FPM event Handling

Hi everyone,

I've created a Log on screen in a webdynpro component and integrated that into FPM (GAF Component) as a main step 1. Now I need to validate the screen if the details entered are valid it should move to the next GUIBB that is, next main step 2.

In the log on screen I've written the code for validation at the web dynpro component level. if the details are valid how can trigger the main step 2 ( i.e Next GUIBB ) from the web dynpro component level.

Please Suggest me.

Thank you

Regards,

Nagendra
