recognition of prior learning

the first step of skilled migration in australia is to have your skills recognized by their governing body.  since im an sap-abap developer, i should apply for it in ACS.  i started my application last month and after a lot of revision requests from them, they now want me to go thru rpl!  rpl or recognition of prior learning they say is a document that you have to provide stating what you have learned from your working experience that is within the key areas of knowledge.  it is supposed to be the route for those tertiary education that is not related to their work experience.  i dont get it because im a comp sci graduate and im working as a developer! argh!!! i so hate ACS right now.
