Hello all,
We can use one Seq by creating reusable transformation in one repository folder and make the repository folder as shared folder.
But one constraint is there the in the question is all about to maintain the uniq key, being a challenge.
I have a suggestion to append a string for each record that is to maintain as S.key in the mapping it self.
like wf -1 will insert 1234A and wf -2 will insert 1235B as uniq key.
I suggest to know the exact functionality of Seq ...:-)

Mapping 1: we will use sequence generator, if key value is null then we will pass nextval else will find maximum of key value then will increment by 1
Mapping 2: same as above
