Maximum "Total weight" LIKP-BTGEW in delivery

Question

The business requirement is as follows u2013 If the Total weight LIKP-BTGEW u2013 in the delivery, at header level - is greater than X kg. Then the user cannot save the delivery (i.e. create a delivery). The user shall get a popup saying u201CDelivery can not be created / saved because the Total weight is greater than X kgu201D
Which program and userexit can I use?
Many thanks, in advance!

Hi
Related with USEREXIT_MOVE_FIELD_TO_LIKP. It's true that this subroutine was designed to provide our own additional fields. If we modify standard field (not advisable), note says:
If standard fields of the structure LIKP are changed, you may have
to carry out determinations and checks that have already been
performed again to avoid data inconsistencies. Therefore, analyze
the dependencies before you change standard fields in the table
LIKP in this exit.
It goes on:
Data from preceding documents should be prioritized and transferred
using the copy control.
so, the solution to solve it in copy rules in my opinion is the proper solution. I'm not sure if LIKP-BTGEW is populated in this moment
So, create your own subroutine (999 for instance) with a coding as this:
FORM bedingung_pruefen_999  USING bp_subrc LIKE sy-subrc.
* Perform all checks as in routine 001
  perform bedingung_pruefen_001 using bp_subrc.
  check bp_subrc = 0.
  IF likp-btgew > your_weight.
    perform message_handling in program (programmname)
                                       using posnr_low
                                         '001'
                                         'E'
                                         'ZVL'
                                         'excess of weight'
                                         space
                                         space
                                         space.
    bp_subrc = 1.
    EXIT.
  ENDIF.
ENDFORM.
where you must create your own message ZVL in SE91 or other.
Other suggestion is set a warning message in copy rules, and set the error message when you save it (think that it could be modify in a future). So use the USEREXIT_SAVE_DOC_BEFORE_PREP
Purpose
This routine can be used for the final change of all delivery data. At the
time of the call, the delivery is complete and consistent; only the
document number has not yet been determined in the creation case and the
final processing of the requirements has not yet taken place. Therefore,
changes to the delivery at this time must be made with particular care
because no subsequent checks can prevent possible data inconsistencies.
Since requirements processing has not yet occurred, this user exit is, in
particular, suitable for changes relevant for requirements when the
delivery is saved.
Remeber to avoid messages during PGI. As it says:
Display of messages
With the output of messages or user dialogs, you must make sure that this
exit can be run both in the dialog and in the background. In particular,
during goods issue posting, messages or user dialogs must never be output
because this may result in incorrect material documents.
