CollectionEvents
Provided you have the proper rights you may remove unlinked data sets in
the tables CollectionEvent and CollectionEventSeries. To delete events
which are not linked to any data in the database use the tab page
[Remove unrelated events]. These unrelated data sets may e.g. be
derived from specimens which were transferred to another
CollectionEvent. Click on the [List unrelated events] button to
list all events which are not related to a specimen. The found
CollectionEvents will be listed in the upper part of the form. The lower
part shows the localisations and the event properties related to these
CollectionEvents. These must be deleted first before you can delete the
events related to these data sets. Otherwise only the events with no
relations to localisations or properties will be deleted.
CollectionEventSeries
To delete CollectionEventSeries with no relation to CollectionEvents or
other event series choose the tab page [Remove unrelated event
series]. Click the [List unrelated event series] to list these
series and the [Delete unrelated event series] button to delete
them.
