What is the programming (ABAP) difference between Unicode and non Unicode?

What is the programming(ABAP) difference between Unicode and non Unicode?
Edited by: NIV on Apr 12, 2010 1:29 PM

Hi
The difference between programming in Unicode or not Unicode is that you should consider some adjustments to make on the Program "Z" to comply with the judgments Unicode Standard.
In the past, developments in SAP using multiple systems to encode the characters of different alphabets. For example: ASCII, EBCDI, or double-byte code pages.
These coding systems mostly use 1 byte per character, which can encode up to 256 characters. However, other alphabets such as Japanese or Chinese use a larger number of characters in their alphabets. That's why the system using double-byte code page, which uses 2 bytes per character.
In order to unify the different alphabets, it was decided to implement a single coding system that uses 2 bytes per character regardless of what language is concerned. That system is called Unicode.
Unicode is also the official way to implement ISO/IEC 10646 and is supported in many operating systems and all modern browsers.
The way of verifying whether a program was adjusted or not, is through the execution of the UCCHECK transaction. Additionally, you can check by controlling syntax (making sure that this asset verification check Unicode).
The main decisions to adjust / replace are (examples):
ASSIGN H-SY-INDEX TEXT TO ASSIGN <F1> by
H-SY-INDEX TEXT (*) TO <F1>.
DATA INIT (50) VALUE '/'. by
DATA INIT (1) VALUE '/'.
DESCRIBE FIELD text LENGTH lengh2 by

What is the exact technical difference between "Lightning to USB Camera Adapter" and "Lightning to USB Cable"

Mainly I am interested in attaching the iPhone to a receiver (or car etc.) to play music.
Both the "Lightning to USB Cable" and the "Lightning to USB Camera Adapter" seem to do the trick. So what is the exact technical difference between the two items?
When connected to a receiver, is the iPhone the USB Master in both cases? Is the USB "Audio Device Class" standard used to transmit audio?

Thanks for all the answers! I think I should specify the use case much more clearly. Sorry for not having done this earlier.
Use Case 1:
When I connect the iPhone to the receiver I can use the Lightning to USB, because the receiver has a female type A, just like e.g. a PC or like the charger. So I would agree that the Receiver must be the USB host, and the iPhone the USB device. This works just fine in my case, with iPhone and iPad.
In this case, the audio goes from the device to the host, or "Audio-in".
Use Case 2:
A friend of mine has a small device that converts USB to Toslink. This thing has a female Mini USB Type A, which is typically used at the receiving side of a USB connection. This device can be connected e.g. to a Mac, and then the Mac can output audio via this device to receiver which accepts optical Toslink signals.
In this case, the audio goes from the host to the device, or "Audio-out".
It is this use case 2 that I am unsure about:
a) Can the Lightning to USB cable be used in this case (assuming that I find the necessary non-standard adapters to actually connect the USB ports)? This would mean that the iPhone can act as a USB host with the Lightning to USB cable.
b) I know that the Lightning to USB Camera Adapter does convert the iPad into an USB host, otherwise it could not read data from a camera. So could this adapter also be used to produce "Audio out" to a USB device that supports receiving music?
If yes, would this also work with an iPhone (as pointed out in another answer, the iPhone does nor support reading pictures from a camera)?

See the following threads
non-cumulatives KF in reporting
Re: use of non cumulative keyfigure
Re: When do we use Non-Cumulative values?
Key figures:
1. Cumulative Vaules
2. Non Cumulative Values
Cumulative Values:
Cumulative Values are Keyfigures for which Keyfigure Values are must posted in every time unit that reported on (= time period specific Values).
Example:
Revenue
Non Cumulative Values:
Non Cumulative Values are Keyfigures for which KeyFigures are only evaluated for selected time Periods.
Cumulative Keyfigures With Exception Aggregation:
It's a 'normal' KF (with summation, min or max as aggregation behaviour), but you set some exception in this behaviour...for example, you can say that a KF, normally aggregated by 'summation', have to show the max value (or the average, or '0' or something else), that is the 'exception aggregation' when you use it in combination with 0DOC_DATE (or other char), that is the 'exception aggregation char reference'...in this case OLAP processor give to you the possibility to see your KF with different behaviour depending from you use 0DOC_DATE (in our example, MAX) or something else (SUMMATION).
Non Cumulative keyfigure with Associated Single Delta:
If you have a stock KF that is fed from only one (other) movement KF that can assume positive and negative sign.
KF1 (initial) STOCK (non-***.) = 100
KF2 flow = -30
KF2 flow = 70
KF1 (final) STOCK (non-***.) = 140
Non-cumulative key figure with associated in and outflow:
This is the case of 2LIS_03_BF KF stocks fields.
Here, we have the same situation in point 2, but you will have not only ONE flow KF, but TWO, one dedicated to in and another one dedicated to out !
You have to use this scenario if you have no KF that have positive and negative sign, but two KFs each one representing positive (in) and negative (out) logical sign!
KF1 (initial) STOCK (non-***.) = 100
KF2 (out))flow = 30
KF3 (in)flow = 70
KF1 (final) STOCK (non-***.) = 140

Differnce between unicode and non unicode

Hi every body i want to differnce between unicode and non unicode and for what purposes this ulities are used explain me little brief what is t code for that , how to checj version, how to convert uni to non uni ?
Advance Thanks
Vishnuprasad.G

Hello Vishnu,
before Release 6.10, SAP software only used codes where every character is displayed by one byte, therefore character sets like these are also called single-byte codepages. However, every one of these character sets is only suitable for a limited number of languages.
Problems arise if you try to work with texts written in different incompatible character sets in one central system. If, for example, a system only has a West European character set, other characters cannot be correctly processed.
As of 6.10, to resolve these issues, SAP has introduced Unicode. Each character is generally mapped using 2 bytes and this offers a maximum of 65 536 bit combinations.
Thus, a Unicode-compatible ABAP program is one where all Unicode checks are in effect. Such programs return the same results in UC systems as in non-UC systems. To perform the relevant syntax checks, you must activate the "UC checks" flag in the screens of the program and class attributes.
With TC: /nUCCHECH you can check a program set for a syntax errors in UC environment.
Bye,
Peter

HI Subu ,
there is some information gap , what is your source ? are there any transformation in between ?
If its SQL server source and destination and the datatype is as you have mentioned I dont think you should be getting such errors ... to be sure check advance properties of your source and check metada of your source columns
just check simple oledb source as
SELECT TOP 1 ItemCode = cast('111' as nvarchar(50)),DivisionCode = cast('222' AS nvarchar(50)), Salesplan = cast(3.3 As float) FROM sys.sysobjects
and destination as you mentioned ... it should work ...
somewher in your package the source columns metadata is not right .. and you need to convert it or fix the source.
Hope that helps

SSIS Package : While Extracting Sharepoint Lookup column, getting error 'Cannnot convert between unicode and non-unicode string data types'

Hello,
I am working on one project and there is need to extract Sharepoint list data and import them to SQL Server table. I have few lookup columns in the list.
Steps in my Data Flow :
Sharepoint List Source
Derived Column
its formula : SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1))
Data Conversion
OLE DB Destination
But I am getting the error of not converting between unicode and non-unicode string data types.
I am not sure what I am missing here.
In Data Conversion, what should be the Data Type for the Look up column?
Please suggest here.
Thank you,
Mittal.

You have a data conversion transformation. Now, in the destination are you assigning the results of the derived column transformation or the data conversion transformation. To avoid this error you need use the data conversion output.
You can eliminate the need for the data conversion with the following in the derived column (creating a new column):
(DT_STR,100,1252)(SUBSTRING([BusinessUnit],FINDSTRING([BusinessUnit],"#",1)+1,LEN([BusinessUnit])-FINDSTRING([BusinessUnit],"#",1)))
The 100 is the length and 1252 is the code page (I almost always use 1252) for interpreting the string.

Column "A" cannot convert between unicode and non-unicode string data types

I am following the SSIS overview video-
https://secure.cbtnuggets.com/it-training-videos/series/microsoft-sql-server-2008-business-development/6143?autostart=true
I have a flat file that i want to import the contents onto a SQL database.
I created a Dataflow task, source file and oledb destination.
I am getting the folliwung error -
"column "A" cannot convert between unicode and non-unicode string data types"
in the origin file the data type is coming as string[DT_STR] and in the destination object it is coming as "Unicode string [DT_WSTR]"
I used a data conversion object in between, dosent works very well
Please help what to do

I see this often.
Right Click on FlatFileSource --> Show Advanced Editor --> 'Input and Output Properties' tab --> Expand 'Flat File Source Output' --> Expand 'Output Columns' --> Select your field and set the datatype to DT_WSTR.
Let me know if you still have issues.
Thank You,

Difference between deamons and non deamons

Pls someone tell me wat is the difference between deamons and non demons and i know that deamons will run in the background..and pls tell me why they r used...

Actually it's "daemon" (mythologically speaking a little more benign than demons).
A Java program terminates when every non-daemon thread finsihes. Setting a thread to daemon mode simply says that it's ignored for this purpose. It's usually used with background activities that can be abandoned at the end of the program without any need to clean up.
(More widely, in unix, a daemon program is one that runs in the background all the time, from when you boot up the machine to when you close it down.)

Difference between cumulative and non-cumulative key figures

Hi,
What is the difference between cumulative and non-cumulative key figures and under what conditions they are used. What is snapshort and where it is used.

Hi.............
Basically the key figures are of two types cumulative and non cumulative.
Cumulative are the normal one which you use always and they always bring the new values of the key figures in the delta that is if suppose A has value 10 and after change the new value is 20 then you will use cumulative key figures there, and your delta( new value) will bring 20.
but suppose your key figures field only the change in the prior value that is in this case the delta in the key figure value will bring 10 (20-10- change of 10 )as new value in the key figure A then you will have to model it through the non cumulaitve key figures.
Now
1) Cumulative is for the first case that is if the key figure alwyas brings the new values of the key figure and not the change sin the key fiures value.
2)NCum. value with NCUM value change:
In this case ther is only one field which brings the changes for a particualr key figure and you ahve to define that key figure as non cumulative.
Ex: In case of stock only one filed brings both ingoing value and outgoing value so 10 ,-4,100,-34.....
In this case you will this option and use the key figure here in the space provided.
3) In this case you haev two separate key figures one for the inflow of stocks and one for the outflow of the stocks.
you use one key figure for the inflow and one key figure for the outflow.
The main key figure autiomatically takes care of the logic and gives the correct output upon the summation
net value of stocks( inflow- outflow).
Also do remember in this case the key figure for inflow and out flow are the basic key figures that is cumulative key figures.
A non-cumulative is a non-aggregating key figure on the level of one or more objects that is always displayed in relation to time. Examples of non-cumulatives include headcount, account balance and material inventory. here the aggregation of key figure is based on the another info object
There are two different ways to define non-cumulative key figures:
Non-cumulative key figure with non-cumulative changes:
Before you can define the non-cumulative key figure, an additional cumulative key figure containing the non-cumulative change must exist as an InfoObject.
Non-cumulative key figure with inflows and outflows
There has to be two additional cumulative key figures as InfoObjects for non-cumulative key figures - one for inflows and one for outflows. The cumulative key figures have to have the same technical properties as the non-cumulative key figure, and the aggregation and exception aggregation have to be SUM.
Features of non-cummulative key figures
A non-aggregating key Figure.
Records are not summarized for Reporting
Exception Aggregation is being applied on these key figures on the level of one or more info objects usually with time .
Examples: Head Count, Account balance, Material stock
consider simple senario
Date Net Stock Quantity Sales Revenue
01.02.2005 40 1000
02.02.2005 50 2000
03.02.2005 25 3000
this is the query output if stock quantity has treated as cummulative and non-cummulative key figures
if stock quantity taken as a cummulative key figure
Date NET STOCK QUANTITY SALES REVENUE
01.02.2005 30 1000
02.02.2005 50 2000
03.02.2005 20 3000
RESULT 100 6000
in the above result the key figure has aggregated to the total value that wont give sense to the net stock quantity
if stock quantity taken as non-cummulative key figure
Date Net Stock Quantity (LAST) Sales Revenue
01.02.2005 30 1000
02.02.2005 50 2000
03.02.2005 20 3000
RESULT 20 6000
Hope this helps you..............

Difference between stock and non stock material

what is the difference between stock and non stock material. example of stock and non stock material?

Hello,
Stock Material
Material that is constantly kept in stock .A stock material has a material master record and is managed on a value basis in a material stock account.
Ex: Raw Material.
Non-stock Material
Material that is not held in stock because it is consumed immediately.
Ex: Office Stationary.
You need to create purchase order and accounting document for payment but the stock balance is always zero as it is issued out immediately to the various department.

Column cannot convert between unicode and non-unicode string data types

I am converting SSIS jobs from SQL Server 2005 running on a Windows 2003 server to 2008R2 running on a Windows 2008 server.  I have a dataflow with an OLE DB Source which is selecting from an Oracle view.  This of course worked fine in
2005.   This OLE DB Source will not even read the data from Oracle without the error "Column "UWI" cannot convert between unicode and non-unicode. The select is:
SELECT SOME_VIEW.UWI AS UWI,
CAST(SOME_VIEW.OIL_NET AS NUMERIC(9,8)) AS OIL_NET
FROM SOME_SCHEMA.SOME_VIEW
WHERE OIL_NET IS NOT NULL AND UWI IS NOT NULL
ORDER BY UWI
When I do "Show Advanced Editor" on this component, in the Input and Output Properties, I show the OLE DB External Column as DT_STR length 40 for the UWI column and for the Output Columns I see the UWI as the same DT_STR.
How can I get past this? I have tried doing a cast...cast(SOME_VIEW.UWI AS VARCHAR(40)) AS UWI and this gives the same error. The column in Oracle is a varchar2(40).
Any help is greatly appreciated. Thanks.

Please check the data type for UWI using advanced editor for Oledb Source under
external columns and output columns. Are the data types same?
If not, try changing the data type (underoutput columns) same as data type shown under
external columns

Cannot convert between unicode and non-unicode string data types.

I'm trying to copy the data from 21 tables in a SQL 2005 database to a MS Access database using SSIS. Before converting the SQL database from 2000 to 2005 we had this process set up as a DTS package that ran every month for years with no problem. The only way I can get it to work now is to delete all of the tables from the Access DB and have SSIS create new tables each time. But when I try to create an SSIS package using the SSIS Import and Export Wizard to copy the SQL 2005 data to the same tables that SSIS itself created in Access I get the "cannot convert between unicode and non-unicode string data types" error message. The first few columns I hit this problem on were created by SSIS as the Memo datatype in Access and when I changed them to Text in Access they started to work. The column I'm stuck on now is defined as Text in the SQL 2005 DB and in Access, but it still gives me the "cannot convert" error.

I was getting same error while tranfering data from SQL 2005 to Excel , but using following method i was able to tranfer data. Hopefully it may also help you.
1) Using Data Conversion transformation
data types you need to select is DT_WSTR (unicode in terms of SQL: 2005)
2) derived coloumn transformation
expression you need to use is :
(DT_WSTR, 20) (note : 20 can be replace by your character size)
Note:
Above teo method create replica of your esting coloumn (default name will be copy of <coloumn name>).
while mapping data do not map actual coloumn to the destination but select the coloumn that were created by any of above data transformer (replicated coloumn).

How to fix "cannot convert between unicode and non-unicode string data types" :/

Environment: SQL Server 2008 R2
Introduction:Staging_table is a table where data is being stored from source file. Individual and ind_subject_scores are destination tables.
Purpose: To load the data from a source file .csv while SSIS define table fields with 50 varchar, I can still transfer the data to the entity table/ destination and keeping the table definition.
I'm getting validation error "Cannot convert between a unicode and a non-unicode string data types" for all the columns.

Difference between configurable and non configurable finished goods master

Hi
Pl explain the difference between configurable and non configurable finished goods master data.
Thanks
kamala

Hi,
Configurable material are used when you have a large number of combination of parts that go into a product. It means different combinations of the parts for same material. If you maintain a unique material code for each combination , you require a large number of material numbers. KMAT is used in such a case where you maintain just one generic product code. You assign class to this material having all variant characteristics.
A super BOM is maintained for such a material consisting of all possible alternatives. A super routing is also maintained consisting of all possible operations that could be used.
Typically configurable material is used in Made To Order (MTO) environment. However frequently ordered configurations may be planned with a material variant which needs to have a material master record. Thus Material variants may have stock and value. Depending upon characteristic values chosen at sales order entry Sales Order BOM is created. Routing operations are also chosen depending upon which BOM components are assigned to them.
Non configurable materials are like finish, semi finish materials having fixed BOM. A separate/single BOM exits for every finish material.

thanks and regards,

Unicode and non-unicode

WHAT IS DIFFRENTS BETWEEN UNICODE AND NON UNICODE ?
BRIEFLY EXPLAIN ABOUT UNICODE?
THANKS IN ADVANCES

A 16-bit character encoding scheme allowing characters from Western European, Eastern European, Cyrillic, Greek, Arabic, Hebrew, Chinese, Japanese, Korean, Thai, Urdu, Hindi and all other major world languages, living and dead, to be encoded in a single character set. The Unicode specification also includes standard compression schemes and a wide range of typesetting information required for worldwide locale support. Symbian OS fully implements Unicode. A 16-bit code to represent the characters used in most of the world's scripts. UTF-8 is an alternative encoding in which one or more 8-bit bytes represents each Unicode character. A 16-bit character set defined by ISO 10646. A code similar to ASCII, used for representing commonly used symbols in a digital form. Unlike ASCII, however, Unicode uses a 16-bit dataspace, and so can support a wide variety of non-Roman alphabets including Cyrillic, Han Chinese, Japanese, Arabic, Korean, Bengali, and so on. Supporting common non-Roman alphabets is of interest to community networks, which may want to promote multicultural aspects of their systems.
ABAP Development under Unicode
Prior to Unicode the length of a character was exactly one byte, allowing implicit typecasts or memory-layout oriented programming. With Unicode this situation has changed: One character is no longer one byte, so that additional specifications have to be added to define the unit of measure for implicit or explicit references to (the length of) characters.
Character-like data in ABAP are always represented with the UTF-16 - standard (also used in Java or other development tools like Microsoft's Visual Basic); but this format is not related to the encoding of the underlying database.
A Unicode-enabled ABAP program (UP) is a program in which all Unicode checks are effective. Such a program returns the same results in a non-Unicode system (NUS) as in a Unicode system (US). In order to perform the relevant syntax checks, you must activate the Unicode flag in the screens of the program and class attributes.
In a US, you can only execute programs for which the Unicode flag is set. In future, the Unicode flag must be set for all SAP programs to enable them to run on a US. If the Unicode flag is set for a program, the syntax is checked and the program executed according to the rules described in this document, regardless of whether the system is a US or a NUS. From now on, the Unicode flag must be set for all new programs and classes that are created.
If the Unicode flag is not set, a program can only be executed in an NUS. The syntactical and semantic changes described below do not apply to such programs. However, you can use all language extensions that have been introduced in the process of the conversion to Unicode.
As a result of the modifications and restrictions associated with the Unicode flag, programs are executed in both Unicode and non-Unicode systems with the same semantics to a large degree. In rare cases, however, differences may occur. Programs that are designed to run on both systems therefore need to be tested on both platforms.
