The indents were lost in the cut and paste, its a script that's been in use for over a year. The script is provided to answer the earlier question of how I create a view, which is successfully done. The issue is more about how a view of a feature layer is hobbled in the ability to save to disk when compared to the direct feature layer. BWang, if you provide me an ArcGIS Online username I can add you to a group so you can see it firsthand. ... View more

Here's the Python script I use to create the view.  Note that the source feature layer shows in my content as a "Feature Layer (hosted)", whereas the View shows as a "Feature Layer (Hosted, View) from arcgis import GIS from arcgis.features import FeatureLayerCollection print("started") import json import os import csv view_name = "ParcelAtlas Features V2.4 - Example View" firstFIPS = "18069" # Login to the GIS gis = GIS("https://www.arcgis.com", "chuckb", "xxxxxxxxxx") # delete view if exists items = '' gis.content.search(query = view_name) if items: view_exists = gis.content.get(items[0].itemid) print("view deleted: " + str(items[0].itemid)) view_exists.delete() #This is the feature layer we are creating a view into source_fl_id = '33518827e9e24defbacd671bfdXXXXX' src_item = gis.content.get(source_fl_id) source_fl = FeatureLayerCollection.fromitem(src_item) # Create View from Source Hosted Feature Layer new_view = source_fl.manager.create_view(name=view_name) # Search for newly created View view_search = gis.content.search(view_name)[0] view_flc = FeatureLayerCollection.fromitem(view_search) # The viewDefinitionQuery property appears under layers view_layer = view_flc.layers[0] #Now open a txt file that has all the counties (FIPS) we want to incljude in the view f = open(r'C:\\PA_Work_Folder\\'+view_name+'.txt') csv_f = csv.reader(f) #scan all FIPS and build string FIPS = "FIPS IN (" for row in csv_f: #print(row[0]) if row[0] == firstFIPS: FIPS = FIPS + firstFIPS else: FIPS = FIPS + ", " + row[0] FIPS = FIPS + ")" print(FIPS) view_def = {"viewDefinitionQuery" : str(FIPS)} # Update the definition to include the view definition query view_layer.manager.update_definition(view_def) print ("done")   ...

Thanks Dan. When I run that I get a "Failed to load a resource" error, which is common for this layer, which is 600GB (at one point the largest ever in ArcGIS Online). Esri's had a support case open on this since July and made no progress. To work around, with a regular feature layer I do the selection and then isolate the selection into a standalone layer, which then allows me to save it to disk. It appears that a view doesn't allow the conversion to a standalone layer. I've attached 2 screenshots, one showing the "Make Layer from selected features" option I get when accessing a feature layer, and the other the lack of that option when accessing the same feature layer via a view. Any suggestions are most welcome! Chuck ... View more

Richard, Thanks for the insights.  This is coming from a shapefile that was used to create the feature layer I'm working with. I have escalated this to an ESRI support request, still getting things sorted out. Chuck ... View more

I've escalated this to a formal ESRI support request.  I'll post the results!  ... View more

It has worked on smaller datasets in the past.  However, I just tried it with this dataset and it did not work.  I was able to limit the search to a previous selection that was bounded by a rectangle, giving a fast processing time.  However, I also change the test to "STATE"="MA", which should return all the parcels in the previous selection, and I get nothing.  So I suspect its a more fundamental issue.   This content is coming in from AGOL, whereas before it came from a standalone ArcGIS Server.  I'm starting to wonder if that's part of the issue here. I'm thinking I need to focus on the "STATE"="MA" issue first, before chasing the text vs. int issue. All that said... I do see everything I should when I do an identify... ... View more

In the other thread it was suggested I use "Select from Current Selection", which makes sense.  In this case, I've substituted "SUBSET_SELECTION" for "NEW_SELECTION", and made a rectangular selection of a small area before running the script.  Same sort of delay, but I didn't see the Code 504 error. ...
