SubTotal in ALV GRID

The code below produces alv display with 2 columns: field1 & field2.

field1 is character based & the int. table passed to the alv is sorted on this field.

field2 is numeric, whose subtotals are desired.

so while populating the gt_sort table the option gs_sort-subtot is set for field1 bcoz the subtotals are to be based on the groups existing in this column.whereas the same option is NOT set for field2, even though the subtotal appears in that column.i have marked these 2 statements in the code for your convenience.

execute the code below & you will surely understand what i said above.

bye!!
