BW_METADATA_REPOSITORY IN RSA1 NW 7.3

Hello,

After upgrading BI system to 7.3 I get this error when i try to goto Metadata_Repository in RSA1.

"This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying"

I have already activated the service /default_host/sap/bc/webdynpro/rso_metadata_repository.

I tested the service & the service works fine.

The below services also work fine in smicm.

The system is at level SAPKW73007

Please let us know what can be done further, am i missing any setting ?

Thanks in adavance,

Shradha
