Hi experts,
I have 3 input parameter fields.
PARAMETERS:
a TYPE i.
b TYPE i.
c TYPE i VALUE 0.
as soon as i enter values in fields a and b fields, the sum of a and b should be stored in c field.
Example:
when i enter 1 in field a, c should be 1.
when i enter one more digit, say 3 in field 'a' (value in a will be 13) then c should contain 13.
again when i enter 2 in field b, c should contain 15.
Please help me how can i do this???
