why cant we put a sequence generator or upd strategy transformation before joiner transformation?..

Answer / srinivas

Joiner is to join two different sources .If u use Update
strategy T.F and trying to use DD_delete&DD_reject option
the some of the data will get deleted and u can't see the
at joiner output.
So we can't go for this .

why cant we put a sequence generator or upd strategy transformation before joiner transformation?..

Answer / bhupal

if you use the update strategy transformation before joiner in mapping, the mapping will be invalid because of data flow validation errors in mapping irrespective of operations you implemented in update strategy.

joiner transformation input should be from source qualifier transformation.

source---->sq--->seq--->
joiner---->trg
source---->sq---->

we cant create mapping like this because seq does't allows port to create and accept from other tr.

src--->sq--->
joiner--->trg
seq--->
we cant create like this. joiner inputs should be from source qualifier.
