Self Service Requisition with Endeca Layer

Hi All,

This is my first post to the JDE Community, We have a long standing JDE Customer (actually 2 of them) and both have requested a amazon type search on the self service requisition page. i.e. similar to the one available for iProcurement in eBusiness.

We need some technical information i.e. what is the framework of self service procurement built on so that we can then think of adding Endeca Layer to the page. Also I would like to know the API's that are available or are used when we create a requisition using this page.

Kindly help
