Dataview RV_Knowledge_Data_Export currently lists all CMDB_Items linked to a Knowledge Article whether the link is Active or Deleted.  This reduces the value of the dataview.  Not knowing if a listed link is active or deleted is confusing and misleading.  To make the dataview useful you currently need to join the KB_ASSET_LINK table every time (the KB_ASSET_LINK.STATUS field indicates if a link is active or deleted).  Joining a second table every time defeats the purpose of a dataview.  Dataview RV_Knowledge_Data_Export needs a LINK_STATUS field.
