About Delivery class

HI All,
In DDIC,in tables the Delivery class 'L' is for what purpose.Explain me about this delivery class
Thanks In Advance

Hi,
Delivery Class
The delivery class controls the transport of table data for installation, upgrade, client copy and when transporting between customer systems. The delivery class is also used in the extended table maintenance.
There are the following development classes:
A: Application table (master and transaction data).
C: Customer table, data is only maintained by the customer.
L: Table for storing temporary data.
G: Customer table, SAP may insert new data records but may not overwrite or delete existing ones. The customer namespace must be defined in table TRESC. To define the customer namespace use report RDDKOR54. You can start it directly from the table maintenance by choosing Customer namespace definition on the Attributes tab.
E: System table with its own namespace for customer entries. The customer namespace must be defined in table TRESC. To define the customer namespace use report RDDKOR54. You can start it directly from the table maintenance by choosing Customer namespace definition on the Attributes tab.
S: System table, data changes have the status of program changes.
W: System table (e.g. table of the development environment) whose data is transported with its own transport objects (e.g. R3TR PROG, R3TR TABL, etc.).
Behavior during Client Copy
Only the data of client-dependent tables is copied.
Class C, G, E, S: The data records of the table are copied to the target client.
Class W, L: The data records of the table are not copied to the target client.
Class A: Data records are only copied to the target client if explicitly requested (parameter option). It normally does not make sense to transport such data, but this is supported nevertheless to permit the entire client environment to be copied.
Behavior during Installation, Upgrade and Language Import
The behavior of client-dependent tables differs from that of cross-client tables.
Client-Dependent Tables
Class A and C: Data is only imported into client 000. Existing data records are overwritten.
Class E, S and W: Data is imported into all clients. Existing data records are overwritten.
Class G: Existing data records are overwritten in client 000. In all other clients, new data records are inserted, but existing data records are not overwritten.
Class L: No data is imported.
Cross-Client Tables
Classes A, L and C: No data is imported.
Classes E, S, and W: Data is imported. Existing data records with the same key are overwritten.
Class G: Non-existent data records are inserted, but no existing data records are overwritten.
Behavior during Transport between Customer Systems
Data records of tables having delivery class L are not imported into the target system. Data records of tables having delivery classes A, C, E, G, S and W are imported into the target system (for client-dependent tables this is done for the target clients specified in the transport).
Use of the Delivery Class in the Extended Table Maintenance
The delivery class is also used in the Extended Table Maintenance (SM30). The maintenance interface generated for a table makes the following checks:
It is not possible to transport the entered data using the transport connection of the generated maintenance interface for tables having delivery classes W and L.
Data that is entered is checked to see if it violates the namespace defined in table TRESC. If the data violates the namespace, the input is rejected.

Data class and Delivery class in ABAP Dictionary

Hi all,
I want to know the exact information about Data class and Delivery class in ABAP Dictionary
Moderator message : Search for available information. Thread locked.

As your name Suggests, there were exactly 21 rajapandian already who wanted exact information about Data class and Delivery class. Fortunately some has found the information by own and some were dumped by SAP Police.

Custom table - delivery class?

I need to create a z-table to list the email-ids that I want to notify to, in case of program errors. Should I make the delivery class of this table 'C'? And is best practise to make the data transportable? Or should my users just enter data in each system.
I am kind of confused...Could any of you please clear me on this concept of Deliver class please. Your help is very much appreciated.
thanks!

Vishnu,
Did you try? I tried these things long back and documented the behavior
May be you tried it very long back, indeed. Atleast for releases > ECC6.0 EhP3 client-independent customizing tables prompt for WB requests.
... C, G, and E will only trigger customizing requests ....
Unfortunately you're wrong! Did you check the transaction FILE? All the tables involved are of Delv. Class 'G'; but still when you try to save a logical file it asks for a WB request, ever wondered why?
Still not convinced, check [this|https://picasaweb.google.com/lh/photo/kBwoENEIkUTsGuJUTn9Q5tMTjNZETYmyPJy0liipFm0?feat=directlink]!
Suhas Saha wrote. "Customizing TRs are raised for client-dependent tables & workbench for client-independent ones!"
This was w.r.t customizing tables & not application tables, as you were talking about customizing tables in your previous response.
I can create a table with MANDT assign delivery class A or S and can trigger workbench requests on it.
I know it does. IMHO type 'A' tables are for storing master and/or transational data & it does not make sense to transport these data. For e.g., BKPF is type 'A' & not transportable, but T001 is type 'C' & transportable.
If i want to transport the data across my landscape i would make it 'C' & not 'A'.

To ragnic and other about Singleton class

Hi ragnic. Thanks for your reply. I posted the code wrong. Heres' my correct one.
I have a GUI first loaded information and the information is stored in a databse, I have some EJB classes..and my singleton class ABC has some method to access to the EJB..
so my first GUI will gather info using singleton class and later if I click on
a button in my first GUI class, will pop up another frame of another class , this class also need to class setPassword in my Singleton..
are my followign codes correctly??
iS my Class ABC a SINgleton class? thanks
Is my class ABC use as single correctly. And It is called from other classes is also correct?
I'm new to java and like to learn about Singleton class.
But I really dont' understand it clearly after reading many examples of it.
I have a project to convert my class abc to a singleton.
But I dont know how to do it.
In my class(soon will become a singleton) will have few methods that later I need to use it from another class A and class B.
I have a GUI application that first load my class A..and my class will call
class abc(singleton) to get some information from it.
and then in class A has a button, if I click on that button I will call SIngleton class again to update my password, in the singleton class has method calls updatePassword. But I dont know how to call a singleton from other class.
I have my code for them below:
1)public class ABC //attempt using a singleton
private static ABC theABC = null;
private ABC(){}
public synchronized static ABC getABC()
if(theABC == null)
theABC= new ABC();
return the ABC;

***It compiles okey but when I ran, it say "NullPointerException"
I think I call my Singleton wrong.
Please help me.thanks

1. When replying, use <reply>, don't post a new topic.
2. Implementing a singleton is a frequently asked question. Search before you post.
3. This is not a question about Swing. A more appropriate forum would be "New To Java Technology" or perhaps "Java Programming", but see point 1.
4. When posting code, keep it short. It increases the chance of readers looking at it. And in composing your shorter version for the forum, you just may solve your problem.

Customer table with delivery class 'A' asking for a request

Hello.
I've built an customer table and defined the delivery class 'A' ... Application table (master and transaction data).
Data Browser/Table View Maint. 'X' ... Display/Maintenance Allowed.
Why is this type of table definition asking for a change request to store table entries?
Please, provide some help.

Thanks ... how did i let it pass?

Need help about Vector class in java

Hello,
I have some questions about Vector class. Please see this short code:
Vector v = new Vector();
v.add(New Integer(5));
Is this the only way to add int value into vector? Performance wise, is this slow? And are there any better and faster way to add/get int element fro vector?
Thank you very much in advance.

Normally (up to Java version 1.4), that's the only way you can add an int to a Vector. The thing is that Vector can only contain Objects, and an int is a primitive, not an object. So you have to wrap the int in an Integer object.
However, Java 5 has a new feature, called autoboxing, which means that the compiler automatically wraps primitive values into objects, so that you can program it like this:
Vector v = new Vector();
v.add(5);Note, this will not make your program faster or more efficient, because the compiler translates this automatically to:
Vector v = new Vector();
v.add(new Integer(5));So in the end, the same bytecode will be produced. Autoboxing is just a feature to make life more convenient for the programmer.

Question about abstract classes and instances

I have just read about abstract classes and have learned that they cannot be instantiated.
I am doing some exercises and have done a class named "Person" and an abstract class named "Animal".
I want to create a method in "Person" that makes it possible to set more animals to Person objects.
So I wrote this method in class Person and compiled it and did not get any errors, but will this work later when I run the main-method?
public void addAnimal(Animal newAnimal)
animal.add(newAnimal);
}Is newAnimal not an instance?

Roxxor wrote:
Ok, but why is it necessary with constructors in abstract classes if we don�t use them (because what I have understand, constructors are used to create objects)?Constructors don't create objects. The new operator creates objects. An object's c'tor is invoked after the object has already been created. The c'tors job is to initialize the newly-created object to a valid state. Whenever a child object is created, the parent's c'tor is run before the child's c'tor, so that by the time we're inside the child's c'tor, setting up the child's state, we know that the parent (or rather the "parent part" of the object we're initializing) is in a valid state.
Constructor rules:
1) Every class has at least one ctor.
1.1) If you do not define an explicit constructor for your class, the compiler provides a implicit constructor that takes no args and simply calls super().
1.2) If you do define one or more explicit constructors, regardless of whether they take args, then the compiler no longer provides the implicit no-arg ctor. In this case, you must explicitly define a public MyClass() {...} if you want one.
1.3) Constructors are not inherited.
2) The first statement in the body of any ctor is either a call to a superclass ctor super(...) or a call to another ctor of this class this(...) 2.1) If you do not explicitly put a call to super(...) or this(...) as the first statement in a ctor that you define, then the compiler implicitly inserts a call to super's no-arg ctor super() as the first call. The implicitly called ctor is always super's no-arg ctor, regardless of whether the currently running ctor takes args.
2.2) There is always exactly one call to either super(...) or this(...) in each constructor, and it is always the first call. You can't put in more than one, and if you put one in, the compiler's implicitly provided one is removed.

Delivery Class Changed To A

Hi
see the doc of the delivery class
Delivery class
The delivery class controls the transport of table data when installing or upgrading, in a client copy and when transporting between customer systems. The delivery class is also used in the extended table maintenance.
There are the following delivery classes:
A: Application table (master and transaction data).
C: Customer table, data is maintained by the customer only.
L: Table for storing temporary data.
G: Customer table, SAP may insert new data records, but may not overwrite or delete existing data records. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here).
E: System table with its own namespaces for customer entries. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here.)
S: System table, data changes have the same status as program changes.
W: System table (e.g. table of the development environment) whose data is transported with its own transport objects (e.g. R3TR PROG, R3TR TABL, etc.).
Behavior during client copy
Only the data of client-specific tables is copied.
Classes C, G, E, S: The data records of the table are copied to the target client.
Classes W, L: The data records of the table are not copied to the target client.
Class A: Data records are only copied to the target client if explicitly requested (parameter option). Normally it does not make sense to transport such data, but is supported to permit you to copy an entire client environment.
Behavior during installation, upgrade and language import
The behavior differs here for client-specific and cross-client tables.
Client-specific tables
Classes A and C: Data is only imported into client 000. Existing data records are overwritten.
Classes E, S and W: Data is imported into all clients. Existing data records are overwritten.
Class G: Existing data records are overwritten in client 000. In all other clients, new data records are inserted, but existing data records are not overwritten.
Class L: No data is imported.
Cross-client tables
Classes A, L and C: No data is imported.
Classes E, S, and W: Data is imported. Exisitng data records with the same key are overwritten.
Classe G: Data records that do not exist are inserted, but existing data records are not overwritten.
Behavior during transport between customer systems
Data records of tables of delivery class L are not imported into the target system. Data records of tables of delivery classes A, C, E, G, S and W are imported into the target system (this is done for the target client specified in the transport for client-specific tables).
Use of the delivery class in the extended table maintenance
The delivery class is also analyzed in the extended table maintenance (SM30). The maintenance interface generated for a table makes the following checks:
You cannot transport the entered data with the transport link of the generated maintenance interface for tables of delivery classes W and L.
When you enter data, there is a check if this data violates the namespace defined for the table in table TRESC. If the data violates the namespace, the input is rejected.
We generally use C for customer to enter data into the table
when you change it to Application table (A) you have to regeenrate and to give the access for entering the data
see the table maintenance generator doc
table maintanance Generator is used to manually
input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under
attributes tab
2) utilities-table maintanance Generator->
create function group and assign it under
function group input box.
also assign authorization group default &NC& .
3)
select standard recording routine radio in table
table mainitainence generator to move table
contents to quality and production by assigning
it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers
this dialog box appears when you click on create
button
6) save and activate table

One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.

Change Delivery Class of ZTable

We currently have a ZTABLE that is defined as Delivery Class 'A'. In each system (DEV, QAS, PRD) we modify the table using a Table Maintenance View and SM30. We now have a requirement to enforce promotion of the Data in the table from DEV to QAS to PRD. In my experiments, Delivery Class 'C' will provide this functionality; however, I am not sure if it is possible (or advisable) to change the Delivery Class of a Table already promoted to Production.
Has anyone had any experience with changing the Delivery Class of an existing table?
I've checked online documentation for Delivery Classes; so far this has explained how to initially choose a Delivery Class, but there has been no information on changing a Delivery Class or statements stating not to change the Delivery Class of a table. In addition I have Googled "SAP Change Delivery Class", "SAP Table Class" and "SAP Delivery Class"; these searches have yielded no results that answer this question.
The other option I am looking at involves building a new table with an identical structure of the Delivery Class 'C', then changing each application to read the new table instead of the existing table.
Any help and/or opinions will be appreciated.
Thank you,
Steven Coolbaugh

Hello Steven,
Whether or not table entries can be transported does not depend upon the "delivery class".
In my experiments, Delivery Class 'C' will provide this functionality
AFAIK this won't help. If the delivery class of the table is 'C', then you have to use a customizing request to transport the entries. To make the entries transportable you have to activate the "standard recording routine" radio-button in the table maintenance generator.
Hope this helps.

I have already parsed the HTML and checked all the closing of tags and corrected the indent using Tidy and then I have applied this code so some other suggestions please

A question about Object Class

I got a question about Object class in AS3 recently.
I typed some testing codes as following:
var cls:Class = Object;
var cst:* = Object.prototype.constructor;
trace( cls === cst); // true
so cls & cst are the same thing ( the Object ).
var obj:Object = new Object();
var cst2:* = obj.constructor.constructor;
var cst3:* = obj.constructor.constructor.c.constructor;
var cst5:* = Object.prototype.constructoronstructor;
var cst4:* = Object.prototype.constructor.constructor.constructor;
var cst6:* = cls.constructor;
trace(cst2 === cst3 && cst3 === cst4 && cst4 === cst5 && cst5 === cst6); //true
trace( cst == cst2) // false
I debugged into these codes and found that cst & cst2 had the same content but not the same object,
so why cst & cst2 don't point to the same object?
Also, I can create an object by
" var obj:Object = new cst();"
but
" var obj:Object = new cst2();"
throws an exception said that cst2 is not a constructor.
Anyone can help? many thanks!

I used "describeType" and found that "cst2" is actually "Class" class.
So,
trace(cst2 === Class); // true
That's what I want to know, Thank you.

Data maintenance in a table of delivery class S

Hi,
If i have to maintain en entry in a table with delivery class S (System table, maint. only by SAP) , can i do it in any client
or only system maintenance client.
Regards,
sushant

hi
There are the following delivery classes:
A: Application table (master and transaction data).
C: Customer table, data is maintained by the customer only.
L: Table for storing temporary data.
G: Customer table, SAP may insert new data records, but may not overwrite or delete existing data records. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here).
E: System table with its own namespaces for customer entries. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here.)
S: System table, data changes have the same status as program changes.
W: System table (e.g. table of the development environment) whose data is transported with its own transport objects (e.g. R3TR PROG, R3TR TABL, etc.).
Behavior during client copy
Only the data of client-specific tables is copied.
Classes C, G, E, S: The data records of the table are copied to the target client.Classes W, L: The data records of the table are not copied to the target client.
Class A: Data records are only copied to the target client if explicitly requested (parameter option). Normally it does not make sense to transport such data, but is supported to permit you to copy an entire client environment.
Behavior during installation, upgrade and language import
The behavior differs here for client-specific and cross-client tables.
Client-specific tables
Classes A and C: Data is only imported into client 000. Existing data records are overwritten.
Classes E, S and W: Data is imported into all clients. Existing data records are overwritten.Class G: Existing data records are overwritten in client 000. In all other clients, new data records are inserted, but existing data records are not overwritten.
Class L: No data is imported.
Cross-client tables
Classes A, L and C: No data is imported.
Classes E, S, and W: Data is imported. Exisitng data records with the same key are overwritten.Classe G: Data records that do not exist are inserted, but existing data records are not overwritten.
Behavior during transport between customer systems
Data records of tables of delivery class L are not imported into the target system. Data records of tables of delivery classes A, C, E, G, S and W are imported into the target system (this is done for the target client specified in the transport for client-specific tables).
Use of the delivery class in the extended table maintenance
The delivery class is also analyzed in the extended table maintenance (SM30). The maintenance interface generated for a table makes the following checks:
You cannot transport the entered data with the transport link of the generated maintenance interface for tables of delivery classes W and L.
When you enter data, there is a check if this data violates the namespace defined for the table in table TRESC. If the data violates the namespace, the input is rejected.
Hope this information is useful to you.

Delivery class

which purpose we use DELIVER CLASS plz tell me in
general terminalogy.not in technical

Hi,
Delivery class is the one which controls the table, while upgrading, maintaining and copying.
The delivery class controls the transport of table data when installing or upgrading, in a client copy and when transporting between customer systems. The delivery class is also used in the extended table maintenance.
There are the following delivery classes:
A: Application table (master and transaction data).
C: Customer table, data is maintained by the customer only.
L: Table for storing temporary data.
G: Customer table, SAP may insert new data records, but may not overwrite or delete existing data records. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here).
E: System table with its own namespaces for customer entries. The customer namespace must be defined in table TRESC. (Use Report RDDKOR54 here.)
S: System table, data changes have the same status as program changes.
W: System table (e.g. table of the development environment) whose data is transported with its own transport objects (e.g. R3TR PROG, R3TR TABL, etc.).
Behavior during client copy
Only the data of client-specific tables is copied.
Classes C, G, E, S: The data records of the table are copied to the target client.
Classes W, L: The data records of the table are not copied to the target client.

Question about multiple class files

I just started learning JAVA a couple of days ago and the first program I wrote had two classes in one file. here is the program :
class fib_num {
public int value;
public boolean is_even;
class Fibonacci {
/** Print the Fibonacci sequence for values < MAX and mark even numbers with an asterick */
private static final int MAX = 50;
private static final String Title = "The Fibonacci sequence for values less than " + MAX + ":";
private static fib_num[] fib = new fib_num[MAX];//This is actually an array of object
//references to objects of the fib_num class
public static void main(String[] args) {
System.out.println(Title);
//We must initialize each element of the array also !!!!
for (int i = 0; i < fib.length; i += 1) {
fib = new fib_num();
int lo = 1, hi = 1;
fib[0].value = lo;
fib[0].is_even = false;
fib[1].value = hi;
fib[1].is_even = false;
for (int i = 2; i < fib.length; i += 1) {
//create the next Fibonacci number and then save the previous Fibonacci number
hi = lo + hi;
lo = hi - lo;
fib.value = hi;
//now indicate if the Fibonacci number is even/odd
if (fib.value % 2 == 0) {
fib.is_even = true;
}else {
fib.is_even = false;
print (fib);
//This method prints an array of Fibonacci numbers
public static void print(fib_num[] array) {
if (array == null || array.length == 0)
throw new IllegalArgumentException();
String mark;
for (int i = 0; array.value < MAX; i += 1) {
if (array.is_even) {
mark = "*";
}else {
mark = "";
System.out.println((i + 1) + ": " + array.value + mark);
I ran the program and everything went fine. But today I started to write another program with two classes. However the file will not compile and I get an error about interfacing or something. here is the program:
Note: it's not nearly complete.
class enumerate {
//print out all permutations of a list of integers
public static final int MAX = 4;
public static int[] initialize(int[] nums) {
for (int i = 0; i < nums.length; i++) {
nums = i + 1;
return nums;
public static void print(int[] nums) {
for (int i = 0; i < nums.length; i++) {
System.out.print(nums);
System.out.println("");
public static void swap (int[] nums, int i, int j) {
int temp = nums;
nums = nums[j];
nums[j] = temp;
public static void main (String[] args) {
int[] list = new int[MAX];
list = initialize(list);
PermutationGenerator x = new PermutationGenerator(5);
// Systematically generate permutations.
import java.math.BigInteger;
public class PermutationGenerator {
private int[] a;
private BigInteger numLeft;
private BigInteger total;
// Constructor. WARNING: Don't make n too large.
// Recall that the number of permutations is n!
// which can be very large, even when n is as small as 20 --
// 20! = 2,432,902,008,176,640,000 and
// 21! is too big to fit into a Java long, which is
// why we use BigInteger instead.
public PermutationGenerator (int n) {
if (n < 1) {
throw new IllegalArgumentException ("Min 1");
a = new int[n];
total = getFactorial (n);
reset ();
// Reset
public void reset () {
for (int i = 0; i < a.length; i++) {
a = i;
numLeft = new BigInteger (total.toString ());
// Return number of permutations not yet generated
public BigInteger getNumLeft () {
return numLeft;
// Return total number of permutations
public BigInteger getTotal () {
return total;
// Are there more permutations?
public boolean hasMore () {
return numLeft.compareTo (BigInteger.ZERO) == 1;
// Compute factorial
private static BigInteger getFactorial (int n) {
BigInteger fact = BigInteger.ONE;
for (int i = n; i > 1; i--) {
fact = fact.multiply (new BigInteger (Integer.toString (i)));
return fact;
// Generate next permutation (algorithm from Rosen p. 284)
public int[] getNext () {
if (numLeft.equals (total)) {
numLeft = numLeft.subtract (BigInteger.ONE);
return a;
int temp;
// Find largest index j with a[j] < a[j+1]
int j = a.length - 2;
while (a[j] > a[j+1]) {
j--;
// Find index k such that a[k] is smallest integer
// greater than a[j] to the right of a[j]
int k = a.length - 1;
while (a[j] > a[k]) {
k--;
// Interchange a[j] and a[k]
temp = a[k];
a[k] = a[j];
a[j] = temp;
// Put tail end of permutation after jth position in increasing order
int r = a.length - 1;
int s = j + 1;
while (r > s) {
temp = a[s];
a[s] = a[r];
a[r] = temp;
r--;
s++;
numLeft = numLeft.subtract (BigInteger.ONE);
return a;
I thought the error had somethin to do with only having one class per .java file since the compiler creates a .class file. But how come my first program had two classes and it was OK. Is it b/c the second class was merely a collection of fields, almost like a simple struct in C?
Any help would be appreciated. Thanks

Move the import java.math.BigInteger line to the start of the file.
Use the "[ code ] [ /code ]" tags around your code when you post, it makes reading it a lot easier.
