Delete attached files for Transactions and Invoices
According to our discussion in the channel, system lack of deleting attached files. So need to add that feature.
Add a new column 'Delete' after
Attached Byand delete button for each line OR checkbox for each line and delete button beside[Attach]

Should anybody be able to do this? Or should it be restricted? If restricted, should it be subject to review by a second person?
We have a workflow to show the history of the action done on the invoice, right? I think, anyone who can edit the invoice can also edit the attached files.And the workflow history show the action done with the username is enough.
We have a few entries that look like this as well - with multiple attachments because someone uploaded the wrong one the first tiime. As aungzwin says if you have the permission to edit an invoice that same set of permissions should be enough to let you delete an attachement. (Ideally with that noted in the workflow history)
