query designer client issue

Hello,

I get an error message when executing a query from the query designer:

"you are only allowed to work in client 200".

However, I do work in client 200.

The system I use has ECC 6 and BI 7 in the same system. Client 100 is ECC and 200 is BI.

How do I solve this? I know I can add a parameter in the URL of the query, but I need to fix this permanently..

When looking in RZ10 in the instance profile, I noticed the following:

"login/system_client 100"

Could this be the problem? Is the instance profile common for all clients in a system?

Any ideas?

Thanks,

F C
