To set up an aggregation structureTo carry out aggregation and/or disaggregation, you must first set up aggregation relationships. You can manually define aggregation relationships in the Aggregation Relationships (cprpd3110m000) session. Here you can specify, among other things:
In addition, you can let LN generate aggregation relationships between a specific family item and an entire range of sub-items in the Generate Aggregation Relationships (cprpd3211m000) session. This is a straightforward way to create aggregation relationships, because you can only define general settings that apply to all the relationships that LN generates for the specified range of sub-items. Afterwards, you can fine-tune each of the aggregation relationships that LN generated individually in the Aggregation Relationships (cprpd3110m000) session. Note The way in which LN uses the various aggregation percentages that you define in the Aggregation Relationships (cprpd3110m000) session depends on the value that you specify in the Aggregation Type field:
Note If you want to use planning percentages for disaggregation as well, it is recommended that you define separate aggregation relationships for aggregation and disaggregation. Automatic updating For aggregation and/or disaggregation, you need to set the following fields in the Items - Planning (cprpd1100m000) session to (Dis)aggregate or Always Update (as required):
Special cases of aggregation You can use the Aggregate Channel, Plans & Orders (cprmp2250m000) session and the Disaggregate Channel, Plans & Orders (cprmp2260m000) session to aggregate or disaggregate planning data. However, note the following special cases of aggregation:
