RFC Connection from R/3 to BW fails



I'm getting the following problem. We just upgraded our R.3 system from 4.7 to SAP ECC 6.0. I've just tested the connection from BW to DEV and that's fine. I can connect from BW to DEV and customize extractors etc., no problem.

However, when I try to load data into BW via an infopackage I get no data. The monitor itself doesn't display any messages. It looks like it is still running but in SM37 and AL08 in R/3 there is no RFCUSER active.

Please note that the pre-upgrade DEV was sapdv5 with system number 00

Post-upgrade DEV is sapdv3 with system number 20. In SM59, under the BW connection the settings for Target Host are set to sapdv3 and system number 20. When I test the BW connection I get the following message:

Logon Connection Error

Error Details Error when opening an RFC connection

Error Details ERROR: service 'sapgw20' unknown

Error Details LOCATION: SAP-Gateway on host sapdv5 / sapgw00

I'm not experienced in BASIS but it looks like it's confuding sapdv3 and sapdv5.

Is that correct? How can I solve my problem?
