You can use your own include list to choose which TRUEs are to be captured.
An include list contains names of the TRUEs and names of the products, which issue these TRUEs. The Collector collects data for these pairs of TRUE and corresponding product names.
CICS® IA supplies a sample TRUE include list. The name of the default list is CIUXITTB, it contains the pairs of TRUE names and names of the products about which you normally want to collect information.
