Changing Date Format in ALV List for VKM1 transaction

Hi All,

I have to change date format to MM/DD/YY in the ALV list display of VKM1 transaction. There are user exits available.

I am trying to use EDIT_MASK option of the field catalog.. Without changing the code, I give value as __:__:__ or MM/DD/YY in the EDIT_MASK field of the fieldcatalog during DEBUG. Just before the RESUSE_ALV_LIST_DISPLAY is called.. but it is NOT showing any change in the display.

Please advice any alternate way to do the same.

Thanks a lot.
