Value only one time displayed

Hello all,
one question: I have a report region. In one column a value is several times among each other. What can I do, the same values display only one time?
Thanks a lot!
Regards
Daniel

Daniel,
Not sure if I have exactly understood your question but are you talking about Break Formatting? So that a report will display like:
CATEGORY | PRODUCT
Computer - Monitor
- Keyboard
- Mouse
Car - Wheel
- Engine
- Gears
instead of:
Computer - Monitor
Computer - Keyboard
Computer - Mouse
Car - Wheel
Car - Engine
Car - Gears
If so, you'll want to investigate Break Formatting in your Report Attributes or look in the Help for more details on this.
Sorry if that's not what you meant...

Your code has very little to do with what you are describing.
There is no button with "switch until released" mechanical action. (OK is switch when released, stop is latch when released)
A case structure always "works". Are you saying that it should execute e.g. the true case only once whenever the outer case goes from false to true??
Your inner case goes true more than once per run of the program (whenever the OK goes true). If it should really only work once overall, use the "first call?" primitive. You need to formulate the problem using less ambiguous words.
There is no obvious starting state for the boolean that you read via local variables. How do you ensure that it start with a known value? Does it matter?
You seem to entirely deal with integers, so why are you using floating point representation for the numerics?
What is the purpose of the orange numeric indicator. Is it just a kludge for your logic or does its value mean anything?
Why does your loop not contain any wait?
At this point, you should learn about shift registers. It would eliminate all your local variables.

MVC: update only one time

Hi,
suppose I've this model class:
public class MyClass extends java.util.Observable {
     public MyClass(){}
     //get methods
     //set methods
     private int x;
     private int y;
     private int z;
     private int t;
     private int s;
}Now I want that, when I use more than one set method, observers are notified only one time.
That is,
if I have this calls:
MyClass obj = new MyClass();
obj.setX(1);
obj.setY(2);
obj.setZ(3);
obj.setT(4);
obj.setS(5);I want that the update method isn't called five times, but only one time.
I can't add setChanged() and NotifyObservers() in only one of the set method,
because I 'm interesting in knowing when the model has been modified.
I thought of adding a new set method like this:
setModified(){
   setChanged();
   notifyObservers();
}so, every time I want to notify observers, I run this method.
But, I want to know:
Is this the correct way to do?
Thank you in advance.
MargNat

No,
the five values doesn't always change all at once.
I can have this code in one class:
obj.setX(45);
obj.setY(46);and in another class this:
obj.setX(45);
obj.setZ(345);
obj.setT(345);I simply don't want the observers are called many times.
the values are indipendent among them, I don't want to have only one set method for them;
this isn't an object oriented approach.
Practically, I want to know where exactly must be placed setChanged() and notifyObservers() methods.
In all model methods?
In a specific method I can call every time I want to update?
I must call setChanged() and notifyObserver() directly, as example, like:
obj.setChanged()
obj.notifyObservers?
Thank you again.

Custom Ringtones ring only one time ( Please Report to Xperia Z2 Developers )

I buy Z2 last weak, before it i was using Z1.
Both devices have one error in their Firmware and that is about ringtone.
no matter whatever the custom ringtone you set for ringtone notification its ring only one time and then only vibrate.
For example i set a tone which is 12 second tone so when ever some one call me after 12 second the ringtone did not repeat.

Only one time Froforma Invoice

Hi All,
Is there is any check for Froforma Invoice that should come only one time ...when they will creat the forforma invoice the system should give a error massage that " the Proforma Invoice is already created" and that is error massage ...
Thanks in advance ....
Regards,
Abhijit

Hi Samier,
Actually the requirement is they will allow the user to take only one time Proforma invoice ...But in SAP standard u can take save the Froforma invoice as many times as the user want ...In item category the completion rule will not work ....because i want to check the delivery document should be refence for two times once for F2 and again for F8.As if we want to creat the billing doc for 2 time the system shows this billing has already been done ...that is also applicable for F8....

Abhijit......................

Hi, Brad,
I appreciate your help! I am a beginning Java student, so this code is more complex than what I can handle alone.
A copy of the compilation error is at the very bottom of this message.
I added " int chkValues[]; " to the beginning of your code, and then inserted the whole code snippet to the detail (Invoice) page as shown:

Driver DriverrsBeachwear = (Driver)Class.forName(MM_connBeachwear_DRIVER).newInstance();
Connection ConnrsBeachwear = DriverManager.getConnection(MM_connBeachwear_STRING,MM_connBeachwear_USERNAME,MM_connBeachwear_PASSWORD);
int chkValues[];
StringBuffer prepStr=new StringBuffer("SELECT ID, Item, Color, Size FROM Beachwear WHERE ID=");
for(int x=0;x<chkValues.length;++x){
prepStr.append( chkValues[x] );//using an x instead of an i
if((x+1)<chkValues.length){//another iteration
prepStr.append(" OR ID=");
}//end if
}//end for loop
PreparedStatement StatementrsBeachwear = ConnrsBeachwear.preparedStatement(prepStr);

Report generation only one time successfull

Hi @all,
we are facing the problem that the report generation process is only working one time successfully, the next time it ends with error. After restarting the service on the WWI server the next generation is successfull, but the second one will be "Error" again.
Does anybody faced this issue before and can provide a solution?
Thank you in advance for all contributions!!!
Best regards,
Christoph
PS: in the meantime we created the respective service again on the server - no result, still only one successfull run at a time.
Edited by: Christoph Giehl on Sep 6, 2011 5:18 PM

Hello Christoph
we never have had similar problems. May be these hints might help:
a.) check wich generation server is used during the generation and if any of the potential servers "stop" (WWI process does not proceed etc as explained by you).
b.) check if "report from template" works (assuming that use use the "old" fashioned client WWI version) => if this works than there might be a problem with SAP <=> connection (RFC) ...
c.) check please if only this WWI report (more precisely combination of generation variant and language) gives result to the "crash" of WWI process and no other one => in this case you should check WWI template
Reading you explanation I assume:
1.) there was no change in SAP set up
2.) there was no change in WWI set up (number of servers, WWI version etc.)
and we are talking (??) about a new generation variant/language combination which has never been used before (?).
With best regards
C.B.
PS: Check Marketplace. You will fond there an OSS note called "WWI Cookbook" and furthere related OSS notes poviding FAQs etc. regarding WWI topics.

SCORM package view only one time

Hello from Italy
I would like to know if I can create scorm packages that can be displayed ONLY once time by a user. In this scenario,At the end of the player content will be inaccessible.
Thanks in advance

If you are using STRUTS and you do refresh a .jsp file, probably that jsp file is using resources located in some scope that was filled during action execution, if you refresh tha page without making sure the action is being called, the .jsp will addess inexisting data is some scope.
Hope this help.
