ABAP Keyword Documentation → ABAP Glossary
Sequence of data records whose end cannot be predicted. Streams are divided into the stream categories data stream and filter stream. A stream is either a reader stream or a writer stream and therefore always has exactly one stream direction. Furthermore, a distinction is made between the stream types binary stream and character stream. Multiple streams with matching properties can be combined in one stream. In ABAP, streams are implemented using instances of special classes. The transfer of streams is called streaming.
