Refresh field Descriptions from Datasource function

The idea is to have a function in Pro / Python to refresh the field descriptions for a layer.

Function on a layer: Refresh fields from datasource, this loads all fields from the datasource and replaces the current custom fields description.

The use-case: I need to change the datasource of a layer and I want to refresh the fields information (Names, Aliasses and order etc.). At this moment this option is not available and I have to create a new layer and copy the style, scales, displayname and layrid from the old layer.

Now I have to do this, which is slow on ApplySymbologyFromLayer. I would like to have fast option like: layer.refreshFields()

layer = arcpy.management.MakeFeatureLayer(viewpath, layername)[0] arcpy.management.ApplySymbologyFromLayer(layer, oldlyr, None, "MAINTAIN") layerdef = layer.getDefinition('V2') layerdef.minScale = minScale layerdef.maxScale = maxScale layerdef.serviceLayerID = layerid oldlayerdef = oldlyr.getDefinition('V2') layerdef.featureTable.displayField = oldlayerdef.featureTable.displayField print(f'Displayfield: {layerdef.featureTable.displayField}') layer.setDefinition(layerdef) m.moveLayer(oldlyr, layer, 'AFTER') m.removeLayer(oldlyr) print('Layer Done')
