The date and time on which the Route should be completed is stored in the Next Date field of the Route and is calculated automatically according to the defined schedule. For example, if you specified that the Route should be completed every 4 hours, and should not adjust for Daylight Saving Time:
- The schedule might be defined to be due every 4 hours beginning on May 2, 2012, at 11:00 A.M.
- The Next Date value would be May 2, 2012, at 03:00 P.M.
As you can see, these times are separated by a 4 hour increment, which is in accordance with the defined schedule.
After you upload a Route from a device to GE Digital APM:
- The Last Date field in the Route is updated to reflect the date and time at which the Route status was changed to Finished.
- The Next Date field in the Route is updated based on the values in the Schedule field.
Note: If a Route is completed before it is due (i.e., prior to the date and time in the Next Date field), when you upload the Route to GE Digital APM, the Last Date and Next Date fields in the Route will not be updated.
Continuing with the previous example, if you marked the Route done on May 2, 2012, at 03:30 P.M. and uploaded the Route on May 2, 2012, at 03:45 P.M:
- The Last Date value in the Route would be May 2, 2012 03:30 P.M, which is the time that you marked the Route done. When the Route is marked done and uploaded from the device to GE Digital APM, the Route History status will be updated to Finished.
- The Next Date value in the Route would be May 2, 2012 07:00 P.M. This value is updated according to the defined schedule (i.e., due every 4 hours beginning on May 2, 2012, at 11:00 A.M.) and not according to the Last Date value.
Note: You can also define a schedule in which the next date that a Route should be completed is a certain amount of time after the Route was last completed. With this type of schedule, the Last Date value would be used to determine the Next Date value. For example, if the defined schedule in this example was due 4 hours after last occurrence, the Next Date value would be May 2, 2012 07:30 P.M. (i.e., 4 hours after the date and time in the Last Date field).
