Can you use a list created in power query within a Dax variable

Hi Guys 

Can you use a list created in power query within a Dax variable

Example: In power query(M) convert a table to a list. Then reference that list as string variable in Dax

Kind regards

Any legit data type in PQ (list, record, number, text ...) is automatically converted to table when loaded into data model used by DAX.

Can you provide sample data and a depiction of what you are trying to do? There are table functions which can be used in variables, measures and to create new tables.

I am trying to accomplish something like the below:

Test Measure Output =

VAR TableVar =

SUMMARIZECOLUMNS ( 'Measure List'[--Dax_Statement] )

RETURN

CALCULATETABLE(

UNION(

TableVar

))

[dvn_charles]

Where that table variable would be a table of  "select columns"

Hi  @dvn_charles ,

I agree with CNENFRNL , your list will be convert to table automatically in Report View. 

Here I convert Table2 to a List.

List has been converted to a table automatically in Report View.

So you can use it to calculate in your calculation. I have checked your code, and I think it won't be a measure. It should be a calculated table.

There should be two tables in UNION function, so your code will return an error.

It should look like as below.

Test Measure Output =
VAR TableVar =
SUMMARIZECOLUMNS ( 'Measure List'[--Dax_Statement] )
RETURN
CALCULATETABLE(
UNION(
Table1,
TableVar
))

It would be a much more useful help comment if you would show examples of referencing items in the list/table using an Index with DAX syntax and include the output.

Are there data structures available in Dax?
