Output type Requirement triggering

Question

Hi,
In my project I have a requirement to stop triggering of an output type if all the items in the sales order have reason for rejection set.
I have done the condition check in a output requirement routine and if the condition fails then I set SY-SUBRC = 4.
Problem 1:
But when I am creating the sales order, the komkbv1 structure does not have the sales order no. (it has other fields) and kompbv1structure is not filled. Then how do I check if all the items have Reason for rejection set or not.
Problem 2:
For an existing sales order, I trigger the output type in Header-->Output... , this code is getting executed and sy-subrc is set to 4. But still the output is triggered.
Please let me know how do I proceed.
Code:
w_vbeln = komkbv1-vbeln.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
  EXPORTING
    INPUT         = w_vbeln
IMPORTING
   OUTPUT        = w_vbeln .
Atleast one item of the Sales Order does not have
reason for rejection set.
select single * from VBAP
where vbeln = w_vbeln and
      ABGRU eq space.
if sy-subrc ne 0.
   sy-subrc = 4.
   EXIT.
endif.
Thanks in advance,

Answer 1

Hi,
For the first problem,
  Check the standard structures available, but not sure.
For the Second one,
  You routine include should be included in the standard include RV61BNNN
for it to get triggered.
Your routine will not get executed if your routine is not included in this standard include.
Hope this helps.
