Hi,

For a BDC upload you need to write a program which created BDC sessions.

Steps:

1. Work out the transaction you would use to create the data manually.

2. Use transaction SHDB to record the creation of one material master data.

Click the New recording button or the Menu - Recording - Create

3. Save the recording, and then go back a screen and go to the overview.

4. Select the recording and click on Edit - Create Program. Give the program a Z name, and select transfer from recording.

5. Edit the program. You will see that all the data you entered is hard-coded into the program. You need to make the following changes:

5.1 After the start-of-selection, Call ws_upload to upload the file (the excel file needs to be saved as TAB separated).

5.2 After the open-group, Loop on the uploaded data. For each line, perform validation checks on the data, then modify the perform bdc_field commands to use the file data.

5.3. After perform bdc_transaction, add the endloop.

Execute the program. It will have options to create a batch session or to process directly.

What is the difference between batch input and call transaction in BDC?

<b>Session method.</b>

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.

<b>Call transaction.</b>

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

<b>plz reward points if helpful or if it solves ur query.</b>

Thanks

for bdc first u have to declare an internal table of type bdcdata.

now populate the internal table.

see the structure of the bdcdata.and fill the table.

after populating the internal table

use

call transaction '<transaction name>' using <itab>.

for session method u have to go to shdb transaction and start recording .giving the name of recording.

inthe program call funcion modules

bdc_open_group -

---

>give the session name

bdc_insert -

---

>pass the internal table

bdc_close_group.

sample code for call transaction.

Hi,

Batch data communication (BDC) is used to upload the Master data from legacy system to R3 system.

Pls Go thru the following Link :

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d62292b3-0301-0010-df98-aaac31cd...

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

[Former Member]

hi,

1. Batch Input usually are used to transfer large amount of data. For example you are implementing a new SAP project, and of course you will need some data transfer from legacy system to SAP system.

CALL TRANSACTION is used especially for integration actions between two SAP systems or between different modules. Users sometimes wish to do something like that click a button or an item then SAP would inserts or changes data automatically. Here CALL TRANSACTION should be considered.

2. Transfer data for multiple transactions usually the Batch Input method is used.

Use the CALL TRANSACTION USING statement:

Summary: With CALL TRANSACTION USING, the system processes the data more quickly than with batch input sessions. Unlike batch input sessions, CALL TRANSACTION USING does not automatically support interactive correction or logging functions.

Your program prepares the data and then calls the corresponding transaction that is then processed immediately.

The most important features of CALL TRANSACTION USING are:

Synchronous processing

Transfer of data from an individual transaction each time the statement CALL TRANSACTION USING is called

You can update the database both synchronously and asynchronously

The program specifies the update type

Separate LUW (logical units of work) for the transaction

The system executes a database commit immediately before and after the CALL TRANSACTION USING statement

No batch input processing log

Create a session on the batch input queue:

Summary: Offers management of sessions, support for playing back and correcting sessions that contain errors, and detailed logging.

Your program prepares the data and stores it in a batch input session. A session is a collection of transaction data for one or more transactions. Batch input sessions are maintained by the system in the batch input queue. You can process batch input sessions in the background processing system.

Your program must open a session in the queue before transferring data to it, and must close it again afterwards. All of these operations are performed by making function module calls from the ABAP program.

The most important aspects of the session interface are:

Asynchronous processing

Transfers data for multiple transactions

Synchronous database update

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

A batch input processing log is generated for each session

Sessions cannot be generated in parallel

The batch input program must not open a session until it has closed the preceding session.

http://www.sapbrain.com/TUTORIALS/TECHNICAL/BDC_tutorial.html

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).

Parameter – 5 when you update database table, operation is either successful or unsuccessful or operation is successful with some warning. These messages are stored in internal table, which you specify along with MESSAGE statement. This internal table should be declared like BDCMSGCOLL, a structure available in ABAP/4. It contains the following fields:

1. Tcode: Transaction code

2. Dyname: Batch point module name

3. Dynumb: Batch input Dyn number

4. Msgtyp: Batch input message type (A/E/W/I/S)

5. Msgspra: Batch input Lang, id of message

6. Msgid: Message id

7. MsgvN: Message variables (N = 1 - 4)

For each entry, which is updated in database, table message is available in BDCMSGCOLL. As BDCMSGCOLL is structure, you need to declare a internal table which can contain multiple records (unlike structure).

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.

Error Handling in CALL TRANSACTION

When Session Method updates the records in database table, error records are stored in the log file. In Call transaction there is no such log file available and error record is lost unless handled. Usually you need to give report of all the error records i.e., records which are not inserted or updated in the database table. This can be done by the following method:

Steps for the error handling in CALL TRANSACTION

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

2. BDCTAB like BDCDATA

3. Internal table BDCMSG like BDCMSGCOLL

4. Internal table similar to Ist internal table

(Third and fourth steps are for error handling)

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

6. Loop at itab.

Populate BDCTAB table.

Call transaction <tr.code> using <Bdctab>

Mode <A/N/E>

Update <S/A>

Messages <BDCMSG>.

Perform check.

Refresh BDCTAB.

Endloop.

7 Form check.

IF sy-subrc <> 0. (Call transaction returns the sy-subrc if updating is not successful).

Call function Format_message.

(This function is called to store the message given by system and to display it along with record)

Append itab2.

Display the record and message.

Check this program for session method using multiple transactions.

Have one BDC_OPEN_GROUP, multiple BDC_INSERT s and one BDC_CLOSE_GROUP.

You should have multiple BDC_INSERT s for multiple transactions.

call function BDC_OPENGROUP.

• Build BDC data and cal lBDC_INSERT for transaction 1

• Build BDC data and cal lBDC_INSERT for transaction 2

• Build BDC data and cal lBDC_INSERT for transaction 3

call function BDC_CLOSE_GROUP.

use of methods depending upon amount;

if you have run time validation while updating the data into SAP R/3 Transaction,then use BDC Call Transaction.

example : when you load the data into Sales order then you need to load the into Header text of sales order.

for this ,you have to use Update Mode 'S'.

it is online update and if you small amount of data ,then prefer this one

2. If you have huge amount of data and then prefer Session Method.

we have one more advantage in session method...

suppose file has 1,00,000 records and the if you use all the records at time,then you will get short dump like system time exceed .

then you can split the each 10,000 records into one session and will process.

3. Direct Input method : we prefer this method only few Transaction ,

this will not applicable to when system has customer fields .

if helpful reward points
