Hi sunil,

The below given code shows how a flat file can be uploaded through BDC..

Here is a simple code which is very much clear to understand.

REPORT ztesting.

*Internal tabe to store upload data

TYPES: BEGIN OF table1,

ponumber LIKE ekpo-ebeln,

vendor LIKE ekpo-idnlf,

porg LIKE eine-ekorg,

material LIKE ekpo-matnr,

quantity LIKE ekpo-menge,

price LIKE ekpo-netpr,

expdeldat LIKE sy-datum,

END OF table1.

DATA: it_record TYPE STANDARD TABLE OF table1 INITIAL SIZE 0,

wa_record TYPE table1.

********************Calling a function**********************

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

filename = 'd:\hh.txt' (here the text file is saved in D drive with Tab delimiter which

means giving <tab> between every input field.)

has_field_separator = 'X' "file is TAB delimited

OTHERS = 17.

IF sy-subrc NE 0.

SKIP.

ENDIF.

Hi Sunil,

First i will explain the procedure step by step and will send a sample code plz check it once ok..And also i will attach a flat file at the end of SAMPLE CODE CHECK IT ONCE OK..

Steps:

1.Bulid an internal table first according to ur flat file fields.

2.select the flat file by using PARAMETER.

3.And assign that file path to GUI_UPLOAD function module.

4.Call BDC_OPEN_GROUP is used to open the session.

5.loop that flat file data and palce BDC_INSERT funtion module in that loop for uploading data into database table

6.After loop call BDC_CLOSE_GROUP to close the session.

SAMPLE CODE:

REPORT ybdc_session_mm01 NO STANDARD PAGE HEADING LINE-SIZE 255.

Re: BDC SESSION METHOD EXPLAINED

Former Member — Wed, 09 Jan 2008 08:59:57 GMT

BDC:

Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.

Features :

BDC is an automatic procedure.

This method is used to transfer large amount of data that is available in electronic medium.

BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).

BDC uses normal transaction codes to transfer data.

Types of BDC :

CLASSICAL BATCH INPUT (Session Method)

CALL TRANSACTION

Session method.

1) synchronous processing.

2) can tranfer large amount of data.

3) processing is slower.

4) error log is created

5) data is not updated until session is processed.

Call transaction.

1) asynchronous processing

2) can transfer small amount of data

3) processing is faster.

4) errors need to be handled explicitly

5) data is updated automatically

Reward points if useful.
