Need help in developing a sample PO process.

Hi,

Could any one share a sample process development doc which guides step by step development of any process(Eg: Purchase Order Approval).

Plz help me in building the PO process.

Thanks,
Maaz

have you read process engine guide and designer help guide?

Thanks for the response Shahid bhai, Yes i have read Designer help guide and successfully implemented a sample process also.

But i want to implement a real time scenario in which a purchase order doc should be published and the manager should approve it…kind of.

So plz help me in building this scenario (what services i have to write in developer for this scenario?).
