It is not possible to put both in Union directly,
The group coming to Union must have same number of columns
and its data type must be compatible.
In this case first table has 4 columns and the second table
has 3 only.
alternatively you can follow the below logic to pass to
union transformation
Because the 2nd table has only 3 columns, create dummy
column for the 2nd flow and pass null in that port, so that
you can connect them to Union

Answer / pavana
Yes , we can created 2 input groups with 4 columns . For 1st
input group pass all columns from table 1 ,for 2nd input
group pass all 3 columns from table 2, 4th column from in
2nd group remain unconnected.
Session executes successfully. output will be the union of 2
tables. The 4th column from 2nd table will be populated as
null in output.

Answer / sudheer
No need to create any dummy column(table-2) and make it as null...
Just create 2 groups as u have 2 tables and create 4 group ports like below Empid,firstname,lastname,middlename.
-Drag respective columns from src to union.
-Don't make any link for middle name from table as we don't have any column but drag all columns from table 2 and save the mapping and run the session.....This will work as i have tested.Thanks......
