I am trying to create a calculated column in SAS Data Prep. Max(Date) by ID.
ID Date
1 09/06/89
2 01/19/93
3 09/08/93
1 09/04/85
1 09/04/91
2 09/09/92
I used the max(date) function but it returns the same date value.
You have to ensure you do it for the BY group. This may be easier as a calculated measure (I'm assuming SAS VA) that allows you to do a Grouped calculation.
I am on SAS VIYA 3.3. I am using a web based client of VA.
