Diff.Between Class.GL and NewGL

We are implementing BCS 6.0 based on Old GL ( Class.GL) Suppose in future we migrated to New GL, what is the impact on BCS?
Do we need to re-implement BCS ?
Thank you very in advance.
Anna

Hi Anna,
The following is an architecture of BCS implementations I use:
- ERP (or other source systems)
I
- BW layer with
-- cube for extracting data from ERP
-- intermediate cube
-- BCS totals cube
I
- SEM-BCS system.
In update rules of intermediate cube I perform data transformation (adding analytical characteristics, transformation of key figure model (debit - credit - balance) into account model (item - movement type), mapping of accounts (from flat chart of accounts in ERP to multidimensional in BCS), etc.).
This cube will be used for reading data from datastream in BCS. For better performance this cube is made as much similar to BCS totals cube as possible.
So, if you have the same architecture, you'll just modify extractors and, probably, the structure of the 1st cube, and probably, update rules in the 2nd one (intermediate).
All the rest (including ALL settings in SEM-BCS) is going to left intact.
If the architecture is different -- everything will be dependent on it.
Hope this helps.

Diff between object based and ob. oriented

diff between object based and ob. oriented

Object-oriented requires at least three factors:
1. Encapsulation: Combining data and the methods that manipulate the data into a self-contained unit called an "object" in which the data is hidden from the user and only the method interface is visible.
2. Inheritance: Ability of a class to extend the features of another class by obtaining all the public features of the other class while adding its own specialized features (Example: Great Dane inherits from Dog)
3. Polymorphism: The ability to perform "late binding" by invoke methods of a subclass on behalf of its superclass. (Polymorphism includes other things and it difficult to explain.
If a language does not include all three, it is called "object-based." Visual Basic 6 is object-based, because it allows you to define classes that encapsulate, but doesn't support an inheritance hierarchy nor polymorphism.

what is the differene between class diagram and er diagram .....pls explain with examples

<b>Diff btw Class Diagrams and ERD's:</b>
Class diagrams and ERDs both model the structure of a system. Class diagrams
represent the dynamic aspects of a system: both the structural and behavioural features.
ERDs, depicting only structural features provide a static view of the system.
Elements of a class diagram:
>class
>association
>binary
>n-ary
>Aggregation
>Composition
>Generalization
>Dependency
>Realization
>Association Classes
Elements of Entity Relationship Diagrams:
>Entity - A data attribute is a property common to an entity.

In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

hello all
In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

Hi Swamy,
The differences between IDoc and BAPI are as follows:
IDOC
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system.
Idocs are processed asynchronously and no information whatsoever is returned to the client.
The target system need not be always online. The IDOC would be created and would send the IDOC once the target system is available (tRFC concept). Hence supports guaranteed delivery.
With asynchronous links the sub-process on the client can be finished even if the communication line or the server is not available. In this case the message is stored in the database and the communication can be done later.
The disadvantage of asynchronous links is that the sub-process on the server cannot return information to the calling sub-process on the client. A special way for sending information back to the client is required. In addition, a special error handling mechanism is required to handle errors on the receiving side.
IDOCs may be more changeable from release to release.
IDOCs are poorly documented.
BAPI
BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
BAPIs are called synchronously and (usually) return information.
For BAPIs the client code needs to do the appropriate error handling.
Problems with synchronous links occur if the communication line or the server is temporarily not available. If this happens, the sub-process on the client cannot be finished (otherwise there would be data inconsistencies).
Synchronous links have the advantage that the sub-process on the server can return values to the sub-process on the client that has started the link.
BAPIs are not totally immune to upgrades.
BAPIs are reasonably well documented.
Reward points if useful.

Sekhar

Diff between Thin client and Rich client

Hi Everyone,
Can someone give me a clear picture of the what is the diff between Thin client and Rich client.
Thanks,
Krishna

Hi,
thick client (rich client) has/stores all the data inside itself
so it can do application processing without the server with data
thin client uses resources from host computer (from server)
and wihtout that you are not able to work with that kind of client
does that answer your question ?

Diff between Seeburger Adapter and File Adapter

Hi All,
My company needs to interact with some banks and the banks are particular that they want SFTP, which is not supported by File Adapter, so we have decided to go with Seeburger adapter.
Now what are the differences between File adapter and seeburger adapter?
I believe that Seeburger adapter does not support File Content Conversion, Archiving etc.
Could you all pls put some light on the diff between file adapter and seeburger adapter when it comes to dealing with files?
Xier

Hi
You are aware with working of File Adapter.
The most direct way of using the Seeburger adaptors is to configure the BIC as a module. There is a software component from seeburger called bicmapper which will allow you to
1. Define or import the inbound message metadefinition in various formats ( edifact, xml,...)
2. Using a mapping create an xml variant as the output metadefinition or edifact in the other direction.
3. Create a one to one mapping between input en output.
4. Export the metadata in xsd or sda format for import in XI
5. Generate an SDA which can be deployed in XI and used as a module.

Diff. between Tax Code and Condition Types

Hi,
What is the diff. between Tax Code and Condition Type???
Why we maintain Tax Codes under Invoice Tab in PO, when Condition Types are available for Calculation Procedure...???
Please guide..

hi..
Tax code : Tax code in some what more specific for calculating the tax...some material is having 2% tax..some having 3 % tax..etc..and these are input tax...so..these tax code will be of type input tax..
now..based on the nature of tax type amount will be calculated....
suppose tax code is calculation of 2 condtion type so ..we can do it in tax code conditon record fv11 also..
so..tax code can be a combination of cond type...
where as through cond type also we can also achieve this..by using one statistical cond type...
Cond Type : cond type is for the daily pricing configuration..how system will calculate the price for a centain material we can make define the rules here...
Try this out..

Diff between interactive report and interactive alv

Diff between interactive report and interactive alv? Suppose I have been given certain program then how I will diffrentiate that this prog should be done in interactive alv or interactive report.

hi
both are used for same purpose
interactive report means an output list which displays basic details & allow user to interact, so that a new list is populated based on user-selection. With interactive list, the user can actively control data retrieval and display during the session.
I suggest to use ALV.by using ALV we can display in Grid as well as list format.
Output format will be good . Sorting,Filtering facilities are provided by itself.We can have column headings also.
if helpful reward points

Is there any Similar between Class.forName() and new operator ???

Plz tel me is there any Similar between Class.forName() and new operator ??? i have been asked this ques in interview

You probably should have used the other thread:
http://forum.java.sun.com/thread.jspa?threadID=792678
To add a little confusion to the matter...Class objects are in fact objects. They're objects representing classes. So, in a sense, I guess, you could say they're similar -- in each you get an object. But in practice Class objects and all other objects should be considered semantically different unless you're doing some pretty unusual stuff. Also Class.forName is more of a factory method than a constructor.

Diffrence between Class.forName() and new Operator

What is diffrence between class.forName() and new operator.Please tell in much detail.
Also about classloader.loadclass.
Suppose the class that we are tring to load with the help of class.forname is not compiled. Again if I make changes at runtime to that class will that get reflected.

What is diffrence between class.forName() and new
operator.Please tell in much detail.Class.forName loads a class. The new operator creates a new instance. Apple trees and apples.
Also about classloader.loadclass.Read the API.
Suppose the class that we are tring to load with the
help of class.forname is not compiled.Then you can't load it and get an exception. Read the API.
Again if I
make changes at runtime to that class will that get
reflected.Depends on the changes and when exactly you do them.

What exactly is the diff between main window and variable window

what exactly is the diff between main window and variable window in SAP script?

hi,
MAIN WINDOW :- In a main window you display text and data, which can cover several pages (flow text). As soon as a main window is completely filled with text and data, the system continues displaying the text in the main window of the next page. It automatically triggers the page break.
You can define only have one window in a form as main window.
The main window must have the same width on each page, but can differ in height.
A page without main window must not call itself as next page, since this would trigger an endless loop. In such a case, the system automatically terminates after three pages.
VARIABLE WINDOW :- The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the form.
hope this will be useful.
If useful then reward points.
with regards,
Syed

What exactly is the diff between client dependant and client independant te

Hi gurus,
What is the diff between client independant and client dependant term.. I initially had a confusion related to client independant and client dependant Transport requests, where else are these words applicable, do they apply to data as well, if so how? any links to help me understand the difference..
regards,
kishore

Hi Kishore,
Client Independant: These objects are not specific to any client. And it is universal which can be viewed,changed across the clients.
Client Dependant: These are the objects can be viewed, changed for the client for which it has been assigned. Other clients do not have access on these objects.
In SAP, all objects are finally stored as tables. "Mandt" is key field which determines whether the object is client dependant or not.
Client Independant transport requests will make the transported objects available across the clients. and Client dependent transport request make the objects available only for the client mentioned by field "Mandt"
