What is the difference between global PeopleCode and component PeopleCode?
Global PeopleCode variables are available during the life of the program that is currently running. Any global PeopleCode variables are saved when an Application Engine program commits and checks points; therefore, they are available in the event of a restart. Component PeopleCode variables act like global variables in Application Engine.
The component level Peoplecode works only for that particular component and if any record in the component is referenced by component level peoplecode then it would not effect any other component where same record is used as it was doing in above case. Sequence: first Record level peoplecode will fire and then Component level peoplecode.
