Table control in internal table

Question

what will b the sequence to creat module pool
i.e  topinclude , pbo ,pai , screen-layout, flow logic ,
i m confused which sequence i follow .

Answer 1

Hi,
In the Object Browser, the module pool code belongs to one of the following categories:
Global fields: data declarations that can be used by all modules in the module pool
PBO modules: modules that are called before displaying the screen
PAI modules: modules that are called in response to the user input
Subroutines: subroutines that can be called from any position within the module pool
By default, the system divides a module pool into one or several include programs. An include program can contain several modules of the same type (only PBO modules or only PAI modules). The main program then consists of a sequence of INCLUDE statements that link the modules to the module pool:
*& Module pool      SAPMTZ10
*& Display data of Table SPFLI
Global data
INCLUDE MTZ10TOP.
PAI modules
INCLUDE MTZ10I01.
PBO modules
INCLUDE MTZ10O01.
In the ABAP/4 editor, you can display the code hidden behind the INCLUDE statements by choosing Edit ---> More functions ---> EXPAND include. With all INCLUDE statements expanded, the module pool looks like this:
*& Module pool      SAPMTZ10
*&           FUNCTION: Display data from Table SPFLI
INCLUDE MTZ10TOP (This is the TOP include:
the TOP module contains global data declarations)
PROGRAM SAPMTZ10.
     TABLES: SPFLI.
     DATA OK_CODE(4).
INCLUDE MTZ10I01 (This is a PAI include.)
*& Module USER_COMMAND_0100 INPUT
Retrieve data from SPFLI or leave transaction
MODULE USER_COMMAND_0100 INPUT.
CASE OK_CODE.
     WHEN 'SHOW'.
          CLEAR OK_CODE.
          SELECT SINGLE * FROM SPFLI WHERE CARRID = SPFLI-CARRID
                                                                  AND       CONNID = SPFLI-CONNID.
     WHEN SPACE.
     WHEN OTHERS.
          CLEAR OK_CODE.
          SET SCREEN 0.
          LEAVE SCREEN.
     ENDCASE.
ENDMODULE.
INCLUDE MTZ10O01 (This is a PBO include.)
*& Module STATUS_0100
Specify GUI status and title for screen 100
MODULE STATUS_0100.
     SET PF-STATUS 'TZ0100'.
     SET TITLEBAR '100'.
ENDMODULE.
You use the ABAP/4 Dictionary to store frequently used data declarations centrally. Objects defined in the Dictionary are known throughout the system. Active Dictionary definitions can be accessed by any application. Data defined in the Dictionary can be included in a screen or used by an ABAP/4 program. You declare global data in the TOP module of the transaction, using the TABLES, STRUCTURE, LIKE statements and others
