Create a reference table from three tables

[vyny17]

Hi there, Power BI enthusiasts and specialists!

Here is the trouble:

I have three different tables, each table has the same three columns, these columns tell the respective client, the client's departament and the client's salesman (the data is always standardized). There are other columns in each one of theses table that inform other kind of data, but that's not relevant to the problem.

Here is an example of these tables:

I want - using DAX or Power Query - to create a fourth table that reunites all of these three columns (the set of three columns cannot have duplicates), this table must seem like this:

It must act like a reference or dim table, how can I do that?

Hi vyny17,

Here's a solution:

Create a new table Table4, with the following DAX formula:

Table4 =

Var Tablea=SelectColumns('Table1',

                                            "Client",[Client],

                                           "Department",[Department],

                                           "Salesman",[Salesman]

                                          )

Var Tableb=SelectColumns('Table2',

                                            "Client",[Client],

                                            "Department",[Department],

                                            "Salesman",[Salesman]

                                           )

Var Tablec=SelectColumns('Table3',

                                           "Client",[Client],

                                            "Department",[Department],

                                            "Salesman",[Salesman]

                                          )

Var UnionTable = union (Tablea,Tableb,Tablec)

Var finalTable = SUMMARIZE(UnionTable,[Client],[Department],[Salesman])

return finalTable

Note that I've assumed that your first table is called Table1,  that your second table is called Table2, and that your third table is called Table3.
