launch workflow from plsql

Hi,

I create a rule in AME to insert Special Information type (SIT) from self Service. (3 conditions and 2 approvers group).

From self service page it works allright.

I want now to reproduce the same history from plsql procedure (person_id, and others information)

I use wf_engine.create_process(HRSSA,itemkey,hr_sit_jsp_prc,null,sysadmin) and wf_engine.start_process.

my problem is how to send parameters (person_id and others information) to this workflow to get the approvers.

the other informations are segment1,2 and 3.

thanks a lot
