The restriction, ObjectExpansion, is available for every major object of Microsoft SQL Server Analysis Services. The client typically uses restrictions to describe the OLAP objects for which the DDL is to be returned, and uses the ObjectExpansion restriction to define the degree of expansion in the returned DDL. The following table indicates whether the enumeration value is allowed for Alter Element (XMLA) commands.

Enumeration Value

Description

ReferenceOnly

Returns only the name/ID/timestamp/state requested for the requested objects and all descendant major objects recursively.

ObjectProperties

ExpandObject

Same as ObjectProperties, but also returns the name, ID, and timestamp for contained major objects.

ExpandFull

Fully expands the requested object recursively to the bottom of every contained object.
