Request Details page in OIM self service appears when you click on a pending approval request in the inbox. Remember that this page goes over the SSL link to OIM.
If you cannot see the details, there might be various reasons for this as listed below:
1. Port 14001 is not open in one of the firewalls.
Make sure you can access OIM self service with FQDN as follows:
https://domain.com:14001/identity or http://domain.com:14000/identity
OR
https://ssodomain.com:443/identity or http://ssodomain.com:80/identity (proxied URIs)
2. The Single Sign On URL or any Front End URL used to access OIM is not configured at the following location:
Enterprise Manager > SOA > soa-infra (soa_server_1) > BPEL process > Approval Task > AdministrationApplication Name : worklist
Host Name: Front End URL that is used to access OIM self service (from step 1)
HTTP port: 80/14000
HTTPs port: 443/14001
URI: /identity/faces/adf.task-flow?_id=ApprovalTask_TaskFlow&_document=WEB-INF/ApprovalTask_TaskFlow.xml
3. OHS server does not have the OIM SSL certificate.
Import the certificate in OHS server.
You have to access OIM self service with URL that includes domain and port as well to see the request details.
