How to extract resule datafrom ECC Z query

Hi,

We all know we can copy the ECC tables and build up the model on HANA for analysis purpose. But if there's already Z query on ECC side to calculate something, is it possible to extract the result data directly from this Z program to HANA instead of rebuilding the whole logics on HANA?

If no, there is any work around to extract the result data directly from ECC Z program to BW side?

Thanks,

Derek
