# Attachment Control

## Add Attachment Control for a custom entity

The **Attachment Control** is a PCF control in D365 Customer Service. 

This control is set on **Case** forms as default so that you can upload and view attachments. Moreover, you can use this PCF on other entities: **Account** or **Contact**, **but this was not possible for custom entities until now.**

{% hint style="info" %}
Note: You must have at least 1 D365 Customer Service Enterprise or Professional license.
{% endhint %}

Now, I will add the Attachment Control for the **Case** main form

Opening the solution, select the **Case** entity, and open the specific main form. Then select the existing or add a new ***Single Line of Text*** field to the form and add the **Attachment Control** over that field as below. Then Save & Publish the form.

Checking... and the attachment control has been shown on **Case's main form.**

## Security Role - Permission

When I display this control on the form, I encounter a permission issue when I click the button **<+Add attachment>** to attach the file to Case.

**Working around and found some things:**

* Firstly, you must enable security on the Attachment entity in ***Settings> Product > Features***

* Second, you must set permission of entity **"Entity Attachment"** for the Security Role that was assigned to the User.

... and re-checking now

And the entity "Entity Attachment" is not counted in "Dataverse" capacity, this entity is counted in **"File"** capacity.
