How to change the IFR_ADDRESS (WAS6.20 ABAP Proxy)

Hy,

I tried to implement an ABAP Proxy in a BW3.0B (WAS6.20)and have the following problem.

We have migrated from XI2.0 to 3.0 and the transaction sproxy, still uses the old Address (to the XI2.0 System)

I have already changed the adress in the integration enginge settings and the SLD-Connection of the BW system.

Thank you for your help

Thomas
