synchronous means sy-subrc is returned once table and all related tables are updated....

but asynchronous means sy-subrc is returned once concerned table is updated...before related tables are updated.....

Hi,

I synchronus method, becoz in synchronous programs waits to finish the update and in asynchronous program doesn't wait to finish the update.

HI

<b>Synchronous versus Asynchronous</b>

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

DO.

………

PERFORM FILL_BDC_TAB.

CALL TRANSACTION ‘FK02’

USING BDC_TAB

MODE ‘N’

UPDATE ‘S’.

IF SY-SUBRC < > 0.

WRITE: /‘ERROR’.

ENDIF.

ENDDO.

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

DO.

………

PERFORM FILL_BDC_TAB.

CALL TRANSACTION ‘FK02’

USING BDC_TAB

MODE ‘N’

UPDATE ‘A’.

IF SY-SUBRC < > 0.

WRITE: /‘ERROR’.

ENDIF.

ENDDO.

<b>Reward if usefull</b>
