Dynamic flag for date selection

[ANILKORLIMARLA]

i have month start date field in my data, and a slicer on that same field,

when i select some value in slicer i want to calculate -12 months from the selected value and flag then as "Y" and rest as "N"

this should be dynamic based on the slicer selection all the time
