Restrict Approval request to a user to whom its submitted for

Summary:

Hi-

We got a role based approval configurations. Requirement here is, if a HR specialist submits an Allowance for any employee it should go to HR business partner approval (who is also a employee in the system)

Now, if a HR Specialist submit a allowance to a employee (who got HR Business partner role also) the approval request is going to all the users having HR business partner role including the employee to whom the allowance is submitted against.

now the employee(who is HR BP also) is able to claim the request and approve the allowance given to him. or even edit the transaction.
