We have reviewed our DBA item, vendor, and customer listings and for each list, isolated those that we do not need going forward.  The issue is that these item, vendor and customer "do not need" lists fall further into two categories: those which have or are being used (on past or current BOMs, POs, WOs, SOs) and those which never have been used.    
 
Those non-needed numbers/codes which have never been used, we can just delete.  My question is, for the non-needed numbers/codes with past activity, can we somehow de-activate those going forward so there is no chance of those being used?  (I believe the Active status field on inventory items serves no purpose other than as a report filter-inactive items can still be used on BOMs, POs, WOs and SOs ).
 
Thanks-
Mike

If you put a Customer on Credit Hold you will get a warning if you try to enter a SO. Also, you cannot print Packing Slips, or Release items for Invoicing.
