Reference data types in interface objects?

How do you create reference data type based on data type in interface object??

First create the reference DT1 in IR then create a new data type DT2 and if you want to create a reference to DT1 then in the editor select Type (3rd coloum) as the DT1 which you can get by double click on Type and then you select "search help" and select DT1 from the list.

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,

HEELLLLP with abstract data types(ie. interfaces)

Hello Java World,
I have a few questions regarding abstract data types(ADT) such as interfaces, etc.
1. Which of the following is allowed in Java ?
interface TA extends student, Employee
class teachAssist implements TA, Cloneable, Sortable{..}
2. ADTs cannot be instantiated only extended/implemented(coded)??
3. Can a interface implements/extend classe(s)?
4. Why is a Vector not an ADT? Is it because it contains implementations for its some of its methods?
Thanks for the help, in advance!!

Hello Java World,
I have a few questions regarding abstract data

1. Which of the following is allowed in Java ?
interface TA extends student, Employee
{...}Allowed (if student and Employee are also Interfaces).
class teachAssist implements TA, Cloneable,
Sortable{..}Allowed.
>
2. ADTs cannot be instantiated only
extended/implemented(coded)??True.
3. Can a interface implements/extend classe(s)?No. An interface simply defines a skeleton...says what methods are present in classes that implement it...therefore an interface cannot 'implement' anything. It may however extend other Interfaces.
4. Why is a Vector not an ADT? Is it because it
contains implementations for its some of its methods?A Vector is not an ADT because it is fully implemented (it contains implementations for ALL of its methods).

My requirment is that for any user,we create 'n' no of Functions/Procs/Packages,etc.Now, all these objects will have data-types defined in them.Can i get an overall count of data-types used in a particular user...(going inside the code and checking the data types it has & the count like
For User : Scott
COUNT(*) DATA_TYPES
10 NUMBER
4521 VARCHAR2

Basic Data Types as Class Objects

Consider the following code using the java.lang.reflect.Method
Class c = Class.forName("java.util.Date");
// get all methods in Date
Method[] c_classes = c.getMethods();
// get the UTC method - UTC(int year, int month, int date, int hrs, int min, int sec)
Method m = c_classes[0];
// get the parameters (all int)
Class[] p = m.getParameterTypes();
This gives a Class array of basic data types (in this case int) - in debug the variable is of type "class" with value "0x16d9220:class(int)"
How do you create a Class object of a basic data type from scratch? I've tried Class.forName("int") and get an exception.
Cheers
Gareth

You could use the class literals.
Class[] primitiveTypes = {
boolean.class,
byte.class,
char.class,
double.class,
float.class,
int.class,
long.class,
short.class,
Cheers, that's exactly what I needed.

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

Setting data type of an object at run time

This is something of an advanced problem, so I hope there's
someone out there who can speak to this. I apologize for the length
of the post, I'm just trying to be clear about a rather unclear
conundrum. --
We all use arrays to hold collections of things. As you know,
an array is its self a type (Array) and so there is no way to
declare, for instance, an array of MovieClips or an array of
Strings. Heres what happens: lets pretend that we have 3 movie
clips clip1_mc, clip2_mc, and clip3_mc, and an Array called
anArray. so we can legally do this. anArray.push( clip1_mc );
anArray.push( clip2_mc ); anArray.push( clip3_mc );. An array of
size 3. Now the code: trace( typeof anArray[0] ); will output
"object." This can be a problem. If you try this: var
newClip:MovieClip = anArray[0]; you get a type mismatch from the
compiler. "Found Object where MovieClip is required." It
necessitates this: var newClip:MovieClip = MovieClip( anArray[0] );
Bummer no?
Ok. So fast forward. Lets assume a class List that uses an
array to hold the items in the list. So the class uses the Array
class in "composition." So you have methods like insert( ); and
retrieve(). Retriece() returns an item from an index in the array.
Because of the aforementioned problem, no matter what type the
thing was going into the list it comes out with type Object because
the retrieve function must return an item of some type, the only
option is to declare the return type of the retrieve() function as
Object. Lets say you know that this is a list of Strings. You could
write the retrieve()'s code like: return String( returnItem ); And
type the object "on the way out" .. but what if you want the list
to work with any type object, you would have to have a variable to
hold the desired type of objects in the list. And then as the
objects are being returned, you'd cast them to the type stored in
that variable. I guess that you'd pass the type to the constructor
of the List: var aList:List = new List( "AddressCard" ); -- That
should declare a List (Array) of AddressCards.
Is there a way to do this? have the type specified in casting
be dynamic?
And the flip-side of that is detecting the name of the class
of an object instance. The thing here would be to try to derive a
String from the name of the constructor function. (which is always
the class name) In actionscript 3 there is a service package--
mx.util -- I think, that has a function to return the qualified
class name of an object. But is there a jimmy rig for this in AS2?
My actual project does not use an Array to implement List. (
or Stack ) It uses a structure called a "linked list" - which is a
whole other topic, but same problem as with Arrays is also present
in the linked list versions and so requires the same solution. If
one is willing to type things explicitly when assigning an item in
the list to a variable of some type, this thing is quite excellent.
But I don't like it. I have the package with docs, code, sample
fla's, diagrams and everything that I would encourage people to
download, look at, try and whatever and then come back here with
any thoughts on it. There is a component with Flash professional
that is a list like structure, but it's so general that it crosses
the line into bloat. Ie: if you are using a list as a stack, you
only need getTop() and pop() and push() not all the other (12 or
so) methods in the class. Mine are patterned after structures from
the C++ standard template library. And the code style is C++, but I
think it's actually easier to read that way.
the files:
http://www.null.bz/ADL_Lib/ADT_Lib.zip
Thanks in advance, for your efforts! I really appreciate all
of it, helpful or not.

First reactions:
>>var newClip:MovieClip = MovieClip( anArray[0] );
Even though you must use a cast to prevent the compile time
error, you don't get an error on this line because the compiler
skips typechecking for values accessed with the [] operator.
>>Is there a way to do this? have the type specified in
casting be dynamic?
Nope. You must effectively type check all objects used
through array elements yourself.

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
Gani

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
reward if useful

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..

Issue with Info Object Transport after changing Data Type

Hi Experts,
We have a DSO which is running past 5 years. And recently(3 days back) we added new fields into that DSO. Delta loaded for last three days and new info object (Say XXX) data populated into DSO.
Now the problem is, We identified that, info object data type is not correct. We used data type NUMC instead of CHAR.So Character information is missing for that field.
Example:
Data from ECC: ABC123
Data Loaded to DSO: 123 (Missed character ABC)
So we deleted data from DSO and changed the info object data type in Development system.
And also I have deleted only last three days delta records from DSO and transported my info object to Production. But its giving error as: Info object contains data in DSO".
But that info object field is empty in DSO. I have already deleted last three days delta.
Do I need to Delete all 5 years data from DSO to change the data type of recently added new info object ?
Please give me your solutions and ideas to solve this issue.
Thank you,
Best Regards,
Santhosh

Hi Raman,
Thank you for your answer.
When I changed the data type of info object in Dev, I deleted the content of DSO. And same thing transported to QA as well. Before importing changed info object, I just deleted the content of DSO from QA. So transport done successfully QA.
But in Production we have a history of past 5 years. So I cant delete all contents of DSO.
So just deleted only the delta request's which contains data for that info object(3 days back, we moved that info object(NUMC data type) to production,So last 3 days delta only loaded for that info object). And tried to transport it. But it was failed. I am sure we need to drop all data from DSO, if I am interested to go with same info object.
I have some comments on your first approach,
1. If we delete info objects from Dev DSO and transport to Production will give transport failure, Why because, my previous transports errors clearly saying that info object contains data in DSO . So it wont allow to remove that info object from DSO.
2.We are using same info object technical name in BO Data federator also. So if we change add new info objects again we need to make changes with BO as well. I am thinking this point as my last option if i cant find any other solution.
Thank you.
Best Regards.

Issue with the Data Type 'Number' in Business Objects

Hi,
I have an Object in the Universe where the Data Type of the Object is a number. This Column pertaining to this Object has certain values in the database out of which there is a 17 Digit Value which is 00000000031101165.
Now, when trying to retreive the same value through Business Objects it is getting rounded off to 00000000031101200 automatically when trying to view in Webi and when trying to retreive the same in Designer/Deski, it displays as 0.000000003110116E+16.
So, I would like to know if there is any other alternative in trying to retreive the Original Value that would not round off. Also, do we have any Limitation for the Data Type Number in Business Objects? The Version we are on is XI3.1.
Note: There are no functions that are used on this Object at the Universe Level and would not like to use any functions here.

What is the underlying database?
It looks like the data is considered to have two decimals, but is rounded to zero decimals.
Only you don't see the number formatting.
Is this a BW query?
Is this a calculated keyfigure?
In the query you can specify the rounding you want and it is also possible to specify it on an infoobject level.
Check those settings...
Hope this helps,
Marianne
PS. Oh, and about the formatting, you can specify a default object format in the universe and override it on the final client (WebI, Crystal)

How to Find the Data Type of the Field In a Database Table

Hi Experts,
I'm currently working on a program which needs to find out the data type of the given field in a database table. In addition to accessing DD03L directly, is there any other workaround such as function module to help me achieve this? It would be helpful if a demo example could be provided.
Thanks a lot.

Hi,
Use this..
DESCRIBE FIELD dobj TYPE typ.
write typ.
type will contain the data type of the object.
