Middleware (CRM-MW)

Container of business data that belongs together, for example customer, contact person, order or activity. This means that it contains all required information for a business process. The technical representation of a BDoc type is completely independent. There are many possible representations for a BDoc type.

For example, a BDoc type can be represented as follows:

• as a collection of internal ABAP table structures (on the CRM Server),
• by ADO record sets (on mobile clients),
• as an XML form (for non-SAP systems), or,
• as an IDoc.

Therefore a BDoc type is a semantic collection of business data and not a syntactical description.

There are three classes of BDoc types:

• BDoc types exclusively used for mobile applications

They consist of a hierarchical data segment structure with assignment to database tables.

• BDoc types for synchronization between the consolidated database in the CRM Server and mobile applications

They consist of a hierarchical segment structure with assignment to database tables.

• BDoc types exclusively used for non-mobile applications

They consist of:

• a hierarchical segment structure with no assignment to database tables,
• additional data (complex data type modeled in the ABAP Dictionary)

Standard BDoc types are provided by SAP. Additional BDoc types can be modeled by customers.
