Hi,

<b><i>1.For doing any BDC, u have to first do recording.

2.For recording the tcode is SHDB.

3.Click new recording button.

4.For example if u r going to do BDC for item PROPOSAL tocde VA51, then give ur recording name as ZVA51. and tcode as VA51.

5.Give the entries in the tcode.

6.Finally click save button.

7.Then automatically coding will be done by default.

8.Click program and go in to the program.</i></b>

HI,

Just go to Expert Forums » ABAP Development » Data transfers

In search field enter "BDC new " . u can get lot of infomations and materials.

Before post ur question just search in forums.

Thanks.

<b>SESSION METHOD</b>

WE USE 3 FUNCTION MODULES IN THIS SESSION METHOD.

1) BDC_OPEN_GROUP

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.

THIS CREATES A SESSION

2) BDC_INSERT

TCODE: TRANSACTION NAME

DYNPROTAB: BDC DATA

THIS CREATES A SEESION AND DATA IS TRANSFERRED O SESSION.

3) BDC_CLOSE_GROUP – THIS CLOSES THE BDC GROUP.

ONLY ONE SESSION CAN BE CREATED USING BDC_OPEN_GROUP. BUT MULTIPLE TRANSACTIONS CAN BE PROCESSED USING BDC_INSERT.

<b>CALL TRANSACTION</b>

<i>CALL TRANSACTION <TCODE> USING <BDCTAB>

MODE <A/N/E>

UPDATE <S/A>

MESSAGES INTO <MSGTAB>.</i>

A – ALL SCREEN MODE. ALL THE SCREEN OF THE TRANSACTION ARE DISPLAYED.

N – NO SCREEN MODE. NO SCREEN IS DISPLAYED WHEN YOU EXECUTE THE TRANSACTION.

E – ERROR SCREEN. IF THE SCREEN HAS ERROR RECORD, THEN THAT SCREEN WILL BE DISPLAYED.

S - 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 - 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
