count rows but total must show max count

[Anonymous]

I need to show in a table object the total calls of a callcenter per day. (dax counta in the fact table)

But the total column on the end of the object must show the max value from any day, not the total count.

Example: 10, 20 and 15 calls in 3 days. Total column must show 20 (max value from any day) and not 45 (sum).

I am trying a lot of DAX, using summarize etc...

So far, did not get what I need.
