For example, an Accounts Payable module could have segmentation groups named invoices and checks. You select the tables INVOICES_PARENTS and CHECKS_PARENTS as the driving tables for the segmentation groups. Then you associate each table in the module with one of the segmentation groups.

When you designate the driving tables for a segmentation group you must also add business rules and dimension rules to each driving table to determine how the table is segmented. During segmentation, the ILM Engine applies the business rules and dimension rules to each child table of the driving table.

You cannot delete a driving table from a segmentation group if the driving table has any child tables or constraints.

You can find driving table properties in a metadata table named XP_ENTITY_DRIVING_TABLES_EXT.
