Before you start building a report, you need to choose the data which will be printed in the report. You can do this in two ways:
| • | you can choose one of the data sources, which was registered in the report by a programming method. This can be done in the "Data|Choose Report Data..." menu, by marking the needed data source: |
| • | you create a new data source in the "Data|New Data Source..." menu. |
Read more about data sources in the "Data sources" chapter.
Just after you have chosen the data source, it appears in the "Data" window. Now you can use this source in the report. Many reports use only one data source. For reports of "master-detail" type, you need to choose two data sources, related to each other (you can read more about relations in the "Data sources" chapter). Several data sources can also be needed in a report, which prints data from related sources.
