This is a sample report program for searching BAPI's. This Report Program will search for all the remote or local BAPI , based on the description text . Say for example, If we require customer related or sales related BAPI'S, then we need to put sales or customer in the description fieldand it will display the list of the related BAPI's. SAMPLE PROGRAM: REPORT ztest_find_bapi. TYPES : BEGIN OF ty_tfdir, funcname TYPE rs38l_fnam, END OF ty_tfdir. TYPES : BEGIN OF ty_tftit, funcname TYPE rs38l_fnam, stext TYPE rs38l_ftxt, END OF ty_tftit. DATA : it_tfdir TYPE STANDARD TABLE OF ty_tfdir, wa_tfdir TYPE ty_tfdir, it_tftit TYPE STANDARD TABLE OF ty_tftit, wa_tftit TYPE ty_tftit. DATA : ws_bapi TYPE char4, chk TYPE char1, field1(30). DATA : ws_lines TYPE i. SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME. PARAMETERS: appl_typ TYPE rs38l_appl, fmode TYPE fmode DEFAULT 'R', desc_txt TYPE char30 OBLIGATORY.

The SSCRFIELDS table is used by the selection screen to store data that can be passed to the program for further processing. Data that can be passed to the program:   FUNCTION CODES : Which can trigger processing in the program.   TEXT : Which will appear on the screen. - The SSCRFIELDS-UCOMM field holds the user defined function code associated with a pushbutton. When the user presses the button present on the selection screen, the program receives a function code which can be used to initialize some kind of processing. - The SSCRFIELDS-FROM _TEXT / TO_TEXT field holds the text associated with the FROM & TO range. - The SSCRFIELDS-FUNCTXT_01 - 05   fields hold the text associated with the pushbuttons on the application toolbar.

INTRODUCTION: - PARAMETERS statement/keyword is used for single field entries in the selection screen. - SELECT-OPTIONS statement/keyword is used for complex selections. - SELECTION-SCREEN statement/keyword is used for formatting the selection screen. - Programmer gets a great deal of control on how to present the User Interface / Selection Screen to the user. Using the options available with the SELECTION-SCREEN statement, the look of the screen can be formatted as per the requirement. - SELECTION-SCREEN is used to form blocks by combining several PARAMETERS , SELECT-OPTIONS , comments etc. on one line. - The standard selection screen of executable programs is predefined and has screen number 1000 . - A SELECTION-SCREEN block can contain keywords like PARAMETERS , SELECT-OPTIONS , COMMENT, PUSH-BUTTON etc. SYNTAX: 1) SELECTION-SCREEN BEGIN OF LINE. ........... ........... SELECTION-SCREEN END OF LINE. This option is used to have several elements in ...

INTRODUCTION: - The PARAMETERS statement creates a single entry field on the selection screen. - The PARAMETERS command is very simple to use and a powerful means to create a user interface. - In layman terms, PARAMETERS statement is used to accept input from user. It is used when we want the user to enter data and depending upon what he/she enters, necessary action is to be taken. - It creates a variable in the program with the same name and the value placed in the field at run time by the user is also placed in the variable. SYNTAX: PARAMETERS <pname> EXTRAS where <pname> is the variable created which holds the the value entered by user at run time. and EXTRAS are the additional properties associated with the PARAMETERS statement, such as: TYPE type [DECIMALS dec ] LIKE fld OBLIGATORY NO-DISPLAY VISIBLE LENGTH vlen AS CHECKBOX [USER-COMMAND fcode ] RADIOBUTTON GROUP group  [USER-COMMAND fcode ] AS LISTBOX VISIBLE LENGTH vle...

INTRODUCTION: - The SELECT-OPTIONS statement creates selection criteria for a particular database field. The existence of the statement in the code causes the selection screen to display at the beginning of the report execution. It creates a line on the selection screen where the user can enter selection criteria for that field. - Basically SELECT-OPTIONS statement determines the user interface for any report program. SYNTAX: SELECT-OPTIONS <sel> FOR <f>                                   [DEFAULT <g> [TO <h>]  [OPTION <op>] SIGN <s>]                                   [MEMORY ID <pid>]                                   [LOWER CASE]        ...

- In SAP, A field symbol can point to any data object. - Field symbols can be created without any attributes or with a type specification . If a field symbol is created without attributes, it takes on the attributes of the field to which it is assigned. If a field symbol is assigned a type specification, the system verifies that the types of the field and field symbol are compatible. - To declare a field symbol in SAP ABAP, use the statement FIELD-SYMBOLS <FS>  [ <type> | STRUCTURE <S>  DEFAULT <WA> ]. Angle brackets (<>) are part of the syntax, which basically allows to distinguish the field symbols from the normal fields in the programs. - The <type>  addition is used to specify the type of a field symbol. If there is no type specification it means the field symbol adopts all of the attributes of the data object. TYPE ANY - Field symbol adopts all of the attributes of the data object. TYPE C, N, P, or X - The ...

In ABAP, we have 8 elementary data types to declare data types: CHARACTER TEXT(C): - Lenght: 1 - 65535. - Default Length: 1. - Initial Value: Blank. - Default Values for the character based data types has to be a text enclosed in single quotes. - Character fields (Type C) are l eft-justified and can be truncated or filled with blanks from the right. - Character fields can also be used as alphanumeric fields. Example: DATA: option TYPE c. DATA: name(30). DATA: subject(20) TYPE c. DATA: title(10) VALUE 'Mr.'. DATA: name(30) TYPE c VALUE 'Sachin Tendulkar '. DATA: name TYPE char30. " This statement will allow name variable to hold upto 30 characters. NUMERIC TEXT (N): - Length: 1 - 65535. - Default Length: 1. - Initial Value: '0....0'. - Numeric text variables hold unsigned positive integers. - This data type should be used for numeric fields t hat will not be calculated like Roll number , Employee number. - We can ...
