Display selection of slicer value as static value in table

[rsaphier]

What would be the correct DAX syntax to use based on this example?

There is a slicer in PBI for Selected  Period  which is filtered to Apr-2019.   For the Selected Period  in the table below,  I need to display this value (as static) for each Reporting Month.   The interaction between the slicer and the table is set to none. 

Reporting Month	Selected Period
Jan-2019	Apr-2019
Feb-2019	Apr-2019
Mar-2019	Apr-2019
Apr-2019	Apr-2019
May-2019	Apr-2019
Jun-2019	Apr-2019
Jul-2019	Apr-2019
Aug-2019	Apr-2019
Sep-2019	Apr-2019
Oct-2019	Apr-2019
Nov-2019	Apr-2019
Dec-2019	Apr-2019

My current logic just repeats the respective Reporting Period. 

Selected Period =

VAR selectedPeriod =
    IF (
        HASONEVALUE ( 'Reporting Period'[Reporting Month ] ),
        SELECTEDVALUE ( 'Reporting Period'[Reporting Month] ),
        0
       )

RETURN
       selectedPeriod

@rsaphier your report period and selected month are from same table or seperate tables?

They are from the same table.
