Difference Between Data Type and Data Object

hi magesh
Data types can be divided into
elementary,
reference, and
complex types.
Elementary Types
Elementary types are the smallest indivisible unit of types. They can be grouped as those with fixed length and those with variable length.
Fixed-Length Elementary Types
There are eight predefined types in ABAP with fixed length:
Four character types:
Character (C),
Numeric character (N),
Date (D),
and Time (T).
One hexadecimal type:
Byte field (X).
Three numeric types:
Integer (I),
Floating-point number (F)
and Packed number (P).
Variable-Length Elementary Types
There are two predefined types in ABAP with variable length:
STRING for character strings
XSTRING for byte strings
Reference Types
Reference types
describe data objects that contain references (pointers) to other objects (data objects and objects in ABAP Objects).
Data Types
1) As well as occurring as attributes of a data object, data types can also be defined independently.
2)You can then use them later on in conjunction with a data object.
3) The definition of a user-defined data type is based on a set of predefined elementary data types.
4) You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary.
5) You can use your own data types to declare data objects or to check the types of parameters in generic operations.
Data Objects
1)Data objects are the physical units with which ABAP statements work at runtime.
2) The contents of a data object occupy memory space in the program.
3) ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type..
4) For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
5) Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type).
6) You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures).
7) As well as fields in the memory area of the program, the program also treats literals like data objects.

Differences between DATA TYPE and DATA OBJECTS

I am new to ABAP,I want to know the differences between DATA TYPE and DATA OBJECTS with some examples.
please help me regarding this.

Hi Ashish,
Data Types:       Are pure descriptions.
               No memory is associated with data types.
               Describes the technical properties of data objects.
EX.
1.     C-CHARACTER
2.     D-DATE
3.     F-FLOAT
4.     I-INTEGER
5.     N-NUMERIC TEXT
6.     T-TIME
7.     P-PACKED NUMBER
8.     X-HEXADECIMAL
9.     STRING-Variable length string.
10.     XSTRING-Variable length byte string.
Data Objects: Are created during runtime.
                They cannot exist without the data Types.
                Occupies memory space.
EX:
1.     INTERNAL DATA OBJECT- Internal Data objects
     LITEERAL- A literal has a fixed value.Ex: WRITE:u201DWORK HARDu201D.
     VARIABLES: Data statement is used to create variables.
EX.DATA: NUM TYPE I.
NUM: VARIABLE defined by data statement.
EX: DATA: PRICE LIKE NUM.
     CONSTANT-It is a data object, which contains a constant value throughout the program.
Can be declared in program by using CONSTANT statement.
EX:CONSTANT: INT TYPE I VALUE 15.
2.     EXTERNAL DATA OBJECT: Are defined in tables i.e In ABAP/4 dictionary you can access this data from table.
         EX: TABLES: SFLIGHT
          DATA: SEATS LIKE SFLIGHT-SEATSMAX.
3.     SYSTEM DEFINED DATA OBJECTS:Space & system variables like SY-UNAME,SY-DATUM, SY-REPID.
4.     SPECIAL DATA OBJECTS:
     PARAMETERS: Are Variables ,which can accept value from user.
      SELECTION SCREEN : Are special internal tables to accept value ranges from user.
3 APPROACHES TO DEFINE DATA OBJECTS.
1.     ELEMENTARY TYPES
DATA: Customer _Name (25) TYPE C,
               Vendor_Name (25) TYPE C.
2.     REFRENCE TO AN EXISTING FIELD:
DATA: Customer _Name2 (25) TYPE C,
              Vendor_Name2 (25) LIKE Customer_Name2
3.     REFRENCE TO NON-ELEMENTARY TYPE:
TYPES: T_NAME (25) TYPE C
DATA: CUSTOMER_NAME TYPE T_NAME
               VENDOR_NAME TYPE T_NAME
4.     RECORD-Information in rows & columns.
DATA: BEGIN OF BOOKING,
                                ID (4) TYPE C,
                                FLIGHT_DATE TYPE D,
                                NAME LIKE CUSTOMER_NAME,
                                END OF BOOKING.
You can also look into SAP help for more information.

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object

Data type and Data object

Hi Friends,
        What is the difference between Data type and Data object?
Best Regards,
VRV Singh

hi
good
Each ABAP program define its own data types using the statement.
TYPES dtype TYPE type ...
and declare its own variables or instance attributes of classes using the statement
DATA var {TYPE type} ...
Within the program or a class, you can also define local data types and variables within procedures. Local variables in procedures obscure identically-named variables in the main program or class.
When creating data types and data objects, there are a number of naming convention that also apply for other local program definitions, such as procedures. These are described in detail in the keyword documentation.
The Additions TYPE and LIKE
The additions TYPE type and LIKE dobj are used in various ABAP statements. The additions can have various meanings, depending on the syntax and context.
·        Definition of local types in a program
·        Declaration of data objects
·        Dynamic creation of data objects
·        Specification of the type of formal parameters in subroutines
·        Specification of the type of formal parameters in methods
·        Specification of the type of field symbols
Constructing New Data Types
The TYPE addition allows you to construct new data types in the TYPES, DATA; CONSTANTS; and STATICSstatements. In the TYPES statement, these are local data types in the program. In the other statements, they are attributes of new data objects, meaning that the newly defined data types are not free-standing. Rather, they are linked to database objects.This means that you can refer to them using the LIKEaddition, but not using TYPE.
To construct new data types, the addition TYPE can be used with the following type constructors:
·        Construction of reference types
REF TO type|dobj
·        Construction of structured data types
BEGIN OF struc_type.
END OF struc_type.
·        Construction of table types
tabkind OF linetype
These data types only exist during the runtime of the ABAP program.
Referring to Known Data Types or Data Objects
Using the additions TYPE or LIKE in the TYPESstatement, local data types in a program can be referred to known data types or data objects. This is mainly the case with user-defined elementary data types. If you declare variables using the additions TYPE type or LIKE dobj with statement DATA, the data type of var is already fully defined before the declaration is made.
The known types or data that are referred to must be visible at the point where the data type or variable is declared.
A known data type can be any of the following:
·        A predefined ABAP type to which you refer using the TYPE addition
·        An existing local data type in the program to which you refer using the TYPE addition
·        The data type of a local data object in the program to which you refer using the LIKE addition
·        A data type in the ABAP Dictionary to which you refer using the TYPE addition. To ensure compatibility with earlier releases, it is still possible to use the LIKE addition to refer to database tables and flat structures in the ABAP Dictionary. However, you should use the TYPE addition in new programs.
The LIKE addition takes its technical attributes from a visible data object. As a rule, you can use LIKE to refer to any object that has been declared using DATA or a similar statement, and is visible in the current context. The data object only has to have been declared. It is irrelevant whether the data object already exists in memory when you make the LIKE reference.
·        In principle, the local data objects in the same program are visible. As with local data types, there is a difference between local data objects in procedures and global data objects. Data objects defined in a procedure obscure other objects with the same name that are declared in the global declarations of the program.
·        You can also refer to the data objects of other visible ABAP programs. These might be, for example, the visible attributes of global classes in class pools. If a global class cl_lobal has a public instance attribute or static attribute attr, you can refer to it as follows in any ABAP program:
DATA dref TYPE REF TO cl_global.
DATA: f1 LIKE cl_global=>attr,
       f2 LIKE dref->attr.
You can access the technical properties of an instance attribute using the class name and a reference variable without first having to create an object. The properties of the attributes of a class are not instance-specific and belong to the static properties of the class.

Data Types
Data types are templates for creating data objects. Data types can be defined independently in the ABAP program or in the ABAP Dictionary. As attributes of a data object, data types can also exist in a non-independent state. Data types do not use any memory space for work data, but may require memory for administration information.
As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary.

Data Objects
A data object is an instance of a data type and occupies as much memory space as its type specifies. An ABAP program only works with data that is available as content of data objects. Data objects are either created implicitly as named data objects, or exanonymous data objects using CREATEDATA.
Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.

Data types and Data object

Can Any one give me Clear definition of Data type and Data objects.
Concept i know clearly.. but unable to explain it..
Regards,
Prasanna

Data consists of strings of bytes in the memory area of the program. A string of related bytes is called a field. Each field has an identity (a name) and a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
 In the ABAP type concept, fields are called data objects. Each data object is an instance of an abstract data type. Data types in ABAP are not just attributes of fields, but can be defined in their own right. There are separate name spaces for data objects and data types. This means that a name can at the same time be the name of a data object as well as the name of a data type.
Data Types:
 As well as occurring as attributes of a data object, data types can also be defined independently. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program (using the TYPES statement) or globally in the ABAP Dictionary.

Difference between relational integrity and data intigrity

hi
could anybody tell me
what is the difference between
relational integrity and data intigrity
tahnx
kals.

hi,
Data Integrity
Data integrity means, in part, that you can correctly and consistently navigate and manipulate the tables in the database. There are two basic rules to ensure data integrity; entity integrity and referential integrity.
The entity integrity rule states that the value of the primary key can never be a null value (a null value is one that has no value and is not the same as a blank). Because a primary key is used to identify a unique row in a relational table, its value must always be specified and should never be unknown. The integrity rule requires that insert, update, and delete operations maintain the uniqueness and existence of all primary keys.
The referential integrity rule states that if a relational table has a foreign key, then every value of the foreign key must either be null or match the values in the relational table in which that foreign key is a primary key.
What is a Relational Integrity?
A relational database contains tables of data which are related to each other. For example, articles are related to the author who wrote them, and conversely, authors are related to the articles they wrote. (Sounds obvious, and it is.) That's the relational part.
When we work with a relational database, we naturally expect that data in related tables stay related. For example, articles written by MartinB should always be related to MartinB and never be confused with articles written by any other author. That's the integrity part.
Relational Integrity is also called Referential Integrity, perhaps because the mechanism for ensuring integrity is implemented by the way the tables reference each other. Both terms are okay with me. I usually just say RI anyway.

Difference between line type and table type

hi,
can any one explain the difference between line type and table type . and how to declare a internal table and work area in BSP's

hi,
Go through this blog, this might help you.
/people/tomas.altman/blog/2004/12/13/sdn-blog-how-to-do-internal-tables-in-bsp
People who have worked with ABAP for a while sometimes forget that the internal table concept is rather different than what exists in most programming languages. It is very powerful, but at the same time can be confusing.
In SAP it is possible to have a table which is the rows and a headerline which is the working area or structure which can then be commited to the table.
With a BSP, if we try to create an internal table within the BSP event or layout we will get the following error: mso-bidi-
 "InternalTableX" is not an internal table - the "OCCURS n" specification is mso-bidi- missing.
class="MsoNormal"><![if !supportEmptyParas]>The problem we are seeing as an inconsistency has to do with the difference between classic ABAP and ABAP Objects. When SAP introduced ABAP Objects they decided to clean up some of the legacy syntax and create stricter rules. However they didn't want to break the millions of line of code that already existed, so they only implemented these stricter checks when OO is being used. Therefore you can declare a table with a header line in a regular ABAP program or Function Module but you can't have one with a header line in OO.
Because everything in BSP generates ABAP OO classes behind the scenes, you get these same stricter syntax checks. My suggestion is that you have a look in the on-line help at the section on ABAP Objects and always follow the newer syntax rules even when writing classic ABAP programs.
In a BSP when we need to work with a table we must always do the following:
1, in the Types definitions create a structure:
 types : begin of ts_reclist,
mso-bidi- style='mso-tab-count:2'> receiver type somlreci1-receiver,
mso-bidi- style='mso-tab-count:2'> style='mso-tab-count: 1'> rec_type type somlreci1-rec_type,
mso-bidi- style='mso-tab-count:2'> end of ts_reclist.
mso-bidi- <![if !supportEmptyParas]> <![endif]>
but we must remember this is only a structure definition and we cannot store anything in it, although we can use it elsewhere as a definition for Structures(WorkAreas)
2, in our Types definitions (this is the best place for this one as we can then access it from many areas without having to create it locally) so in the Types definitions we must create a TableType:
class="MsoNormal"> types : tt_reclist type table of ts_reclist.
class="MsoNormal"><![if !supportEmptyParas]> <![endif]> this TableType is our table definition and again we cannot store anything in it, but we can use it elsewhere as a definition for InternalTables
3, now that you have laid the foundations you can build and in the event handler, it is now simply a case of creating the InternalTable based upon the Table definition:
 data: t_reclist type tt_reclist.
and creating the structure based upon the structure definiton:
<![if !supportEmptyParas]> <![endif]> data: s_reclist type ts_reclist.
as described above, the structure becomes the work area and this is where you assign new values for elements of the table eg:<![endif]>
 s_reclist-receiver = '[email protected]'. "<-- change address
mso-bidi- <![if !supportEmptyParas]> <![endif]>
mso-bidi- s_reclist-rec_type = 'U'.
and then once the data is in the elements of the structure, the structure can be appended to the internal table as follows: class="MsoNormal">
 append s_reclist to t_reclist.
<![if !supportEmptyParas]> <![endif]>
the internal table will then be readable for the ABAP function and can be applied for example as follows: class="style1"> style='mso-tab-count:1; font-family: "Courier New", Courier, mono;'>
class="style1">CALL FUNCTION 'SO_NEW_DOCUMENT_SEND_API1'
 EXPORTING
style='mso-tab-count:2'> document_data = docdata
style='mso-tab-count:2'> DOCUMENT_TYPE = 'RAW'
style='mso-tab-count:2'> PUT_IN_OUTBOX = 'X'
style='mso-tab-count:2'> COMMIT_WORK = 'X' "used from rel.6.10
 TABLES
mso-bidi-font-size: style='mso-tab-count:2'> receivers = t_reclist
class="style1"> <![if !supportEmptyParas]> <![endif]>
<![if !supportEmptyParas]>F inally, a comment from Thomas Jung,
<![if !supportEmptyParas]> when defining my work area for an internal table I like to use the like line of statement. That way if I change the structure of my table type, I know that my work area will still be OK. Second, your types and table types don't have to just be declared in your code. You can create a table type in the data dictionary and use it across multiple programs(also great for method and function parameters). I really push hard for the other developers at my company to use the Data Dictionary Types more and more.
Hope this helps, Do reward.

Difference between line type and internal table?

Hi..
I wanted to know, what is the difference between Line type and Internal Table?

Hi,
Before the 4.7 release in SAP if we want to define an internal table we have to write the defination using the occurs statement and we need to define all the fields using INCLUDE STRUCTURE or indidually all the fields ine by one.
From 4.7 release of R/3 SAP introduced the Line type concept and it's part of the ABAP OOPS concept. for internal table defination we don't need to use the occur statements. Instead INCLUDE structure we need to create a Line type for that structure in Se11 and then we can define the internal table like :
DATA : ITAB TYPE TABLE OF <LINE_TYPE>.
Only thing is this table will be a table without header. So for internal table processing we need to define a work area structure of type line of line type . EX:
DATA: WA_ITAB TYPE LINE OF <LINE_TYPE>.
Hope this helps.
Thanks,
Greetson

Difference between message type and idoc type

Hi
difference between message type and idoc type
Regards
Rama

Hi,
Message Type:
A message type represents the application message exchanged between R/3 systems and R/3 and an external system. A message type characterises the data sent across systems and relates to the structure of the data called an IDOC type.
Diff. with IDOC type
An IDoc type specifies the structure of the data.
A message type specifies the meaning of the data
Diff. b/w IDOC type and IDOC
An IDoc type is the definition of a specific data structure.
An IDoc is an actual instance of data based on an IDoc type. Therefore, there can be many IDocs created from a single IDoc type.
Example:
MATMAS is the message type and MATMAS05 is IDoc type for Material Master.
Thanks,
Shankar

Difference between Material type and Item category

What is the difference between Material type and Item category?
We can differentiate different kind of materails according to material type then why do we have Item category which is also more or less on the same lines.
Both can be considered as a terminology in SAP to group similar kind of materials.
Please let me know the exact difference between the two?

Dear Christino
We can list out so many differences.
When you create a material master record, the material type you choose determines:
- Whether the material is intended for a specific purpose, for example, as a configurable material or process material
- Whether the material number can be assigned internally or externally
- The number range from which the material number is taken
- Which screens appear and in what sequence
- Which departmental data you may enter
- What procurement type the material has; that is, whether it is manufactured in-house or procured externally, or both
Together with the plant, the material type determines the material's inventory management requirement; that is:
- Whether changes in quantity are updated in the material master record
- Whether changes in value are also updated in the stock accounts in financial accounting
In addition, the accounts affected by a material entering or leaving the warehouse depend on the material type.
-Most importantly, Users can be authorized to create materials of specific material types but not based on item category
- Item category will define whether the material should be valuated for stock or it should be considered as non-stock
- Pricing is carried out based on Item Category and not based on Material type

What is the difference between message type and element

hi,
When we create a new variable in BPEL we get the option to create 'simple', 'message type', 'element'
I would like to know what is the difference between message type and element.
thanks
Yatan

A message is part of the service and is usually assigned to one of the operations in the wsdl. For example getPhoneNumer() operation may have an input message of personInput and output of phoneNum. These messages would have a type...maybe of string or decimal or a complex type with multiple values.
An element is typically a complex type that could be defined in an xsd file.
When you create a variable in the bpel, you can declare it as a message or a simple type or an element. As I understand it, the simple types are pre-defined in the schema namespace such as string, decimal, date, etc.
The elements are defined in the xsd files or wsdls and can be a combination of strings, dates, etc or other stuff as well.
The messages are defined in the wsdl as part of the input/output but they are typically assigned a type just like other variables you create.

Difference between IDOC Type and Message Type

Hi, please let me know the difference between IDOC type and Message Type?
Thanks

Hi,
Message type is business name for IDOC you are sending hiding all technical details of the IDOC.
IDOC type gives more technical information about structure of the IDOC.
You will be linking IDOC type to message type while processing IDOC in runtime. You will be specifying message type and IDOC type in WE20 trasaction which says which message will go to which partner whether it is outbound or inbound.

Krishna
