GATP DIalogue user language

Hi

We are using GATP and have the R/3 system set up in numerous languages like CHinese, German, Hebrew etc. When the call for ATP is made to SCM and the result screen is displayed it is normally displayed in english language. How do i make settings to enable the screen display to be in the language of logon in R/3 system?

I hope i was clear with my question.

Thank You
