Crystal Reports for Enterprise 4.0: Change the Data Source for a Report
Crystal Reports enables you to change the data source for an existing report. When you select a new data source, Crystal Reports compares the objects to those in the existing data source, automatically mapping objects whenever the object names and data types match. When objects in the two data sources do not match, you must map objects manually.
In this tutorial, you will change the data source for a report and manually map an object.
