VLOOKUP with MAX

joshua1990 — Wed, 25 Mar 2020 09:29:43 GMT

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.
