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

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?
