START-OF-SELECTION.
OPEN DATASET: OLDFILE FOR INPUT IN TEXT MODE,
SAPFILE FOR OUTPUT IN TEXT MODE,
ERRFILE FOR OUTPUT IN TEXT MODE.
*E Open session:
MOVE: '0' TO BGR00-STYPE,
SESSION TO BGR00-GROUP,
SY-MANDT TO BGR00-MANDT,
SY-UNAME TO BGR00-USNAM,
NODATA TO BGR00-NODATA.
TRANSFER BGR00 TO SAPFILE.
*E Initialize record layout:
DO.
ADD 1 TO N.
ASSIGN COMPONENT N OF STRUCTURE AUXREC TO .
IF SY-SUBRC NE 0. EXIT. ENDIF.
MOVE BGR00-NODATA TO .
ENDDO.
MOVE AUXREC TO BLFA1.
Session data (such as session name, client, user name and the special character for ‘no batch input for
this field’) is passed in table structure BGR00.
The structure BLFA1 is initialized using the ASSIGN statement. Some applications (e.g.MM) also
provide special initialization routines (e.g. INIT_STRUKTUREN_ERZEUGEN in program
RMMMBIMI). For more details, refer to the online documentation for the particular batch input
program.
