Table 92 Selection settings for module Occurrence patterns.
Name	Type	Description
Occurrence patterns tier	Occurrence patterns tier	Specifies the module settings should be set according to a pre-defined tier or using custom settings.
Associate the unspecified percentage with no-occurrence for foods with at least one specified occurrence pattern	Boolean	If checked, for foods with at least one specified occurrence pattern, unspecified occurrence patterns for the same food are assumed to be associated with no use. If unchecked, all substances are considered to be authorised (potentially present in samples). Note that this setting cannot be used for foods that have no specified AUs. These foods have 100% potential presence of all substances. To declare all AUs on such a food un-authorised, include an empty AU with percentage 100% in the AU data table (i.e., use an AU for this food, without specifying substances in the AU Substances table)
Apply occurrence pattern percentages	Boolean	If checked, use the percentages of potential presence as specified by the occurrence patterns. If unchecked, 100% potential presence in samples is assumed for all substances identified by the occurrence patterns.
Scale up use frequency to 100%	Boolean	Scale up use frequency to 100%.
Restrict use percentage up-scaling to authorised uses	Boolean	Restrict use percentage up-scaling to authorised uses.
