Disconnecting from the BW server

Hi All,

When I am trying to open any query in the BW development server either in RRMX or query designer it is throwing the error

"Disconnecting from the BW server" and then

Next step

"The BW server we are connected to cannot refresh the query ".

After that we are disconnected from the system and have to logon again.

What can be the issue ?

Would it be a Basis issue or something releated with BW.

Waiting for the solution.

Regards,

Samved
