Hi Satish,
you need static variables in generic extractors using FM because the function module is not called once but several times from BW (Once for initialization, then depending on size of data packages). Your extraction programm needs to keep some data from the initial call to be able to extract corectly in the next call. If you use standard (DATA) variables, they will be cleared again and again.
Hope that helps
