Retained inputs
Keep the facts entered for the saved calculation with the record that produced the date.
Professional workflow
Keep a calculation history on the matter
When an eligible result is saved, Professional retains its calculation context in the matter history. A later recalculation can be reviewed beside the earlier record instead of silently overwriting it.

What this gives you
A practical next step after the calculation
Professional retains the inputs, cited rule and calculation working for eligible saved results, so a later recalculation does not erase the earlier record.
Cited working
Retain the rule citation and calculation working that were available when the result was saved.
Earlier versions visible
Keep the earlier record visible when a later calculation or deadline update needs review.
Exportable audit material
Use the available matter exports to create a portable record of the schedule and calculation history.
Clear workflow
Check first. Then choose the right record or workflow.
The paid options follow a completed calculation. They do not replace the check that comes before a date enters a matter or diary.
- 1
Check before saving
Confirm the selected rule, trigger and facts before you ask the server to recompute and save an eligible result.
- 2
Retain the calculation context
The saved result keeps its inputs, citation and working in the matter instead of reducing it to a date alone.
- 3
Review a later change
Compare the later result with the earlier retained record and update the primary diary after review.
What Professional adds
Follow a calculation after it is saved.
Step through the workflow. See the result enter a matter, reach a subscribed calendar and change without erasing the calculation that came before it.

Important boundary
History is evidence of the saved calculation, not proof of compliance
A retained record describes what the system calculated from the saved inputs at that time. It does not establish that the correct rule or facts were selected, that a filing happened, or that a court will accept the date.
