Assigning identifiers automatically or using the base value in rules
The question is rather simple. I want to order the instances of an entity. How these instances are ordered is unimportant. The problem is that the only information available about the instances is the age, which may be the some for multiple instances and thus makes it impossible to order. Is there anyway to assign an identifier automatically to apply this ordering, say from 0 ... the number of instances - 1 or is it possible to use the base value of an instance in rules?
Once we get into the realm of "assign randomly" we're outside the scope of "repeatable business rules" which is what OPA is trying to allow you to automate.
That said "out of the box" features to do either/both:
1) random number generation;
2) unique entity identification
have both come up before. It would be worth communicating with your Oracle product rep to make sure they know about how desirable you would find those features.
But it still sounds like you might be able to do this with rules...
Is the "discount" variable or is a voucher simply for "free tickets"? If all vouchers are always just for "whole free tickets" then they can be treated anonymously very easily. You can then look at how many tickets you have and how many you can get for free and work sequentially down the list and remove the X most expensive tickets from the total price. If the last "free ticket" is the same price as some other ticket then from a "final price for all tickets perspective" there's no difference between getting all tickets at that price at number free/total number at that price * price and getting the number free for free + full price for the rest.
So again, so long as you don't need to know which ticket and which voucher it is all possible. The major complexity is probably in constructing a "rank" but this can be done using an inferred relationship to identify a "rank" (ie the relationship identifies the set of other tickets with a greater value and then you can do an instancecount on the relationship to give you a rank).
I'm assuming you're using 10.4?
By "rank" I mean that the set (1, 2, 5, 5, 7, 9) would have the following "rank order" (1, 2, 3, 3, 5, 6) when ranking from smallest to largest.

Data type of the base attribute or the base value does not match...
...the assigned expression.
Hello all,
I always get the Error
+<ERROR+
TEXT="'DWH.CUB_REGISTRATIONS_AW.REGISTRATIONS': XOQ-02517: Der Datentyp des Basisattributs oder der Basisgröße stimmt nicht mit dem zugeordneten Ausdruck überein.
XOQ-01400: Ungültige Metadatenobjekte"/>
The English message must be something like this:
The data type of the base attribute or the base value does not match the assigned expression.
when I run my mapping. The attribute REGISTRATIONS is NUMERIC (12,2) in the Cube and I map a NUMERIC(12,2) constant in it.
I use a simple OWB-Mapping for loading, but I don't understand why it doesn't function. Other mappings where the attributes are out of a
table I put in a cube are running well.
I tried different things, but nothing fixed my problem. Any idea ?
Thanks a lot for help
MichaelTechnically this is a 'warning' from the server, not an 'error'. This means that the change you made should have been submitted, but you get an warning message on the client. AWM would suppress this warning, but evidently OWB does not. Can you switch to use AWM?
Here is the definition of the warning along with 'cause' and 'action' sections. (Unfortunately these sections are not translated into German for some reason.)
>
02517, 0, "The data type \"%(1)s\" of the base attribute or base measure is different from the mapped expression \"%(2)s\"."
// *Cause: Either the base attribute or base measure with the mapped expression was set to an inconsistent data type, or it was mapped to an expression of a different data type from its fixed data type.
// *Action: When changing a mapped expression for a base attribute or base measure, ensure that the expression has the same data type; otherwise, set the data type of the base attribute or base measure to NULL first. When a base attribute or a base measure has an existing mapped expression, do not set it to a different data type.
>
It is probably safe to ignore this warning, but if you can post the relevant XML for the cube, then will probably be able to spot the problem. I assume that REGISTRATIONS is a measure in the cube CUB_REGISTRATIONS_AW, so this is what you can look for in the XML:
(1) The definition of the base measure along with the datatype. It should be something like this
<Measure>
<BaseMeasure
SQLDataType="NUMBER(12,2)"
ETMeasureColumnName="REGISTRATIONS"
Name="REGISTRATIONS">(2) The mapping info for the measure, which should looks something like this:
<MeasureMap
Name="REGISTRATIONS"
Expression="...">
<Measure Name="REGISTRATIONS"/>
</MeasureMap>I don't know if you can get the XML directly from OWB. If not, then DBMS_CUBE.EXPORT_XML should work (assuming you are in 11.2). You could also attach AWM and save the cube to an XML template. -
Getter/setter methods -- how do I use the return values
I'm just learning Java, and I haven't been to this site since the end of July, I think. I have a question regarding getter and setter methods. I switched to the book Head First Java after a poster here recommended it. I'm only about a hundred pages into the book, so the code I'm submitting here reflects that. It's the beginnings of a program I'd eventually like to complete that will take the entered information of my CD's and alphabetize them according to whatever criteria I (or any user for that matter) choose. I realize that this is just the very beginning, and I don't expect to have the complete program completed any time soon -- it's my long term goal, but I thought I could take what I'm learning in the book and put it to practical use as I go along (or at lest try to).
Yes I could have this already done it Excel, but where's the fun and challenge in that? :) Here's the code:
// This program allows the user to enter CD information - Artist name, album title, and year of release -- and then organizes it according the the user's choice according to the user's criteria -- either by artist name, then title, then year of release, or by any other order according to the user's choice.
//First, the class CDList is created, along with the necessary variables.
class CDList{
private String artistName;//only one string for the artist name -- including spaces.
private String albumTitle;//only one string the title name -- including spaces.
private int yearOfRelease;
private String recordLabel;
public void setArtistName(String artist){
artistName = artist;
public void setAlbumTitle(String album){
albumTitle = album;
public void setYearOfRelease(int yor){
yearOfRelease = yor;

recordLabel = label;

I'm confused about getter and setter methods -- I'd like someone to explain to me what they are used for exactly and the difference between the two.

The program compiles and runs fine, but I can't seem to figure out how I'm not using the returned values from the getter methods. Please help and if you can explain in 'beginners terms,' with any code examples you think are appropriate. It will be greatly appreciated.
By the way, I'm not a professional programmer -- I'm learning Java because of the intellectual exercise and the fun of it. So please keep that in mind as well.

But this is something every new programmer goes through, and I will not spoil the fun. You see, in 3 to 6 months when you have learned much more Java, assuming you stick with it, you will look back at this and be like "what the hell was I thinking" and then realize just haw far you have come. So enjoy that moment and don't spoil it now by asking for what could have been better/ more efficient. If it works it works, just be happy it works.

So please keep that in mind as well.First, if you posted this somewhere else you should link to that post, it is good you at least said you did, but doubleposting is considered very rude because what inevitably happens in many cases is the responses are weighed against each other. So you are basically setting anyone up who responds to the post for a trap that could make them look bad when you double post.
You are setting you getters and setters up right as far as I can tell. Which tells me that I think you grasp that a getter lets another class get the variables data, and a setter lets another class set the data. One thing, be sure to use the full variable name so you should have setRecordLabel() and getRecodLabel() as opposed to setLabel() and getLabel(). Think about what happens if you go back and add a label field to the CDList class, bad things the way you have it currently. Sometimes shortcuts are not your friend.
And yes, you are using the getters all wrong since you are not saving off what they return, frankly I am suprised it compiles. It works because you don't really need to use the getters where you have them since the CDList Record (should be lowercase R by the way) object already knows the data and uses it in the printout() method. Basically what you are doing in lines like:
Record[x].getArtistName();is asking for the ArtistName in Record[x] and then getting the name and just dropping it on the floor. You need to store it in something if you want to keep it, like:
String artistName = Record[x].getArtistName();See how that works?
Hope this helped, keep up the good learning and good luck.

How do I use the Index Values property node with a multidimensional array.
I am using a 2D array to store operator inputs on my front panel. I only want to display one element to the operator at a time. I am trying to use the Index Values property node to change the displayed element. However, I can only get the Rows index to work. How do I direct the Columns index as well? The help says to use one per dimension. I need clarification on what this is talking about. I've tried adding a second element to the property node, 2 seperate property nodes, and diferent wiring techniques. (series, parallel)
If you only wire up one of the inputs (col or row) what you get out is a 1D array of either the column or row. If you wire controls to both, then you will get one element out of the array. Getting a single element in a 2D array requires you to specify both a row and column.

AvijitAvijit,
I got your requirement. I really dont know the scenario your working on but its possible to do it. There is no direct way to do so, but complexity is in getting to know the Keys dynamically from interface.
Here you go..
try
Class msgClass = IMessageTestWDApps.class;
//Replace IMessageTestWDApps with IMessage<Your WD Component name>
Field keys[] = msgClass.getFields();
IWDTextAccessor textAccessor = wdComponentAPI.getTextAccessor();
if(keys != null)
String key = "";
for(int index=0;index<keys.length;index++)
key = keys[index].getName();
wdComponentAPI.getMessageManager().reportSuccess("Key= "+key);
if(textAccessor.getText(key).equals("My message text"))
//your logic.
catch(Exception cnfe)
wdComponentAPI.getMessageManager().reportException("Exe "+cnfe.getMessage(),false);

Hello,
I am very new to JavaScript. I would like to create a checkbox with a numerical value variable activated if the box is checked. Unfortunately, I cannot use the 'Export Value' because I already need to use it for something else.
Any help is really appreciated.
Thanks,
RobynBrace yourself, here's your solution.
First of all, the export value of you checkboxes should definitly be the number of hours for the class since you will just add them up further.
Second, we will use the userName property for our second export value (its the field right under Name and its labeled "tooltip"). You will name the class there.
Finally, you need to name each checkbox with a number at the end starting with 1 all the way to 190. This will be used in loops. ("whatever.1", "whatever.2,....."whatever.190")
In the calculate event of "total hours":
var sum = 0; //declaring a variable that will be used in the loop
for (var i = 1; i <= 190; i++){ //this loop will scan through all your checkboxes
if (this.getField("whatever."+i).isBoxChecked(0) == true){ //if box is checked....
sum += Number(this.getField("whatever."+i).value); //.....add its value to the sum
event.value = sum; //display the total
Now for the course name field, we will use the same pattern in the calculate event
var courseList = new Array(); //declaring an empty array that will contain the courses
for (var i = 1; i <= 190; i++){ //this loop will scan through all your checkboxes
if (this.getField("whatever."+i).isBoxChecked(0) == true){ //if box is checked....
courseList.push(this.getField("whatever."+i).userName); //.....add its userName (tooltip) to the array
event.value = "You are attending these courses: "+courseList.join(", ")+"."; //display the array by turning it into a string and joining its items with ", "
You can try it out with just a few checkboxes at first. Don't forget that the loop mustn't go further than the existing field or you will get an error and the script will stop. Make sure no error show in the console (ctrl+J). -
How do I convert the ASCII character % ,which is 25h, to a hex number 25h. I've tried using the scan value VI but I get a zero in the value field.
You can use String to Byte Array for this.

Result Row of Formula is not using the displayed values
Good Day,
I got a query with following layout
Child Ship Parent Ship Rate
Child Parent ST ST %
Material A F6WH F6WH 55 22 250,00
F7D1 F7D1 55 33 166,67
F8LG F8LG 55 11 500,00
Result 55 66 250,00
The child ship key figure has a setting calculate result as average to display the total shipment of the child. Rate is defined as formula Child Ship %A Parent Ship.
In the result row as Rate I require 83% (55 divided by 66).
It seems that the Rate formular still uses the SUM of child ship 555555 (165 diveded by 66).
Anyone an idea how to get the "wanted result" of 83% ?
Thanks for all replies in advances (points will be assigned).
AxelHi,
As far as i understand the issue is with the child ship keyfigure in that you have selected calcualte result as average which is only for display purpose that result cant be used for futher calculations.
If you want to calculate the average make use of exception aggregation.
Make a new formula and put you keyfigure for which you need to calculate avg. then hit Aggregation tab---Exception aggregation as average and refernce characterstic choose on which you are getting unique set of values.
Then continue with your other steps.
Hope it helps.

How can I use the output value from SIMPLE PID to write something to the serial port?
I am working on my Senior Design Project that requires the use of incoming compressed air, propotional valves, continuous servo motors, and a serial servo motor microcontroller. I have figured out how to send byte sequences to the microcontroller through LabVIEW using the VISA serial write function. The motors are attached to the valves to control the flow rate. I have created my own simple feedback system using a bunch of case structures but I realized that I am basically trying to recreate the wheel (I basically was writing my own PID VI). I have an older version of LabVIEW (7.0 Express) and theres no way to upgrade or buy the PID toolkit, so I am stuck using the Simple PID VI. Also, the only way the motor works is sending an array of bytes to tell it to turn on/off, direction, and speed. Is there any way I can use the Simple PID VI in conjunction with the VISA SERIAL write function, or is there any other way I can communicate with the serial port using this pid vi? Any information would be appreciated.
Hi gpatel,
you know how to communicate to serial port, but you don't know how to send a value from SimplePID to serial port???
You know how to communicate, but then you don't know how to communicate???
You should explain this in more detail...
Edit:
From you first post you know what values your motor driver is expecting. You know which values the PID.vi is providing. Now all you need is a formula to reshape the values from PID to the motor. It's up to you to make such a formula. Unless you provide any details we cannot give more precise answers...

How to use the variable value "ALL"
Hello all,
I'm trying to use the value "all" for a selection variable in a Web Interface so that to have no restrictions for that specific variable and that all the rows are shown on the interface.
Unfortunately it does not seem to be working because when I select the value "all" the system seems to go back to the latest rows saved under a specific value for that variable and does not show all the rows saved under any variable's value.
Anyone knows how to make this work? One option is to remove the variable from the web interface altogether, but that's my last option.
Thanks in advance.
Best regards,
FrancescoHi Francesco,
why is leaving out the variable your last option? If you want to select "all" then you don´t need a variable.

Corelating messages using the Dynamic Values
Hi all,
I want to collect message using BPM.I have sucessfully executed the same using corelation from one of the fields.The ID field was used for corelation
I was able to sucessfully execute the senario the messages with same ID were going to same process ID and getting collected as well
Now i wanted to have some dynamicconfiguration parameters for eg i thought i can use the filename.That is collate the messages using the filename.
I changed the corleation and tried but for each messages even with the same file name its creating a different process ID and thus my messages are not collected at all.
To tel you more about the senario i created its a file to file with BPM collecting the messages. i send the first file and then the second file also with the same file name.
I have configured the AdapterSpecific Attributes and able to view the filenames in the XML Messages header
Can anyone put some light as too why there are different Process IDs being created.I heard in some of the forums that its an error in some of the SPs
I am on XI 7.0 SP11 and think it should not be a problem.
Thanks in Advance

Adityathnks for ure replies
But all of the above steps are checked
It seems that i have given the right co-relation as well but still dnt knw y i'm not able to collect the messages
The loop is defined to complete after a fixed count and the container variable increments by 1 after each loop
The senario works perfectly if i use any field corelation to collect the messages but fails when i use a dynamic value like filename. And yes i have double checked the filename they are same
