HOW CAN I CREATE A DYNAMIC DATE TABLE FROM AN EXISTING DATE TABLE IN MY MODEL

[Anonymous]

Hi,

I have a line graph to create and need it to show total of 3 years back from any date selected.

The data will also be filterable afterwards. 

I need to create a seperate date table from an existing date table to use as a filter for the line graph.

How can achieve this such that the new date table is dynamic ie. minimum date is 3 years before maximum date of original table and the maximum is the maximum selected date on the original date table

Hi @Anonymous ,

If you need create a new data table you can use DAX CALENDAR(<start_date>, <end_date>)  to do that.

Some dax code like the following:

New date table =
VAR _MIN =
    MIN ( 'original date table'[Date] )
VAR _MAX =
    MAX ( 'original date table'[Date] )
RETURN
    CALENDAR ( DATE ( YEAR ( _MIN ), MONTH ( _MIN ), 1 ), _MAX )

Best regards.

Hi  @Anonymous 

You no need another date table. You can get from one single date table. If you DAX filter context then it will be simple.
