How to remove "Delegate" option from Reassign Popup page in task details

Question

Hi
I'm using SOA 11g and Jdev 11.1.1.3 for the development. I created a Human task and using the Reassign functionality. From the BPM Worklist, When I click the Reassign in the Actions menu, a popup for Reassign task is displayed. In this popup, I have two options -
1) Reassign (transfer task to another user or group) and
2) Delegate (allow specfied user to act on my behalf)
Functionality of option 1 is working fine. But I do not want to show the option 2 in the popup page.
I tried to find the popup JSPX page and tried to find for any edit options from the BPM Worklist screen, but no luck.
Can anyone throw some light on how I can achieve this.
Thanks,

Hello,
create a new permission level. Copy the "Contribute" permission level and call it "Contribute no Delete". Edit the new permission level and untick the "Delete" box in the List Permissions section.
The next step depends on whether you want this to be site-wide or just for a particular library.
Go to the Approval Task list and click List Permissions in the List ribbon. 
Select to break permission inheritance.
Then select the Sharepoint group that normally has "Contribute" permissions and change the permissions to "Contribute no Delete". To do that, tick the tick box for the group and use the ribbon command to edit permissions for the selection.
