Hi

Hope it will help you.

Pls reward if help.

SESSION METHOD

About Session method

In this method you transfer data from internal table to database table through sessions.

In this method, an ABAP/4 program reads the external data that is to be entered in the SAP System and stores the data in session. A session stores the actions that are required to enter your data using normal SAP transaction i.e., Data is transferred to session which in turn transfers data to database table.

Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.

When the program has finished generating the session, you can run the session to execute the SAP transactions in it. You can either explicitly start and monitor a session or have the session run in the background processing system.

Unless session is processed, the data is not transferred to database table.

BDC_OPEN_GROUP

You create the session through program by BDC_OPEN_GROUP function.

Parameters to this function are:

• User Name: User name

• Group: Name of the session

• Lock Date: The date on which you want to process the session.

• Keep: This parameter is passed as ‘X’ when you want to retain session after

processing it or ‘ ‘ to delete it after processing.

BDC_INSERT

This function creates the session & data is transferred to Session.

Parameters to this function are:

• Tcode: Transaction Name

• Dynprotab: BDC Data

BDC_CLOSE_GROUP

This function closes the BDC Group. No Parameters.

Some additional information for session processing

When the session is generated using the KEEP option within the BDC_OPEN_GROUP, the system always keeps the sessions in the queue, whether it has been processed successfully or not.

However, if the session is processed, you have to delete it manually. When session processing is completed successfully while KEEP option was not set, it will be removed automatically from the session queue. Log is not removed for that session.

If the batch-input session is terminated with errors, then it appears in the list of INCORRECT session and it can be processed again. To correct incorrect session, you can analyze the session. The Analysis function allows to determine which screen and value has produced the error. If you find small errors in data, you can correct them interactively, otherwise you need to modify batch input program, which has generated the session or many times even the data file.

CALL TRANSACTION

About CALL TRANSACTION

A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program by

Call transaction <tcode> using <BDCTAB>

Mode <A/N/E>

Update <S/A>

Messages into <MSGTAB>.

Parameter – 1 is transaction code.

Parameter – 2 is name of BDCTAB table.

Parameter – 3 here you are specifying mode in which you execute transaction

A is all screen mode. All the screen of transaction are displayed.

N is no screen mode. No screen is displayed when you execute the transaction.

E is error screen. Only those screens are displayed wherein you have error record.

Parameter – 4 here you are specifying update type by which database table is updated.

S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.

A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).

Steps for CALL TRANSACTION method

1. Internal table for the data (structure similar to your local file)

2. BDCTAB like BDCDATA

3. UPLOAD or WS_UPLOAD function to upload the data from local file to itab. (Considering file is local file)

4. Loop at itab.

Populate BDCTAB table.

Call transaction <tcode> using <BDCTAB>

Mode <A/N/E>

Update <S/A>.

Refresh BDCTAB.

Endloop.

(To populate BDCTAB, You need to transfer each and every field)

The major differences between Session method and Call transaction are as follows:

SESSION METHOD CALL TRANSACTION

1. Data is not updated in database table unless Session is processed. Immediate updation in database table.

2. No sy-subrc is returned. Sy-subrc is returned.

3. Error log is created for error records. Errors need to be handled explicitly

4. Updation in database table is always synchronous Updation in database table can be synchronous Or Asynchronous.

synchronous Update – The program does not wait for the work process to finish the update. Commit Work.

Asynchronous updating. In this mode, the called transaction does not wait for any updates it produces to be completed. It simply passes the updates to the SAP update service. Asynchronous processing therefore usually results in faster execution of your data transfer program.

Asynchronous processing is NOT recommended for processing any larger amount of data. This is because the called transaction receives no completion message from the update module in asynchronous updating. The calling data transfer program, in turn, cannot determine whether a called transaction ended with a successful update of the database or not.

If you use asynchronous updating, then you will need to use the update management facility (Transaction SM12) to check whether updates have been terminated abnormally during session processing. Error analysis and recovery is less convenient than with synchronous updating.

Synchronous Update – The program wait for the work process to finish the update. Commit Work and Wait.

Synchronous updating. In this mode, the called transaction waits for any updates that it produces to be completed. Execution is slower than with asynchronous updating because called transactions wait for updating to be completed. However, the called transaction is able to return any update error message that occurs to your program. It is much easier for you to analyze and recover from errors.

L Local updating. If you update data locally, the update of the database will not be processed in a separate process, but in the process of the calling program. (See the ABAP keyword documentation on SET UPDATE TASK LOCAL for more information.)

Hi Vijay Kumar

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.

http://www.sap-img.com/abap/difference-between-batch-input-and-call-transaction-in-bdc.htm

Among the two methods call transaction is better compared to session bcoz data transfer is faster in it.

Differences between call transaction and session.

Session Method:

1) Data is not updated in the database table until the session is processed.

2) No sy-subrc is returned.

3) Error log is created for error records.

4) Updation is always synchronous.

Call Transaction Method:

1) Immediate updation in the database table.

2) sy-subrc is returned.

3)Error need to be handled explicitly.

4) updation can be synchronous as well as asynchronous.

2) ya u can use using the N mode no screen.

3)u can't handle multiple transaction in call transaction.

4) u can handle multiple transaction in session using the BDC_INSERT fm.

5)When u go to SM35 u can able to see the error records.

Which is best?

That depends on your requirement. Both of them have there advantages.

According to the situation u can choose any one of these.

difference between batch input and call transaction in BDC 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

For session method,these are the function modules to b used.

BDC_OPEN_GROUP

BDC_INSERT

BDC_CLOSE_GROUP

For call transaction,this is the syntax.

CALL TRANSACTION TCODE USING BDCDATA

MODE A or E or N

UPDATE A or S

MESSAGES INTO MESSTAB.

Take a scenario where we need to post documents in FB01 and the input file has say 2000 records (2000 documents, not line items in FB01 but 2000 records)

In the BDC call transaction method

We call the transaction FB01 2000 times (once for each record posting) and if the processing fails in record no 3 it can be captured and start with reocord 4.

Eg: Loop at itab.

call transaction FB01

capture errors

endloop.

In the session method.

We do not explicity call the transaction 2000 times, but all the records are appeneded into a session and this session is stored. The processinf of the session is done wwhenever the user wants it to be done. Hence the errors cannot be captured in the program itself

Check these link:

http://www.sap-img.com/abap/difference-between-batch-input-and-call-transaction-in-bdc.htm

http://www.sap-img.com/abap/question-about-bdc-program.htm

http://www.itcserver.com/blog/2006/06/30/batch-input-vs-call-transaction/

http://www.planetsap.com/bdc_main_page.htm

Batch Input Session method is asynchronous as told by others here. But the advantage of this is that you have all the error messages and the data for each transaction held persistantly. You don't have to code anything for processing them or writing the logs.

But at the same time, the same feature can be disadvantageous if you need to react to an error or if there are too many errors to manually correct in a session. Since the session are created in the program and its execution is done seperately, you loose the trackability of such transactions.

With a call transaction, what was a disadvantage above will become an advantage. Call transaction immediately gives you messages back and you can react to it in your program. But the disadvantage is that, if you have several hundreds of transactions to run, running them from within the program can be resource crunching affair. It will hamper the system performance and you cannot really distribute the load. Of course, you have some mechanisms with which you can overcome this, but you will have to code for it. Also, storing the messages and storing the errored transaction data etc will have to be handled by you in the program. Whereas, in batch input session, your program's job is to just create the session, after that everything is standard SAP system's responsibility.

Ideally, you should do a call transaction if the resources are not a problem and if it fails, put the errored transaction into a session.

You can decide based on the data volume that your BDC is processing. If data volume is high go for session else call transaction will do.The call transaction updates will be instantaneous where as session needs to be processed explictly after creation.

Session Method

1) Session method supports both small amount of data aswell as large amount of data

2) data processing is asynchronus and data updation is synchronus.

3) it process multiple apllication while perfomaning validations.

4) in session method data will be updated in data base only after processing session only.

5) system provide by default logfile for handling error records.

6) it supports both foreground aswell as background process

in bdc we use FM ...

bdc_open_group " for creating Session

bdc_insert " adding transaction and bdcdata table for updating database

bdc_close_group " for closing Session

Call Transaction

1) Call transaction exclusively for small amout of data

2) it supports only one apllication while perfoming validations

3) there is no default logfile, We can explicitly provide logic for creating logfile for handling error records.

we can create logfile by using structure....BDCMSGCOLL

4) it doesn't support background processing.

5) data processing is synchronous and Data updation is Synchronous( default), in

this method also supports daya updation in asynchronus process also.

syntax:

Call transaction <transaction-name> using BDCDATA

mode <A/N/E>

update <L/A/S>

messages into BDCMSGCOLL.

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.
