In FLA system, we have defined the approval rules by using “Abstracted by” filed. 

Creator of Lease record will provide the Approver User name in “Abstracted by” field, but we have noticed that Creator can assign his/her user name as well. 

We have configured Self approval restriction as well, which is working fine, but we were unable to restrict the user from assigning the Lease record to own self. 

Noticed that this is not feasible through form personalization as well. 

Can we expect this restriction in new release.
