Attachement linked to purchase order

Question

I want to know where the attachements linked to purchase order are getting stored in SAP.Since the attachement are linked to purchase order(header level) ,is it possible to link those attachements at item level so when we select a particular item  and  if the attachement exist for that item then we should be able to navigate to that attachement.These attachement are uploaded from window(any text file).Is it possible to implement this functionality at item level(table control) in purchase order?is there any existing functionality which support this requirement?

You can also attach manually any document to PO without using Document Management System ( DMS ) in SAP 4.6C.
But you cannot attach document while you create PO in T/Code ME21N 
Save you PO ( ME21N ) and again open with change ( ME22N ) then you can attach document through Service for Object button. Service for Object button available down side of Command screen ( in your PO screen ME22N ) 
Click your Service Object button -> Create -> Create attachment 
then select your window directory ( which file you need to attach) select your file Now your system shows message  Service "Create attachment" is started. 
Save again your PO. You can see (open) your attachment in same field ( Service for Object ) select and Create and check attachment list. You can attach as many document in your PO.
Note: This is only information for internal or you can print separately this document for sending to vendor ( fax ) System will not print automatically along PO print out.
