CRM Business Document Modeler 
The CRM Business Document Modeler (BDoc Modeler) is a tool used for modeling business document types (BDoc types). The BDoc Modeler allows you to model the following classes of BDoc types:
· Messaging
· Synchronization
· Mobile Application read only and modifiable read
BDoc types describe the structure of the data segments in a BDoc message. Data is encapsulated in BDoc messages that enable you to transfer data between the CRM server and mySAP CRM components.
The BDoc Modeler allows you to:
· Filter BDoc types based on the specified criteria.
· Assign synchronization BDoc types (formerly write BDocs) to a messaging BDoc type.
· Assign site types to messaging and synchronization BDoc types.
· Generate the R/3 structure name automatically for a segment.
· Check a BDoc type for data consistency.
· Track errors by using the Traffic Lights display mechanism.
· Generate R/3 services for a BDoc type.
· Release BDoc types for correct upgrades.
· Transport a BDoc type.
· Track the occurrence of an object by using the Where Used list.
· Specify access rights for users by using the authorization concept.
· Create a copy of BDoc types and segments.
· Toggle between the active and inactive versions of a BDoc type.
· Generate stored procedures for a list of BDoc types.
· Navigate to the data element, table, and structure definitions.
· Map tables to segments and table fields to segment fields automatically by using Direct Map.
· Modify a BDoc type. However, when you modify a BDoc type, the BDoc type is locked. Therefore, only one user can modify a BDoc type at any given point of time.
