HI,

In simple terms ,

Site means the location of data.

Subscription means the authorization to access to the data

Publication is the data.

We need to define all the above middleware objects in SMOEAC.

You are missing also BDoc and Replication object for the full comprehension. Let's give it a try:

SITE: A destination (with a RFC Queue representing it) which will receive / send data. The data it receives is defined in a -> subscription.

BDOC: The runtime-data container for sending data through the CRM middleware.

Replication Object: Based on a BDoc the replication object is the extension which consists all possible filter objects on a BDoc for distribution possibilities. There is a 1:1 relationship between replication objects and bdocs. (e.g. BP's with filters like > KUNNR, <> KUNNR and = KUNNR and = COUNTRY)

Publication: A stripped-down replication object for actual use. It contains a selection of the possible filter criteria defined for the repl. obj., and all these need to be used in the later -> subscription (e.g. BP's = KUNNR and = COUNTRY)

Subscription: The concrete filtering object based on a publication and having a site assigned (e.g. BP's for R/3, COUNTRY = US, PARTNER = 1231232, PARTNER = 1313232).

Hope this helps,
