I am getting failure to activate the Service Mapping plugin with Demo data

[AnoopRawat]

I tried activating Discovery and ITOM which were successful however Service Mapping with Demo data in my PDI is not getting activated. Got the below message =>

Anoop,

You recently requested the "Service Mapping" plugin to be activated on your personal development instance: dev424447. Unfortunately the plugin was not activated. Please report this issue in the Instance Help section of the ServiceNow Developer Community.

Thanks for being an active member of the ServiceNow Developer Program.

Hi @AnoopRawat 

Please try to install it from developer portal (https://developer.servicenow.com/dev.do#!/manage-instance )

If  from there only you are getting activation failure message , 

Sometimes, the background process times out or the status tracker gets stuck, meaning the plugin is actually active:
• Log into your PDI and type sys_plugin.list in the Application Navigator.
• Search for Discovery (com.snc.discovery) to check its state.
• If it is listed, open the record and click  Repair if available.

• Search for Service Mapping (com.snc.service-mapping) to check its state.
• If it is listed, open the record and click  Repair if available.
