What is required to refresh data in the Prism data source?

To refresh data in a Prism data source, it is essential to reimport the data in the base dataset or tables and then republish the data source. This process ensures that the most current data is reflected in the analysis provided by the data source.

When refreshing the data, it's crucial to target the underlying datasets or tables, ensuring they are updated with the latest information. After the reimport process, republishing the data source makes the updated data available for use in reports or analyses. This two-step approach of reimporting and republishing is a best practice in maintaining up-to-date analytical insights.

Other choices do not completely fulfill the requirements for a data refresh. Republishing the existing dataset alone does not modify the underlying data, therefore it won't reflect any updates from the source. Deleting and recreating a dataset would be inefficient and unnecessary if the data can simply be reimported. Updating the dataset settings might modify how data is handled but does not inherently refresh the data itself. Therefore, reimporting and republishing is the most effective and standard procedure for ensuring data is fresh and accurate in the Prism environment.
