Use
You want to be able to generate reports on a sequential dataset, without having to create a program that reads data for the query reports.
Procedure
You can specify any file name providing that it is valid in the READ DATASET ABAP statement.
If you use this InfoSet to generate a query, and start the query online (meaning not in the background) the file name you specify is displayed as a default value on the selection screen.
The system reads in binary mode from a sequential dataset.
You get to the Change InfoSet screen in the field group maintenance.
