Dynamic output & input fields

HI Guru,

I have a requirement in which a list of radio button

with the fields names for output as well as input appears. Based on the tick, the report first should display the input fields with selection-option and

also display outputfields based on earlier ticked.

Its similar to se11 in which we can choose input fields

and also decide on output fields.

Could anybody let me know any functions.

Regards,
