An event history is a coded effective date array field, where each row in the array contains a date and a code indicating what happened on that date (e.g. hire, leave of absence, termination). Often, the provided event history includes employment events that don't change how service or salary is calculated (e.g., marriage, divorce, a new child, transfers to other locations/jobs).

To make event processing simpler and easier for you to review calculation results, you can adjust or cleanup the event history, removing all unnecessary rows. If you need to use the event history in an expression, then it's almost mandatory to clean it up (and add the final termination event, if appropriate) to make the expression simpler and easier to understand.

Note, even if you haven't been provided with an "event history", you must be using date of hire and decrement date to calculate service/salary. ProAdmin considers those to be events, too.
