how to use SLT for standard BW extractor ?

Hi,

how can we use SLT for the classic BW on HANA standard extractors for eg. 2LIS_13_VAITM where its further loaded to hana optimized IC. ...I mean if we have BW on HANA, and want to use SLT to extract data from ECC to BW on HANA using this standard data extractor.

How can we use webservice to extract data from ECC to BW on HANA using SLT. ? Please advice.

Thanks
