We have a very specific problem regarding the handling of attachments in the SRM portal. The feature is activated and we are storing our documents on a remote content server.
However what we would like to do is restrict the access to attachments even though the user has access to the business object. For example one user would have access to say a purchase order and would see that there are 5 attachments attached. Another user with less authorization would have access to the same purchase order and would see only see only three attachments. (preferably this last user would only see the attachments that she or he has uploaded themselves and not that of others.
Does anyone have any idea if and how this could be done on the SRM portal?
