Authority check in the report

Hi All ,

I have created a ALV report in that displaying three different reports on three radio buttons.These three reports uses same selection screen except 2-3 fields.

Now our customer wants to create two t-codes for the same report one for first radio button report only and other will have whole report.My query is how I can put a check in the report so that i can check authorization available for that user or not as he will not able to access other two reports.

Please suggest.

Regards,

Sachin
