Regarding Subtotal text in ALV Grid Display
How to output subtotal text in ALV Grid Display?
If you are looking for specific Subtotal text in ALV Grid, then i think it is not possible.
You can use SORT table to get sub-totals based on the columns that you display.
Generally the record existing on the column based on which you sort the table, appears as the sub-total text automatically.....
You can try giving Subtotal text in the LAYOUT as well and pass the layout to the ALV function module.
