Remove permissions to add files
I have the following problem:
A user has read and edit permissions to a record during a phase of a process and during this phase, he can also add attachments.
When the status of this record changes, the same user no longer has permission to edit the record and must also no longer have permission to add attachments to it.
My question is, is it possible to remove the permission to create/add attachments from a certain stage of the process?
