Delegation for approval

Question

hello
we have a scenario in SAP HCM to  create a workflow for leave application which should have capability to have a three level delegation of approval. Example if the first approver is absent or the position gets vacant due to any scenario , the workflow should have a capability to move the approval to the next level  , similarly to one more level.
Does standard workflow support this , can this be done in a automatic manner in the UWL in SAP E-portal ?
Your suggestions are welcome.

SAP UWL would support substitution in general and this is not limited to leave.
If you want to automate it then you need to use the badi interface IF_EX_PT_GEN_REQ.
there are various ways you can achieve the required action.
You can use method FIND_RESP_AND_DEFAULT_NEXT_PRC   where you can determine if the respective approver is absent and put the entire logic of handling request.
or you can use CHECK_IF_ACTOR_ABSENT to determine if the approver is absent.
in which ever case you will have to use method  FIND_RESP_AND_DEFAULT_NEXT_PRC to automatically determine approvers.
We have used this approach and we are determining the substitution process for leave.
You can write normal code to determine approver but you will have to push this in the parameters
EX_DEF_NEXT_PROC_ACTOR and EX_RESPONSIBLE_ACTOR.
use below code to feel above parameters using pernr found from your logic.
CLASS ca_pt_req_actor DEFINITION LOAD.
         actor = ca_pt_req_actor=>agent.
         CALL METHOD actor->create_actor
           EXPORTING
             im_actor_type      = 'P'
             im_otype           = 'P'
             im_objid           = <PERNR OF SUBSTITUTE>
           IMPORTING
             ex_actor           = EX_RESPONSIBLE_ACTOR
           EXCEPTIONS
             missing_parameter  = 1
             pernr_not_existing = 2
             application_error  = 3
