Example:  Business Rule via incident table which is in the 'Global' application scope.

var csCustomTable=new GlideRecord("x_custom_table");

csCustomTable.initialize();

...

...

csCustomTable.insert();

Enable the 'Can Create' option for the 'x_<custom_table>'

1. Navigate to System Definition > Tables

2. Open the record for the custom table. 

3. In the Application Access section, check the box for 'Can create'
