HI,

1) In synchronous update, you do not submit update requests using CALL FUNCTION … IN UPDATE TASK . Instead you use the ABAP statement COMMIT WORK AND WAIT. When the update is finished, control passes back to the program. Synchronous update works in the same way as bundling update requests in a subroutine (PERFORM ON COMMIT). This kind of update is useful when you want to use both asynchronous and synchronous processing without having to program the bundles in two separate ways.

2) COMMIT WORK AND WAIT, This form specifies synchronous processing. The COMMITstatement waits for the end of processing. Control returns to your program after all high priority (V1) function modules have run successfully.

The AND WAIT form is convenient for switching old programs to synchronous processing without having to re-write the code. Functionally, using AND WAIT for update-task updates is just the same as dialog-task updates with PERFORM ON COMMIT

For Synchronous versus Asynchronous:
