add rows from multiple table with same type

[kesham]

Hello everyone, I am new in power bi and I try to make a table combining rows of 2 table:

for example :

table 1 (column A,B & C) where A is strings, B & C are int with 1000 rows

table 2(column D & E) where D is string and E is int with 500 rows

What I want il making the table 3 with 2 columns (F & G) where F is string and G is int with all the rows ofcouples A&B, A&C, D&E.

At the end Table 3 will have 2500 rows

Can someone help me ?

kind regards

PS: it would be awesom to know from where is the data with a new strin column H with 3 cases ("Table1 A&B";"Table1 A&C";"Table2 D&E") just to know where the data is from.

kind regards again 🙂

@kesham - You could combine tables in 3 ways:

1. Prior to bringing in to Power BI

2. In Power Query -

  2.1 Make a Duplicate of Table1

  2.2 Remove B from one of the tables and C from the other.

  2.3 Change column names so that all 3 tables have the same column names.

  2.4 Add a Custom Column to each of the 3 tables, describing the source.

  2.5 Append tables together into 1.

3. In DAX: Create a Calculated Table like this:

My Combined Table =

var a = SELECTCOLUMNS(Table1,"F",[A],"G",[B],"H","Table1 A&B")

var b = SELECTCOLUMNS(Table1,"F",[A],"G",[C],"H","Table1 A&C")

var c = SELECTCOLUMNS(Table2,"F",[D],"G",[E],"H","Table2")

return UNION(a,b,c)

Cheers!
