Preventing the Deletion of an Attachment in EBS R12

Not sure if this is the right community, especially regarding a Forms Personalization in EBS R12.

Has anyone created a Forms Personalization to prevent the deletion of an Attachments record on a standard EBS R12 Java form, perhaps if the current user is not the user who created the attachment record?

Background:  When our GL user attaches a file to a Journal, we are instructing that user to publish the attachment to the Document Catalog so that it cannot be changed.  But any other GL user who opens that Journal can delete the attachment (i.e. Seq 10) from the Journal, removing it from the journal but not from the Document Catalog.
