Hi

atch Data Communication or BDC is a batch interfacing

technique that SAP developed. It is mainly used for

uploading data into the SAP R/3 system. BDC works by

simulating the user input from transactional screen via an

ABAP program.

The data input data file will come in the form of a flat

file which the user save as file type txt file or prn file

from the Microsoft Excel program. An Abaper will create a

program to read the text file and upload into the SAP system.

Normally, the tcode SHDB will be used to record the

transaction code the user used. After, the simulation, the

Abaper can generate a sample program and modify from there.

It makes the programming easier and faster.

Hi

This is in Breif abt BDC.... I guess this would be helpful...

BDC - BATCH DATA COMMUNICATIONS

BDC allows you to perform database updates in the background using standard SAP transactions. The resultant entries will be as if the user had manually entered the data via SAP. This means that you do not bypass any of the standard SAP consistency checks, authorisations etc. There are two main methods of ABAP BDC, these are Call Transaction and Batch Input. Other methods of update include Direct update, Idoc and BAPI

Data transfer program, an effective and efficient way of transferring large amount of data into your new system (SAP)

Two steps involved in data transfer are "Converting data from your legacy system into the required flat file format" and "Automatically entering data into the SAP system. A SAP data transfer program reads the prepared data from the flat file and moves it into R/3".
