DefaultValue Element in DefaultValues (BDCMetadata Schema)

Last modified: July 20, 2011

Applies to: SharePoint Foundation 2013 | SharePoint Server 2013

Represents a default value.

Some methods have complex signatures. For example, the Web service to get CRM customers might take six parameters, three of which might be structures with subparameters. To make it easier for users to call these methods, BDC allows you to specify default values for the parameters in the metadata. This way, users can invoke predefined business logic without having to undertake parameter construction.

The user can override any input parameter for which you have defined a DefaultValue. The user must specify any input parameter that has no DefaultValue, if the parameter is not optional.

For each abstract primitive in a TypeDescriptor object, you can define multiple default values, each of which corresponds to a particular MethodInstance object. At run-time, depending on which MethodInstance object the client executes, a parameter will be instantiated based on the corresponding default values.
