Merge Tables duplicate rows

I have two tables, first "EC", second "NE".

In the table "EC" i have the ref "Five" one time, but in table "NE" i have the same ref in two rows.

When i merge two tables with a key that i have created "chaveec" (key+ref) the merge table duplicates my rows.

 

 
 

The wrong result is that:

But i want this:

Can you help me please?

 

 

 

  • Hi , ruinaldo 

    As mentioned by parry2k ,both of the merged tables have two pieces of data with a "chavee" of 5, Powerbi cannot determine which record in Table 1 matches with which record in Table 2, so 2 * 2 records are generated.

    It is suggested to create custome column "chaveec" (key+ref +number) as a key to merge rows.

    Here  is a demo . Please  refer to the query "merge2"

  • ruinaldo In the screenshot, first table (EC), you have five twice, not one time? Am I missing something?
