Show Order Qty, Shipped out Qty, Open Qty for each SCHEDULE line of Orders?

Question

HI Experts,
I need to show the
Order Qty
Shipped Qty
OPEN quantities(Un Shipped quantities)
at each SCHEDULE line level for all Sales orders.
So, am pulling the date like,
Order qty from VBEP-WMENG and
Open Qta from VBBE-OMENG
Then am calculating like,
Shipped Qty =  VBEP-WMENG - VBBE-OMENG
But, still some SCHEDULE lines r missing in VBBE table!!
so, pls. let me know that,
1) Is there any other alternative ideas for my requirement?
2) Why some SCHEDULE lines r missing in VBBE table?
thanq

Try this function module:
  CALL FUNCTION 'RV_SHIPMENT_VIEW'
    EXPORTING
      shipment_number       = tknum
      option_tvtk           = 'X'
      option_ttds           = 'X'
      language              = sy-langu
      option_items          = 'X'
      option_stawn_read     = 'X'
      option_segments       = 'X'
      option_partners       = 'X'
      option_messages       = 'X'
      option_package_dialog = 'X'
      option_flow           = 'X'
      activity              = 'V'
    IMPORTING
      f_vttkvb              = vttkvb
      f_tvtk                = tvtk
      f_tvtkt               = tvtkt
      f_ttds                = ttds
      f_ttdst               = ttdst
    TABLES
      f_vttp                = i_vttpvb
      f_trlk                = i_vtrlk
      f_trlp                = i_vtrlp
      f_vtts                = i_vttsvb
      f_vtsp                = i_vtspvb
    EXCEPTIONS
      not_found             = 1
      delivery_missing      = 3
      OTHERS                = 99.
