Hi santhosh,
Open the infotype ,
goto->attributes
there you'll find an option to change your development class,if you have already created an development class then find it. others wise copy that infotype to another client and try to save the infotype , it'll ask you the development class name.
(When u create an Infotype, a customizing request has to be created wherein the Infotype Characteristics entries are stored.
The same customizing request needs to be transported too, else the infotype shall not be visible. )
Regards,
Kumar
