Data Extraction from BW to ECC resulting high load on ECC.

Hello,

We have seen a lot of load on the ECC because of data extractions of the BW. This had a performance impact on the ECC.
Apparently BW only connects to the CI of ECC. Is there any configuration somewhere on the BW system due to which it connects to CI and not AS?

Can we route the data extractions to AS? Is this possible anyhow?

Thanks.
