    Hi Mridul,

    have you tried this function of different repositories?

    You need to activate the repository service "properties" and not only "discussion" if you want to use this feature, so please go to System Administration -> System Configuration -> Knowledge Management -> Configuration -> CM Reposiotries -> YOUR_REPOSITORY (ie: documents) and check if the repository services "properties" is activated.

    If not, activate it and restart the J2EE Engine.

    If yes, what version are you on?

    Hope this helps,

    Robert

      Hi Mridul,

      you did restart the J2EE Engine after making the configuration changes, right? 😉

      You might check under System Administration -> Monitoring -> Knowledge Management -> Component Monitor -> Services and -> Repository Managers -> YOUR_REPOSITORY to see if everything is green.

      And again you might specify on what patch level you are.

      In any case please consider opening an OSS ticket as software bugs can only be fixed by using that medium and not SDN, and also rewarding points for valuable information.

      Thanks and best regards,

      Robert
