hi Vivek ,

A Module Pool program is a Dialog Program (a number of screens that are linked together and use the PBO and PAI events). An Executable programis a Report which generally has a selection screen and a output screen (these types of programs use the Start of Selection, End of Selection, etc events). Also a Executable program can be run via SE38/SE80, but a module pool program must be run from a transaction code as you need to specify the starting screen. So when you are creating the transaction code, you have to first know what type of program you wrote and choose the appropriate type. If you wrote a screen based dialog program, then choose the 'Dialog program' radio button, and if created a report program, then select the second one for an executable report.

Here are links for sample code for understanding module pool programming ,

You can also check the transaction ABAPDOCU which gives you lot of sample programs.

Hope this clears your understanding for module pools !

Reward if helpful !
