This activity is used to view the calculated due dates for interval based maintenance. At installation, the server process for the calculation of due dates for interval based maintenance is set (by default) to execute daily at 12:00 midnight through a background job. If you have the required permissions, you can adjust the execution time of the background job. For more information on background jobs, refer the activity Using Background Jobs. You can also choose to manually run the due date calculation for a selected serial by using the Perform Due Calculations functionality.
It is recommended to divide the background job into several chunks and run
these chunks in parallel instead of running the background job for each serial
in sequence. This has a great effect on the performance when a large number of
serials are to be calculated. The object properties CHUNK_SIZE and
CHUNKS_IN_PARALLEL can be used to set up the number of serials to process at
once, and how many chunks to process in parallel. For more information on the
object properties, refer the activity
Verify or Adjust
Default Object Properties.
Note: The
background job for the historical average value for operational events should be
completed before the due calculations for interval based maintenance is run. It
would be correct to define these jobs in sequence, or at least verify the setup
before changing any of them. For more information, refer the activity
