call transaction and session methods

[Former Member]

hi,

can anyone give me standard call transaction program and session method program that are standard but not those that which we write for our purpose to learn in the sense a program which any one could accept as good program.

thanks,

i will surely give ten points to this thread

Hi Sara

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 Sara,

Check the following links:

http://www.sap-img.com/bdc.htm

See below example code :

Call three FM : BDC_OPEN_GROUP,BDC_INSERT and BDC_CLOSE_GROUP.

Once you execute the program and it creates the session at SM35 Transaction.

Hi

What is your exact requirme..

See a program which handles Call Transaction and Session In One Program......

Take a look at the following code :

CALL TRANSACTION 'V-03' USING W_BDCDATA MODE 'N' UPDATE 'S'

MESSAGES INTO W_MESSTAB.

• Si subrc <> 0 : Batch input

IF SY-SUBRC <> 0.

W_COMPT_ERR = W_COMPT_ERR + 1.

IF W_COMPT_ERR EQ 1.

• Open BI

PERFORM TREAT_BDC TABLES WE_BDCDATA

USING P_BATCH ' ' 'O'.

ENDIF.

• Insert BI

PERFORM TREAT_BDC TABLES WE_BDCDATA

USING ' ' 'V-03' 'I'.

ELSE.

REFRESH W_BDCDATA.

ENDIF.

...

• closing of bi session if created

IF W_COMPT_ERR > '0'.

PERFORM TREAT_BDC TABLES WE_BDCDATA

USING ' ' 'V-03' 'C'.

ENDIF.

Hi Sara,

Goto LSMW-> Select Direct Input method in 1st step. These are the standard programs for data transfer.

Otherwise goto SPRO->SAP Reference IMG-> Under this you'll find standard data transfer programs module wise.
