Hi Archit,
you can write small validation it will work
we have to maintain the set for dates as below which date onwards system should allow the posting.
table : bkpf filed budat
from 31.01.2014 i.e which date onwards system should allow. to data will be 31.03.9999
use validation as below
pre check :
BKPF-BUKRS = 'IN08'
check :
BKPF-BUDAT IN ZPOST
mess : Posting Date not allowed for date &
check it it wil work.
Regards,
Raman
