Need an user exit or BADI for CJ20n Transaction ,

Dear Friends,

In CJ20N , we have a Structure with Project definition >Top level wbs element >Network Header-->Network Activities

For Network Activity it has main screen with one of the Tab named Necessary Fields. It has a subscreen of Dates having Forecast Start and Forecast Finish Dates(Forecast start Date/ Forecast End date ). The dates format is DD.MM.YYYY. Now we want the Time format 00:00 to be added besides the Date format.

Can anyone suggest if there is any user enhancement (screen exit ) or Badi can be implemented .

Thanks & Regards

Ramakrishna.K
