Check for Currency Data Type

Hello All,
In my Dynamic Internal Table I've certain fields.
Now I want to check whether those fields are of type Currency or Quantity .
How to do this ?
Using Describe Field syntax I'm getting as TYPE C for both CURRRENCY as well as CHARACTER.
Any clues ?

Deepu.K

Hello Vikram,
Thanks for ur reply !
But when I pass my Internal table data Name to ur said FM I'm not getting any data.
So I tried with one more FM :
* Get the Layout Fields Content
call function 'LVC_VARIANT_SELECT'
    exporting
      i_dialog            = ' '
      i_user_specific     = 'A'
      it_default_fieldcat = gt_fcat
    importing
      et_fieldcat         = gt_fcat
    tables
      it_data             = gt_final
    changing
      cs_variant          = ls_variant
    exceptions
      wrong_input         = 1
      fc_not_complete     = 2
      not_found           = 3
      program_error       = 4
      data_missing        = 5
      others              = 6.
if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.
By using the above FM i got my required content.
In the FIeldcatalog I have all the DATATYPES, INTTYPEs, Decimals etc. and so by reading the values from the field catalog I coud resolve my isssue.

Checking for same data type

Im trying to do basic Math.sqrt(x*x +y*y) calculations with inputted 3 variables but want a simply error checking if-statement to find out if the variables are compatible, as in inputted 2,3,F...F will not work. Any help?

This works, and it guards against overflow when it calculates the square root of the sum of squares:
public class SquareRooter
    public static void main(String [] args)
        if (args.length > 1)
            try
                double x = Double.parseDouble(args[0]);
                double y = Double.parseDouble(args[1]);
                System.out.println("x              : " + x);
                System.out.println("y              : " + y);
                System.out.println("sqrt(x*x + y*y): " + SquareRooter.squareRoot(x, y));
            catch (NumberFormatException e)
                e.printStackTrace(System.err);
        else
            System.out.println("Usage: SquareRooter <x> <y>");
    public static double squareRoot(final double x, final double y)
        double xabs = Math.abs(x);
        double yabs = Math.abs(y);
        if (xabs > yabs)
            double ratio = yabs/xabs;
            return xabs*Math.sqrt(1.0 + ratio*ratio);
        else
            double ratio = xabs/yabs;
            return yabs*Math.sqrt(1.0 + ratio*ratio);

Handling Currency Data type in a Web Service

hello,
I have created a Java Web Service n i have tested the support for all the data types w.r.t to Java Client n C# Client.
In case of other data types, they are supported by both the clients. But in case of currency, it is not supported since there is no currency data type in C#.
For reference:
public int testInt (int aValue) throws Exception
mLogger.info("SampleAPI.testInt: Value: " + aValue);
return aValue;
I have created this method to test the support for Integer data type n it is working fine for both the clients. I want that same should be achieved for Currency Data type also.
Problem is: Since Currency does not have a constructor. i cannot set the value at the C# client end n it shows the error "Cannot create the instance of java.util.currency"
So, i reached this solution of handling the currency data type on the Service end itself by converting the currency value into decimal when the C# client sends a request for currency data type and convert it again into Currency from Decimal when the client sets the value at the Web Service end.
But it cannot be achieved since currency is not defined in any monetary sense but is using only the currency codes, so it cannot be converted.
Please tell me how to handle this thing?? Any suggestion will be appreciated.
Thanks & Regards,
Kapil

hello
i have created a transfer structure which contains the attributes of Currency class such as CurrencyCode, CurrencySymbol and FractionDigits. I can get these three attributes by:
    public CurrencyStructure getCurrency ()
        mLogger.info("SampleAPIImpl.getCurrency: ");
        Currency currency = mBackend.getCurrencyValue();
        CurrencyStructure currencyStructure = new CurrencyStructure();
        // Get the values
        currencyStructure.code = currency.getCurrencyCode();
        currencyStructure.symbol = currency.getSymbol();
        currencyStructure.fractionDigits = currency.getDefaultFractionDigits();
        return currencyStructure;
    }The C# client can get the values by calling mService.getCurrency();
The C# client can also set/change the value like this on client-end:
public void testSetCurrency ()
        CurrencyStructure currencyStructure = new CurrencyStructure();
        // Initialize the values
        currencyStructure.code = "EUR";
        currencyStructure.symbol = "e";
        currencyStructure.fractionDigits = 3;
        mService.setCurrency(currencyStructure);
}Now i want that these values should be set on the Web Service side but i m not able to set since Currency class has no setters.
I m setting the values at Service end like this, but there is no setCurrencyCode() method available in Currency class.
    public void setCurrency (CurrencyStructure aValue)
        mLogger.info("SampleAPIImpl.setCurrency: " + aValue);
        Currency currency = mBackend.getCurrencyValue();
        // Set the values
        currency.setCurrencyCode(aValue.code);
        currency.setSymbol(aValue.symbol);
        currency.setDefaultFractionDigits(aValue.fractionDigits);
    }How to achieve this??

Alter mount database failing: Intel SVR4 UNIX Error: 79: Value too large for defined data type

Hi there,
I am having a kind of weird issues with my oracle enterprise db which was perfectly working since 2009. After having had some trouble with my network switch (replaced the switch) the all network came back and all subnet devices are functioning perfect.

Can I exit from paintComponent? ...or... how can I check for invalid data?

I'm writing a calendar applet for a programming class and I've nearly completed it but I'm stuck at checking for valid data.
What seems to be happening is that paintComponent() is being called before actionPerformed.
In actionPerformed (when they click the button), it checks to make sure they entered a valid month (1 to 12). If the didn't it dispalys a message, but if they did it calls repaint().
But even if repaint() isn't called, Java still seems to call it before actionPerformed and I get exceptions.
So I tried checking inside of paintComponent() by using a simple if(...) return; but that doesn't seem to do anything... it just keeps going through with the method.
So -- Once the user presses my button I want to make sure the data is valid before repainting the screen. How can I do this?

I validate it in actionPerformed which is called by
the action listener... that is what you meant right?
The problem is that it seems paintComponent() is being
called before I can validate the data with
actionPerformed(). I need to stop paintComponent()
from always being calledMVC. (Model, View, Controller)
Initially the internal value of the data (the model) should be valid (or null with a check in the paintComponent method)
paintComponent (the view part) shows the state of the valid data.
You press the button.
actionPerformed is called (the controller).
It checks the value and, if valid, writes it to the data (model), then updates the view.
At no point will the view have to render invalid data, because the model is only updated after actionPerformed checks the value.
The pattern may be applied with different classes performing the three roles, or different methods in the same class (sometimes it's easier that way for simple cases).

Microsoft OLE DB Provider for Oracle: Data type is not supported.

I got the error:
Microsoft OLE DB Provider for Oracle: Data type is not supported.
Shortly after upgrading from Oracle 8 to Oracle 9. I was advised to download more up to date oracle drivers, but I was wondering if there was a way to tell what version of the 'OLE DB Provider for Oracle' is already at. Is there a command I can use via SQL Plus or something?

I have found Microsoft ODBC for Oracle to be more stable than the Microsoft OLEDB for Oracle driver. I have also found both Microsoft ODBC and OLEDB drivers to be more stable than the drivers from Oracle.
You could always get the latest MDAC (Microsoft Data Access Components) from Microsoft's MSDN Download site and then get the ODAC (Oracle Data Access Components) from Oracle's OTN Download site. ODAC requires MDAC. And ODAC has the latest drivers.
I suppose it would help to have the latest patches for your Oracle client software too. Maybe Oracle MetaLink would have these?
It may even help to have the latest service pack for Visual Studio 6 (Visual C++ 6 and Visual Basic 6) too.

[SOLVED] Value too large for defined data type in Geany over Samba

Some months ago Geany started to output an error whith every attempt to open a file mounted in smbfs/cifs.
The error was:
Value too large for defined data type
Now the error is solved thanks to a french user, Pierre, on Ubuntu's Launchpad:
https://bugs.launchpad.net/ubuntu/+bug/ … comments/5
The solution is to add this options to your smbfs/cifs mount options (in /etc/fstab for example):
,nounix,noserverino
It works on Arch Linux up-to-date (2009-12-02)

'Value too large for defined data type' error while running flexanlg

While trying to run flexanlg to analyze my access log file I have received the following error:
Could not open specified log file 'access': Value too large for defined data type
The command I was running is

Which should generate a html report of the web statistics
The file has approx 7 Million entries and is 2.3G in size
Ideas?

I've concatenated several files together from my web servers as I wanted a single report, several reports based on individual web servers is no use.

Java rounding for Double data type

Hi,
Is there a way to change the default precision to 2 digits after decimal point for Double data type.

java.text.DecimalFormat:
import java.text.DecimalFormat;
DecimalFormat format = new DecimalFormat("#.00");
StringBuffer formatted = format.format(Math.PI, new StringBuffer(), new FieldPosition(0));
System.out.println(formatted); // prints out 3.14Probably as applicable today as it was 3 years ago

Initialization for char data type?

I observed that as String I can declare something like this:
String str = ""; but for char data type, if I declare:
char ch = ''; the compiler will have an error: "empty character literal". So how can I fixe this problem when I want to initialize my char variables as "empty"? Anyone got an idea?

Strings (and StringBuffers/Builders) are collections* of characters - so it makes
sense to be able to refer to a String with precisely zero characters. But char is not a collection of anything - it has whatever value it has and can never
be empty.
*collections with a small 'c'.

Data change after call xml transformation for RAW data type

Hi,
Can someone explain what is workarround or any help for below problem
when call transformation is called for usr02 records, after xml string is generated is showing different data for RAW data type for example content of fields BCODE,PASSCODE etc get convert into different data
for example: content of BCODE fields before xml transformation say -7F8087472FB996E5
after xml transformation it display as f4CHRy+5luU=
why is this so happening? is this known behaviour after xml transformation or it is bug in xml transformation?
thanks in advance.
Regards,
John.

Hi,
I think this is because RAW data is BASE64 encoded when using CALL TRANSFORMATION.
Old post, but did you ever find a way to change that?
Thanks

Hi,
Make sure you have proper authorization.(sometime system does not display the error but user don't have authorization to create/update/modify table entries to be on safer side assign SAP_ALL profile to your ID if it is allowed as per your company security process).
I think issue is with InfoObject 9ALOCID is not activated properly.
You need activate InfoObject 9ALOCID as mention i below step2 but it is better you follow below steps.
1) Then force generate ODM.
2)Go to transaction code:/N/SCA/TSDM09 enter time series DFC01 and select Radio button Activate Planning object Structure.

Resources for designing data types and message types

Hi
I wanted to know if anyone can recommend me some good resources which can explain the design considerations for designing data types and message types in XI which can help promote reusability.
Thanks.
Best Regards,
Kiran

hi,
there no rare rule whe you define your data type, why i tell you this, because you define a data type since the documentation that sender sistem team gives to you. so you only have to copy this structure to PI.
now about Message Type less problems, because, you a Data type is assign to a Message Type, whats it means.
when you define a DATA type you are defining the structure of you XML, que you assing the data type to a message type this structure pass to be an xml document.
Thanks you
Rodrigo
