Va01-netwr control

Question

I want to control "amount "  field of  item of va01.
if amount >10000 ,  I'll give a error message according  to item of va01.
I used mv45afzz and  userexit_pricing_prepare_tkomp
But vbap-netwr doesn't   change.it has same value.
how can I control this field.

Answer 1

if you're looking for an item/amount that changed, in much of MV45AFZZ, the changed item will be in XVBAP, the old version of the item YVBAP.  At least that's how SD was done when I was writing code for SD exits.  XVBAP-UPDKZ will indicate Insert, Update or Delete for each XVBAP row. In a subroutine that pertains to VBAP, you could do something like:
loop at XVBAP where UPDKZ eq 'I' or updkz eq 'U'.
  read table YVBAP with key posnr = xvbap-posnr.
   if sy-subrc ne 0.  " this is an insert...new item
      if Xvbap-netwr > 1000.
* error message.
   endif.
elseif XVBAP-NETWR > YVBAP-netwr and
          XVBAP-NETWR > 1000.  "this is an update with a price increase...
*error message.
endif.
endloop.
