ABAP workflows in portal

Hi Experts,

We are upgrading portal from 7.0 to 7.4. Currently we have ABAP workflows flowing to portal via uwl from various backend systems.

I have created system object in portal 7.4 for, say, xxx backend and configuration uwl for the same. But the workflows are still going to old portal (7.0).

Any idea what needs to be changed? Is it something like a configuration where we point workflows to flow to new portal instead of old portal? If so, where does it need to be changes? Or is something we have to do in portal config?

Please let me know for more inputs.

Thanks in advance.

Regards,

Manoj
