                                        SdaiEntity        entityId,

Returns a numeric attributeID that uniquely identifies an attribute definition instance in the remote EDMdatabase. The attribute is specified by the entityID that identify the entity definition instance in the EDMdatabase, and the attribute name. If the attribute name is not unique within the entity, it must be qualified by the name of the entity from which it is inherited. The returned attributeID will not change throughout the lifetime of its attribute definition instance in the EDMdatabase . It may be used to identify the attribute in subsequent EDMinterface operations.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiEntity	entityId	A numeric entityID that uniquely identifies the actual entity definition instance in the remote EDMdatabase. This is the entity that defines the attribute._
SdaiString	attributeName	The name of the attribute for which to retrieve the attributeId.
SdaiAttr	attributeId	Variable that will receive the returned attribute Id.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value
