How to create a measure that will show your Top sales day for each location

[OCBB_SFAFPandA]

Hello,

I am trying to find a measure that will look for the highest sales record for a location and return thant # and the date it made the record. I need this for each location.

When I am researching, a lot of the solutions use something like:

CALCULATE(SUM('Table'[Sale amount]

but my sales amount is a measure and not a column, so it's not working well with the sum function.
