Problem with Transport buffer

Hello,

On our ECC 6.0 system, we have configured Standard 3-system landscape.

The configuration was successful and was distributed and activated successfully.

Now when I am releasing customizing or workbench requests from my development system, they are exported successfully.

But they are not getting updated in the import queue of quality system

While creating the Request, the trget system is also set correctly to the quality system.

Kindly help.
