Order Information Portal Implementation help

Hi,

We're using release 12.1.3 of Oracle eBusiness suite.

We have a requirement to implement Order Information Portal. I reviewed the steps in Implementaion guide and looks simple but what I'm looking for is more details on Order Information Portal like

1. What can/cannot be done using OIP

2. Important points to be considered while implementing OIP

3. White papers on OIP

4. I see a lot of scope for personalizations on OIP but want to know how big is the deal of adding some new search criteria

Thanks,

Ram
