How to change the ROLE: Integration server in business system in SLD

Hi,

I am facing error in communication, becuase the integration server has been attached to in correct business system with incorrect client (001 instead of 700).

In SLD, business system, 'integration' tab there is button "Associate with XI'.

I have selected the role as integration server for the corrrect business system and aslo gave the correct pipeline url for integration server.

When I press the button "Associate with XI" and Save nothing happened.

How do i change my integration server.

Please help.

Regards,

Rehan
