Trying to figure out the variable vaVars.global_notification_context

[Brian DeBlis]

Does anyone know what the variable vaVars.global_notification_context is used for? All the out of the box ITSM conversations start with parsing that variable for a table name and sys_id and it just spins and does nothing when I test it. 

If anyone has insight into what that is and how to set it at the beginning of the conversation, it would be appreciated.

Thanks.

Here is the examples I am talking about:

vaVars.table_name = JSON.parse(vaVars.global_notification_context.toString())['tableName'];

vaVars.sys_id = JSON.parse(vaVars.global_notification_context.toString())['tableSysId'];
