how to update HRMS self-service approval process for sick leave type

Hello,

I'm using HRMS self-services for ebs R12.1.3

actually when employee submit any absence leave type, it goes directly for his manager for approval and after his manager approval FYI goes to HR

i need to separate sick leave as below:

if employee submit sick leave, it goes first for his supervisor for approval, then a second approval should be there from HR team

==> how to proceed for that ?

EBS R12.1.3

DB:12

Kind regards

Chaker
