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.

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 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.

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.

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.

Difference Between Data Type and Data Object

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.

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.

Mixing ESR Data type and XSD Objects

Dear PI forum users,
I have created some XSD containing complex types and thus "acting" as data types.
I would like to use such a complex type defined in XSD in an ESR Data type object.
But when I use the search help in the type column, i can only see other data types objects and not complex types defined in External definition objects.
Do you know if what I want to do is possible and how ?
Thanks a lot.
Jean-Charles

Hi,
i can only see other data types objects and not complex types defined in External definition objects.
This is because only datatypes are shown in the search help. It is not possible to reference an external definition in a data type.
What you can do is:
1.) Recreate the complex types found your external definition as a data type, and reference it in your main data type
or
2.) Encode the data types into your external definition (cleaner)
Hope this helps,

Date Determination using Date Types and Date Rules

Hi Friends,
Iam working on Date Management in CRM 7.0
I have a requirement where I need to calculate the generate the Billing Date present in the Billing Plan tab of the Service Contract.
I have gone through few of the Date Rules defined in the system. My requirement is to subtract the number of days from the Settlement Start Date and populate this Billing Date. It is clear from the existing date rules that we can subtract the days from Settlement Start Date. But I have a new Z field that is created using EEWB, in which user will enter the number of days. Now I need to subtract these days from Settlement Start Date. So, how can I get the reference of this new field. How can I subtract the number of days that the user will enter in this new Z field.
Thanks & regards,
Raju

Hello Robert
I am currently working on service request.I am facing a problem in the date management there.In my service request i have 5 statuses .One of my status is "Pending with consumer".I am using duration settings of service request.By duration settings , i am calculating the duration for which its pending with consumer.I am having 2 response profile one is 24*7 and other is having 9 working hours.In the service request from the SLA configuration i am calculating the escalation date & Time .I need to add the pending with consumer duration with the escalation date and time.I am facing a problem , i am explaining whole problem ..
Let say if the pending with consumer duration is 1440 minutes(that is 24 hours) .I am adding the minutes to the escalation date through the date rule.
I am facing problem that if the service profile is 24*7 then there is no problem but if it is having the 9 hours working service profile then after adding the minutes to it the escalation date is changing to 4 days ahead which is wrong.
I need to add only those minutes for which it is pending with consumer in working hours for the 9 hours service profile
I need to dynamically determine the working hours from the duration then add it to escalation dates when the status is changed from pending with consumer.
Please suggest a badi will work or how to do it.Its urgent as i need to give demo.I will appreciate a quick reply.Please reply

Different date profile and date rule in one transaction type

Hi CRM Experts,
We have requirement that quotation should have validity date based on the contry.We have only one quotation type which will be used in all county.
Now i need to know how can we use different date profile and date rule in one quotation.
Ex -
When the quotation created for russia - expiry date = today + 10 days
when quote created in china = expiry date = today + 25 days
Can it be possible in standared configuration? if not then give me some insight how to achive this?
Regards
Rajesh

Hi, Rajesh.
You can create a Date Rule based on functional module.
Look at example in SAP standard: Date Rule "WTY004 Purchase Date Object":
<?xml version="1.0"?>
<SAPTimeRule>
<ABAPTimeRule function="CRM_WTY_IL_TIMERULE_03"/>
</SAPTimeRule>
Hope this helpful!

Data type of Souce Object Vs BW Object

Hi All,
Our Source system is Oracle system.We have a field 'delivered date' (Database type is 'DATE' and Type in DDIC is 'DATS').
for example: 20.09.2005 08:17:15
Our requirement is to display this data as it is in BW report on ODS.
Shall go for BW infoObject with data type 'CHAR' ? does it lead to any issues while loading from oracle to BW as source data type is 'DATS' and BW Object data type is 'CHAR'?
Is necessary to maiantain same data types here?
If dont go with data type 'CHAR', it is not possible to display date and time together.
I have tested with flat file and it works fine.
Thanks

Hi,
Thanks for your reply.Thats what i had thought of doing.we need not represent it as Date as its combination of date and time.This is the only way to get it i guess.(defining 'CHAR' infoObject and mapping to 'DATS' of source field ).
Any other possibilities?
Thanks

Data Type and Algorithm

I require some help with the line intersection algorithm in PL SQl
I have worked with it on C programs, but not to sure how to create type and variables in PL SQL
I have written the code for the algorithm, i require help to create the data types and testing the algorithm.
I not too sure if my declares variables which will be data type number are correct
( x1, y1, x2, y2, x3, y3, x4, y4,xc, yc;
--a1, a2, b1, b2, c1, c2; /* Coefficients of line eqns. */
-- lr1, r2, r3, r4; /* 'Sign' values */
-- denom, num; /* Intermediate values */
-- Bsign and Asign will have to be type boolean
Create or Replace type Intersect_point object
( x1 number, x2 number, y1 number, y2 number, x3 number, y3 number, x4 number, y4 number, xc number, yc number,
a1 number, a2 number, b1 number, b2 number, c1 number, c2 number, r1 number, r2 number, r3 number, r4 number,
demon number, num number,
Bsign boolean, Asign boolean)
create or replace type body box as
a1:=y2-y1;
b1:=x1-x2;
c1:=x2*y1-x1*y2;
r3:= a1*x3+b1*y3+c1;
r4:= a1*x4+b1*y4+c1;
asign:=r3<0;
bsign:=r4<0;
if ( (r3!=0) and (r4!=0) and (asign = bsign) ) then
return 'False';
-- /* Check signs of r3 and r4. If both point 3 and point 4 lie on
-- * same side of line 1, the line segments do not intersect.
else
a2:= y4-y3;
b2:= x3-x4;
c2:= x4*y3-x3*y4;
r1:=a2*x1+b2*y1+c2;
r2:=a2*x2+b2*y2+c2;
asign:=r1<0;
bsign:=r2<0;
if (r1 != 0) and (r2 != 0) and (asign =bsign) then
return 'False';
/* Check signs of r1 and r2. If both point 1 and point 2 lie
* on same side of second line segment, the line segments do
* not intersect.
else
denom :=a1*b2-a2*b1;
if(denom=0) then
return 'NULL';
--they are collinear
else
num:=b1*c2-b2*c1;
xc:= num/denom;
xc:=a2*c1-a1*c2;
yc:= num/denom;
return 'True';
---- This shows they intersect. HOW can i code to get output for
--intersection points xc yx?
end if;
end if;
end if;

Hi
Can you tell me the your requirement (i.e) incoming receipts and outgoing payments will be cleared (i.e on what basis).

Data Carriers and Data carrier type

Hi Sap Gurus,
Pls let me know is there any necesssity of defining any new Data Carrier types other than PC,
if so at what circumstances and requirements,
also pls throw some light about data Carriers, when is the new data carriers required to be created
at what circumstances and requirements.
is that to access a document from different server or Different system, if it is so why is this required as the documents are always stored in a central content server and Once checked in, any one can access the document from Server,
2) can we make use of Application softwares Installed in one System and make it run in another system, example,
if there are say 4 system totally, among this S1 system1 has Autocad Installed in it ,
rest of the 3 system have not installed Autocad, Can the system 2,3 and 4 edit the auto cad drawings in there system, does at this situations where Datacarries and Data carries types come in to picture,
Please throw some light on this
Thanks and regards
Sathish

Dear Christoph Hopf,
Thanks a lot for your Quick Response
as you have Explained,i assume it is mainly used to store a local copy or extra copy of the Original application files in the system which we use to View them, or if we feel to store the copy in any other system also.
Example Say there are 3 systems S1, S2 and S3
if we are viewing an original file in System S1 and want the same Copy to be stored in System S2 or S3.....
then this data carrier configuration is required if iam right?
But Sir apart from this funtionality can i also know the SAP definition purpose, as it defines data carrier type as below
The system requires the data carrier type in order to exchange data with other data carriers.
This is the case, for example, if the user:
wants to process original application files stored on another computer
wants to use an application installed on another computer
if i can interpret this in right way
it tells us that, by use of data carrier and Data carrier types
we can access a original file stored in Different systems,
if it is so why is this required as the documents are always stored in a central content server and Once checked in, any one can access the document from Server,
2) can we make use of Application softwares Installed in one System and make it run in another system, example,
if there are say 3 system totally, among this S1 system1 has Autocad Installed in it ,
rest of the 2 system have not installed Autocad, Can the system 2, and 3 edit the auto cad drawings in there system, does at this situations where Datacarries and Data carries types come in to picture,
if so how is this made possible?
pls explain with example or Screen shots in Wiki if possible
can u tell me what is the difference between Datacarrier and Datacarrier types with any examples as well
Thanks and regards

XI settings, change of Data Types and XI still maps old structures

Hi,
I have defined XI scenario, where synchronous WebService is being called, and XI calls RFC function module, which returns data. It was working perfectly, until
I have changed the order of few fields in Data Type and added a few new (exactly as the changes in RFC function module).
And now the WebService returns exception, on the first field added to the interface:
<Trace level="1" type="T">com.sap.aii.utilxi.misc.api.BaseRuntimeException: RuntimeException in Message-Mapping transformation: Cannot produce target element /ns1:MT_BMS_Response/CUSTOMERS_PERSON/TITLE. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd at
TITLE is added field.
I have reactivated everything one by one again, clear cache from Integration Builder and Integration Directory, but it does not help and still old structures are being used in XI.
I have tested the Interface Mapping and all fields are transformed correctly.
Please help as it comes a little urgent and I have run out of ideas what to do to refresh the customizing of data types?
Thank you in advance!

Hi Peter,
Yes, I am calling RFC function module from XI.
After I changed the interface of RFC in SAP, I have imported this RFC once more to XI in Integration Builder and new structures appeared.
And exception returned is that first new field added to the RFC and Data Type and so on, returns an exception.
And returned XML structures (in message monitoring) appears to be still old structures.
