Can't access Namespaces in Sproxy in ECC

Hi Experts ,

Please help.

I am unable to access Namespace in sproxy.

In my project , ECC QA system was earlier on 320 client and then it got shfted to 330 client.

Now when I go to transaction sproxy and click on source->ESR->it gives error Insufficient authorization.

I got SAP_ALL role to myself ..still problem presist.

ALso I checked SAP_PROXY_ESR RFC dest and its working fine.

Any clue why is it not allowing me
