PM Schedule Date
PM schedule dates represent the dates that a particular PM Schedule should be run. PM Schedule Date (pmsd) records are generated when you run the scheduling routine, which consults the PM Schedule record and generates the appropriate PM Schedule Date records for the specified time frame and completes these records' PM Date field with the date that the job should be executed. You can edit the generated value if necessary.
PM Schedule Date records always reference a PM schedule (pms) record. A PM Schedule record will have multiple PM Schedule Date records, each representing the date a job should be executed.
When you work with the PM Planner's calendar and expand the groupings, the calendar displays the values from PM Schedule Date records in the left panel.
