Symptom

• After the installation of N4V on a SAPBI 4.3 deployment, the N4V components are available in the Webi list of charts but inserting a chart on the report doesn't works (blank frame or error displayed)

Reason and Prerequisites

• SAP BusinessObjects Business Intelligence Platform 4.3
• HTTPS Reverse Proxy used to access the BI plateform
• Need4Viz : all versions
  

Steps To Reproduce:

1. Install a full version of Need4Viz on a server
2. configure and start the Need4Viz services
3. SAPBI 4.3 is used and configured behind a Reverse Proxy

Solution

A configuration in the Tomcat needs to be done to declare the reverse proxy settings in the connector.

Open the server.xml file placed in the /tomcat/config directory (on the SAPBI server).

Add the following settings in the Connector tag (where the Tomcat port is defined) :

• proxyName="your_proxy_url"
• proxyPort="your_proxy_port"
• scheme="https"

For instance, if the URL to access the BI Launchpad is https://test-sapbi.xxx.com/BOE/BI

Then the Tomcat connector tag should be configured as :

Once it is done :

• Stop the Tomcat
• Clear the Tomcat cache directory (delete the tomcat\work\Catalina\localhost\BOE folder)
• Start the Tomcat
• Clean your BILaunchpad session
• Test a Webi report with a N4V component
