Hi Venu,
If your Next & Previous records from database table, then you have to fetch the data again on action 'NEXT' & PREVIOUS buttons of alv, for this you have to keep unique field for ex. Item No or any of the number field as per your conditions...
But, In case if fetched 30 records in ALV Internal table,Now You are in 10 - 20 records, if you want to perform previous or next, the interface IF_SALV_WD_TABLE_SETTINGS will take care of, pls check with the method set_visible_rows..etc..
