I am running on HP-UX, PI 7.1 EHP1 SP03. I am not able to open Alert Configuration/Inbox in RWB. It is related to FQDN issue. Please find below link which is similar to the issue I am facing now. I have maintained FQDN in all the places suggest by SDN like RZ10 icm parameter, Exchange Profile, hosts file. Is there any where i need to maintain FQDN.
One more thing, I am able to open Inbox page if I am executing ALRTINBOX tcode from ABAP. From RWB -> Alert Inbox. I am getting below mentioned (link) error.
