Using a Report Writer report as a data source for Crystal reports
You can use the data and metadata from a Report Writer report to create a Crystal report. By using the Report Writer report as a data source in Crystal, you can take advantage of the business logic in Report Writer. You do not need to understand table relationships to define the report in Crystal.
Before you begin, use a copy of an existing report or create a new report to use as the data source. The report must be a single-format report. If the report you are working from is a multi-format report, then you need to convert it.
