This function enables you to aggregate values for specified format tree nodes (called aggregation nodes) and it makes this number available to a defined field in the DME file.
The aggregation function can be used at the end of a level or a file to:
In this case, you can only specify aggregation nodes that are filled with values (elements).
This could be the amount of all payments in a level.
You can also specify that the absolute values are to be added, which means that the system ignores the + and - signs.
In this case, you can specify any aggregation nodes because the system totals the number of occurrences, not specific values.
This could be the number of payments in a level.
You can define an aggregation for elements or atoms. When you create either of these nodes, select the mapping procedure Aggregation. On the Aggregation tab, you enter the reference IDs of the nodes you wish to aggregate and the aggregation type – how the aggregation nodes are to be totaled to the target node (either summation of values or of total number of occurrences).
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:
