Aggregation Keys
The GT-Connector always aggregates as tightly as the target data allows by default. Each record will always be unique across all target fields without an aggregation strategy.
By default, only Amount and Quantity have an aggregation strategy assigned (SUM)).
Aggregation keys are a list of Source Fields that allow manipulating the aggregation by differentiating records that would otherwise be identical. They essentially add an additional field to your data that is not sent but only used for the aggregation.
To tighten the aggregation, conditional mappings and/or aggregation strategies have to be used, manipulating values many-to-one. For example, mapping the Invoice Item Charge ID with the condition for Invoice Item Charges to be of type Tax ensures that we have at least one line per tax invoice item charge.. This allows you to configure any logically possible way to aggregate.
