internal table

frnds,

i'm using the table control statements at new, at end of..

but the prob. is that, it considers the fields to the left of the column of the field we use in the condition.

eg.

my itab is .

field F1 F2 F3

_______________________

1st row a1 b1 100

2nd row a2 b1 300

3rd row a3 b2 400

now if i use at new F2, or end of F2, and then SUM, still the values on the right are not added. Coz it considers each value of F1 as a new field.

any other method to sum the values on right, at the change of value of the field F2.
