In your dynamic internal tables, does all fields can be summed?
If yes, I would do like this. Create a generic a variable say V_FIELD. Assume maximum program may have 30 fields.
data v_field type char30
data v_num type char2.
data v_field1 type char30.
data v_field30 type char30.
do.
add 1 to v_num.
CONCATENATE 'V_FIELD' v_num into v_field.
assign (v_field) to <fld>."This holds the value of the field. Initially 0.
ASSIGN COMPONENT sy-index OF STRUCTURE <YOUR_DYNAMIC_STURCT> TO <fld_value>.
if sy-subrc = 0.
<fld> = <fld> + <fld_value>.
else.
exit.
endif.
enddo.
As the DO loop process it sums up for each column total into each variable. Once complete data is processed through, add these variable to as new record to internal table.
If all fields are not summed type of field then validate by the on the field type and process the logic
