The action button element is a great tool for efficient record creation. The action button allows the entity in which we are looking at to copy data from the to the new entity.
Action buttons exist on entities across the system where the buttons in each entity (record type) allow you to create a new record of another entity using the related data from the current record.
Predefined procedures ensure that the filled-in values of the related fields are copied to the new record so that we do not have to re-enter the same data more than once.
