Hoe update je gehoste feature layers correct?

Question

<\/HEAD>Ik probeer een gehoste feature layer bij te werken via een zipbestand met gewijzigde shape-bestanden. Hoewel de update correct wordt uitgevoerd, is het resultaat dat de features gewoon worden gedupliceerd in plaats van daadwerkelijk te worden aangepast? <\/P> <\/P> Heb je suggesties waarom dit gebeurt? In wezen wil ik één gehoste feature layer die ik vaak kan bijwerken zonder elke keer nieuwe feature layers te hoeven genereren en uploaden.<\/P><\/BODY><\/HTML>

Hello Ben,

Could you provide some more information as to the workflow you're using? Are you going to the Item Details page of your data and clicking Append? If yes, this process looks for a unique identifier field and uses that to identify data that needs to be overwritten vs. added as new features.

The following page has a run-down of this workflow:

Manage hosted feature layers—ArcGIS Online Help | ArcGIS

You can set one of your fields as a Unique Identifier by going to the Data page (top right of the Item Details page), then going to Fields in the top right, selecting the field in question, and changing the Field Value Type to Unique Identifier. Then try appending again and it should overwrite matching unique identifier features.

Let me know if I need to clarify more, not sure if that's clear. Thanks!

Best regards,

Rachel
