Hi

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

BATCH INPUT METHOD:

This method is also called as ‘CLASSICAL METHOD’.

Features:

Asynchronous processing.

Synchronous Processing in database update.

Transfer data for more than one transaction.

Batch input processing log will be generated.

During processing, no transaction is started until the previous transaction has been written to the database.

CALL TRANSACTION METHOD :

This is another method to transfer data from the legacy system.

Features:

Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.

Updating the database can be either synchronous or asynchronous. The program specifies the update type.

Transfer data for a single transaction.

Transfers data for a sequence of dialog screens.

No batch input processing log is generated.

Hi,

BDC (Batch Data Communication) - is one of the methods for uploading the data. You have two options with BDC, namely Session and Call Transaction.

You would use BDC (Batch Data Communication) mostly to upload transaction data.

First you would record a particular transaction with SHDB simulating sample transaction entry. Then you would use this recording to create a 'Z' program.

With session method a session will be generated that needs to be processed in Transacton SM35 with Foreground, Background, or Errors only mode. You can view and analyze session log after processing the session.

With call transaction you would specify the mode in the program itself. Hence, no session is generated in SM35 in this case.

please visit the following link for more information:

You would use LSMW tool to upload master data.

Visit the following link:

Where you would also find more information about BDC and LSMW.

Hope this will help.
