The systems does not validate your records when you go though complex processes. It's critical that the system send some validation messages to the user. Examples:

• if you forget location on a equipment, assign it to a PM and create a schedule, the PMS will keep a copy of the equipment information inside the pms table and you will keep it for a long time. If your SLA is based on location, it won't work and you won't know
• if you delete a craft, you loose all the work logs associated to that craft, no messages
• if you forget to create user, employee, craft, the system won't send any messages
• if you delete any record anywhere, you are better to test what's happening on the background table because the system won't let you know.
