Multiply 2 columns from 2 different data tables

[DatNguyen]

Help me!

I have 2 data tables link with look_up table throug Field PID:

1. Table 1 [PID, Balance] link with Look_up table[PID]: relation n*1
2. Table 2 [PID, RATE] link with Look_up table [PID]: relation n*1

How to calculate field RATE * BALANCE?

I try use SUMX & RELATE, but it not work, becaus 2 data table Tabale 1 and Table 2 not Link directly (relationship type n * n).

Many thanks

Hi @DatNguyen ,

I tested on my side. Here's my data model.

You need to put the [PID] from Look_up table into the visual.

Measure = SUM('Table 1'[Balance])*SUM('Table 2'[RATE])

Wow, It looks more simple. I like your solution.

I will test. Actually Table 1 and Table 2 link with 2 lookup: PID & Currency like that:

Table1 (PID, Currency, Balance)

Table2 (PID, Currency, Rate)

I will try to use your solution to check whether it works. Thank you very much

=sumx(relatedtable(table1),sumx(relatedtable(table2),table1[Balance]*table2[rate]))

Awesome, it works.

But could you help me to understand more about the logic here.

Function SUMX: SUMX(Table, Expression)

• Table: Table in which the expression will be evaluated
• Expression: Expression to be evaluated for each row of the given table
