Synchronous

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.

Asynchronous

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.

synchronous -

for example if there is a record which we r updating in a table ..then the related tables all are updated until then the next step is not processed.

whereas in aynchronous a record is updated and simultaneously next step is processed.

Hi,

Synchronous update in which 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.

Asynchronous update, 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).

In call transaction will prefer Synchronous.
