BAPI Overloading and overriding

Hi Friends,
I just want to know Whether we can use BAPI Overloading and overiding concept is possible in BAPI?
Regards
Dinesh

Hello,
As far as I understand It is not possible but can you please explain little bit more about the requirement so we may think of some alternative.
Enjoy SAP!

What's the difference between "overloading" and "overriding" in Java

What's the difference between "overloading" and "overriding" in Java

hashdata wrote:
What is the real-time usage of these concepts...?Overriding is used when two classes react differently to the same method call. A good example is toString(). For Object it just returns the class name and the identityHashCode, for String it returns the String itself and for a List it (usually) returns a String representation of the content of the list.
Overloading is used when similar functionality is provided for different arguments. A good example is [Arrays.sort()|http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#sort(byte%5B%5D)]: all the sort() methods do the same thing (they sort arrays), but one sorts byte-arrays, another one sorts int-arrays, yet another one sorts Object-arrays.
By the way, you almost certainly mean "real-world" usage. "real-time" (and thus "real-time usage) means something entirely unrelated to your question.

Overloading and Overriding

Why do we need Overloading and Overriding?

EJP, I'm just curious to know why you mention "*Overloading gives us the power to call a single method and pass it different parameters and the compiler at runtime decided which suitable method to call*" as a wrong answer.Because it is a wrong answer. The action occurs at compile time, not at runtime. The compiler isn't even present at runtime, by definition, so the statement is not just wrong but a contradiction in terms.
Is there any other reason for having overloading in java?The statement isn't a reason at all. It's just a definition, and an incorrect one, of what method overloading is. A definition is not a reason.
So why you're asking me for another reason when there hasn't been one provided at all in the entire thread, other than by me, is a complete, utter, and baffling mystery.
You seem to have the same problem ram has, of confusing 'what' with 'why', and of confusing definitions with reasons. One is bad enough, please let's not have two of you.

OO:overloading and overriding in tandem..Interesting one

Assume Dog IS-A Animal
class test {
public static void main(String[] args){
Animal a = new Dog();
foo(a);
void foo(Dog d){
d.printme();
void foo(Animal a){
a.printme();
}//end of class test
class Animal{
void printme(){
System.out.println("i am in animal");
}//end of class animal
class Dog{
void printme(){
System.out.println("i am in Dog");
}//end of class dog
Question:what will it print and explain how briefly u arrived at that result? (I assume u fix some obvious compile time errors(missing ; etc) as this is just a rough snippet)
NOTES-----------
1.Overloading has to do with reference type
2.Overriding has to do with the object to which it actually points

ok mlk..really sorry for being so naive.I sometimes don't clearly express my doubt. I jus got a doubt in my mind regarding overriding + overloading and i constructed a sample example as a concept(not actual code).
Here's the full fledged program..it compiles fine.And IS-A is perfectly satisfied in this case.
class Animal{
void printme(){
System.out.println("In Animal");
class Dog extends Animal{
void printme(){//overriding the Animal printme() method
System.out.println("In Dog");
public class TestDog {
void foo(Animal a){
a.printme();
void foo(Dog d){
d.printme();
public static void main(String[] args) {
Animal a = new Dog();
TestDog t = new TestDog();
t.foo(a); //method overloading
And it prints In Dog..as expected.Got it.Thanks.

Difrence bitween overloading and overriding

Plese give the definition & example for polymorphism

Polymorphism is of two types
1) static or design time polymorphism
2) dynamic or run time polymorphism
example for design time polymorphism is overloading (i.e) a method with same name shares diff signatures
For eg: arithmetic(int,int)
arithmetic(int,int,int)
example for run time polymorphism is overriding (i.e) a method with same name exists in both parent class and child class.
At run time it will be decided which method to call based on the object which calls it
Hope this clarifies yr query

Difference between OVERLOADING and OVERRIDING??

Hi guys,
can you please exaplain me difference between Overloading & Overriding with example?
Thanks,
JaxNa

Here is the example of overriding :
/* PARENT CLASS */
package com.example.supreclass {
     public class parentClass {
          public function parentClass() {
          public function fromParent(myString:String):void {
               trace("Output :", myString);
/* DERIVED CLASS */
package com.example.supreclass {
     public class myExample extends parentClass {
          public function myExample() {
          /* Override the method */
          override public function fromParent(outputStr:String):void {
               super.fromParent(outputString);
               trace("Override example");
Overriding means redefining the inherited method (the parent method still can be invoked using 'super', as shown in example )
These links should give you some idea on these :
Overriding : http://www.kirupa.com/forum/showthread.php?p=1896981
Overloading means having many functions with same name but each differs by parameters it takes (either by data type or number of parameters passed) and return value.

About overloading and overriding

I hava a Java code like this:
class Homer {
float doh(float f) {
System.out.println("doh(float)");
return 1.0f;
char doh(char c) {
System.out.println("doh(string)");
return 'd';
class Bart extends Homer {
float doh(float f) {
System.out.println("doh(float)");
return 1.0f;
class Hide {
public static void main(String[] args) {
Bart b = new Bart();
b.doh('x');//compiler error in this line
b.doh(1);
b.doh(1.0f);
An error was ocurred:reference to doh is ambigous
Who can told me why?

andy.g
you are wrong!
you cannot undertand what is the different between
overlaoding and overiding!sorry for the wrong answer.
the point is the super-class's method with most specific signiture has the same priority as the sub-class's method that could match(not exactly the same, but can be promoted, like char to float) the signiture during method binding/finding. java always put the current class's method at the first place, but when a method in super-class is more specicif in signiture, the compiler can't determin which one to use.
actually, there is nothing related to overriding in this case, e.g.:
class A{
char method(char c){.....}
class B extends A{
//nothing's been overrided
float method(float f){......}
public static void main(String[] args){
B b = new B();
b.method('c'); //compiler error.
}so it is definetely a priority's problem, the super class's methods do not have the same prority as the sub-class's.

Overloading and bla extends bla

if class A extends class B and they have both got the same name on a method but different arguments does his make it overloading still or is it overriding?thanks in advance.

is it only overloading because they extend each other
or would it be anyway?It's just overloading because you have a class that has two methods with the same name.
and if the arguments where the
same would it still be overloading?No, that would be overriding, and only if that method is inherited.
sorry im asking so
much but i'm having trouble understanding the whole
overloading and overriding situations when its
extending a class is involved,does it make a
differance?thanksYes, it does, to overriding. X defines an implementation that you want to change. If Y doesn't inherit it, there is nochting to change. You'd just be implementing yet another method.

Can we use overload and overwrite concept in OO-abap

CLASS zl_lcl_vehicle DEFINITION.

Overloading means changing signature as well as implementation of a method.
Overriding is changing only implementation of method with signature unchanged.
From ABAP perspective, only the CONSTRUCTOR method can be overloaded in a subclass i.e both the signature and implementation can be adapted in subclass.
Any other method can't be overloaded. It can only be redefined/overridden i.e implementation changed with signature unchanged.
In ABAP there is something called a redefinition.
When you inherit a class from a super class, you can redifne a method. You cannot chnage the signature( Interface) of the method. It will remain the same as that of the super class.You must redefine a method in the same visibility section in which it appears in the superclass.
Eg.
CLASS C_SUPER_CLASS DEFINITION .
PUBLIC SECTION.
METHODS: DRIVE ,
STOP.
PROTECTED SECTION.
DATA SPEED TYPE I.
ENDCLASS.
CLASS C_SUPER_CLASS IMPLEMENTATION.
METHOD DRIVE.
SPEED = 0.
WRITE: / 'Bike speed =', SPEED.
ENDMETHOD.
ENDCLASS.

Differences between bapi's and bdc

Hi Frendz,
What are the most imp differences between BAPI's and BDC ?
Points for sure...
Thanks in advance
Vijaya

Hi Vijaya,
A few inputs from net
BAPI is used only when it is available for the particular transaction like Delivery Sales order. but BDC can be used for any
transaction which have screen and fields.
BAPI is directly updated the database instead BDC run through the screen flow.
So BAPI can't handle all the flow logic checking and enhancement put by programmer to faciliate the user requirement.
BAPI is a higher end usage for tranfering the data from SAP to non-SAP and vice-versa. for ex: if we are using VB application,where in that we want to connect to SAP and retireve the data,and then change and update the data in SAP for that purpose we can use that.
Apart from that, we can also use it for Uploading/Downloading the data from SAP to Non-SAP like BDC, provided we have an existing BAPI for that.
BAPI function modules will also do all the checks required for data integrity like Transactions for BDC.
There is one more advantage using BAPI instead of BDC.
When we go for upgradation, there might be pozzibility to change the screen elements for transactions depending on the requirement. In that case,our BDC pgm may or may not work (depending on the screen changes they have made). Unless and until we prepare new BDC we cant use the old BDC pgm. But in BAPI, SAP promises that they are going to keep the old BAPI and for new functionality they will provide an upgraded BAPI. Until we write a new BAPI pgm, we can use the exisitng BAPI pgm.

Extending classes and overriding methods

If I have a class which extends another, and overrides some methods, if I from a third class casts the extending class as the super class and calls one of the methods which gets overrided, is it the overrided method or the method of the superclass which get executed?
Stig.

Explicit cast can't enable the object to invoke super-class's method. Because dynamic binding is decided by the instance. The cast can just prevent you from using methods only defined in sub-class, but it does not let the object to use super-class's method, if the method's been overrided. Otherwise, the polymophism, which is one of the most beautiful feature of Object-Oriented thing, can't be achieved. As far as I know, the only way to use super-class's method is the super keyword in the sub-class, and seems no way for an object to do the same thing (I may wrong, since I haven't read the language spec).
here's a small test:
public class Test {
public static void main(String[] args){
A a = new B();
a.method();
((A)a).method();
class A{
public void method(){
System.out.println("A's method");
class B extends A{
public void method(){
System.out.println("B's method");
The output is:
B's method
B's method

Server Overloaded and Warning Status

I have a WebLogic cluster, includes 3 Managed Server running on 2 separate machines (Each has 16Gb Ram and 8 CPU - Sun Sparc). Each start with parameters
Starting WLS with line:
/usr/jdk/instances/jdk1.6.0/bin/java -server -Xms1024m -Xmx2048m -XX:MaxPermSize=128m
Some time ManagedServers have status "OverLoaded" and "Warning". When that happened , I stop and start server and server status return to OK.
Checking the status with "prstat" command, I saw that java process used just from 1Gb Ram to 2Gb Ram and CPU is under 3%, very little CPU used
What I have to do to make server return to OK status without restart?
And how to make server running with OK status everytime?
And How many Managed Server can I create on each machine with that hardware?
Thank you!

What I have to do to make server return to OK status without restart?Maybe stop some or all applications can be usefull.
And how to make server running with OK status everytime?You must tuning the enviroment, maybe should adjust JVM parameters passed to weblogic server, check thread pools, etc. For Sun HotSpot JVM, you can use -XX:+AggressiveHeap option for throughput applications, give it a try.
See [WebLogic Server Performance And Tuning|http://download.oracle.com/docs/cd/E13222_01/wls/docs92/perform/index.html]
And How many Managed Server can I create on each machine with that hardware?This decision depends on applications you want run, weblogic resources required, how many clients will be attended, and so on. If your weblogic server using 8GB achieves the goal, then you can setup another instance using the remaining available, and so on.
I hope this helps.

Re:Bapi's and Bdc's

hi friends,
Iam new to Bapi's and Bdc's plz tell me which sites are good for learning and i also want some realtime examples or codes.
Thanks in advance.

Hi
what is BAPI?
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

Bdc to Bapi
The steps to be followed are :
1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
[for VA01 use BAPI_SALESORDER_CREATEFROMDAT2]
2. Create a Z program and call the BAPi (same as a Funtion module call).
2. Now, if you see this BAPi, it has
-> Importing structures.
eg: SALESDOCUMENT: this will take the Sales order header data as input.
-> Tables parameters:
eg: ORDER_ITEM_IN: this will take the line item data as input.
Note :
Only specify fields that should be changed
Select these fields by entering an X in the checkboxes
Enter a U in the UPDATEFLAG field
Always specify key fields when changing the data, including in the checkboxes
The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
Maintain quantities and dates in the schedule line data
Possible UPDATEFLAGS:
U = change
D = delete
I = add
Example
1. Delete the whole order
2. Delete order items
3. Change the order
4. Change the configuration
Notes
1. Minimum entry:
You must enter the order number in the SALESDOCUMENT structure.
You must always enter key fields for changes.
You must always specify the update indicator in the ORDER_HEADER_INX.
2. Commit control:
The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
For further details... refer to the Function Module documentation for the BAPi.
Bapi to VB(Visual Basic)
Long back I had used the following flow structure to acheive the same.
Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
You need to have com4abap.exe
If com4abap is installed you will find it in sapgui installatin directory , C:Program FilesSAPpcsapguiRFCSDKcom4abap.
else refer OSS note 419822 for installation of com4abap
after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
for setting up com4abap and rfc destination please refer to the documentation for com4abap.

BDC
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.
