RFC Connection from R/3 to BW fails

203 Views

Hi,

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?

thanks
