Hi Sowmya,
BDOCS: Business Documents are the semantical layer for the whole CRM, regardless of implementation details. A major achievement of a semantical layer is, that the need for point-to-point mappings are eliminated. Using BDocs mean fast integration of applications. The definition of Business Documents (BDoc) does not contain implementation details. It differs depending on the underlying technology, so that the optimal representation of a BDoc can be used:
Implementation examples:
• CRM Server: Internal tables
• Laptops: ADO record sets
• Non-SAP System: XML Decoupling of Messaging
An Intermediate Document (IDoc) is a SAP standard format for data transfer between systems.
IDocs are mainly used for Application Link Enabling (ALE) and for Electronic Data Interchange
(EDI). They are not used for processing inside an application.
Business Documents (BDocs) are used by the CRM Middleware to exchange data with mobile
clients. Furthermore BDocs are the central data structure to process business objects internally.
In contrast to Idocs, for which the internal processing has to be implemented manually, the coding to
process BDoc may be generated automatically.
