Product:
Cognos Analytics 11.0.12
Planning Analytics 2.0.5
Microsoft Windows 2016 Server

Problem:
When create a new report on a FM package that points to a Planning Analytics data source, you get a error message.

Test of data source works fine.
http://biservername.domain.com:9300/p2pd IBM Planning Analytics / Dynamic Succeeded XQE-DS-0015 TM1 Server Name: planning_sample: “11.3.00003.1”.

Error message:
Firewall Security Rejection. Your request was rejected by the security firewall.
DPR-ERR-2079 – Internal Server Error
URL:/v1/metadata/fmmodels
{
“severity”: “error”, “faultcode”: “Server”, “faultstring”: “The server did something wrong”,
“errorCode”: “CAF_VALIDATION_FAILURE”, “messages”: [ “DPR-ERR-2079 Firewall Security Rejection. Your request was rejected by the security firewall.” ]
}

or

XQE-MD-0007 Unable to establish a metadata connection to data source

Possible solution:
The user in CA11 does not have needed rights inside the TM1 application, login with TM1 Architect and give the user who try to create a report more Admin access inside the TM1 solution. Then test to create a report again.

Can also be that the DOMAIN name is not correct listed inside Cognos Configuration for CAF at Valid domains or hosts field.

– Open Cognos Configuration.
– In the left pane, click on the Cognos Application Firewall node.
– Select the “Valid domains or hosts” property and click the edit button.
– Add additional webserver hostname:port entries as required.

*.domain.com
*.userdomain.com
