In our previous releases of OSB, we will search the OSB reports in SBconsole.
But in SOA Suite 184.108.40.206 we will find these reports in EM console.
Login to EM console.
Click on SOA partition and then Click on “Service-bus(Adminserver)”
It will open service bus window . Go to Service bus and click on Message Reports.
It will open the below window where you can search your reports.
