Working with Files on the Application Server Locate the document in its SAP Library structure

 

In ABAP, there is a range of statements for processing data that is stored in sequential files on the application server instead of the database.

 

        OPEN DATASET opens a file for a particular type of access and storage.

        TRANSFER transfers the contents of a data object to a file.

        READ DATASET transfers data from a file to a data object.

        GET DATASET using the addition POSITION the current position of the file pointer in a file is ascertained. Using the addition ATTRIBUTES further characteristics of the file are obtained.

        SET DATASET using the addition POSITION the position of the file pointer is specified. Using the addition ATTRIBUTES further characteristics of the file can be specified.

        TRUNCATE DATASET sets the end of a file to a specified value, thereby changing the size of the file.

        CLOSE DATASET closes a file.

        DELETE DATASET deletes a file.

 

For further details about these statements and their additions, see the keyword documentation.

 

During sequential file operations, the system performs a range of automatic checks, some of which may lead to runtime errors.

Refer also to the chapter:
