Material download from R/3 to CRM

Hi Guys

We have a scenario where we are gonna download configurable service products and orders from R/3 to CRM .

We have the IPC up and running .

To download the configurable products :

We have created the Kbase and runtime version in R/3 .

as i understand the steps to be followed are

1) download the material objects from R/3 to CRM ....(what are the possible objects that will cover the entire gamut of material downloads?)

2)Once the necessary material objects are downloaded , we will download the objects OBJCL , CLASS , and SCE .

Am i missing something here ?? Is there any additional things that i need to take care of before proceeding with the steps ??

Any working document on this would be really helpful

Regards

Kris
