Hi,
I am going to work on data migration using LSMW.
Now the first step in data migration is exporting data from legacy system i.e unloading leagcy system data.
If the legacy system does not provide any functionality for this purpose suitable proghrams are supposed to be written for data extarction.
Being an ABAPer is it my responsibility to write the program for data extarction from legacy system or someone else's ?
