Enable Attachment in Dataverse
We might want to allow users the ability to upload files and save with a row in a table. Dataverse tables allow users to add an attachment by turning on the attachment property that is associated with that table. If we want to let users upload one or more files into a row within a table, use the following procedure.
Step 1: Sign in to Power Apps.
Step 2: Select Tables on the menus on the left-hand pane.
Step 3: Select a table and click on the Properties at the top.
Or Click on the table and in Table properties select Properties.
Step 4: In Edit table pane at the bottom, select the Enable Attachments check box.
Step 5: Select Save to save the changes.
Note: We cannot undo the addition of attachments to a table. The option will be disabled.
If we again check the properties of the table, now the Enable attachments checkbox is disabled.
