I create a module pool to management information about timetables.
In the module pool we have several options like create ,modify and delete records from several tables.We have 3 dynpros than contain ALVS based in OO .In the general screen we can select these alvs ,but when i try to use the alvs again with other parameters ,it show the same data (when i close the alv the first time and reach the general screen i delete the reference to the objects).
¿Somebody knows the way to refresh the ALV OO? . I try to use the method refresh table display ,but the header don't change and the data are the same again.
