Differnce

Hi All,
If I declared a column as Unique as well as Not null then what is the use of primary key...Is there any advantage while use primary key...
Thanks and Regards
MK

Some additional info on key data: Any combination of non nullable columns that are unique when taken together due to not null and unique index constraints may be considered a candidate key. Additionally if the all of the columns in that candidate key store relevent data, the combination of columns can be conserdered to be a natural key. However, the one big difference between these candidate keys (natural or otherwise) and a primary key is that primary keys should be immutable. Enforcing an immutable requirement on a natural key would prevent a user from ever correcting miss entered data. That's one reason why in general it is best to use a uniquely generated value as your primary key. Such a key value is called a surrogate key becuase it is used in place of a natural key.

Differnce b'w lsmw and bdc

pls tell the differnce b'w lsmw and bdc . when we use bdc and when we use lsmw .for uploading master data (ex: cusomer data ) in tosap which method s u prrefer out of thhse 4
method scall transaction
session input
lsmw bapi whic one is the better one
when use session method and when we use call tran sac
which method is better for bacjground processing call tran s or session method . pls tell
the reason
answres as soon as possible

Hi,
LSMW IS JUST A TOOL TO GET THE DATA FROM A LEGACY SYSTEM.
IN BDC WE HAVE 2 WRITE THE CODE AND CALL THE REQUIRED METHOD
THATS IT. IN FUNCTIONALITY PERSPECTIVE THERE IS NO
DIFFERENCE.
BDC is Batch Data Communication. It is basically a program
either generated by SAP after a recording or programmed by a
abaper.Its like running the transaction manually but all the
data is populated on the screens automatically.It is a
little complex when the screens contain table controls.
LSMW is legacy system migration workbench is a more user-
friendly tool thru which one can do the same as a BDC. One
just has to follow some 14 steps, click buttons and the data
is set to be uploaded ….LSMW offer you 4 ways to import data
into SAP, they are BDC, Direct Input, BAPI(BO), IDOC.
To spell out the differences in detail:

Basic differnce between 000 and 001 clients.

what is the basic differnce between 000 and 001 clients?
why do we use client 000 as source client while client copy?

Hi Kumar
The basic difference between Client 000 and Client 001 is that Client 000 is client independent instace while Client 001 is Client dependent.
Client 000 is SAP source client while Client 001 doesn't exits for every installation.

Differnce between SAP-XI and SAP PI

hi can any body tell me what is the differnce between SAP-XI and SAP-PI

Hi vijay,
u can get lot of information regarding PI and XI in sdn.There already exists a no. of thread.just search with keyword "XI 3.0 and PI 7.0" u can get a lot.
XI 3.0
1. J2Se adapter engine was replaced with J2EE Adapter Engine.
2. BPM was available from XI 3.0
3. Part of Netweaver 2004
PI 7.0
1XI renames as Process Integration
2.. Part of Netweaver 2004s.
3. Has all features of XI 3.0 and every SP of Pi 7.0 has a corresponding release for XI 3.0.
4. Runs on WAS 7.0 and has same features as XI 3,0
From functional point, there is no difference between XI3.0 and PI7.0. There are changes only wrt SP. For every SP release on PI7.0 a corresponding SP for XI3.0 is also released.
A comparision of the service packs in 2004 and 2004s;
in 2004 - in 2004s
SP12 & < - SP04
SP13 + 14 - SP05
SP15 - SP06
SP16 - SP07
SP17 - SP08

For release notes
ref:http://help.sap.com/saphelp_nw04/helpdata/en/cf/9844428e9cbe30e10000000a155106/frameset.htm
There is no f'nal difference between XI 3.0 and PI 7.0. In order to bring all netweaver releases on par with each other , SAP released / renamed XI as PI and it is a part of NW04s
For every release of PI 7.0, there is a parallel Support Pack on XI.

Differnce between AT NEW AND ON CHANGE OF

Hi,
Differnce between AT NEW AND ON CHANGE OF
Iam waiting foryour reply
Thanks & Regards
Raja Sekhar.T

Hai Raja
check the following Documents
1. AT NEW f.
2. AT END OF f.
3. AT FIRST.
4. AT LAST.
5. AT fg.
Effect
In a LOOP which processes a dataset created with EXTRACT , you can use special control structures for control break processing. All these structures begin with AT and end with ENDAT . The sequence of statements which lies between them is then executed if a control break occurs.
You can use these key words for control break processing with extract datasets only if the active LOOP statement is proceesing an extract dataset.
The control level structure with extract datasets is dynamic. It corresponds exactly to the sort key of the extract dataset, i.e. to the order of fields in the field group HEADER by which the extract dataset was sorted .
At the end of a control group ( AT END OF , AT LAST ), there are two types of control level information between AT and ENDAT :
If the sort key of the extract dataset contains a non-numeric field h (particularly in the field group HEADER ), the field CNT(h) contains the number of control breaks in the (subordinate) control level h .
For extracted number fields g (see also ABAP/4 number types ), the fields SUM(g) contain the relevant control totals.
Notes
The fields CNT(h) and SUM(g) can only be addressed after they have been sorted. Otherwise, a runtime error may occur.
The fields CNT(h) and SUM(g) are filled with the relevant values for a control level at the end of each control group ( AT END OF , AT LAST ), not at the beginning ( AT FIRST , AT NEW ).
When calculating totals with SUM(g) , the system automatically chooses the maximum field sizes so that an overflow occurs only if the absolute value area limits are exceeded.
You can also use special control break control structures with LOOP s on internal tables.
Variant 1
AT NEW f.
Variant 2
AT END OF f.
Effect
f is a field from the field group HEADER . The enclosed sequence of statements is executed if
the field f occurs in the sort key of the extract dataset (and thus also in the field group HEADER ) and
the field f or a superior sort criterion has a different value in the current LOOP line than in the prceding ( AT NEW ) or subsequent ( AT END OF ) record of the extract dataset.
Example
DATA: NAME(30),
      SALES TYPE I.
FIELD-GROUPS: HEADER, INFOS.
INSERT: NAME INTO HEADER,
        SALES INTO INFOS.
LOOP.
AT NEW NAME.
    NEW-PAGE.
ENDAT.
AT END OF NAME.
    WRITE: / NAME, SUM(SALES).
ENDAT.
ENDLOOP.
Notes
If the extract dataset is not sorted before processing with LOOP , no control level structure is defined and the statements following AT NEW or AT END OF are not executed.
Fields which stand at hex zero are ignored by the control break check with AT NEW or AT END OF . This corresponds to the behavior of the SORT statement, which always places unoccupied fields (i.e. fields which stand at hex zero) before all occupied fields when sorting extract datasets, regardless of whether the sort sequence is in ascending or descending order.
Variant 3
AT FIRST.
Variant 4
AT LAST.
Effect
Executes the relevant series of statements just once - either on the first loop pass (with AT FIRST ) or on the last loop pass (with AT LAST ).
Variant 5
AT fg.
Addition
... WITH fg1
Effect
This statement makes single record processing dependent on the type of extracted record.
The sequence of statements following AT fg are executed whenever the current LOOP record is created with EXTRACT fg (in other words: when the current record is a fg record).
Addition
... WITH fg1
Effect
Executes the sequence of statements belonging to AT fg WITH fg1 only if the record of the field group fg in the dataset is immediately followed by a record of the field group fg1 .
Basic form
ON CHANGE OF f.
Addition
... OR f1
Effect
Executes the processing block enclosed by the " ON CHANGE OF f " and " ENDON " statements whenever the contents of the field f change (control break processing).
Normally, you use the statement to manipulate database fields during GET events or SELECT / ENDSELECT processing.
Note
There are special control structures for processing control breaks in LOOP s on internal tables or extract datasets AT ).
ON CHANGE OF is unsuitable for recognizing control levels in loops of this type because it always creates a global auxiliary field which is used to check for changes. This global auxiliary field can only be changed in the relevant ON CHANGE OF statement. It is not reset when the processing goes into loops or subroutines, so unwanted effects can occur if the loop or subroutine is executed again. Also, since it is set to its initial value when created (like any other field), any ON CHANGE OF processing will be executed after the first test, unless the contents of the field concerned happen to be identical to the initial value.
Example
TABLES T100.
SELECT * FROM T100 WHERE SPRSL = SY-LANGU AND
                         MSGNR < '010'
                   ORDER BY PRIMARY KEY.
ON CHANGE OF T100-ARBGB.
    ULINE.
    WRITE: / '**', T100-ARBGB, '**'.
ENDON.
WRITE: / T100-MSGNR, T100-TEXT.
ENDSELECT.
Displays all messages with their numbers in the logon language, provided the number is less than '010'.
Each time the message class changes, it is output.
Addition
... OR f1
Effect
Also executes the code whenever the contents of the field f1 changes.
You can use this addition several times.
Example
Logical database F1S
TABLES: SPFLI, SFLIGHT, SBOOK.
GET SBOOK.
ON CHANGE OF SPFLI-CARRID   OR
               SPFLI-CONNID   OR
               SFLIGHT-FLDATE.
    ULINE.
    WRITE: /5 SPFLI-CARRID, SPFLI-CONNID,
            5 SFLIGHT-FLDATE, SPFLI-FLTIME,
            5 SFLIGHT-SEATSMAX, SFLIGHT-SEATSOCC.
ENDON.
WRITE: / SBOOK-CUSTOMID.
The code between ON CHANGE OF and ENDON is executed only if at least one of the fields SPFLI-CARRID , SPFLI-CONNID or SFLIGHT-FLDATE has changed, i.e. there is a different flight connection (which also has bookings).
Notes
Thanks & regards

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

Periodic billing is used when you want to bill the customer at different points of time based on the periodicity or progress of the work. Milestone billing can be used for this type of billing purposes when you want to have billing control from the project.
Resource billing is based on the resource consumption for the particular activities. Dynamic Item Processor (DIP) profile is used for the resource related billing.

Hi ,
/n ends the particular transaction .
/bend - This means batch end .
This comes only in BDC concept .This is where you transfer data from the legacy system to sap R/3 system .When you are performing recording process and you dont want to continue any more you give /bend .

Differnce between business name and physical name

What is the differnce between business name and physical name in OWB

Hi Vibhuti,
What I have noticed is that Physical name is THE important thing that is required while importing and synchronising. It has a length limitation of 30. The mappings appear with this name in the left panel in design center. The Business name is just for reference I believe.

STO DIFFERNCE BETWEEN UB AND NB

HI all
can someone plz tell me the differnces between po type NB and UB
and y do we use UB for Intra Company and NB for Intercompany
where exactly is the contrl\ol
olz clarify

hi
UB: If the supplying plant and Receiving Plant belong to the same company code. then we use UB document type.
If you use own document type you should ensure transport control field.
NB : If the Supplying plant and Receiving plant belong to different company code then use document type NB.
difference : IF the company need billing document for stock transfer use NB document.
else use UB document for the stock transfer .

Differnce between getCurrentRow() and firrst() method

Hi
what is the differnce in vo.getCurrentRow() and vo.first().
I have executed one view which returns only one row.When i use vo.getCurrentRow() I get null but vo.first() gives the row.
What the reason can be???
Naveen

what is the differnce in vo.getCurrentRow() and vo.first().
As the name suggests getCurrentRow, gives the row at which Vo pointer is at that moment of time, while getFirstRow, will always give u the first row.I have executed one view which returns only one row.When i use vo.getCurrentRow() I get null but vo.first() gives the row.
When u execute the VO query , your VO pointer is just above the first row, so points to no row, this is very similar, to resultset in jdbc, while when u do vo.first(), pointer gives the first row.I hope this is clear.
