hi

synchronous process is processed one by one record

if error is occured it won't process that record that will send to log

in asynchronous process if the error occured it skips that record

and process it another one

but in the processing wise same performence timing when comparing the synchronous and asynchronous( when log is created)

Hi

<b>reward if usefull</b>

<b>Synchronous <u>versus</u> Asynchronous</b>

<b>Synchronous</b>

DO.

………

PERFORM FILL_BDC_TAB.

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.

<b>asynchronous</b>

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.

Hi,

Sychronuos --- processes in sychronous to database update, means wait till data base update to complete before proceeding to next

Asynchronous -

---

data base update is not in line with your transaction means, before database to get updated processing of next record will start
