How to combine multiple tables in power BI

Question

I have three tables whose structure is as follows-

Table 1-

Table 2-

Table 3-

I wanted to have a table like this -

I tried this particular formula for creating a calculated table-

Table = UNION(SELECTCOLUMNS(Table1,"Table1", Tables[Table1]), SELECTCOLUMNS(Table2, "Table2 Totals", Table2[Totals]), SELECTCOLUMNS(Table3, "Table3 Totals", Table3[Totals]))

The result I am getting is like this:-

I have no idea why this is happening. What to do in this scenario? Do calculated columns not come in merge query?

Hi Sindhu,

You can merge the 3 tables into a new table to get the required output that you want.

1.  Merge TABLE1, TABLE2.  ---------->     NEW TABLE    [ columns - Table2, Name ]

2.  Select all column from TABLE1.  Select 1st and last column of TABLE2 IN THE NEW TABLE.

3.  Merge TABLE3, NEW TABLE  ------------->   NEW TABLE.     [ columns - Table3, Name ]

4.  Select only 1st column from TABLE 1 And last columns of TABLE  2, TABLE 3.

5.  You will get the required result.

Hope this helps you.
