Currently (Enterprise/Server 10.7.1), parameter filters (e.g. picklists) for geoprocessing services are fixed at the time of publishing based on the successful ArcGIS Pro tool run being published. It would be good to allow dynamic parameters, for instance by executing the updateParameters() Python toolbox code.
In our case, we want to build the filter/picklist from field values in a geodatabase table, so the code to do this would only need to run as the tool dialog is being initialized, not every time the user changes a parameter.
Thanks!
