I have a table that I want to reverse the values of each of the numeric fields. I want to use a Loop At I_TABLE assigning <fs>. Then within that structure I want to calculate the inverse of each of the fields in the internal table containing the appropriate field names. Here is my sample code:
*Loop at each record in internal table...
LOOP AT DATA_PACKAGE assigning <DP>.
Loop at table with numeric field names
LOOP AT I_DD03L INTO WA_DD03L.
MOVE WA_DD03L-FIELDNAME TO FNAME.
ASSIGN (FNAME) TO <F>.
Reverse each numeric field in <DP>
<DP>-<F> = <DP>-<F> * (-1).
I get an error that states <DP>-<F> does not exist.
