To refresh the ALV grid display

Hi,

I have craeted a report which displays the contents of the database table in ALV. on the application toolbar of that alv display, i've given a button to insert new record in that database table by calling a screen to enter new record. when i press that button and enter the details for new record , that record gets saved in database table but its not displaying in the ALV.

i need to press refrsh button manually.

Is there any way to refresh the ALV as soon as i press OK to save the record..

***make sure i m using Grid display.

No object oriented replies please.

Regards

Puja.
