Module Pool Program(SAP-ABAP)

Hi,
I am trying to put CHAIN..ENDCHAIN logic in PAI module
to validate screen.
How sd i use CHAIN..ENDCHAIN ?
Pls guide me with suitable example.
I m waiting for ur reply........
Thanx in Adv.
Prabhas

HI,
See the thread:
Re: Chain - Endchain - Selection-Screen
i copied the below data from SAPHELP for your sake,
To ensure that one or more PAI modules are only called when several screen fields meet a particular condition, you must combine the calls in the flow logic to form a processing chain. You define processing chains as follows:
CHAIN.
ENDCHAIN.
All flow logic statements between CHAIN and ENDCHAIN belong to a processing chain. The fields in the various FIELD statements are combined, and can be used in shared conditions.
CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1> ON CHAIN-INPUT|CHAIN-REQUEST.
FIELD: <g1>, <g 2>,...
MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.
ENDCHAIN.
The additions ON CHAIN-INPUT and ON CHAIN-REQUEST work like the additions ON INPUT and ON REQUEST that you use for individual fields. The exception is that the module is called whenever at least one of the fields listed in a preceding FIELD statement within the chain meets the condition. So <mod1> is called when one of the fields <fi> meets the condition. <mod2> is called when one of the fields <f i> or <g i> meets the condition.
Within a processing chain, you can combine individual FIELD statements with a MODULE statement to set a condition for a single field within the chain:
CHAIN.
FIELD: <f1>, <f 2>,...
FIELD <f> MODULE <mod1> ON INPUT|REQUEST|*-INPUT
|CHAIN-INPUT|CHAIN-REQUEST.
MODULE <mod2> ON CHAIN-INPUT|CHAIN-REQUEST.
ENDCHAIN.
The module <mod1> is called when screen field <f> meets the specified condition for individual fields. <mod2> is called when one of the fields <fi> or <f> meets the condition. If you use the addition ON CHAIN-INPUT or ON CHAIN-REQUEST with FIELD <f>, the condition also applies to the entire chain and module <mod1> and <mod2> are both called.

Creating module pool programming in abap objects

Hello...
I just wanted to know how u create a give modulepool programming in classes and objects.Could anyone tell me the procedure how to do so.And i knew that module pool programming has become obsolete and now everyone are using object oriented concept in module pool programming.soo i want why r they using soo and what is the drawback in using the module pool programming instead of oops concepts.Could anyone give me the clear explanation..

Hello Chadipriya,
You can create module pool program for both ABAP and ABAP OO(Object Oriented).
The thing is in OO u have to declare classes,objects and methods.
Procedure oriented approach
1. Emphasis on tasks
2. Large programs are divided into smaller programs known as functions
3. Most of the functions share global data
4. Data move openly around the system from function to function
Object oriented approach
Emphasis on things that does those tasks
Programs are divided into objects
3. Data structures are designed such that they characterized the objects
4. Functions that operate on the data of an object are tied together in the data structure
5. Data can be hidden and cannot be accessed by external functions
6. New data and functions can be easily added whenever necessary
Go to SE80 ---> Select Program ---> Give ur program name and type this code below :-
REPORT YSUBDEL LINE-SIZE 120.
CLASS parentclass DEFINITION .
PUBLIC SECTION.
DATA : commondata(30) type c value 'Accessible to all'.
METHODS : SHOWVAL.
PROTECTED SECTION.
DATA : protectdata(40) type c value 'Protected data'.
private section.
data : privatedata(30) type c value 'Private data'.
ENDCLASS.
CLASS parentclass IMPLEMENTATION.
METHOD : SHOWVAL.
write:/5 'All data from parentclass shown:-'.
write:/ sy-uline.
WRITE:/5 COMMONDATA,
 /5 PROTECTDATA,
 /5 PRIVATEDATA.
endmethod.
endclass.
CLASS childclass DEFINITION INHERITING FROM parentclass.
PUBLIC SECTION .
METHODS : subval.
ENDCLASS.
CLASS childclass IMPLEMENTATION.
method : subval.
skip 1.
write:/5 'Data of parent shown from child-'.
write:/5 sy-uline.
WRITE:/5 COMMONDATA,
 /5 PROTECTDATA.
Commondata = 'Public data changed in subclass'.
Protectdata = 'Protected data changed in subclass'.
write:/5 sy-uline.
WRITE:/5 COMMONDATA,
 /5 PROTECTDATA.
endmethod.
endclass.
You r using OOPs concepts in module pool program and not module pool programming instead of oops concepts.

Have you got any solution on this.
because i want to use CL_GRID_VIEW_MM->handle_on_data_changed for one of my development related to ME51N.

Module pool programming with Abap Objects

Hi masters,
Somebody tell me that you can directly call a local class in a module pool.
Is that possible?
Can anybody refer me to any kind of information?
Thanks a lot.

Well, thanks for the answer, but not was the one i was waiting for... it wasn't helpful.
But, i've continued searching for answers... and i've found that:
OO Transactions Locate the document in its SAP Library structure
In transaction maintenance (SE93), you can specify a transaction code as an OO transaction.
You either link the transaction code to the Transaction Service of the Structure link ABAP Object Services for persistent objects or to a public method of a global or local class of a program. When calling up a transaction that is linked to an instance method, the system automatically generates an instance of the class in its own internal session.
An example of a link between a transaction code and an instance method of a local class of an unspecified ABAP program:
Example
*& Modulpool DEMO_OO_TRANSACTION *
program DEMO_OO_TRANSACTION.
class DEMO_CLASS definition.
public section.
methods INSTANCE_METHOD.
endclass.
class DEMO_CLASS implementation.
method INSTANCE_METHOD.
message 'Instance method in local class' type 'I'.
endmethod.
endclass.
The DEMO_OO_TRANSACTION program is a module pool of type M that does not contain any screens or dialog modules. Instead, the program contains the definition of a local class DEMO_CLASS.
The DEMO_OO_METHOD transaction code is linked to this program as follows:
The start object of the transaction is Method of a class (OO transaction).
OO transaction model is not selected.
The Class Name is DEMO_CLASS.
The Method is INSTANCE_METHOD.
Local in program is selected and DEMO_OO_TRANSACTION specified.
When the transaction is called up, the program is loaded, an instance of the class is created, and the method is executed.
Leaving content frame
That's what i wanted.
I hope it would be helpful for anyone else.

Debugging a Module Pool Program(Object Oriented ABAP)

Hello Experts,
Could you please advise me on an efficient debugging technoque of Module Pool Program which is based on Object Oriented ABAP?

Hi
Debugging Module pool program using ABAP objects is same as debugging any other report/module pool program.
Click on the Create shortcut icon on the toolbar.
In the popup window choose "System command" and in the command enter "/h"
A shortcut on the desktop would be created
Drag and drop the shortcut to the modal window to set debugging on.
Approach 2:
Create a txt file on the desktop with the following lines:
[FUNCTION]
Command=/H
Title=Debugger
Type=SystemCommandDrag and drop this file to the modal window to set debugging on.
How do I switch between the Classic and New Debugger
From within the ABAP workbench, select the Utilities->Settings Menu
Select the ABAP Editor Tab
Select the Debugging tab within the ABAP Editor Tab
Select the Classic Debugger or New Debugger radio button

How to copy a Module Pool Program from one SAP server to another SAP server

Hi Experts,
My requirement is to copy some Module pool programs from one SAP server to another SAP server which do not have any link.
Please advise on this.
Regards
Dipak

put all relevant objects inside a transport request and release it. this will generate two files, a control file in /usr/sap/trans/cofiles/ and a data file in /usr/sap/trans/data/
you can take these two files, zip'em up and e.g. email them to your destination. There they have to be put into the same directories of that other server and can then be added to the import queue and finally imported.
These last steps would usually be done by an administrator.
Both systems should be on the same release, as far as I know.
Cheers
Thomas

How to Upload a module Pool Program in SAP

Hello All,
I have downloaded My Program Using Report REPTRAN. Now i want to know how we can Upload the Module pool program and Reports in SAP .

Hi Ram,
Use open source project SAPLINK for downloading objects into files and uploading them into SAP. I think REPTRAN is only to download the source code.

How to down load the Module pool program from sap

hi friends,
i am having the Module pool program in one server
it consists of 1 screen.
now i want to down load the Module pool program into another server.
those two server are not linked.
is there any way to copy from one server to another server.
like what we do in smartfroms,that is downloading form and uploading the form.

Hi,
You can down load code from source system and u can upload those in your destination system. You can down load Code as normally like execute SE38 > enter ur program name> click on change button> Utilities(in menu bar)->more utilities>upload/down load>down load in source system & Just use same path with upload instead of down load. So this will help u to transfer code from one system to other.
Screens transfer: SE51> enter ur program name & screen no> click on change button> click on Layout button> Utilities(m)>upload/download>download for down loading a screen from source system.
And follow the same procedure in destination system also just use up load instead of download. to upload a screen in destination system.
Hope useful.
Regards,
BBR.

Can we use Initilization event in module pool program?

Hi All,
Can we use Initialization event in module pool program? If not why?
Thanks In Advance!!!!!!!!!

The runtime environment creates the INITIALIZATION event and calls the corresponding event block (if it has been defined in the ABAP program).
