Report Builder allows you to add live CSV data from the CKAN open-source data portal to the report. This saves you from having to upload the CSV file to your ArcGIS Online account before using it in the report. It also means that any data updates in the CKAN portal will automatically reflect in the associated report, so you don’t have to manually update data in ArcGIS Online.
A list of data portal websites using CKAN can be found at http://ckan.org/instances/#
Before you add a CSV from CKAN portal
1. Make sure that the first field column in the CSV file contains the same values as the report Feature ID field. This will be used as a common identifier to connect the CSV file to the report.
