BDC Session Does Not get created

Former Member — Mon, 16 Apr 2007 11:17:51 GMT

Hi Guys,

I am trying to execution a transaction using Session method. I am not getting any errors in any of the Function Modules "BDC_OPEN_GROUP", "BDC_INSERT" or "BDC_INSERT". Everything is fine but ultimately when I go to SM35 transaction I don't find the sessions available.

could someone let me know what could be the problem.

Thanks,

ABAP'er.

Hi,

Just check whether you have enabled the<b> keep</b> option in BDC_OPEN_GROUP FM.

If you do no do so, after processing the session, the session name is removed from the log.

Hope this resolves your query.

Reward all the helpful answers.

Regards

Hi,

1. Make sure u finally use

BDC_CLOSE

2. Only after we use the above FM, the session really gets created.

Hi Both,

I have used BDC_CLOSE_GROUP. I don't have problem in that.

I have even used KEEP = 'X'. I don't have problem in that but finally session does not get created.

ABAP'er.

Hi friend,

I think u did mistake when ur providing the perameters.

Plz go through this u can check ur coding.

• Open Batch Input group

CALL FUNCTION 'BDC_OPEN_GROUP'

EXPORTING

CLIENT = SY-MANDT

GROUP = GROUP

USER = USER

KEEP = KEEP.

• Fill in the Data for Transaction in an internal table 'BDCDATA'

FORM INSERT_SCREEN USING PROGRAM DYNPRO.

CLEAR BDCDATA.

BDCDATA-PROGRAM = PROGRAM.

BDCDATA-DYNPRO = DYNPRO.

BDCDATA-DYNBEGIN = 'X'.

APPEND BDCDATA.

ENDFORM.

FORM INSERT_FIELD USING FNAM FVAL.

CLEAR BDCDATA.

BDCDATA-FNAM = FNAM.

BDCDATA-FVAL = FVAL.

APPEND BDCDATA.

ENDFORM.

• Insert Transacton

CALL FUNCTION 'BDC_INSERT'

EXPORTING

TCODE = 'ME21'

TABLES

DYNPROTAB = BDCDATA.

• Close Batch Input group

CALL FUNCTION 'BDC_CLOSE_GROUP'.

Finally to process Batch Input Session, first execute the BDC ABAP. This will create

a BDC session. Run transaction 'SM35' & processes the BDC session.

The difference between CallTransaction and Sessionmethod.

In ‘Call Transaction’, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling. It can also be used for real-time interfaces and custom error handling & logging features. Whereas in

Batch Input Sessions, the ABAP program creates a session with all the transactional data, and this session can be viewed, scheduled and processed (using Transaction SM35) at a later time. The latter technique has a built-in error processing mechanism too.

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

Hi again,

1. Then make sure sy-subrc is zero,

after each FM.

Hi All,

It works find on the Development System and when it is Transported to Acceptance it does not work. Not able to figure out the reason.

I don't get any Error or SY-SUBRC <> 0.

Thanks,

ABAP'er.

Hi Joseph

I faced the same problem. Please follow this link

http://http://scn.sap.com/thread/2078029

In SM35 select the session which is coming as being created and then press shift+f4. If it gets created now then the above mention thread will help.
