When we are attaching a report(PDF) in email, the attachment takes a name like 'jobrpt_ReportCode_UserCode_Number'. Is it possible to change the default naming style to change a name which could be meaningful. E.g. If Purchase Order, attachment should be referenced by PO Number. I have used workflow action like APRINT. I wanted to also know that when we are sending such email, it possible to get some context information of the Purchase Order, etc.
