Hi,
Various stages available for this requirement. You can use Lookup, Merge or Join based on your requirement.
Go through the document available in you client machine. Else search for keyoword Join or merge or lookup in this forum, you may get the details.

Hi swarnkar,

Make File1 as source and do lookup on File2 and File3 for key column1 and 2 and get the remaining fields.
Or use Merge stage to do the same.

But with this approach i will miss the records which are in file2 and file3 but not in file1

If they're tables, as you say, why not simply join them using SQL? If they're not, load two into hashed files, and do standard lookups in a Transformer stage.

I think swarnkar is working in server jobs and not parallel.

So the join stage need to be cut off.
