Ad hoc reports
You can use ad hoc reports to query your database in ways that the standard
lookups don’t support, without having to resort to the full complexity of a third-party
reporting tool such as Crystal.
To create an ad hoc report, you select the business object corresponding to the table the report is based on, the data that you want to use as selection criteria, and the data that you want to include in the report output. In effect, you can use this tool to create customized lookups on the fly.
