Difference between Initialization and Load-of-Program

Hi All!

Could anybody tell me what exactly is the difference between Load-of-program and initialization using a sample program?

Thanks in advance...

Jag.

Hi Jag

It seems not so much difference. But INITIALIZATION block is peculiar to executables.

<b>INITIALIZATION</b>: Only occurs in executable programs. The ABAP runtime environment triggers the INITIALIZATION event before the selection screen is processed, at which point the corresponding event block is processed.

<b>LOAD-OF-PROGRAM</b>: When an ABAP program is loaded in an internal session, the runtime environment triggers the LOAD-OF-PROGRAM event, and the corresponding event block is executed.

The Load-of-program event is absolutely necessary for setting the state of an Object Services based transaction. You must initialize the OO Transaction Model at this event. Initialization is too late.
