To create shared members of different generations by using the level references build method, ensure that primary and secondary roll-ups are specified in one record. You can specify as many secondary roll-ups as you want, as long as they are all in one record.

For example, to share the products 100-20, 200-20, and 300-20 with a parent called Diet and two parents called TBC and Grandma’s, use the sample data file and the rules file shown in Figure 96, Sample Rules File: Members Shared at Different Generations Using Level References:
