✏️ Explanatory Question
We use the Restore option because when we make changes to the underlying table or temporary table—such as adding a new field—SSRS does not always refresh the dataset automatically. As a result, the newly added fields may not appear in the dataset field list.
Using Restore forces SSRS to re-read the dataset structure and load all the updated fields. This ensures that the report reflects the latest changes made in the data source.
