User Exit

Hi All,

Need your help..

Have a requirement like few sales organizations (VBAK-VKORG) exists in my code..for those VKORG's we have to supress usage fields means when running VA01 transaction without usage fields(VBAK-ABRVW) also sales order should be saved..

Do we have any user exit (EXIT) for this ..? and how to code this..?
