No authorization to log on as a trusted system (Trusted RC = 1)

Hi,

I exported all the RFC related tables including trust ones out of our QA system. We then did a system copy from PROD to QA. I then again imported the RFC tables of the old QA and now everything in SM59, SMT1 and SMT2 are as it were before and the RFC destinations work.

But the trust relationships do not work. I get a "No authorization to log on as a trusted system (Trusted RC = 1)". Seems like the security key for the system is invalid.

I DO NOT want to recreate the trust relationships after each system refresh. Any idea how can I get around this issue?

Thanks
