The SPMS shall enable the user to reschedule a due date before the calculated due date, and record the related reasons.
The SPMS shall provide a forecast for the material resources required for a set future period of time in a range of equipment and systems to be produced, based on the existing maintenance plans.
When a maintenance task is completed, details on the maintenance task shall be reported, at least including:

a) the name of machinery, equipment;
b) the SPMS task and description;
c) the last maintenance date;
d) the next maintenance date;
e) the person in charge.
Supervision over input data shall be exercised through the SPMS, so that a user with supervisor’s permissions can review and manage maintenance reports.
The approval shall be recorded, and the supervisor shall be capable of checking the list of tasks, categorized in terms of approved versus unapproved and planned versus completed.
