• Other Need4Viz charts are displayed correctly (vertical table...)
• Other Need4Viz charts are displayed incorrectly (Filter table chart)

Reason and Prerequisites

Environment:

• SAP BusinessObjects Business Intelligence Platform all versions
• Need4Viz : all versions

1.Check the deployment of Need4Viz webapp on your boe Tomcat

Ensure the URL that you fill is working from a user perspective

• Open a web browser (I.E. Chrome) and go to the URL your_boe_server_url/N4VCustomElements/res/images/green_tick.png

2.Edit the config.js file in

~installation_BOE_Folder\nodejs\node_modules\custom_element\ce_libs

Change the following settings

Example for a standard SSL configuration

var URLNodeJSServer = 'https://your_boe_server_url';

var PORTTomcat = 443;

Example for a standard non-SSL configuration

var URLNodeJSServer = 'http://your_boe_server_url'';

var PORTTomcat = 80;
