An attribute with the specified name already exists
If you're creating custom entities in Microsoft Dynamics 365, you may encounter an error message that reads "An attribute with the specified name already exists." But why does this happen when creating specific data type fields? In this post, we'll explore the hidden fields that are created using the field name and how they can clash with other fields you're trying to create.
For example, let's say you're trying to create two fields for an entity: "Location" and "Location Name". The issue arises because the system automatically creates a field with the name "location" when the first field is created. This hidden field conflicts with the second field you're trying to create, resulting in the error message mentioned above.
To avoid this issue, it's important to keep in mind the hidden fields that are created by the system. When creating fields, make sure to avoid naming conflicts by using unique names or modifying existing field names. By following these tips, you'll be able to smoothly create custom entities without encountering errors related to hidden fields.
