By defining a 'visibilityControllingFlagSourceColumnId' element in the timeSeriesSet, the existence of a flagSource Column for a particular timeseries (step) can be used as a condition for for example a transformation. When the configured flagSourceColumn is not existing for a particular timeseries step, the value will be perceived as 'Missing' for the transformation. All values that did not pass this validation step are removed on read. They are set to missing for equidistant timeseries and removed for non-equidistant timeseries.
This element can also be used to prevent non-validated data to be exportable through a PI-Webservice. If the timeseriesSets in the filterId that is used for the Webservice are configured with a visibilityControllingFlagSourceColumnId, timesteps that do not have the correct validation status will not be exported.
Assign a FlagSource Column per module run
