'How to get the earliest date from another table in a one to many relationship?
I have these two tables. Both tables have a relationship by id (one to many)
TableA
id
1
2
3
TableB (date field is a date/time datatype)
id date
1 1/01/2022 09:00:00
1 1/01/2022 11:00:00
2 1/01/2022 14:00:00
2 1/01/2022 18:00:00
2 1/01/2022 21:00:00
3 1/01/2022 09:00:00
3 1/01/2022 09:10:00
I require to add a calculated column in tableA that takes the earliest date of each id from tableB

You can use CALCULATE and FILTER DAX formulas to accomplish this
Date Lookup =
CALCULATE(
MIN(TableB[date]),
FILTER(TableB,
TableA[id]=TableB[id]))
