Page 2 --> remaining 4items fit

                display the subtotal displayed on the on the previous page as first record of page

                display remaining 4 items

                calculate and display subtotal of field amount(WRBTR) of these 4 items at end of page 2

In last page calculate and display grand total based on the subtotals

In my table i_item (DATA section) i added a footer section and placed the code SUM(I_ITEM.DATA[].WRBTR[]) in the subtotal field, but it gave the grand total.
