An event is only included in CARDS month-end processing once it has been finalized. The session date is used during the ratings' update (but see below for further details on this point).
When you run the export option at the end of month all the events in the date range selected will be displayed in the list. NOTE this is the event date, not the date of the sessions within the event. The session dates within those events are used during the update process and are used to identify the uniqueness of the sessions of play.
Therefore events with many sessions need to be handled carefully, particularly where it spans the end of month. This can be handled in one of two ways.
(1) Always process an event in the current month.
The event is finalized at the end of the month and exported with all other events for the month. When the next session of the event occurs, open the event and re-set finalization when asked. Proceed with the event as usual. Date the sessions correctly during the next month. It is also possible to change the event date to the start of the new month so that it will appear in the list of finalized events for that month (this is purely for your convenience and is not necessary).
At the end of the second month finalize the event as usual and export this event again. The sessions from the previous month will be ignored during the next update (as they have already been done last month).
Do not change the name of the event as it will be considered a new and different event.
Do not change the dates of sessions previously finalized as they will be considered new and different sessions in the next run.
(2) Only process the event once it has finished.
The event is finalized only when finished. The sessions for the previous month(s) will not appear in the previous month's reporting. This only occrs when the event is finalized. The impact on the player ratings will remain as calculated during the previous month. The players will not see that impact until next month or the month when the event is ultimately finalized.
In the update, the sessions from the previous months will be processed as if they were from this month. It is of no consequence to your reporting or management of your events at the club.
