Wht r the advantages of using bdc rathan than lsmw?

Hi , I want to knwo.. wht r the advangtages of using bdc rathan than lsmw.,,,

Hi,
LSMW and BDC are vastly different.
BDC (Batch Data Communication) is a technology used for data transfer.
it is meant for transferring data thru SAP transactions itself. when u use BDC for data transfer,
the sequence of steps is the same as when u use standard sap transaction screens for data upload. the only difference is that u can use different options for foreground/background processing.
LSMW on the other hand is a tool that helps migrate data from a legacy system (non-sap system ) to SAP system.
it offers u various options to use either batch input, direct input, BAPIs or idocs.
it involves a series of some 17-18 steps to migrate data.
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system
or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as ‘CLASSICAL METHOD’.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Session method is to populate the data by filling BDC structure
and keep as session to process from SM37 to post in appropriate Transaction.
Call transaction method is to post the data directly into the Transaction from an Executable program.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

LSMW:
The LSM Workbench is an R/3-based tool that supports You when transferring data from non-SAP systems ("Legacy Systems") to R/3 once or periodically.
The tool supports conversion of data of the legacy system in a convenient way. The data can then be imported into the R/3 system via batch input, direct input, BAPIs or IDocs.
Furthermore, the LSM Workbench provides a recording function that allows to generate a "data migration object" in an entry or change transaction.
The main advantages of the LSM Workbench:
• Part of R/3 and thus independent of individual platforms
• A variety of technical possibilities of data conversion:
• Data consistency due to standard import techniques:
Batch input
Direct input
BAPIs (Business Application Programming Interfaces)
IDocs (Intermediate Documents)
The import technique to be used in an individual case depends on the business object.
• Generation of the conversion program on the basis of defined rules
• Clear interactive process guide
• Interface for data in spreadsheet format
• Creation of data migration objects on the basis of recorded transactions
• Charge-free for SAP customers and SAP partners

  • Advantage of using BDC

    Hi Experts,
       What is the advantage of using BDC upload??. Even if there is only a single record , that record should be uploaded through a BDC program.  I can upload the data through a report also. Then why BDC is preffered?

    The purpose of the Batch Data Communication is to transfer data. The BDC can transfer data from one SAP System to another SAP System or can transfer data from non-SAP System to SAP System too. To transfer data BDC uses normal transaction codes. Two methods are provided to BDC to do this work.
    SAP has provided two different types of methods for BDC to do its work. Among these, the first one is called the classical method or session method. Through this method the data can be read by the BDC program from a sequential dataset file. This sequential dataset file is stored in batch-input session. In order to .run the transaction in this session, what one needs is to execute the session. For this, follow these few steps: you can start and subsequently monitor the session firstly from – System à Services à Batch Input or have the session run in the background. In this method to generate the required session, you have to use the function module BDC _ NSERT and BDC _CLOSE.
    In the second method the BDC has to use the ABAP statement CALL TRANSACTION USING statement to run a transaction. In the second method, unlike in the first type, you do not need BDC to create a session.
    when comming to ur question... generally bdc are used to uplad large amount of data.  mostly not used for single record...
    once if u have a bdc prg then u can call it to uplad more than a single record....  any time.....

  • If I use the same iCloud account for my ipad and iPhone, will changes I make on one change on the other as well?  I'm not sure of the advantage of using teh same iCloud for both devices.

    If I use the same iCloud account for my ipad and iPhone, will changes I make on one change on the other as well?  I'm not sure of the advantage of using teh same iCloud for both devices.

    No, it only mirrors changes to synced data.  This includes mail, contacts, calendars, reminders, safari bookmarks, notes, iWork documents and data, and photo stream photos (assuming you choose to sync all this data).  Changes to iTunes data such as music, apps, podcasts, etc., are not synced using iCloud.  In your example, if you delete an app from one device it will remain on the other until deleted there too.

  • What are the advantage of using a passive monitoring technique ?

    What are the advantage of using a passive monitoring technique

    Hi Plawansai,
    I saw your question that is still unanswered.
    I believe an advantage of using a passive monitoring technique is that it won't interfer with live traffic, as it does not inject traffic into the network or modify the traffic that is already on the network.
    One drawback anyway, is that post-processing time can take a large amount of time with passive monitoring!
    A combination of the two monitoring methods seems to be the route to go.

  • What are the advantages of using Map IDs?

    Hi:
    I am trying to find out the advantages for using map ids as
    opposed to just using the file names for the topics, but I couldn't
    find this information in the RH7 Help or the forums. Can you please
    list the advantages and disadvantages.
    Also, I am describing how I wish to implement the context
    sensitive help feature for my application and you can tell me which
    approach is better. We make an application that is packaged within
    a Java IDE. We want to launch context sensitive help topics from
    the wizards and cheat sheets. Now, this context sensitive help can
    be either be installed on the local machine or network (file://
    protocol) or available on our portal (https:// protocol). We do
    have the infrastructure in place to let the user decide whether
    he/she wants to access the local help topic or the one over the
    internet. Will map ids work for both the scenarios?
    Thanks,
    K

    It sounds like your application call needs to call an online
    version of the help first and if this is not available to point to
    a local copy. Is that right? If so, how this happens is entirely in
    the hands of your developers. I know it can be done, just sketchy
    on the actual procedure.
    As far as the CSH in the help is concerned, you can use
    mapids for both versions of the help if you want. If using webhelp
    you'd do well to check out
    this
    link on Peter Grainge's site.

  • What is the advantages of using Flexconnect groups

    what is the advantages of using Flexconnect groups in WLC?
    Reg,
    Ezra.

    Pls refer this document for more detail about these features
    http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/emob73dg/emob73/ch7_HREA.html#wp1091114
    FlexConnect is one mode an AP can operate, typically deployed in Branch setup where you do not have a controller at branch site. Those AP can register to a controller at your HQ or main site. So traffic will terminate at your branch switch instead of tunnel back to HQ-WLC.
    If you want roaming within your branch FlexConnect AP then you have to put those AP into a FlexConnect Group. Then only key information shared among those AP to facilitate fast roaming.
    Pls do not forget to rate our responses if you find them useful.

    Hi,
    Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

    Hi,
    There are various differences between the two.
    1. SQL Server is only Windows, but Oracle runs on almost all Platforms.
    2. You can have multiple databases in SQL Server, but Oracle provides you only one database per instance.Given that the very term 'database' has s different meaning in the two products, this "difference" is absolutely meaningless.
    3. SQL Server provides T-SQL for writing programs, whereas Oracle provides PL/SQLWhich means what? Both products have a procedural programming language. They named them differently, and the languages are not interchangeable. Means nothing in comparing the features/strengths/weaknesses/suitability to purpose.
    4. Backup types in both are the same. (Except Oracle provides an additional backup called Logical Backup.)You make that sound like "Logical Backup" is something more than it is. It is nothing more than an export of the data and metadata. Many experts don't even consider it a backup. I'm sure SQL Server provides the same functionality though they probably call it by some other name.
    5. Both provide High Availability.Well, I guess they both have a suite of features they refer to as "High Availability". But what does that really mean? The devil is in the details. Remember, the two products don't even agree on what constitutes a "database".
    6. Both come in various distributions.???

    If you are going for an Implementation, you can try SQL Server Express Edition and Oracle XE which are free to use.
    Then you can choose whichever is comfortable for your needs.

    what is workflow ? What are the advantages of using workflow? What are the steps for building a workflow ?

    Hi Leela,
    Your question is very straight question.
    Better u can follow these links.
    http://www.esnips.com/doc/90b7763b-f9d9-4861-a273-04674b9fe3f2/Workflow
    http://www.esnips.com/doc/991843e0-8686-4949-94b9-f45d90081b22/workflow
    And i'll give some theory answer for ur questions
    i.e.,SAP Business Workflow can be used to define business processes that are not yet mapped in the R/3 System. These may be simple release or approval procedures, or more complex business processes such as creating a material master and the associated coordination of the departments involved. SAP Business Workflow is particularly suitable for situations in which work processes have to be run through repeatedly, or situations in which the business process requires the involvement of a large number of agents in a specific sequence.
    You can also use SAP Business Workflow to respond to errors and exceptions in other, existing business processes. You can start a workflow when predefined events occur, for example an event can be triggered if particular errors are found during an automatic check.
    SAP provides several workflows that map predefined business processes. These workflows do not require much implementation. For an overview of these SAP workflows, refer to Workflow Scenarios in Applications.
    Integration
    SAP Business Workflow uses the existing transactions and functions of the R/3 System and does not change the functions. You can combine the existing functions of the R/3 System to form new business processes with SAP Business Workflow. The workflow system takes over control of the business processes. If you are already using SAP Organizational Management, you can use the organizational structure created there to have the relevant agents carry out the individual activities. It is possible to have an activity carried out by a position. This ensures that the respective occupiers of the position can carry out the individual activities during execution of the workflow. This means that personnel changes in your organization are taken into account immediately in the execution of a workflow.
    Features
    SAP Business Workflow provides a number of tools for defining and analyzing workflows as well as for monitoring operation.
    The Workflow Builder is for displaying and making changes to workflows. You can make small extensions directly to the original workflows supplied by SAP, such as carrying out your own agent assignments or changing deadline monitoring.
    There are several Workflow Wizards to support you in the definition of workflows, with which you can create specific parts of a workflow. The Workflow Wizard Explorer gives you an overview of the existing Workflow Wizards.
    In order to make the functions of the R/3 Systems available to a workflow, you use business objects, which you can define and analyze in the Business Object Builder. These business objects are made available to the workflow in reusable tasks. The Business Wizard Explorer gives you an overview of all existing tasks.
    The end user receives information about the activities they are to carry out in their Business Workplace. This provides them with a central overview of all the activities that they are authorized to carry out. They can commence the activities from here.
    Several tools are available to the workflow system administrator, with which they can control and analyze the current workflows. The workflow system administrator is notified of problems automatically by the system.

  • What are the advantages of using cirrus for multiuser applications ?

    Hi!
    Can anybody help me understanding the advantages of using cirrus for multiuser apps ?
    One advantage i think, may be it's free . Isn't it ?  Anything else ( say, it's faster .? )

    The main advantage is that it is a P2P system. It is not the same as a Flash Media Server or other Flash servers. When using Cirrus, your content is sent directly to and from clients, they do not need to send it to the server, get it interpreted and then send it to the other user.
    So essentially Cirrus is fantastic if you have an application envrionment that needs multiuser interaction, but only for client to client operations: you'd want peer-to-peer.

  • What are the advantages of using an internal table with workarea

    Hi,
    can anyone tell me
    What are the advantages of using an internal table with workarea
    over an internal table with header line?
    thnks in adv
    regards
    nagi

    HI,
    Internal tables are a standard data type object which exists only during the runtime of the program. They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.
    http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb35de358411d1829f0000e829fbfe/content.htm
    <b>Difference between Work Area and Header Line</b>
    While adding or retrieving records to / from internal table we have to keep the record temporarily.
    The area where this record is kept is called as work area for the internal table. The area must have the same structure as that of internal table. An internal table consists of a body and an optional header line.
    Header line is a implicit work area for the internal table. It depends on how the internal table is declared that the itab will have the header line or not.
    e.g.
    data: begin of itab occurs 10,
    ab type c,
    cd type i,
    end of itab. " this table will have the header line.
    data: wa_itab like itab. " explicit work area for itab
    data: itab1 like itab occurs 10. " table is without header line.
    The header line is a field string with the same structure as a row of the body, but it can only hold a single row.
    It is a buffer used to hold each record before it is added or each record as it is retrieved from the internal table. It is the default work area for the internal table
    1) The difference between
    whih header line and with out heater line of internal table.
    ex:-
    a) Data : itab like mara occurs 0 with header line.
    b) Data: itab like mara occurs 0.
    -While adding or retrieving records to / from internal table we have to keep the record temporarily.
    -The area where this record is kept is called as work area for the internal table.
    -The area must have the same structure as that of internal table. An internal table consists of a body and an optional header line.
    -Header line is a implicit work area for the internal table. It depends on how the internal table is declared that the itab will have the header line or not.
    a) Data : itab like mara occurs 0 with header line.
    table is with header line
    b) Data: itab like mara occurs 0.
    table is without header line
    2)work area / field string and internal table
    which one is prefarable for good performance any why ?
    -The header line is a field string with the same structure as a row of the body, but it can only hold a single row , whereas internal table can have more than one record.
    In short u can define a workarea of an internal table which means that area must have the same structure as that of internal table and can have one record only.
    Example code:
    data: begin of itab occurs 10,
    ab type c,
    cd type i,
    end of itab. " this table will have the header line.
    data: wa_itab like itab. " explicit work area for itab
    data: itab1 like itab occurs 10. " table is without header line.

  • What are the advantages of using LabVIEW projects in TestStand, as apposed to just a path to a vi

    What are the advantages of using LabVIEW projects in TestStand, as apposed to just a path to a vi ?
    I am modifying an existing workspace for a new product, and it seems like more work to add the vi's into a LabVIEW project
    does it gain anything in the long run

    Hi Rusty,
    I wanted to quickly clarify on the integration between TestStand and LabVIEW Projects.
    As Jeff mentioned, some of the big benefits of using LabVIEW Projects is to organize code and to namespace them.
    For instance if you had a project called "Power Supply" that housed all your power supply code and had a VI in that called "Initialize", and another project called "Temperature Chamber" that also had a VI called "Initialize", both these VIs are namespaced by the project, so there is no longer confusion about which "Initialize" VI is being used.
    Now from a TestStand point of view, in prior version of TestStand, we lost some of this benefit because TestStand did not know about TestStand projects and called VIs simply as un-namespaced VIs. However, in TestStand 2010 (released last year, free eval available at ni.com/teststand), we added the ability to (optionally) call VIs within the context of their projects. This means that:
    VIs are now namespaced by their project, even when called from TestStand
    VIs can use project specific constructs like NI-DAQmx tasks and conditional compilation settings
    Note: When creating deployments, the VIs maintain their projects and namespacing, so this benefit holds true for deployments as well.
    Additionally, someone had mentioned looking into using lvlibs to namespace your VIs for deployment. Two comments:
    With TestStand 2010, this is no longer neccessary since the project itself namespaces the VIs
    You might also want to look into LabVIEW Packed Project Libraries, which combined several VIs into a single file. Think of it as a DLL specific to LabVIEW that is as easy to call as normal LabVIEW VIs. TestStand 2010 can call VIs that are exposed by PPLs. In addition, the deployment utility can automatically pack your VIs into PPLs for deployment.
    Hope this is helpful!
