*E SAP structures for BDC:
TABLES: BGR00, BLF00, BLFA1.
*E Old structures:
DATA: BEGIN OF OLDREC,
TELF1(10) TYPE C,
LIFNR(8) TYPE C,
ANRED(2) TYPE C,
NAME1(30) TYPE C,
END OF OLDREC.
*E Help structure for record layout initialization:
DATA: BEGIN OF AUXREC.
INCLUDE STRUCTURE BLFA1.
DATA: END OF AUXREC.
*E Target fields for conversions:
DATA: LIFNR LIKE BLF00-LIFNR,
NAME1 LIKE BLFA1-NAME1,
TELF1 LIKE BLFA1-TELF1.
*E Only for record layout initialization:
DATA: N TYPE I.
FIELD-SYMBOLS .
*E File and session names, nodata flag:
PARAMETERS:
OLDFILE(20) DEFAULT '/tmp/OLD' LOWER CASE,
SAPFILE(20) DEFAULT '/tmp/SAP' LOWER CASE,
ERRFILE(20) DEFAULT '/tmp/ERROR' LOWER CASE,
SESSION(20) DEFAULT 'B420SES041' LOWER CASE,
NODATA DEFAULT '/' LOWER CASE.
The program in the above example transfers telephone numbers from a sequential file. The data records
have the following format: Telephone number (10), vendor number (8), form of address (2), name (30).
The data is checked, converted and formatted so that it can be processed by the standard SAP batch
input program RFBIKR00.
This is a general example. All processing takes places in the same system and in ABAP/4. It would of
course be possible to simplify the data transfer in this particular case.
