How to Integrate Workflow and EP Iviews?

Hi,

I want to Integrate workflow with EP Iviews. I think some of you would have done this process before, can some one help me out with some links?

I developed an simple Absence form approval process in workflow. I need to start this workflow from EP web apps and continue the approval process from EP itself by developing the forms to access the Object types and their methods(Create,Update,Approve etc).

I wonder whether someone has accessed the workflow Business workplace inbox from EP Iviews.

There should be some way to do this process.I couldn't find any proper links in SAP websites.

Thanks
