How to use BDC in programs.

Do not be afraid to use bdc. It is just as easy as ABC.

Pre. Req: - Know how, Get the user, functional or test on the transaction that you want to create.

Step 1
1. Transaction code : SHDB (Transaction Recorder: Recording Overview)
 - Click on "New Recording". Example below.
2. Start the recording. And after doin the FB01 transaction within this sample it will show the screen below. 

Press the button save.

3.Then go back to the main screen. shdb. Find the recorded coding and click. Function module.
- create the function group if it havent exist. in this example i will be using a local copy just to copy out the codes.


4. Go to se37. copy the codings out.

------------
From the line starting


perform open_group
.
.
.
.
perform bdc_transaction

Please do remember to copy the sub routine ( double click into it ) 

* notes to remeber. in the 
it will consist of putting the bdc in batch or direct processing

  IF P_CTU <> 'X'. "batch processing
    CALL FUNCTION 'BDC_INSERT'
         EXPORTING  TCODE     P_TCODE
         TABLES     DYNPROTAB BDCDATA
         EXCEPTIONS OTHERS    1.

  ELSE.         "direct processing 
    CALL TRANSACTION P_TCODE USING BDCDATA
                     MODE   P_MODE
                     UPDATE P_UPDATE
                     MESSAGES INTO P_MESSTAB.

  ENDIF.

TIPS: - If you are having problem saving debug using MODE 'L'. It will show you where is going wrong during BDC.
     CALL TRANSACTION CN_FB01 USING TA_bdcdata  MODE 'N' UPDATE 'S'  MESSAGES INTO lt_messtab.
