This functionality is now available in FEWS.However it is important to understand that this functionality cannot be used in all workflows. The functionality can be applied for transformations only. It cannot be used for running models or secondary validations. When a transformation is started for a location selection than the transformation will only start when the location of one of the input time series is selected or the location of the output time series is selected. When a transformation has created output for a location which was not selected by the user than this location whill be added to the selection.
...
The transformation will run for the selection selected locations. If one the input timeseries is selected in the filters or in the map the transformation will run.
This means that the user should select the locations which are changed. This can be a change in the data or a change in the configuration.
This can be explain explained with the use of a simple example. Lets say we have a system which has a workflow which consists of a user simple function which estimates the water level at location B by simply copying the water level at location A to location B.
After the copying a set of statistical functions statistical transformations are run to compute statistics.
...
remember that location B is now also changed and will add location B to the list of selected locations. When the statistical functions are run statistical transformations are started after the water levels are level at location B is recomputed the statistics for location B are also recalculated because in this case the transformation which recomputed the statistics for location B will be part of the has a input time series for these transformations and with location B and because location B is now was added to the list of selected locations, the statistical transformations which calculates statistics for location B will also be started.
This functionality cannot be used for spatial transformations. Before enabling this option for a workflow, the configurator should check if the workflow contains spatial transformations.
