Hai Kamal,
You can use User exit as per Mr Mozzam suggestion
if you want to use enhancement; use
Include MF02DFEX
if sy-tcode = 'XD01' or sy-tcode = 'XD02' or sy-tcode = 'VD01' or sy-tcode = 'VD02'.
kna1-AUFSD = '01'.
endif.
Whenever their is change made in the customer made, this enhancement will block the customer from sales transaction.
Authorised person should release thro XD05.
Regards,
Mani
