Hi Gurus,

Its a bespoke webdynpro application done by someone in my organisation........There is a date field which is set to default value"01/09/2007".

If the user wants to change the date they can change it according to their need........But if they give wrong date format......they will get error message as "Please, give the value in the form 25/11/1987"........but now they are getting the message in german language.......how to change this to english..........Please help in regards......

Only the message is in German Language other text are in english.............
