FI Service Tax Report.....!

Hi Experts,

I am developing a Service tax report in FI module .I have two radiobuttons (ST Recievables(Vendor), ST Paybles(Customer) ) and one check box (Service tax normal).

I need to fetch the data based on Company Code,Fiscal Year, posting date. So i have developed for ST Receivables Radio button and Service Tax (Normal) selections in Input Screen.

And now i have almost similar logic to ST Paybles and service tax normal check box. So can i have the logic how can i use the same internal table and ,feild catalogue and ALV_GRID_DISPLAY.

Please provide me the logic.

Regards,

Suresh
