I need to extract first ORDER ID of a customer based on the pickup date

[Andrew_na_lang]

Hi Fam, 

I have a situation whereby our order ids are alpha-numeric and it is not arranged alphabetically, it is a unique random order id. I need to extract the earliest order id based on the pickup date. 

I am creating a column in my customer's table and I am pulling the data from my order's table. 


I used DAX: 

CALCULATE ( MINX ( order_alpha_id)) 

But I realized that I am pulling up the order id based on the letters not the pickup date.

@Andrew_na_lang Try:

Measure = 
  VAR __MinDate = MINX(ALL('Table'),[Pickup Date])
  VAR __OrderID = MINX(FILTER(ALL('Table'),[Pickup Date] = __MinDate),[order_alpha_id])
RETURN
  __OrderID
