Answer / bidhar
Sources should be Homogeneous.Though they might not have a
joining condition.
For Example If you have Employee table and Dept Table and
the joining condition is on deptid then its not mandatory
that you must specify the joining condition.If you dont
specify the joining condition then it will have a cartesian
join.
Also the Ports Serial should be same as the SQ override
select.

The Transformation which Converts the source(relational or
flat) datatype to Informatica datatype.
So it works as an intemediator between and source and
informatica server.
Tasks performed by qualifier transformation:-
1. Join data originating from the same source database.
2. Filter records when the Informatica Server reads source
data.
3. Specify an outer join rather than the default inner join.
4. Specify sorted ports.
5. Select only distinct values from the source.
6. Create a custom query to issue a special SELECT
statement for the Informatica Server to read source data.
