This could be the number of payments in a level.

Incoming Files

You define an aggregation using a technical node. Assign it a reference ID and set the Aggregation node indicator on the Attributes tab, and enter the reference IDs of the nodes to be aggregated and how they are to be aggregated on the Aggregation tab. The technical node stores the aggregated value, which can then be used to:
