Impossible d'ajouter un champ sur la carte Web

FilipposGekas

<\/HEAD>

Bonjour,<\/P>

<\/P>

J'ai créé une carte il y a quelque temps avec ArcGis Online. Le format de la carte était une web map. J'essaie d'ajouter un champ à ma couche, mais il n'y a pas une telle option dans la table de description (Les options de la table ne me fournissent que 4 options, aucune d'elles n'est ajouter un champ, j'ai essayé d'activer\/désactiver l'édition).<\/P>

<\/P>

Des suggestions ?<\/P>

<\/P>

Merci.<\/P>

Cordialement,<\/P>

It looks like your ports layer is a feature collection. In order to add a field to a table, you must use a hosted feature service: Show tables—ArcGIS Online Help | ArcGIS . To publish ports as a hosted feature service, hit save layer in the map viewer, and then navigate to the resulting layer item. A publish window will appear to give you the option to publish as a hosted feature service. (This requires an organization account).

Only the owner of a hosted feature layer or an administrator of the organization is able to make changes to the attribute schema.

Are you one of them?

How To: Add a field to an ArcGIS Online hosted feature service

CarmelConnolly3

How was the layer created? Was it published from a shapefile/file geodatabase or created from Map Notes? Can you find the item in your My Content?

Also, if this layer is a copy of another, you won't be able to add a field to it, only to the original layer.

Dear Jayanta,

Thank you for the answer. I am the creator of the layer, owner and administrator. I have read everything online and cannot find an answer to this!

Best,

Filippos

Dear Carmel,

Thank you for your answer. To be honest I created this map one and half years ago, so it's been a bit blurry to me! I probably created the layer from the web map interface of Arc GIS Online website (I might have done it from Arc Gis Desktop, but I doubt it). I can find the map from my content. This layer is not a copy of another, it is the original.

Best,

Filippos

Hi Filippos,

In the Webmap, click the 3 dots beside the layer name > choose Item Details > can you send a screenshot of what you see? It should look similar to this:

Could you publish a new hosted service (then open it in a new web-map) and check if the issue persists with the new layer as well?

I want to edit Ports but for some reason they are not editable, it appears.

DaveStewart1

I have created and hosted two layers as well. One layer I am able to add a field to (in ArcGIS online) and the other I cannot. I have enabled full editing on both layers. Very perplexing... On the one layer which I cannot add the field to, I used a unique valve (thematic - a simple yes/ no symbology). Could this be the reason why I can't add a field?? Is this a bug? Or human error?

Hi Dave,

Are both layer hosted feature layers or are any layers hosted feature layer views? It isn't possible to add a new field to a hosted feature layer view, but it can be added to the source feature layer and then displayed in the feature layer view. IF this is the case, let me know, if they are both hosted feature layers, I'd suggest getting in contact with support to further investigate this issue.
