hi all.

i done a recording in shdb on transaction mm02.. the code of bdc recording is as follows

report YASEC_BDC

no standard page heading line-size 255.

include bdcrecx1.

parameters: dataset(132) lower case.

DO NOT CHANGE - the generated data section - DO NOT CHANGE ***

*

If it is nessesary to change the data section use the rules:
1.) Each definition of a field exists of two lines
2.) The first line shows exactly the comment
'* data element: ' followed with the data element
which describes the field.
If you don't have a data element use the
comment without a data element name
3.) The second line shows the fieldname of the
structure, the fieldname must consist of
a fieldname and optional the character '_' and
three numbers and the field length in brackets
4.) Each field must be type C.

Definition- Declaring BDC Table

DATA: BDC_TAB LIKE STANDARD TABLE OF

BDCDATA INITIAL SIZE 6

WITH HEADER LINE .

The internal table used to collect the transaction’s information must be declared “LIKE BDCDATA”.

Filling BDC Table – Method #1

FORM FILL_BDC_TAB.

REFRESH BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-PROGRAM = ‘SAPMF02K’.

BDC_TAB-DYNPRO = ‘01016’.

BDC_TAB-DYNBEGIN = ‘X’.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = ‘RF02K-LIFNR’.

BDC_TAB-FVAL = ‘TEST1’.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = ‘RF02K-D0010’.

BDC_TAB-FVAL = ‘X’.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-PROGRAM = ‘SAPMF02K’.

BDC_TAB-DYNPRO = ‘0110’.

BDC_TAB-DYNBEGIN = ‘X’.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = ‘LFA1-STRAS’.

BDC_TAB-FVAL = ‘123 Main St.’.

APPEND BDC_TAB.

CLEAR BDC_TAB.

BDC_TAB-FNAM = ‘BDC_OKCODE’.

BDC_TAB-FVAL = ‘/11’.

APPEND BDC_TAB.

ENDFORM.

Filling BDC Table – Method #2

FORM FILL_BDC_TAB.

REFRESH BDC_TAB.

PERFORM POPULATE_BDC_TAB

USING:

‘1’ ‘SAPMF02K’ ‘0106’,

‘ ‘ ‘RF02K-LIFNR’ ‘TEST1’,

‘ ‘ ‘RF02K-D0010’ ‘X’,

‘1’ ‘SAPMF02K’ ‘0110’,

‘ ‘ ‘LFA1-STRAS’, ‘123 Main St.’,

‘ ‘ ‘BDC_OKCODE’, ‘/11’.

ENDFORM.

FORM POPULATE_BDC_TAB USING FLAG VAR1 VAR2.

CLEAR BDC_TAB.

IF FLAG = ‘1’.

BDC_TAB-PROGRAM = VAR1.

BDC_TAB-DYNPRO = VAR2..

BDC_TAB-DYNBEGIN = ‘X’.

ELSE.

BDC_TAB-FNAM = VAR1.

BDC_TAB-FVAL = VAR2.

ENDIF.

APPEND BDC_TAB.

ENDFORM.

This two subroutine method to fill the BDC table is preferable because the “POPULATE_BDC_TABLE” subroutine is reusable throughout all batch input programs.

Example #1 - Change Vendor (Call Transaction Method)

Example #1- Declaration Section

CALL TRANSACTION ‘FK02’

USING BDC_TAB

MODE ‘N’

UPDATE ‘S’.

IF SY-SUBRC < > 0.

WRITE: /‘ERROR’.

ENDIF.

ENDDO.

With synchronous updating, we can check SY-SUBRC to determine the success of the transaction and the actual update to the database.

asynchronous updating

DO.

………

PERFORM FILL_BDC_TAB.

CALL TRANSACTION ‘FK02’

USING BDC_TAB

MODE ‘N’

UPDATE ‘A’.

IF SY-SUBRC < > 0.

WRITE: /‘ERROR’.

ENDIF.

ENDDO.

With asynchronous updating, we can check SY-SUBRC to determine the success of the transaction only, not the actual update to the database.

Error Handling

Write an error report.

Send the record(s) in error to an error file.

Create a batch input session with the record(s) in error.

To store error messages ( CALL TRANSACTION )

data: begin of Tab_Mess occurs 0.

include structure bdcmsgcoll.

data : end of Tab_Mess,

CALL TRANSACTION ‘FK02’ USING BDC_TAB MODE ‘N’ UPDATE ‘S’

MESSAGES INTO TAB_MESS.

IF SY-SUBRC NE 0.

WRITE: / Tab_MESS-TCODE, Tab_MESS-DYNUMB, Tab_MESS-MSGTYP ,

Tab_MESS-MSGID.

ENDIF.

i am giving you example for Change Vendor you practice for ur tcode

For our example, we will use the “Change Vendor” transaction (“FK02”) to add a street address to an already existing vendor.

Step #1

Use “SystemStatus” menu path to determine online program name (SAPMF02K), screen number (0110)

Step #2

Use “F1” key and “Technical Info” pushbutton in each screen field to be filled to determine the field name.

Step #3

Determine how to proceed in the transaction

(save the record by clicking on the ‘Save’ pushbutton or pressing the ‘F11’ key).

BDC Table Contents

After researching the transaction we can determine the contents of the BDC table.

PROGRAM DYNPRO DYNBEGIN FNAM FVAL

SAMPF02K 0106 X

RF02K-LIFNR TEST1

RF02K-D0110 X

SAMPF02K 0110 X

Batch Input Methods

“CALL TRANSACTION USING”

STATEMENT

Call transaction - for data transfer

Processing batch input data with CALL TRANSACTION USING is the faster of the two recommended data transfer methods. In this method, legacy data is processed inline in your data transfer program.

Syntax:

CALL TRANSACTION <tcode>

USING <bdc_tab>

MODE <mode>

UPDATE <update>

A Display all

E Display errors only

N No display

S Synchronous

A Asynchronous

L Local update

The process flow of CALL TRANSACTION

A program that uses CALL TRANSACTION USING to process legacy data should execute thefollowing steps:

Prepare a BDCDATA structure for the transaction that you wish to run.

Prepare a internal table to store error messages Tab_Mess like structure of BDCMSGCOLL.

With a CALL TRANSACTION USING statement, call the transaction and prepare the BDCDATA structure. For example:

CALL TRANSACTION ‘MM01' USING BDCDATA MODE 'A' UPDATE 'S'. MESSAGES INTO TAB_MESS.

IF SY-SUBRC <> 0.

<Error_handling>.

ENDIF.

Overview of Batch Input Session

The first batch input method is to create a batch input session. It is the processing of this batch input session that updates the database, not the execution of the batch input program.
