MODULE POOL VS. EXECUTABLE PROGRAM

[Former Member]

Both programs can use to call screens (created in screen painter).

What are the differences between them?

module pule programe is need the ztransaction name(se93), we can also execute MP s with out using se93 with call sceen<screen no)ok

starting of the code just put call screen <screen no>, then u can directly execute prog..

ok

Can you give an example on this statement?

Thanks.

Executable programs are Report programs which are driven by Events.

Module pool programs are driven by transaction code

hi,

like this...

u can call screen from normal report

matnr TYPE marc-matnr,

werks TYPE marc-werks,

<i>The major difference between the program flow of an executable program and a dialog program is that in a dialog program, you can program screens to appear in any sequence you want.

In executable programs, the screen sequence is controlled by events, which occur in a fixed order.

In a dialog program, the programmer is free to program any sequence of screens, and the user can affect the program flow by his or her actions.

However, it is still possible to call a freely-defined screen sequence within an executable program and thus to branch into a form of dialog program.</i>
