Predefined object type for Purchase order release stratergy

dear experts,
There are already predefined object type for purchase order like bus2012 where i can create new events and methods. I want to know is there any predefined objects for purchase order release strategy. The requirement is there i want to define method, that should display the po release screen. If i bind this method with work flow template, mail should be triggered and if i click the mail po release screen should be opened for respective material...
regards,
Kandhan G

Hello
I'm using the BUS2012 Object type in workflow task but in simulation the task run correct but in the transaction when modify a purchase orden the task send an error...
maybe the error is similar...did you solve this problem?..
Thanks!

Annotation Type XmlType , WebServices

hello
i've an sql/plsql web service that return complex data type as xml
in order to access the webservice in my application i generate webservice cproxy clinet java class
untill no all thing is ok
now i go the proxyclinet.java class to execute the web service method the result is returned as string which is need to be parsed as xml nodes which is ok
now suppose that i want to do another solution that is based on the Annotation Type XmlType to define a class to store the return data type as java object fro the xml data
the
java code as follow
package TestWebService;
import java.lang.annotation.ElementType;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorOrder;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlType;
<xs:complexType name="Employee">
   <xs:sequence>
       <xs:element name="EMPNO" type="xs:int" minOccurs="0"/>
        <xs:element name="ENAME" type="xs:string" minOccurs="0"/>
        <xs:element name="JOB" type="xs:string" minOccurs="0"/>
        <xs.element name="SAL" typr="xs:anytype" minOccurs="0"/>
   </xs:sequence>
</xs:complexType>
@XmlType(propOrder = { "Number", "ENAME" ,"JOB","SAL"})
public class WebServiceDataType {
    public WebServiceDataType() {
        super();
    private int empno;
    private String ename;
    private String Job;
    private double sal;
    public int getEmpno() {
        return empno;
    public void setEmpno(int Number) {
        this.empno = Number;
    public String getEname() {
        return ename;
    public void setEname(String ENAME) {
        this.ename = ENAME;
    public String getJob() {
        return Job;
    public void setJob(String JOB) {
        this.Job = JOB;
    public double getSal() {
        return sal;
    public void setSal(double SAL) {
        this.sal = SAL;
}How i can make the return service data type to be converted to this class data type rather than string !!!

PDF Custom Annotations Types?

Can some kind reader comment and/or point to documentation on PDF's Custom Annotation Types?
I was first introduced to those by Aandi Inston's reply to my "Click to Dial Plugin" posting.
Unfortunately, such posting seems to have been pulled (lost?, relocated?, bitbucketed?) from the forum.
My objective is to programmatically insert several links of different types in my PDF files. I intend to have a type for voice phone numbers, another for fax numbers, and yet another company or client ID, etc.
The part below refers to a plugin (to be written).
Later on, when the user clicks on a phone number, a call will be placed, clicks on a fax number will result in the document being faxed, while a click on an ID will result on a database lookup.
I don't want to go through the hassle of studying the page's geometry to determine whether a phone number is voice or fax. I am just looking for a way to mark the different links, giving each one of them a type, which will be passed to the plugin upon a link being clicked.
I recall that Aandi's explanation made an exact match for my application, but as I said before, his posting is gone.
-Ramon

Perhaps the use Custom Annotation Types (CAT) is an overkill? It seems that when a CAT is defined, an annotation handler has to be registered, and such handler provides the drawing. In my case I don't need any custom drawing. I just need to mark somehow the different links, assigning a type to each.
Thanks for sharing your expertise, and helping the PDF format to become more useful and widespread...

The argument does not represent an annotation type

Hello, i stated getting this exception today:
java.lang.IllegalArgumentException: The argument does not represent an annotation type: <MyAnnotationType>
even if <MyAnnotationType> is an annotation and the processor used to work unmodified.
Is there a way to check if the TypeElement before calling roundEnv.getElementsAnnotatedWith(annotation) ?
The code in question is:
     @Override
     public boolean process(Set<? extends TypeElement> annotations,
               RoundEnvironment roundEnv) {
          for (TypeElement annotation : annotations) {
               for (Element el : roundEnv.getElementsAnnotatedWith(annotation)) {
          return true;

Annotation Type Declaration

Why in anno type declaration some types look like methods ?
Example:
public @interface MyAnnotation {
   String doSomething();                   //HERE
   int count; String date();                 // int is fine but , String , why its a method ?
Usage:
@MyAnnotation (doSomething="What to do", count=1,
               date="09-09-2005")
public void mymethod() {
}

ya ..
it says
"The annotation type definition looks somewhat like an interface definition where the keyword interface is preceded by the @ character (@ = "AT" as in Annotation Type). Annotation types are, in fact, a form of interface, which will be covered in a later lesson. For the moment, you do not need to understand interfaces.
+The body of the annotation definition above contains annotation type element declarations, which look a lot like methods. Note that they may define optional default values.+ "
But does not explain why they are metods , observe in the above example that ,
primitive int is directly declared , not as a method ,
Then all should be methods ..

Advanced Predefined Annotations used with EJB3.0

Hi
I want to tune my Application which is consisting of EJB3.
I am using ejb3 Annotations on to my source files .
I didn't found anything annotation related to pooling , except with jboss specific .
Say for example i want to set max beans in pool as 50.
Please tell me how can i do this ??

Wrong. While it is good to design and plan EJB applications, the one thing you shouldn't do is get in the way of the server. If the server decides it needs to pool or tune a pool it is using, let the server handle it. It can do it far better than you can as it has all the information, you don't (with good reason). The only thing you should be worrying about is the environment of the server, such as how many database connections to pool.

Map xsd complex type to existing java class without adding JAXB annotations

Hello
I've got a case where I should map an xsd complex type to an existing Java class without modifying that class, i.e. without adding JAXB annotations to that class.
Is this possible somehow?
As far as I've understood, the <javaType> declaration (adapter, parse/print methods) can only be used for xsd simple types.
Thanks, Tom

It should be possible to implement an XmlAdapter<...,...> which performs the required conversion between the original type and a JAXB-annotated type. Then, at the places where the original type is used, the @XmlJavaTypeAdapter annotation would be used.
The xjc compiler supports this for xsd simple types (xjc:javaType annotation), but not for complex types.
Any idea why this is restricted to simple types?
Would it be possible to implement a xjc plugin which does this for complex types?
Thanks Tom.

Diff b/w reference type and elementary type

hi all
can any one what is the diff b/w reference type and elementary type in data element ....
thanks
lokesh

The data type attributes of a data element can be defined by:
Specifying a domain whose attributes are copied by the data element.
Specifying a build-in type where the data type, number of places, and possibly decimal places can be directly specified.
Specifying a reference type, i.e. reference to a class, an interface, a type defined in the Dictionary, a built-in type, or a generic reference to ANY or DATA.
In the maintenance screen you can set the option you require by setting the appropriate flag (domain, built-in type, reference type) and filling in the corresponding input fields.
A reference type is a reference to another type. There are the following kinds of reference types:
Reference to a class or an interface
Reference to a type defined in the Dictionary
Generic reference to ANY, OBJECT, or DATA
Reference to a built-in Dictionary type with specification of the length and possibly also the decimal places
You can use a reference type to define the data type properties for a data element, or for typing the component of a structure or the line type of a table type.
In the field Referenced type, enter the name of a class, an interface, the generic references DATA, OBJECT, ANY, or the name of a type defined in the Dictionary. If the reference type is to be a predefined Dictionary type, choose the reference to the predefined type. Enter the number of characters and, if required, the number of decimal places.
where as
The data class describes the data format at the user interface.
If a table field or structure field or a data element is used in an ABAP program, the data class is converted to a format used by the ABAP processor. When a table is created in the database, the data class of a table field is converted to a corresponding data format of the database system used.
You can find a detailed description of the data classes allowed in the ABAP Dictionary in Overview of the Data Classes.

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
thanks and regards

Value in data type p field not displayed properly when download to UNIX

Hi,
One of my programs downloads a file to UNIX server,
here the data which i am downloading, one of the fields is of type P (it is of domain type DEC).
The field displays very strangecharactershen i view it in UNIX server.
I am using OPEN DATASET in binary mode statement.
my system is unicode enabled ECC6.0 version
Please help

That is normal, type "P" packed fields with two decimal digits packed into each byte Use another type of field, if you want the field to be readable..
Look at [Predefined ABAP Types|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fc/eb2fd9358411d1829f0000e829fbfe/frameset.htm]

Forms wizard does not allow what type of field to use as default?

I have Acrobat 9 and am creating a form that has ober 300 fields (for logging calls).
The issue I have is when starting the wizard, it defaults to creating all 300 fields as TEXT boxes. I'd like to have them as COMBO BOXES. I see no way to change them or to change how adobe 9 creates them at start up of the wizard.
I know I can do them one at a time and even copy and paste groups of them, but they don't line up as well when I do it this way.
Any ideas?
Thanks

Hi!
Thanks very much for your reply. Precisely what I'm hoping to do is stamp annotations--to the point that I've prototyped three whole toolbars of fixtures, sensors, and wall controls with mocked up rubber stamps, and marked up several whole buildings worth of construction plans to show the concept.
Okay--so the stamp annotation looks terrific. How do I find out more? The Acrobat 9.1 SDK (under "Plug-ins and Applications", then "Creating Annotations") says this:
Several annotation types exist, which are identified by their subtype. Each subtype can have additional properties that extend the basic ones. The subtype for text annotations (also called notes) is text. The subtype for link annotations is link. The Acrobat core API contains two built-in annotation typedefs PDTextAnnot and PDLinkAnnot. A PDTextAnnot object corresponds to a text annotation and a PDLinkAnnot object corresponds to a link annotation.
That paragraph (and the subsequent pages in that chapter) led me to think that my options were:
Text annotation
Link annotation
3D annotation
Dive into the Cos layer and create a custom annotation
Where can I find documentation on the Stamp annotation? (I do have the Stamper sample application.)
Thanks again,
John Murdoch

Binary Data type in Logical - Is it a bug?

Binary Data type in Logical - Is it a bug?
Hi ,
I am using SQL DM 3.0.0.665. I need your thoughs on following.
I have an attribute in logical model with binary datatype. As I generate physical, SQL DM putting the column in BLOB data type. I thought binary means 1 bit ON/OFF type.
What is the interpretation?
Thanks in helping us out.

I thought binary means 1 bit ON/OFF typeYou can check mapping of logical type to native database types in "Tools>Types administration". Data Modeler comes with set of predefined logical type and their purpose is to cover all native types in supported databases.
Nothing can stop you to change predefined types if you don't like them or/and to create your own types.
In the case of "Binary" - it's introduced to cover "binary" type in MS SQL Server - it's sequence of bytes not bits or bit.
