Hi,
i am modifying a internal table in which i am using this statement :-
MODIFY T_DD FROM W_DD INDEX SY-TABIX
and the work area is further used to insert the data base table . i just want to know that is this the correct way to modify the internal table bcoz when i execute the program for updating the database it is hardly taking 1 minute to get updated and i think the problem lies in the above statement.
Please provide me guidelines to sove this problem.
