Helper I
Helper ISELECTCOLUMNS
Hi,
I am fairly new to DAX and came across this line of code which I am unable to understand.
If understand correctly SELECTCOLUMNS take table as first argument. But in the case below {"Last 2 Months"}
doesn't exist. Also, not sure where [Value] is coming from and how its being recognized. Any help would be appreciated.
DAX:
Tbl =
SELECTCOLUMNS({"Last 2 Months"},"Period",[Value])
Result:
Period
----------------
Last 2 Months
-----------------
Thanks

What are you trying to do ?
SELECTCOLUMNS selects the columns you want to keep from a table, create new headers and/or add some expressions.

SELECTCOLUMNS({"Last 2 Months"},"Period",[Value])
Yes, but in this case neither the table exist nor the [Value] but its still giving me results.

Thanks.
I think I get it. Its creating a table using table constructor
{"Last 2 Months"} and the then pulling the Value using SelectColumns.
