I have a hosted feature table on AGO. I want to delete a record from the table. Do I have to delete it from the original excel or csv, then re-upload the file with the append data layer in AGO.
No, you don't have to re-upload the file. Since your file is hosted (feature service), you can add it to a map and then edit the features (add, edit and delete).
Thanks Torbjorn for response. I guess I should have been a little more descriptive. This table is a non-spatial table of vehicle labels that we use in our GeoEvents field Enrichment processer.
