Linking two aggregated tables

Hello,

 

I have two tables aggregated from two sources each: table 1 and table 2

In table 1 i have columns: unit code (unique and not repeating), number of subscribers 1

In table 2 i have columns: unit code (can repeat for some rows), number of subscribers 2, chanel health (has three possible values: good, weak, excellent)

 

I want to create a merge table which will link these two tables based on unit code and give as a result a table containing the following columns: Unit code, number of subscribers 1, number of subscribers 2, chanel health

 

Using DAX expression in Power BI, I tried this: Merged_Table = NATURALINNERJOIN(table 1, table 2) but it says: No common join columns detected.  although unit code is a commun column......

 

Can you help me please I am blocked

Thanks

Hello @Anonymous ,

 

use lookup value to get column from another table based on a common column.

Sorry that did not work... Can you please give me an example of a power query to do the merge? I can't establish the merge because my key is not unique so I am really struggling

It because my aggregated tables 1 and 2 does not show at all in power query editor... I only have the sources tables A and B to which no filter was applied. Table 1 and 2 are filter versioin of A and B respectively

Hello @Anonymous ,

 

why don't you make it through power query, its much easier and straight forward.
