Hi Vijaya lakshmi,

In reports we retreive data from the dictionary and output in the form of list.

where as in module pool we insert,update display the data from the database and as well as we can insert the data into dictionary.

A very Important point to be noted

Validation is done at the database level in reports

but in module pool validation will be done at screen level

and also in executable program,when we execute the program will get into the driver program and execute events wise

where as in module it will execute according to modules

Plz rewards if found helpful,

thanks & Regards,

Ganesh.

hi

1 ) mainly we use reports to display data

we use module pool programs to update database. its sap recommend way to update database

we can do it using reprts also but when updating through reports only that table is updated and not the child tables but in dialog prog along with master table its child tables are also updated

2) dialog progs are more user friendly than reports

3) in reports we cannot have validations while updating . we can do but it needs lot of coding but in module pool validations are done at screen level that is before entering into dbtab so data integrity is maintained

Hi,

Reports:

1. Report means you are displaying the records on the list, by

fetching the records from the table

2. reports are driven by events

3. Reports are Executable Program

Module Pool Programming:

1. module pool programs you are showing the data in a

screen and you can add different functionality like

pushbutton, GUI menu, and PF etc. and it is called as

module b'coz on screen you can't use subroutine ou have to

write the code in module, endmodule

2. where as module pool is driven by transaction codes .

3. In Module pools are execute via T-Codes

Reward If Helpfull,

Naresh.
