Virtual Business Components

---

Business components based on external data are called virtual business components. Virtual business components are used when the business component has to obtain data from a location other than a database table in the Siebel database, but the information has to be presented in the standard Siebel user interface (applets and views). This is typically real-time information from another database, such as from the Report Encyclopedia in Actuate, or from an SAP table, although anything that can supply data in response to a SQL query is a candidate.

Virtual business components allow you to:

• Represent external data (for example, data in an SAP R/3 database) as a virtual business component within a Siebel application—the business component configuration specifies the DLL to use to access the data
• Use business services to transfer data

Virtual business components support properties such as:

• Single-value fields
• Field-level validation
• Standard business component event model (for example, PreNewRecord, PreDelete, and so on)
• Insert, delete, query, and update operations

Additional information about virtual business components:

• Applets can be based on virtual business components.
• Virtual business components can be accessed through object interfaces.
• All business component events are available for scripting.
• Virtual business components cannot be docked.
• Virtual business components can be used as stand-alone or children business components in a business object.
• Virtual business components support dynamic applet toggles. For more information about applet toggles, see Applet Toggles.
• Virtual business components can function as parent member of Link objects in 1:M relationships with standard business components.
  • Virtual business components generate Siebel row IDs the same way as standard business components.
  • M:M relationships involving virtual business components are not supported.
  • M:M relationships in an external system (for example, SAP) that function similarly to a 1:M relationship are supported.
