/* ============================================================
   Patch prenotazione Picking List a livello documento

   Obiettivo:
   - rendere esclusiva la prenotazione di una sola picking list
   - mantenere la stored con lo stesso nome:
       dbo.sp_xExePackingListPallet
   - introdurre una sorgente di verità per documento prenotato:
       dbo.PickingListReservation
   - far leggere XMag_ViewPackingList.IDStato da tale stato
     e non più soltanto da Celle.IDStato
