Hi,

The article you highlighted takes us to 6.2 sp2 help document and it talks about "How to disable operator id " rather than " How to delete operator id " as deleting operator id is not a good practice.

The article says :

If a user is no longer active, rather than deleting the Operator ID instance, you can follow these steps:

• Ensure that this user is not currently logged in.
• Transfer or complete all assignments on the worklist.
• Update the password to a value that is not disclosed to the user, so that person can no longer log in.
• Ensure that this user has no rules checked out. If not, sign on and delete or check in the checked-out rules.
• Clear the Operator is available to receive work? checkbox.
• Enter a departure date in the Unavailable from array.
• Enter a substitute operator for assignments routed to this operator.
• Save the updated Operator ID instance.

If you want to delete them instead of disable, then you have to create your own activity. The activity can contain 2 steps.

Step 1 : Obj Browse : To fetch the operator id records from data base

Step 2 : Obj-Delete :  To delete the data

You can refer the activity  :  DeleteAllOperators ( of class : PegaAccel-Task-GenerateApp ) to get an idea of the same.

Please note that I have not tried this in house so not sure about the outcome. Hence , taking database back up before performing this exercise is highly recommended.
