Measure iterating subset of data

Mike_0828 — Wed, 17 Jul 2019 14:51:36 GMT

Hi guys!

I have a Fact table with accounts receivable (AR) and accounts payable (AP) amounts for each counterpaty.

The goal is to create measure with settlement amount equals MIN of AR and AP.

My current measure (Settlement_amt) works fine if I specify counterparty code as context, but if my context is Region or Category it works incorrectly.

I would like to create a measure which iterates over Dim_Cust_Vend and calculates Settlement_amt individually.

Solutions are very appreciated!!

Mate, you say:

Well, if it calculates Settlement_amt individually, then it must do something with the amounts because a measure can only return a number or text. So then, what do you want to do with the amounts? Take an average? Sum them up? Take the min or max? What's the aggregator for the amounts?

Darek,

I'd like to sum up settlement amount when Region or Category is specified as a filter for Dim_Cust_Vend.

-- Replace your old Settlement_amt with the following:

[Settlement Amount] =
var __settlementAmount =
	SUMX(
		VALUES( Dim_Cust_Vend[Code] );
		MIN( [AR]; [AP] )
	)
return
	__settlementAmount

-- This will work in any scenario and is an extension of the old measure.

This brief formula really works!

Could you explain the meaning of VALUES()?

I tried to remove VALUES from formula and system showed me an error:

A single value for column 'Code' in table 'Dim_Cust_Vend' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.
