Use the Lightweight Lists utility to report on rules in your application that are using page lists where they could use lightweight lists instead. You can improve system performance by using lightweight lists. The utility searches List views and Summary views, plus Obj-Browse and Lookuplist activities.
The form displays a tab for each type of rule and displays a list of instances where lightweight lists can be used. You can click a link to access each instance, check the Use Lightweight List check box, and save the rule. For Lookup lists rules, enter true in the useLightweightList field.
Caution: Before enabling lightweight list usage for your rule or activity, consider the processing performed by your current page list. If it utilizes features such as forward chaining declarative processing, messaging, value vetting, or other features not supported by lightweight lists, you may prefer to leave the setting as is. For more information, see PDN article About lightweight lists (section "Limitations").
Two dynamic system settings control the use of lightweight lists by List view and Summary view rules and Obj-Browse and Lookuplist activities. There is a setting each for Pega 7 and application rules:
When true, these dynamic system settings override any rule-specific settings you may change after finding them with this utility. For example, if the system setting is set to true, deselecting the Use Lightweight List check box for an individual rule will have no effect; lightweight list processing will be performed for that and all other rules using the lightweight list option.
When either dynamic system setting is set to false, the system honors the setting for each rule and either uses or does not use lightweight list processing according to the setting on the rule form.
The List Views tab displays list view rules in the application defined without the Use Lightweight List check box selected.
