When the user deletes observations they are not deleted from the Application Server but only marked as deleted (as long as deleted observations are not purged). If a view's filter term is based on observations those terms can therefore either be applied to all non deleted observations, to all deleted observations or to both non deleted and deleted observations.
How deleted observations are handled can be set for each view and applies to all view filter terms in that view's filter that filter on the features' observations. Table 1 summarizes the options for this setting.
Option |
Description |
Include only non deleted |
Default. Deleted observations are not used when evaluating filter terms. I.e. a feature is only member of the view if the filter term applies to non deleted observations. |
Include both |
Deleted observations as well as non deleted observations are used when evaluating filter terms. I.e. a feature is member of the view if the filter conditions that filter for observation data applies to deleted or non deleted observations. |
Include only deleted |
Only deleted observations are used when evaluating filter terms. I.e. a feature is only member of the view if the filter conditions that filter for observation data applies to deleted observations. |
