Electric Utility Network Sample Asset Packageでフィールドを追加またはドメインを変更できません

Question

<\/HEAD>こんにちは、<\/P> <\/P> ArcPro 2.5、Electric Utility Network Asset Package 3.3、および SQL Database を使用しています。<\/P> <\/P> Asset Package はサンプルデータで展開され、ポータルに公開されました。現在、フィールドやドメインを追加または変更しようとすると、「このビューに対応するテーブルまたはフィーチャクラスは読み取り専用です」と「このワークスペースのドメインは読み取り専用です」という警告が表示されます。Utility Network を操作する際にこれが正常な動作なのでしょうか？それともアクセスをブロックしている何かがありますか？この件に関するドキュメントや過去の質問が見つからず、メッセージにも理由や説明へのリンクがありません。<\/P> <\/P> 「Add Field」ツールでも試しましたが、エラーが発生しました。下の画像をご覧ください。エラーメッセージはあまり具体的ではありません。<\/P> <\/P> <\/P> <\/P> <\/P><\/BODY><\/HTML>

I have tried to follow what you said Esri suggested here, but my tables still say read only? I stopped both the Feature Service and the Simple Map Service and made a connection to the database as the unowner, and my datasets still say read-only! Any suggestions would be appreciated

Hi Michael,

Thanks for you answer.

You are right, I was using the ElectricNetworkEditor solution when I tried to add the new fields, and this solution works with the Utility Network service. My reasoning was that the ADD FIELD geoprocessing tools would be able to access the database, since the documentation of the tool doesn't indicate otherwise. I think that this tool and the others in the Fields Tools group could benefit from the addition of more details about the source of their inputs.

In the interest of giving more details, this is what I learned from Alex (Esri Technical Support) to be able to add the fields:

* First stop the service for the utility network web layer with the server manager, otherwise the tables in the database will locked.
* Since I had already established the database connection, in the catalog pane, I expanded the Utility Network Dataset and right click on the feature class where I needed to add the fields, then in the pop-up menu I clicked on Design > Fields, to open the fields view.
* Now the fields view didn't show the message that it was "read-only", and I proceeded to add the fields and save the changes.
* Finally, I re-started the web layer service in the server manager. After this, the NetworkEditor map layer reflected the added fields.

In summary, to add, modify or assign: Fields, Domains, Attribute Rules, Contingent Values or Subtypes; the web layer service has to be stop, then make the changes through the database connection.

Thanks.

It looks like you are working with the editor map, which is pointing to the published feature service.  You will need to make a connection to the database to adjust the schema.
