Hello,

You have created a thread on this already.
https://community.dynamics.com/forums/thread/details/?threadid=ef802608-4a77-ef11-a670-7c1e521b3ced

How do you define it as created manually and not through extension?

Can you show us the page inspection panel on the item card page with the custom field? An example below.

Hello,

I am not getting any option to reply to the answers mentioned below, so I had to reply here.

here is the page inspection panel on the item card page with the custom field that is Box Length

I just want to fetch Box Length, Box Width, Box Height values

here I am sharing the all three fields present in the item table

I would appreciate it if you could provide a solution to help me achieve this.

Thanks!

Hello,

From the provided page inspection, the field came from the app/extension,

As posted earlier, you need to add the app as a dependency in your app.json.

You can find these informations on the 'Extension Management' page.

Then run download symbols in VS code.

in the alpackages folder, you will find the Empowerment Technologies Inc app.

Now, you will be able to reference the field. If the app is there but you are still unable to do so, try closing and reopening the vscode.

If you want to access field by api for item table so you should must add that field using page extension on page,If you does not want show on page so you keep it visible false but it should be on page for api.

If you have field on table and want to show on page then you must create page extension.
