARIZE(

                      table,

                      col1, col2, col3),

                   YEAR(tab1[Effective Date])=YEAR(NOW()) && MONTH(tab1[Effective Date])= MONTH(NOW())-1) 

This generally runs all well to return the latest snapshot loaded (last month) but given the new year fails to render because of the YEAR condition. Is there a better way to construct the filter to return last month?

Try This. I have not tested this

latestview = CALCULATETABLE(
                      SUMMARIZE(

                      table,

                      col1, col2, col3),

                   YEAR(tab1[Effective Date])=YEAR(date(YEAR(TODAY()),MONTH(TODAY())-1,DAY(TODAY()))) 
				   && MONTH(tab1[Effective Date])= MONTH(date(YEAR(TODAY()),MONTH(TODAY())-1,DAY(TODAY()))) 

Or

latestview =
Var _date = date(YEAR(TODAY()),MONTH(TODAY())-1,DAY(TODAY()))


return
 CALCULATETABLE(
                      SUMMARIZE(

                      table,

                      col1, col2, col3),

                   YEAR(tab1[Effective Date])=YEAR(_date) && MONTH(tab1[Effective Date])= MONTH(_date)
