300+ TOP PeopleCode Interview Questions [UPDATED]

1. What Are Classes In Peoplecode?

• SetId is the highest level key in the PeopleSoft. Location, Department and Jobcode tables are control tables and setid’s control the control tables during the transaction.
• Table set sharing is a place where control tables are listed. It is accessed by business unit.

EX: If we have two locations Arizona and Ohio with setid’s xyz and abc,
suppose if we change Ohio’s setid to xyz then we can access all information related to Arizona/xyz like jobcodes etc.

3. What Is Auto Update In Peoplesoft?

It is n-tier architecture. We have client, web server, application server and Database server. We have jolt and tuxedo. We have WSL, WSH, JSL, JSH, QUEUES and services. In database server we have system tables, peopletools tables and application tables.

35. How Can A Component Have More Than One Search Record? Give A Situation?

You might want to reuse the same component multiple times with different search records. You can accomplish this by overriding the component search record at run-time when the component is opened from a menu item without creating separate copies of the component.

The component override is temporary, and occurs only when the component is opened from the menu item in which the override is set. It does not change the component definition.
