Sequential Datasets (SAP Library - SAP Query (BC-SRV-QUE))

Sequential Datasets

If you want to generate reports from a sequential dataset without having to worry about data retrieval, create an InfoSet by selecting the Sequential dataset field on the Title and Database screen, enter a file name and a structure created in the ABAP dictionary.

Then, enter the sequential dataset file name you want to read. Its record structure should correspond to the structure specified. You can specify any file name acceptable to the ABAP statement READ DATASET. If you generate a query in this InfoSet and start it online, the file name you specify is displayed as a default value on the selection screen.

Reading from a sequential dataset is performed in binary mode.

You can define field groups on the following screen. Here, you can choose any of the options available when maintaining InfoSets which use logical databases, for example linking additional tables, as well as defining additional fields and structures , parameters and selection criteria, DATA code and START/END code.

When linking additional tables, additional structures and defining additional fields, however, you should be aware of the following special features:

If you define the InfoSet without a logical database, you cannot make any assignments to a database table.

The sequence you specify for sections of code involving additional fields, additional structures and additional tables is important.

When defining an InfoSet without a logical database, it obviously makes no sense to specify code for the GET and GET LATE events of a logical database table. Instead, you specify code for record processing. This option is described in the section Special Features.
