Help needed in Logical Database Programming

Hello Gurus,
I am working on a Report on ASSET ACTIVITY BY DATE RANGE .
The program is copied from std. program S_ALR_87011990.
The above std. program displays for the whole financial year. This is modified for a particalar period range in the new leveraged program.
My question is in the below code.
We are fetching data using LDB ADA. The statement "GET anlcv" works fine here, I mean Sy-subrc is 0 and anlcv structure has some data in it.
When it comes to statement "GET anepv" in the below code, we are not getting any data into that structure and sy-subrc NE 0. Then it is skipping all the get statements and directly going to statement " PERFORM abga_simulieren.".
My logic lies in between this Get statement and the perform statement. When i see it in debugging mode my statement is not executed at all.
What needs to be done. Please anyone help me.
GET anlcv.
CHECK select-options.
MOVE anlcv TO sav_anlcv.
GET anepv.
CHECK select-options.
Nur Bewegungen des Jahres des Berichtsdatums durchlassen.
CHECK anepv-bzdat GE sav_gjbeg.

1) delete line CHECK anepv-bzdat ge sav_gjbeg.
2) test with an asset , which has movements (purchases) in your intervall so_bzdat.
otherwise post a movement (e.g. transaction type 100) with tcode abzon

Need of logical database

Hi,
Can any one briefly explain what is the need of Logical database?
In which case , abapers r going for logical database?
regards,
Pooja

Hi Pooja,
A logical database is a special ABAP/4 program which combines the contents of certain database tables. You can link a logical database to an ABAP/4 report program as an attribute. The logical database then supplies the report program with a set of hierarchically structured table lines which can be taken from different database tables.
GET will fetch the table data immediately
GET LATE
In the LDB when you define the table structure in hierarchy, first it will fetch the higher node data and then all the below node tables data and comes to a second record in the top node table. for this GET Late is used.
You can create any number of primary keys in a table
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic.

Hi,
think inthis program in the function module REUSE_ALV_FIELDCATALOG_MERGE
in exporting parameter you are using -->
I_INTERNAL_TABNAME = <itab_name>
this <itab_name> is not like any physical structure .So make a structure through SE11 like <itab_name>.
u have to create a structure in SE11 with the fields, and then pass that structure into the REUSE_ALV_FIELDCATALOG_MERGE , in the parameter
I_internal_tabname = ' structure name '.
even though u create a structure, u need to pass it to the table parameter.
then it will work.
Otherwise manually build the fieldcatalog.
find the following code as an example.
DATA : l_pos TYPE i VALUE 1.
ist_fieldcat-fieldname = 'POSID'.
ist_fieldcat-tabname = 'IT_FINAL'.
ist_fieldcat-outputlen = 24.
ist_fieldcat-col_pos = l_pos.
ist_fieldcat-ddictxt = 'L'.
ist_fieldcat-key = 'X'.
ist_fieldcat-seltext_l = 'Appropriation Request Number'.
APPEND ist_fieldcat.

I had linked the database using ODBC and it works well..the only problem is that when i click the "vote" button of the selected JRadioButtons..It doesn't add to my access database file.It will have a lot of errors in the command line.But for the compiling and execuation it works fine.
for my access database..I had created a table called "poly" and I had included all the 5 names of the polythenic inside too with fieldnames=nyp,sp,tp,rp,np and data type all to Number.
My reason behind this is to allows the database to read in values from the radiobutton and once the user who click the vote button will store as 1 and by clicking the second time it will auto add to 2.

Some help needed for shopping calculator program

Hi. I would like to thank you in advance for helping me. At the moment I am pretty much stuck. I don't know how to add the input using 'while loop'. This is what I'm suppose to do:
Write a program called ShoppingCalculator.java that allows the user to enter the prices of several items they have bought and then tells them the total amount. The user can enter the prices for as many items as they want, until they click Cancel. The program should then output the total amount they spent, in a message dialog box. Use pounds for all the amounts.
So far I have written:
import javax.swing.JOptionPane;
public class ShoppingCalculator
    public static void main(String[] args)
            boolean done = false;
            double amount;
            String input;
            while (!done)
                    input = JOptionPane.showInputDialog("Enter the amount you spent on the next item:");
                    amount = Double.parseDouble (input);
            if (done = true)
                    JOptionPane.showMessageDialog (null, "You spent a total amound of £" + amount );
}Sorry if the code doesn't make much sense cause I've been changing the code around so many times that.
At one point when I was playing around with the code, I manage to make the input dialog loop nicely but when I pressed cancel, the message dialog only output the last input I put in. What I'm really stuck here is I need to know how to add the input when using 'while loop' and is it correct to use the IF Statement on this program. Please give me some advice on how to and I will try to work on it again.

Ok. I have edit the code and this is what it looks like:
import javax.swing.JOptionPane;
public class ShoppingCalculator
    public static void main(String[] args)
            boolean done = false;
            double amount;
            String input;
            double total = 0;
            while (!done)
                    input = JOptionPane.showInputDialog("Enter the amount you spent on the next item:");
                    amount = Double.parseDouble (input);
                        if (input == null)
                                    total = total + amount;
                                    JOptionPane.showMessageDialog (null, "You spent a total amound of " + total );
}I created another variable (total) and it even compiled. The only problem I have now is the message dialog wouldn't show at the end. When I press cancel and nothing happen. This is what I get on my output command window:
Exception in thread "main" java.lang.NullPointerException
at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:991)
at java.lang.Double.parseDouble(Double.java:510)
at ShoppingCalculator.main(ShoppingCalculator.java:23)
Java Result: 1
Anything that isn't right here?

Selection screen in Logical Database programming

In my Executable program,i have used 'GET PERNR' .
but i don't need the standrd selection screen as such.I want to modify the std selection screen . Instead of allowing user to select the PERNR's , i want to set their PERNR's by default .
Advance Thanks .
J

You have write this in your INITIALIZATION and AT SELECTION-SCREEN OUTPUT events.
In your INITIALIZATION event, default the PERNR to the PERNR of the employee who is running it.
In the AT SELECTION-SCREEN OUTPUT, add the code to make it display only as follows.
LOOP AT SCREEN.
IF SCREEN-NAME = PERNR.
SCREEN-INPUT =0.
MODIFY SCREEN.
ENDIF.
ENDLOOP.

Help Needed on a java program

I am very new to java and our teacher has given us a program
that i am having quite a bit of trouble with. I was wondering if anyone could help me out.
This is the program which i have bolded.
{You will write a Java class to play the TicTacToe game. This program will have at least two data members, one for the status of the board and one to keep track of whose turn it is. All data members must be private. You will create a user interface that allows client code to play the game.
The user interface must include:
� Boolean xPlay(int num) which allows x to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
� Boolean oPlay(int num) which allows o to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
� Boolean isEmpty(int num) will check to see if the square labeled by num is empty.
� Void display() which displays the current game status to the screen.
� Char whoWon() which will return X, O, or C depending on the outcome of the game.
� You must not allow the same player to play twice in a row. Should the client code attempt to, xPlay or oPlay should print an error and do nothing else.
� Also calling whoWon when the game is not over should produce an error message and return a character other than X, O, or C.
� Client code for the moment is up to you. Assume you have two human players that can enter the number of the square in which they want to play.
Verifying user input WILL be done by the client code.}

This is the program which i have bolded.Hmmm, that doesn't look like any programming language I've ever seen. I guess you have the wrong forum here, because it isn't Java.
That looks like a natural-language programming language that directly understands a homework assignment. Either that, or you really did just post the assignment. You wouldn't have done that though, right?

Help needed with a paint program

Hi, I am writing a program to work as a paint application. I have all the necessary buttons. One of my buttons needs to be able to add a small image to the painting frame by clicking the mouse onto the screen...for example, to display a picture of a house, I click the house button which then puts my house picture onto the scribble panel wherever I click the mouse. My problem is that I am new to java and I am stuck on how I can do this. I have put all the code on here which I have. If any one knows the code which I can add to make this work I would very much appreciate it as it is driving me insane!
Many thanks....

The code posted just sends any data it receives back to the person who sent it. To get it to work there, you probably should flush after the println. I believe your mother taught you always to flush. It seems you have forgotten.

Help needed with a chat program

Hi everyone! i'm busy with a client/server chat program. I'm really stuck because i can't seem to get the messages from one client to show on the other client's screen.
If one client sends a message to another client, the server receives the message, but the second client does not receive the message.
Here is the server code that sends messages to the clients:
BufferedReader incomeReader = null;
PrintWriter outWriter = null;
try {
     incomeReader = new BufferedReader(new InputStreamReader (incomingSocket.getInputStream()));
outWriter = new PrintWriter(incomingSocket.getOutputStream(),true);
}catch (Exception e) {
          System.out.println("error handling a client: " + e);
System.exit(-1);
line = incomeReader.readLine();
textArea.append(line + "\n");
outWriter.println(line);
The server is suppose to put the message it receives on the text area on the server screen, and then send the message to all clients connected to it.
I hope somebody will be able to help me...

Help needed on where install program places UPK Library

I installed UPK Developer (Version 11.1) on my laptop in order to get familiar with it before an upcoming project. However, I cannot get past the Add Profile dialog box as I don't know where the Install program placed the Library on my computer. Any help would be appreciated. Thanks.

Do you remember if you installed UPK as a single user or multi-user configuration? The multi-user setup requires the pathname to a library on an external server when you launch UPK. You might want to reinstall UPK and make sure you chose the single user option. I'm not 100% sure, but it sounds like that might be the issue.

Help needed on a chat program..............

Somebody please help me. I can't seem to get my client/server program to work well. The problem is that when a client sends a message to another client, the other client doesn't receive that message. Instead, the server and the client that sent the message are the ones that receive the message.
Here is the server code that processes the messages:
BufferedReader incomeReader = null;
PrintWriter outWriter = null;
try {
incomeReader = new BufferedReader(new InputStreamReader(incomingSocket.getInputStream()));
outWriter = new PrintWriter(incomingSocket.getOutputStream(),true);
}catch (Exception e) {
System.out.println("error handling a client: " + e);
System.exit(-1);
line = incomeReader.readLine();
outWriter.println(line);
outWriter.flush();
Well, i hope somebody will be able to help....

incomeReader = new BufferedReader(new InputStreamReader(incomingSocket.getInputStream()));
outWriter = new PrintWriter(incomingSocket.getOutputStream(),true);Quite what you programmed. "incomingSocket" sends the message and gets it back.

Help needed, new to java programming

hi,
I have craeted a Frame with some check boxes and button called "button1".
Can anyone tell me how can i count the number of CHECKED check boxes so that when i press the button1 in my code it should display the result as number of checked check boxes divided by total number of check boxes. It should display the result in a textfield here RESULT textfield in my code
Thanks in advance ...i am sending the code i have written so far....
public class Frame extends java.awt.Frame {
 /** Creates new form Frame */
 public Frame() {

 setSize(600, 600);
 /** This method is called from within the constructor to

Two problems in the code you repost-ed:
1. It lacks import statements.
2. There is an extraneous } at the end of the button1ActionPerformed method.
Correct them and it'll work fine. Posting the full source code:

I can see from the code that the GUI was generated by a tool. Since you're new to Java programming, I'd recommend ditching the tool and writing everything by hand, otherwise you're not learning much. It's just like when you're learning proofs in Maths, where you start with first principles before making use of the proofs on their own.
Also, it'll help tremendously if you could spend some time going through the Java Tutorial (http://java.sun.com/docs/books/tutorial/). It's free, and I find it very useful.
Hth.

Help needed to trace a program ...

Hi,
I am trying to reach the program which actually generates the PO from ME21N/ME22N. Could you please help me trace or let me know the program name ??
Once PO is created and if I have the print option set in the "Messages", the PO is printed to the printer. I want to trace after the point, the PO is saved in the table. i.e. from the time PO output is assembled for printing. also i want to know if its in .txt format ??
thanks

Hi Rad Sha,
your program should be run in background, if you want to look that, you have to activate the background debuging.
To do that, start a ME22N/ME21N, put /hs (in the field for the transaction). Save your PO, that will go in debuging. Use the button Setting, select the background debugging and press save.
After this you could press the key F8.
You will have a new window that will appear, in debug mode. This window correspond of the background.
