ALV GRID - need to display the list of pernrs at a time using the funtional module.

Hi,

can any one help me to get list of record at a time.Not one by one using the select statement.

Requirement:

I have to get the list of record (pernr) at a time to be fetched in the table using the Function module in the end of selection event and it should be exported in alv.

Right now i am getting the single perner,stat2,werks,ansal from tables pa0000, pa0001, pa0002, pa0008 record  and it is stored in the itabfinal by appending from wa_itabfinal. But now i need all the record to be fetched at a time and it should be displayed with out loop.so help me by informing the what functional module is to be used for this to fetch all the records in ALV .
