The Timecard Entry Ul Personal is a hierarchy-type custom setting within Certinia PSA. Hierarchy custom settings are designed to be personalized at different levels: Organization, Profile, and User. The system checks for a setting at the most specific level (User) first, then moves up to Profile, and finally to the Organization default. This allows individual users to have unique configurations for their Timecard Entry user interface, such as their preferred default view (e.g., Day, Week, Month), which overrides any broader settings defined at the profile or organization level.

A. Search Resources Global: This is a List custom setting, not a hierarchy setting. List settings contain static, organization-wide data and do not support user-specific overrides.

C. Assignment Settings: While this is a hierarchy custom setting, it controls core business logic and permissions for assignments. It is managed at the organization or profile level to enforce consistent processes, not for individual user personalization.

1. Certinia PSA Administration Guide, "Custom Settings" section: This guide details the different types of custom settings used in PSA. It specifies that settings with "Personal" in their name, such as TimecardEntryUIPersonal, are hierarchy settings intended for user-level configuration. The guide contrasts this with List settings like SearchResourcesGlobal which are for org-wide data.

2. Salesforce Platform Developer I Documentation, "Custom Settings" module: As Certinia PSA is built on the Salesforce Platform, its use of custom settings adheres to Salesforce standards. The official Salesforce documentation defines hierarchy custom settings as those that "use a built-in hierarchical logic that lets you personalize settings for specific profiles or users." This directly supports why Timecard Entry Ul Personal can be user-specific. (Reference: Salesforce Help & Training, "Custom Settings Overview").

3. Certinia PSA Technical Reference, "PSA Custom Settings Definitions": This technical document lists all custom settings, their API names, and their type (List or Hierarchy). It explicitly classifies pse.TimecardEntryUIPersonal as a Hierarchy setting and ffrr.SearchResourcesGlobal as a List setting, confirming the technical basis for the answer.
