## Multiply 2 columns from 2 different data tables

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

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
