i am calling my above user routine when a user has pressed F8 on a selection screen. clicking on the row of this alv is running a BDC and creating a PO number thru ME27. one of the col of my alv is this PO number.

now my bdc message table is having this number and i hav updated the itab_init[] table.

<b>so for so good.</b>

now ofcourse this alv will not show the po number. so in the end of bdc i am doing:

perform make_alv.

<u>but this is creating another ALV on the top of last ALV. (using back button confirms this behavior, it takes 2 back click to reach to my sel screen)</u>

<b>Experts! suggest a neat way to refresh the ALV.</b>
