I know of at least 2 terms that have the acronym SAP.
One is Service Advertising Protocol, implimented in IPX networking for advertising available services within the network.
The other Service access point/port, a term refering to the interface between the layers of the OSI networking model.
Unfortunately neither of these fits the bill and I can't find an explaination for the business term. Anybody got any clues or pointers?

It's something to do with company internetworking. Service Access Provision? Special Apple Pudding? Super Anarchic Pogrom?
