Timesheet records are not created when a large number of records are set to be created.

This issue occurs because Apex heap limits are being reached when a large number of Timesheet records are set to be created.

As a work around, run multiple time configurations separately for different profiles to reduce the likelihood of reaching the Apex heap limits.

Some technicians did not have historical timesheet records created for the previous month. How can the timesheet records be created for these technicians for the prior month or for the period they are missing?

See Retrospective Timesheet Records.

Technicians sometimes add work detail lines many weeks after the related timesheet was created. These time entries are not included in the timesheet via the scheduled timesheet job and Autofill process. Time entry records are not generated even though the Timesheet is present for the user.

Use the manual timesheet pull feature in an SFM configured against the timesheet. This allows manual time entries and updates the daily summary main timesheet with the new entries, even if they fall outside of the Autofill window.
