How to restrict masterdata changes before rectro active accounting datre
I have a scenario that, system is accepting the masterdata change of any sort, before the retro active accounting date through ESS and CATS. My retro date is 01.08.2010 and now i can see earliest MD change before this date in IT 0003and even change happend in 01.01.2012 also..Is there any BADI to restrict /reject the masterdata change through ESS and CATS? I feel when upload a bulk data ,system is accepting this..
Thanks in advance!
