SAP ABAP Programming Made Easy - Theory & FAQs

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 ...
