3)Could we use ME21N transaction, and XK01 transaction, either which one of the transaction, or could we use both the transactions for creating purchase information.

4)How can we use XD02 transaction to change the customer data for updating KNA1 table? Give the steps.

5)How the transaction ME21N is used for to upload the purchase order in BDC?

6)How many transaction we can used in BDC at a time?

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 is Batch Data Communication. It is used for transfering data from non SAP systems to SAP systems.

You can use BDC for any transaction.

There are two types:-

Call transaction and Session method.

While doing BDC, you can do the recording of the transaction which you need(Depending on the data that you need to transfer to SAP) and then execute either of the 2 (Call transaction or session method.)

Steps for MM01:-

1). Go to Transaction SHDB.

There, create a new recording, and give the name of the trasaction and "Start Recording".

2). Enter the data in the fields which are mandatory and also the ones which are necessary for you.

3). Save the recording.

4).Create a BDC program i by selecting your recording, and clicking "Program".

5).Here make an internal table of the fields required for you.

6). Make an excel file of the fields(data) which you want to upload.

7).Execute either seeion or call transaction.

The data is first fetched into the internal table, from the excel file, and then it is updated in the database.

Thanks and regards,
