Define a data model in Report Dataset Designer by adding data items. In this window, specify the tables that the report reads. Any table that is listed in this window is read in its entirety when the report runs. Link and filter data items to limit the number of records that the report reads.
A report can read the same table multiple times if the table is listed multiple times in Report Dataset Designer. For example, you can set up a report to read customer records twice: first, the customers who are not blocked, and then the customers who are blocked.
The listed tables become data items in the report. Data items are record variables that enable the report to access table data. The “Report Dataset Designer” figure shows the Customer List report.
