I also keep having this problem and found a way to fix it. I also started with a point feature class, a related table to the point feature class, and an attachment table related to the first table. I used an Esri Guid field with the same name in all the tables for the relationships. The service published fine from ArcMap, but when I went to ArcGIS Online and looked at the JSON for each (point, table, attachment table), the point and first table (which had attachments disabled) both showed the supportsApplyEditsWithGlobalIds as true but the attachment table (attachments enabled) showed supportsApplyEditsWithGlobalIds as false. What I did was to disable the attachments from the attachment table and then re-enabled it. When I checked the JSON again it showed supportsApplyEditsWithGlobalIds as true. I was then able to create a survey with Survey123 Connect for ArcGIS using the published Feature Service in ArcGIS Online. I have no clue why this worked, but it did.  ... View more

Thank you Jon, this is a great example.   Just to go a step further, another way to normalize the data might be by looking at the number of pipe feet needed for drilling. So many rigs over so many feet of pipe. Or maybe the inverse, the number of pipe feet per the number of rigs. There are multiple ways to normalize data, not just dividing by area. It once again boils down to what it is you want to show or try to explain. ... View more

Bryan, You say your data shows the "change in number of trees per county", that means this data is not a single total but a rate and is already normalized by county. The word "per" means "for each" (used to express a ratio or rate). So if the "change" is 32 trees per county then the rate is (32 trees)/(1 county), i.e., a fraction whose numerator is a count of trees and denominator is a count of county's. If you want to normalize by area, then the numerator would still be the physical count of trees, but now the denominator would be the area in whatever units you want to use (square feet, square miles, acres, whatever). Just make sure that each denominator has the same units. If county A has 235 acres then county B must also be converted to acres to normalize the data.  Hope this makes sense. If not I would be more than happy to try and re-explain.  ... View more
