VLOOKUP with MAX

[joshua1990]

Hello everyone!

I have two tables:

tblOrder

Order	Date	Value
1001	01.01.2020	500
1002	01.01.2020

tblWork

Order	SEQ	State	String
1001	50	1	AAA
1001	50	2	BBB

Now I would like to add the first table a calculated column that shows me the String for the row of tblWork where SEQ & State = MAX

How would you do that?

// Please note I'm not using CALCULATE here
// because if the tblOrder table is big,
// it would be agonizingly slow.
[String] =
var __order = tblOrder[Order]
var __maxSEQ =
	MAXX(
		topn(1,
			filter(
				tblWork,
				tblWork[Order] = __order
			),
			tblWork[SEQ],
			DESC
		),
		tblWork[SEQ]
	)
var __maxState =
	MAXX(
		topn(1,
			filter(
				tblWork,
				tblWork[Order] = __order
				&&
				tblWork[SEQ] = __maxSEQ
			),
			tblWork[State],
			DESC
		),
		tblWork[State]
	)
var __string =
MAXX(
	filter(
		tblWork,
		tblWork[Order] = __order
		&&
		tblWork[SEQ] = __maxSEQ
		&&
		tblWork[State] = __maxState
	),
	tblWork[String]
)
return
	__string

Thanks for your approach! Unfortunately, I get the following error:
Calculation error in measure YXX : A single value for column 'XX' cannot be determined in table 'XX'. This can happen when a measure formula references a column that contains many values ​​without specifying an aggregation such as 'min', 'max', 'count' or 'sum' to get a single result.

This is not a measure. It's a calculated column. This is what you asked for.
