EXIT_SAPLEBND_002 -- user exit for release strategy

Question

Hi,
This is regarding help on user exit for release strategy, ref: note no. 365604, however after going through all the config part given in the given note we activate the fm in cmod.... but after activating the release tab goes off from  me29n.
That is after you activate in cmod and then if u create po and go to me29n the relese tab is not there.
if u deactivate and create po and then relese the release tab in me29 would appear.
All we are trying is that the po in me29n should be open to release again if we change the delivery date. However what coding and how is still a second step , first is as soon as the exit is active the tab goes off.
New to user exit . plz help.

Hi Again,
I guess I have solved the issue temporarily, however Am not sure if this is the best which cld be doen to the issue.
I didnt make any new characteristics in ct04, for the delivery dats since i didn't want to restrict the delivery date. All I did i yje coding below in the exit :
  DATA wa_eket TYPE LINE OF mmpur_beket.
  DATA wa_eket1 TYPE LINE OF mmpur_beket.
  data: c type i.
   data: p type i.
  break1.
  break2.
  e_cekko   = i_cekko.
loop at it_beket into wa_eket . " for comparing previous and the current del date
  e_cekko-usrc1 = wa_eket-eindt.
  SELECT SINGLE * FROM eket INTO wa_eket1 WHERE ebeln = wa_eket-ebeln
  AND ebelp = wa_eket-ebelp.
  if wa_eket1-eindt <> wa_eket-eindt.
  import c from memory id 'CID'.
  c = c + 1.
  clear p.
  p = c mod 2.
  if p is not initial.             " adding 0.01 to the characteristic value for p.o amt.
  e_cekko-GNETW = e_cekko-GNETW + '0.01'.
  else.
  e_cekko-GNETW = e_cekko-GNETW - '0.01'.
  export c to memory id 'CID'.
  endif.
  endif.
  endloop.
The logic I tried using is since the relese gets reset incase of p.o amnt and hence indirectly po amnt so i changed the value of p.o value by 0.01 incase of change in delivery date. cekok-gnetw doesnt reflect anywhere in the p.o as amnt, I guess its for defing range for relese stragey's amont in ct04 characteristics.
However anything better incase u know plz let me know, or do u think this can cause any problems later....new to exits.
Rgds,
Anu.
