Returns a numeric instanceID that uniquely identifies the entity extent of a specified instance type in a specified EDM Model. EDM Models have individual entity extents for all their defined instance types. Optionally, the returned aggregate of instanceIds may include all subtypes of the specified instance type.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiString	remoteRepositoryName	Specifies the name of the repository in the remote EDMdatabase that holds the model of interest. Repository names are case sensitive.
SdaiString	remoteModelName	Specifies the name of the remote model of interest. Model names are case sensitive. The combination of the <remoteRepositoryName> and <remoteModelName> arguments uniquely identifies a model in a remote EDMdatabase
SdaiString	entityName	Specifies the name of the entity. Entity names are case insensitive.
SdaiOptions	options	See description of available options below. Options may be joined by using the bitwise OR operator. Default behaviour is that no subtypes be included in the returned entity extent.
SdaiAggr	aggrId	A variable that will receive an aggregateId that contains all instances of the given instance type, and optionally all instances of its subtypes.
SdaiInteger	instances	A variable that will receive the number of instances that was returned in the parameter <aggrId>.
SdaiInteger	subtypeInstances	A variable that will receive the total number of instances in the entire population of the EDM Model. This number includes all instance types.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value

Error rendering macro 'excerpt-include' : User 'null' does not have permission to view the page 'US:_r_EDMInterface'.

Options

Option	Comment
SUBTYPES	Include all subtypes of the instance type specified by <entityId> in the returned aggregate of instanceIds.
