Yes, the Sequence generator will reset but there is a
possiblity of session failure. Lets say for the sake of
argument after seq reset initial value is 1. One of the
possible situation for session failure is that if the
sequence generator is feeding any column that has PK or SK
or Unique Index on the target table and the initial value
after reset i.e., in our scenario it's 1 exist in the table
then the session will fail with Database violation error.

Answer / shridhar
We can use one more sequence generator after that sequence
generator or get the value of max key in unconnected lookup
tx and call that value in expression tx and add +1 to the
value and send to the next tx.
Thanks
