Yeah you can do that with the help of REUSE_ALV_GRID_DISPLAY FM in th module pool.

Check following links -

<a href="http://www.erpgenie.com/sap/abap/controls/alvgrid.htm">http://www.erpgenie.com/sap/abap/controls/alvgrid.htm</a>

<a href="http://www.sapdevelopment.co.uk/reporting/alv/alvgrid_enhanced.htm">http://www.sapdevelopment.co.uk/reporting/alv/alvgrid_enhanced.htm</a>

If you want to do it using OO method try BCALV_* in SE38 for examples.

Hi Pabitra,

For ALV in Module pool you have to use Class. For Complete Details of ALV you can visit...

http://help.sap.com/saphelp_erp2005vp/helpdata/en/99/49b844d61911d2b469006094192fe3/frameset.htm

Main things about ALV in module pool is it's different than ALV using FM.

Here are steps to do so...

1. Creating a control and integrating it into the screen

2. Passing methods from the backend to the frontend

3. Handling events triggered by the control at the frontend

4. Destroying the control (Lifetime Management)

Hope this will help... For more information... Please write back...I will be more than happy to help.

Only condition is u have to reward points
