How to delete Custom fields without developer in Dynamics 365?

In this post, I talked about custom fields and how to create it

Take care from delete custom fields, because you will lose your data and no return back

In Dynamics 365, you can not insert fields from GUI like userinfo table

and you will get this message if you try to insert fields

you can delete custom fields from custom fields form

System administration/setup/custom fields

 by default, no table select in this form, so just select your table that you need

for example, I create fields in Custtable and I will delete this fields

you can edit your field as the below

(change lenrgt , description , enable and disable for entities ..etc)

Click Delete

click yes to confirm delete your field with the associated data

Thanks.
