Hi Ansumesh,
There is first step for user decision in which to approve of reject a mail. Agent here is US User with a user ID . After this , there are 2 mail for approval or rejection where the recipient is workflow initiator(expression) .
I executed the workflow . The user accepted/rejected it.. but m not getting mail after this that the user has accepted/rejected the same.
If i executes the same workflow in other system ,then m getting the mail in sost.
I think its a configurartion issue. Don't know which settings needs to be done.
