Resolution

In some cases, Need4Viz services cannot be declared in the CMC. 

1/ Check if the your SAPBI version is not flagged as a defect version here : 

https://www.need4viz.com/support/kb/faq.php?id=35

2/ If the error encountered is the following one :

Check if your N4V key is activated :

• Open the URL http://xxxx:8209/about to see if the key is activated
• Check the files n4v_xxx_out.log in ~Need4Viz_folder_installation/logs folder, you should have a message concerning the validity of the key

If your key is expired, contact our sales team to get a new one.

Once you have a new key.js file : 

1. Replace the existing one in the ~Need4Viz\nodejs\node_modules\custom_element\ce_libs\ folder
2. Open a PowerShell command window as local administror of the server
3. Change directory to ~Need4Viz_folder_installation/Scripts/
4. Run the Start_Need4Viz.ps1 command

3/ In case of other error :

1. Check the URL used to declare the service is correctly whitelisted (cf. installation guide of N4V)
   
2. Check the port used to declare the service is corresponding to the ports defined in the config.js file (in the ~Need4Viz\nodejs\node_modules\custom_element\ce_libs\ folder)
3. Check the flows (for instance 8201, 8202...) are opened between your tomcat (SAPBI) server in N4V server
