Hi Nagarajun,
I am able to solve this problem.!
All u have to do is follwoing two step.
1.maintained a flag in ur enhacement part (FM to Z_FIND_PO_RELEASE_STRATEGY)
inorder to know whether the current PO is without PR or not then export its value to memory.
2.Do enhancement in standard FM ME_REL_STRATEGIE_EKKO
(which is used to reset release strategy and indicator).
Inside this fm u can find below code
if xchange ne space.
*- Strategie geändert --------------------------------------------------
if e_frgst ne i_frgst or
e_frggr ne i_frggr.
perform reset
using e_frgst e_frggr
e_frgzu e_frgkz e_frgrl.
e_reset = 'X'.
*- Wertänderung prüfen -------------------------------------------------
else.
if t16fb-kzfae eq '4' or
t16fb-kzfae eq '6' .
perform currency_conversion using *cekko-waers
bwkurs_old
hwaers
fwaers
bwkurs
changing *cekko-gnetw.
f1 = *cekko-gnetw * t16fb-tlfae / 1000.
f1 = f1 + *cekko-gnetw.
if cekko-gnetw gt f1.
perform reset
using e_frgst e_frggr
e_frgzu e_frgkz e_frgrl.
e_reset = 'X'.
endif.
endif.
endif.
else.
perform reset
using e_frgst e_frggr
e_frgzu e_frgkz e_frgrl.
endif.....
above code is use to check the PO amount and with old net amount,Since normally code is done to reset indicator only when amount is greater than old one, u can copy above code and modify with ur condition(i.e flag) and paste in last line.
Please check & reward is useful.
