ABAP WRITE statement command with in SAP to display data report to users




The write statement was once the bread and butter of SAP report writing if a user wanted to view the data on screen. This is not used as much for report writing as easier more advanced techniques are available such as the Advance List Viewer (ALV). This does not mean the write statement is no longer used but its use has become more specialised. For example it is still very effective within backgropund batch programs so that output messages appear within the output log report, reports that only need a simple message output and other output uses where a report consisting of columns of data is not appropriate.

Below is an ABAP code extract that demonstrates and explains the basic functionally of the write command.
