English to Chinese Tech/Engineering SAP

Is it all the pieces, really, you may ask. There are two pieces that have separate prices. One is Master Data Management (MDM), which has an engine price, which comes in three volumes. It's like a T-shirt, in small, medium and large, depending on the number of objects you manage in MDM. The second piece is XI engine. You only have to pay for XI engine for integration with SAP and non-SAP. If you're doing integration of SAP to SAP instances, you don't need to pay for the XI engine. That's only if you are doing integration of SAP to non-SAP. But that's an important piece, right? Because most likely a user is going to have a non-SAP application when he buys SAP's application. But we didn't want to tax every user. So we could have brought this XI in, but then we'd have to raise the price for every user.
