In the sidebar, click "Administrative documents".

Open the dossier whose filing you want to record.

While the dossier is "In preparation", the regulator expects nothing from you. The buttons at the top only offer the status changes that make sense at this stage.

You file the dossier with the authority through your usual channel; here you record that the filing happened.

The filing date is not a formality: it is what starts the regulatory clocks. Pick the date the dossier was really filed.

The status changes and the available actions change with it: a submitted dossier can be declared complete, corrected, or lapse.

The "Deadlines" tab shows what the filing has just triggered.

You never enter a deadline by hand: OptimCE derives it from the dossier type, the region and the date you have just recorded.

The "Deadlines" tab of the main page gathers the deadlines of every dossier, so you can see at a glance what is coming due.

Every row links back to its dossier and shows the due date. The filter shows the still-open deadlines by default.

Once the obligation is fulfilled, mark the deadline as met. It leaves the open list without disappearing from the record.

Confirm: the deadline moves to "Met" and the open-deadline board empties.

The board shows no open deadline any more. The dossier history still keeps a record of what was done and when.
