Class conversion

Hello, I'm stuck into a very simple thing.
I've a class A, and a subclass B. Then I create an object that way:
A myObject = new B();
Then, what do I get from B?
I mean, do I get B methods? B attributes? Not B methods, but overwritten methods such as toString?
And what do I get from A?
I'm very confused.
Thank you.

I mean, do I get B methods? B attributes? Yes, but to access them, you'll have to cast:
B myBObject = (B) myObject;If this is the case, it would be better just to write:
B myBObject = new B();and not bother with the variable of type A.
Not B methods, but overwritten methods such as toString?If B overrides methods, you get those overridden methods
And what do I get from A?Anything inherited from A.

Inventory UOM intra-class conversions

Hi all. I need to know if I can view the on hand quantity in diferent UOM's (primary-secondary and all conversions configured by item)
thanks a lot
11.5.10
Edited by: omator on 11-feb-2010 9:02

UOM Conversions are standards. One does not define tolerances when defining standards.
For example 1 Dozen = 12 Nos, it does not make sense to define a conversion like 1 Dozen = 12 nos +/- 1 nos.
However you may define an item specific UOM Conversion, (which overrides the Standard UOM Conversion) that may define the conversion as, say 1 Dozen = 13 Nos for Item01.
But to take care of the tolerances as you put it,
assuming Dozen has been defined as the Primary UOM for an Item, you may ingeniously chose to receive the item in Nos (if Nos and Dozen belong to the same class).
Eg: if you want to use 1 Dozen = 11 Nos, receive the item in Nos instead of Dozen.
However, if you have a Secondary UOM defined for the Item, you may define a tolerance for the COnversion between Primary & Secondary UOM using the Deviation +ve & -ve fields in the Item Master.
Hope this clarifies, Revert if you have a specific scenario.

String to Library Class conversion

Hi guys, i'm having trouble coming up with a good way to
convert a string to class reference from the library without using
a lookup table in Actionscript 3.0
so say i'd loaded in some data from xml and i need to
generate a new instance of a "Box" from a linked extended Sprite in
the library.
without the string i'd just go var myBox = new Box();
but obviously i can't go var myBox = new "Box"() so i'm kind
of stuck without using a lookup table to convert the string passed
to the appropriate Class linkage.
Any help would be much appreciated,

Class conversion error

Hi Friends,
I'm new to Java card technology. I set the environment variable and the remaining properly. I'm using Windows XP platform And using Java 1.4 and Java card 2.1.2. When I run "build_samples.bat" after compiling the Java file successfully, when It tries to convert the class file into JCA or CAP it says an error "unsupported class file format of version 46.0". I don't what it means and how to rectify that?
Thank you for helping me.

Use JDK 1.3 as stated in the Java Card Kit or use something like the options -target 1.1 -source 1.3 with the compiler.

XML to Java Class Conversion.

Hi all,
I need to convert a XML document to Java class.
Then create numerous objects of this class.
Convert the multiple objects single XML file
Im able to convert objects to XML..
But I need a way to convert XML document to Java class..
Any ways to do the same??
Thanks.

1.Define an XML Schema for the XML document and compile the schema to Java classes.
2.Unmarshall the XML document with the Java classes.

BOR to Classes conversion

As BOR is being phased out is anyone aware of any tools around to convert some useful BOR's to Classes.
I think in general in workflow one should try and use classes and objects wherever possible rather than the older BOR method.
A lot of supplied SAP workflows however are still based on BOR so this area could become a bit of a minefield especially in CRM and similar type of processing.
As new projects come on stream I'd be interested to know how people are going to handle this topic.
Cheers
jimbo

This doesn't address the topic. All of the above features can be done via OO classes --you can of course have multi-line objects and "virtual attributes" in a class.
A problem with BOR is that you can't easily call these from "Classical ABAP" programming so say you want all the partners of a sales order you normally have to code the functionality yourself using the relevant tables rather than try and get the attributes of a relevant BOR in your program.
However once you've defined say a SALES ORDER class then any ABAP can access the public attributes and methods of this class .
With the BOR it's OK via workflow but a "Normal ABAP" program has to do some fancy coding using the "SWO" or workflow macros and functions to access the attributes of the BOR.
Since these are internal SAP macros and could be deprecated at any time it's really not surprising that outside the Workflow environment BOR's are rarely used in standard ABAP programming.
BOR was a "stepping stone" used by SAP to implement some of the features of OO abap before OO abap became reasonably powerful itself.
Inheritance, encapsulation etc etc are all standard in OO -- not restricted to BOR's.
The trick is to ensure your new class has the functionality of the old BOR and use that wherever possible on new projects.
Like BOR if you extend methods and attributes you don't need to change any existing programs using the relevant classes.
I'm sure the next major upgrade of sap will implement many more business classes -- the old BOR could be retained by simply calling a Class of the same name having the same attributes and objects for legacy code and workflows.
For example here's some ABAP code to call a method which returns the Long Text of a Service notification BOR ZBUS2080 (delagated BOR BUS2080)
You can see it's quite a "Dogs Dinner".
Much more simply and easily done of course if you had a similar CLASS available. (call me=>) etc.
Program ZZREADBOR.
Sample program to execute a method of a business object
or return an attribute of a Business object
can be used in or outside of Workflows etc.
Use this as a model
Note on some definitions used in WF / Object
programming.
A container is a special type of "generalized"
parameter used in workflows for passing data
between steps.
You can use these in "Normal" programming
It's just a generalized structure for holding
data.
An Attribute in this context means a field e.g Short
text. The attribute can be a table (multi-lined)
as well.
The attribut is defined in the attribute list
of the business object
Use transaction SWO1 to see the list.
Operations on containers are done via
standard SAP Workflow macros
swc_function such as swc_create_object.
You must supply a key to instantiate the object
and the object name
(Instantiation means just supplying
the objects key --such as
in the case of a sales order the key would be
the sales order number).
Parameters
Enter Business object name e.g ZBUS2080
key of business object e.g sales doc nr etc.
Attribute you want if getting an attribute property
Method name if executing a method.
For retrieving attributes the data is returned
in field return.
For Methods a little extra work is required as follows:
For Methods you may need extra container
parameters such as
tables (swc_get_tabe container containerElement Itab)
To see what elements are needed have a look at the
Method code (transaction SWO1=== select
the business object(display) chose the method and then
select the program button
container parameters will be identified the code
by swc_set_element / table for export parameteres
swc_get_element / table for import parameters.
ensure you set your container(s) to persistent
this ensures the container exists throughout
the whole run and is available to sub programs
function modules, methods etc.
if you don't do this then the container only exists
in the program and disappears when you enter a function
module method etc etc.

for swo invoke -- access type 'G' ====> get attribute

this function is executed internally.
in the perform (p_method) statement the sap kernel knows
that the program is actually a business object type of program
not a "Normal" abap so the perform gets handled a little
differently than the usual perform statement.
You cannot execute the BOR program via SE38.

Conversion or transformation ?

Hi,
In our domain model, we have many enumerated types, or in other words, classes with a finite number of read-only instances . A good example would be a class named Country. This class has some attributes and a unique identifier.
Since all this stuff is read-only, does such a class need to have its own database table ? A class having a one-to-one relation with a Country could store the country identifier and Toplink use it to resolve to the single in-memory instance, avoiding an access to Country table.
I'm not sure if this is good design. And if it is, I don't know how to configure Toplink to do this. Conversion, transformation, variable one-to-one mapping ???
Any comments would be appreciated
Jean-Christian Gagné

Jean-Christian,
A little confused by your question. Do you want to have the table at all or are you just trying to avoid the read on the table each time.
If you are trying to avoid the read then I would suggest keeping the 1:1 mapping and pre-loading all Country instances at system startup. This is common for reference data and will avoid any additional queries on the table.
If you wish to eliminate the Country table then you have a couple of options to handle the country-code to Country instance conversion.
1. Use an ObjectTypeMapping and populate it at startup time with the static set of Country instances
2. Use a TypeConversionMapping and specify the database type as String/int (whatever the code is). The object type will automatically be found in the mapped class. Then extend the ConversionManager to also support you Country class conversion to and from the code type. (see http://otn.oracle.com/products/ias/toplink/technical/tips/customconversion/index.html).

Batch Classification by class type 022

Hi all,
We are using batch management at material level and present class type 023. We are looking at changing the class type to 022 as we need some information to be retained at plant level.
While creating class for class type 022 the system gives an error " Internal class type 022 cannot be used in class maintenance
Message no. CL089"
Can somebody let me know the reason and solution for this error? Is it due to the fact that we have set the batch at material level?
Also, it would b great if someone can share his/her experience in changing batch clases, even class conversion.
Best Regards,
VS

Hi VS,
I think that you should change the customizing first. Class types 022 and 023 can not be created simultaneously. It is either 022 or 023.
Be careful : I did it long time ago but there is one way you can do (023 to 022 or 022 to 023 I don't remember) but you cannot reverse it.
Rgds,
Philippe

Maintaining variable conversion weight by LOT-wise

Hi,
I could not try this thing as I do not have any 10g set up at the moment, but hope this works. I am assuming that you are using Oracle DB at the moment.
1. Create an initialization block that initializes the variable XX_PROD_LINE.
2. Create another variable that can store the length of this variable.
3. Create another initialization block that fires a query like
select length(:XX_PROD_LINE) from dual
4. Set this initialization block to execute only after the initialization block in step1 (You can use initialization block precedence for this). This step ensures that the length of the variable is calculated only after it has been initialized.
5. Now you can use this variable in your reports.
Hope this helps.
Thank you,
Dhar

VISA is the generic communication interface.
Hyperterminal has serial comm drivers as well. It just so happens that Hyperterminal is using the serial comm drivers that are built into Windows. That's why you don't notice them.
If you installed LabVIEW, then you should have installed the drivers that come with it. It is on a separate DVD. Obviously you haven't.

Customer API is not available on 12.0.6/12.1.1. Thanks for pointing out. I will correct it. If you require customer API, please log an enhancement request through SR.

Output problem urgent!!

Okay so heres the problem i have a piece of code to convert a decimal value that a user enters into a binary value. My algorithm works its just when the binary value is displayed only the last element of the binary value to be outputed is displayed. But i want all the values of the binary number to be displayed. I dont know what to do plz help.
the code i am using is:

          {                                             //Or exactly equal to 1

Each element in the array b contains one digit of the binary representation. You need to convert each digit into a character and then concatenate all the characters into a String before displaying anything.

API/package/procedure/function for updating physical attributes in Org/Mast

I need some kind of procedure or function for updating the weight, volume, and dimensions in the organization and master items forms. We have almost 350,000 items and I want to update them in batch. Is there an API of some kind for this? I would do a simple update but I want to make sure there's no additional logic necessary (other tables that are updated during the process of updating those fields, etc).
Thanks!

here is for API's you need to check...
You can use Decimal & UOM Quantity API
These APIs are used to handle item decimal quantities:
Convert from one UOM to another
Validate quantities at input time
Validate quantities at display/output time
Quantity Comparison
Get UOM information
For your convenience, I am giving you the API as below:

+===========================================================================*/
/*-----------------------------------------------------------------------+
|This package contains procedures relevent to item decimal quantity |
|processing. This package contains routines to: |
|(1)validate item quantities based on UOM and decimal precision rules |
|(2)validate whether the UOM controls and decimal precision rules |
| themselves are correct based on functionality planned. For reviewing|
| UOM and decimal quantity functional design details, please visit the|
| following URL: |
| "http//apps-us.oracle.com/inv/development/designs_120/ |
| decimal_precision/decimal_precision.html" |
|But here are a few basics to give background context: |
| |
| "Item Quantity" -- The item's quantity is described by the item |
| identifier, the unit of measure (e.g. grams, kilos, etc), and a |
| number value to indicate the amount in that unit of measure. |
| |
| "Unit of Measure" -- Units of measure belong to unit of measure |
| classes(e.g. weight, volume, length, etc). Each unit of measure class|
| has actual units of measure that belong to that class (e.g. the |
| weight class may have units of measures like, "grams", "kilos", etc).|
| |
| "UOM Conversion" --Users can set up conversion rates between UOMs in |
| them same UOM class, by defining conversions to the base UOM. These |
| are standard conversions. Item-level intra-class conversions may also|
| be defined. When doing intra-class conversions, item-level |
| intra-class conversions are used first if defined, and then standard |
| conversions are used. |
| Users can define inter-class conversions. Inter-class Conversions may|
| also be defined at the lot/sublot levels. For inter-class conversions|
| sublot, lot, and then item inter-class conversions will be used in |
| in order. If lot-lvel conversion is not defined, then item-level |
| conversion is used. A strict hierarchy is imposed. |
| |
| "TU" -- Trasactable Unit.A UOM may have a TU. This implies |
| that when transacting in this UOM, any item's quantities will be |
| forced to be integer multiples of this TU quantity. The TU may also |
| be declared at the item level. The TU quantity at the item level may |
| be different from the UOM level TU, and if defined, item level TU |
| takes precedance. |
| |
| "Decimal Precision"--Users have a choice of setting decimal precision|
| at the base UOM for each UOM class. All other UOMs in that class get |
| get their decimal precisions derived from the base UOM decimal |
| precision, the converison rate, and TUs, if they are |
| being used. |
| |
| |
| "Conversion Rate Tolerance" -- This is a tolerance that may be set |
| when conversion rate cannot be not strictly fixed. Example: |
| 1 Chicken = 2 pounds (plus or minus 0.7 pounds). This 0.7 pounds is |
| the conversion rate tolerance. Conversion rate tolerance is only |
| definable at inter-class UOM conversions, at item or lot/sublot level|
| |
| History |
| 04/08/99 Mansoor Jafri Created Package Spec |
| 04/26/99 Mansoor Jafri Updated with TU at 3 levels as |
| opposed to MTU at 2 and atomic at|
| UOM class level. |
| 04/29/99 Mansoor Jafri Updated document with lot/sublot |
| conversions. Also, removed |
| "atomic" as a separate control, |
| since this can |
| implemented as a TU at base UOM |
| level with an integer quantity. |
| 05/03/99 Mansoor Jafri Updated the package with sublot |
| level control. Also, changed name|
| of DTU to TU, so that it fits |
| better in the "process" market. |
| Also, conformed to BOI API stds. |

Failed to retrieve data from the database. [Database Vendor Code: 116]

My report is using Java Bean class as datasource and the Java Bean class calls a report-specific Java program to return a result set.
Report fails to generate and the error message is
Failed to retrieve data from the database. Details: [Database Vendor Code: 116 ]
Can anyone tell me what error code 116 means?
Thanks.

The problem is solved internally. Our team implemented a result set data structure that incorrectly converts a Double into a String before passing it to Crystal Report for rendering. Data Vendor Code I met yesterday was the outcome of illegal class conversion.
I have a side question; our development team would like to use log4j to log method calls invoked during rendering. Our problem could be solved earlier if we knew getString() was invoked instead of getDouble() during rendering. We thought of specifying the full path of log4j jar file in CRConfig.xml but we don't know how to configure CR to write logging information into a specific file location.
Please help.
Thanks
