Hi Pramodh
We really do not know how you are sending the workitem to the approvers in a sequence.
If its in a loop, as Rick mentioned, you can use a condition to check if current approver is the WF initiator, then bypass that level.
If you are using Dynamic 'sequential' processing, make sure you knock off the WF initiator first. In the method where you are determining the WF Approvers, pass the WF initiator as well and knock it of from the list of approvers before passing them back to ACTAPPROVER.
Of course, you will also have to check if the Approver list is empty after this operation, you trigger an exception so as to prevent the WI going to All (if your decision task is set to general).
