Hi Baharul,
I agree with Norberto that there is no webMethods out-of-the box solution for your problem. Or, if there is, I am not aware of it.
However you can implement this logic. My idea is to keep an approval string list in every task business data. Whenever a user click on the “Complete” button, the code checks if he is the last approver or not. If he is not, only a save (applyChanges) is done. If the current user is the last approver then the task is completed.
In my idea the verification is done by checking the equality between the string list from the task data and the string list that holds the group members.
Also you may want to add some “invisibility” functionality so that the tasks that are approved by an user do not appear anymore in the user’s inbox.
Hope this helps,
Vlad Turian
