<Description>
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. |
