Closing of Open PO

Question

hi guru,
my scenario is
To close the Open POu2019s, the delivery completed indicator has to be flagged in PO-Item detail.
This indicator denotes a closed PO item for which no more GR are expected. But, the system allows to
post GR. There are chances that, the user may use the old PO and post GR.
If delivery completion indicator is set in the PO, the system should throw error message while posting GR.
for this my MM consultant want to write badi or exit, i had writen the following code in the BADI MB_CHECK_LINE_BADI.
BUT its slow down the update processes of the server. nd becoz of this server is not working properly. so what i will do to rectify this prob. if there is exit for this plz tell me.
its showing error  Invalid ROLLBACK WORK in an update function module. AND showing error  ROLLBACK_IN_POSTING in ST22.
DATA: ls_ekpo TYPE ekpo.
DATA: message_var TYPE string.
CLEAR ls_ekpo.
  CALL FUNCTION 'ME_EKPO_SINGLE_READ'
   EXPORTING
    PI_EBELN                  = is_mseg-ebeln
    PI_EBELP                  = is_mseg-ebelp
  PI_BYPASSING_BUFFER       =
  PI_REFRESH_BUFFER         =
   IMPORTING
    PO_EKPO                   = ls_ekpo
  EXCEPTIONS
   NO_RECORDS_FOUND           = 1
   OTHERS                    = 2
  CHECK sy-subrc = 0.
  CHECK ls_ekpo-elikz = 'X'.
CHECK is_mseg-elikz = 'X'.
CHECK is_mseg-bwart = '101' or is_mseg-bwart = '103' or is_mseg-bwart = '105'.
  CONCATENATE 'Delivery Already Completed for' 'Line item:' is_mseg-ebelp '-' 'Material:' is_mseg-matnr INTO message_var.
  MESSAGE e002(sy) WITH message_var.
