Creating new table using existing

Hi,

 

I am trying to create new table using existing tables as shown in the example below

 
 
TABLE_ATABLE_BTABLE_CTABLE_D
1-A1-B1-C1-D
2-A2-B2-C2-D
3-A3-B3-C3-D
4-A4-B4-C4-D
RESULT_TABLE
1-A1-C
2-A2-C
3-A3-C
4-A4-C
1-B1-D
2-B2-D
3-B3-D

Can someone please help me with the DAX for the same.

 

Thank you🙂

Hi @Anonymous ,

 

"TABLE_A", "TABLE_B" are column names, right? If so, try this:

New Table =
VAR t1 =
    SELECTCOLUMNS ( 'Table', "Column 1", [TABLE_A], "Column 2", [TABLE_C] )
VAR t2 =
    SELECTCOLUMNS ( 'Table', "Column 1", [TABLE_B], "Column 2", [TABLE_D] )
RETURN
    UNION ( t1, t2 )

@Anonymous , Create a copy of this table in power Query.

In the existing table drop column table_B , Table_D

and new Table table drop column table_A , Table_C

 

append these two tables

@amitchandak  Thank you for your respond.

but actual tables are containing rows in millions hence processing time with this method is more than accpetable. 
Is it possible to do it with DAX in one step or faster?

 

Thanks
