Transfer data to a system file

Ever want to save data to a system file from an SAP R/3 ABAP program? Its pretty straightforward. In this case we assume the internal table data_tab contains the information you want to store in the file system. dsn holds the Data set name. The directory must exist in the file structure of your system; record is the record to be written to the file.

data: dsn(20) value '/transfer/matnr',
record(460).
open dataset dsn for output in text mode.

loop at data_tab.
clear record.
move data_tab to record.
transfer record to dsn length 460.
endloop.

close dataset dsn.
