What does it do?
AQ_Aggregate_Count retrieves the number of found aggregates and stores this in an attribute.
Parameters
Parameter | Direction | Value | Description | Required |
|---|---|---|---|---|
| Aggregate type | Input | Module element Aggregate | Select the aggregate type to count. | Yes |
| Target entity | Output | Entity | Select an entity in which you want to store the aggregate count. If this entity is a multiton, an instance is created for each time this service is invoked. If this entity is a singleton, the aggregate count is overwritten each time this service is invoked. | Yes |

Unauthorized: This exit is triggered when the user does not have one of the roles that is set on the aggregate definition.
Tracing
Counting aggregates is not traced, just like reading aggregates (using Service call type: AQ_Aggregate_Read).
