Arguments

1	Type	Name	Comment
2	SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
3	SdaiAppInstance	currInst	A numeric instanceID that uniquely identifies an instance in the remote EDMdatabase that owns the attribute on which to create the typed aggregate.
4	SdaiString	attributeName	The name of the attribute on which to create a typed aggregate. Attribute names are case insensitive. When the attribute name is not unique within the instance <currInst>, it must be qualified with the name of the entity from which it was originally inherited.
5	SdaiSelect	pSel	Pointer to a locally allocated tSdaiSelect data structure that contains the type specification of the typed aggregate elements. The aggregate is typed with a path of pSel->nTypes elements. The path must be specified in the buffer pointed to by pSel->typeList. Each element in this buffer is a numeric typeID identifying a defined type instance in the remote EDMdatabase . The last specified typeID in the pSel->typeList buffer defines the element type of the typed aggregate.
6	SdaiAggr	aggrId	Variable that will receive the aggregateId that uniquely identifies the typed aggregate in the remote EDMdatabase
7	SdaiInvocationId	edmiInvocationId	Currently not used.
