How to get minimum of averages

Hello,

Following is my data set where I have captured the average of a column. The average colum is created using a new measure column feature with the AVERAGE function as : AVG_FYTD = AVERAGE(Reporting_KPI_DataNoSecurity[FYTDGIR])

As a next step I want to capture the minumum of this average values. I tried creating a new measure based on the calculated Average column using: MIN_FYTD = MIN(Reporting_KPI_DataNoSecurity[AVG_FYTD]). This does not allow me to capture the Minimum out of AVG_FTYD column.

Any suggestions on achieving this will be great help.

Thank you,
