Is there any DAX function that will tell
Is there any DAX function that will tell us period(month/date) of a particular product/customer when it appears for the first time.
EX:
I have a product "X", I can see that under most of the months in a year.
But I want to know in which month it actuall appeared for the first time.
I don't have any startdate field, I need to find the first appearance purely with DAX.
Thanks......
