You can check certain situations such as working time collisions and time account balances in time evaluation. Time evaluation produces messages in addition to a log.
The Message Processing task in the Time Manager’s Workplace is a comprehensive tool for both evaluating messages and reprocessing them.
Messages are viewed and processed by time administrators after time evaluation is run. In this way, time evaluation messages help to evaluate time data recorded. Sometimes all you need is one message to determine what happened for an entire day. In other cases, however, only the appearance of several messages enables you to estimate the entire day.
