Differences between LSMW and BDC

Hi All
Please can you give me the few points about the differences between LSMW and BDC?
Awaiting for your Responce

THERE IS THREE TYPE OF METHOD IN BDC
BDC SESSION
CALL TRANSACTION
CALL DIALOG
What is BDC or batch input
The Batch Input is a SAP technic that allows automating the input in transactions. It lies on a BDC (Batch Data Commands) scenario.
BDC functions:
· BDC_OPEN_GROUP : Opens a session group
· BDC_CLOSE_GROUP : Closes a session
· BDC_INSERT : Insert a BDC scenario in the session
· The ABAP statement "CALL TRANSACTION" is also called to run directly a transaction from its BDC table.
It runs the program RSBDCSUB in order to launch automatically the session. The session management is done through the transaction code SM35.
The object itself is maintanable through the transaction SE24.
BDC methods:
Method
Description
Parameters
OPEN_SESSION
Opens a session
SUBRC (Return Code 0 OK)
SESSIONNAME (Session to be created)
CLOSE_SESSION
Closes a session
None
RESET_BDCDATA
Resets the BDC Internal Table...
None. Normally, for internal purpose
BDC_DYNPRO
Handles a new screen
PROGNAME (Name of the program)
DYNPRONR (Screen Number)
BDC_FIELD
Puts a value on the screen
FIELDNAME (Name of the field)
FIELDVALUE (Value to be passed)
CONSTRUCTOR
Constructor - Initializes NO_DATA
NODATA (No data character). The constructor is called automatically when the object is created.
RUN_SESSION
Launches a session with RSBDCBTC
None
CALL_TRANSACTION
Calls a transaction with the current BDC Data
MODE (Display Mode)
UPDATE (Update Mode)
TCODE (Transaction to be called)
BDC_INSERT
Inserts the BDC scenario in the session
TCODE (Transaction to be called)
BDC techniques used in programs:
1) Building a BDC table and calling a transaction,
2) Building a session and a set of BDC scenarios and keeping the session available in SM35,
3) Building a session and lauching the transaction right after closing the session.
BDC using Call Transaction
BDC using Call transaction involves calling an SAP transaction in back ground from within the ABAP
program. The process involves building an Internal BDC table containing the screen information needed to
execute the required transaction and then passing this to the Call transaction command (See code example).
The full procedure for creating a BDC program is as follows:
What is the difference between batch input and call transaction in BDC?
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.
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
BATINPUT/DIRECT INPUT
A: Batch-inputs can not be used to fill the "delivery due list" screen because it is not a dynpro. This is a standard SAP report. A SAP report (check with "System -> Status") may be called using SUBMIT sentence with the appropriate options . It is preferred to call a report than create a Batch-input program.

The LSM Workbench is an SAP R/3 based tool that supports the one-time or periodic transfer of data from non-SAP systems ("legacy systems") to SAP systems.
The LSM Workbench helps you to organize your data migration project and guides you through the process by using a clear sequence of steps.
The most common conversion rules are predefined. Reusable conversion rules assure consistent data conversion for different data objects.
LSMW vs DX Workbench
The LSM Workbench covers the following steps:
Read the legacy data from one or several files (e.g. spreadsheet tables, sequential files).
Convert the data from source format to target format.
Import the data using standard interfaces (Batch Input, Direct Input, BAPI, IDoc).
Experiences made in successful implementation projects have shown that using the LSM Workbench significantly contributes to accelerating data migration.
SAP provides this tool along with documentation to customers and partners free of charge.
Users of the LSM Workbench receive the usual support via SAP Net - R/3 Frontend (component BC-SRV-DX-LSM).
Releases:
Version 1.7.2 of the LSM Workbench ("LSMW 1.7.2") available
Attention : LSMW 1.7.2 requires an SAP R/3 system with SAP R/3 4.0 or SAP R/3 4.5.
Version 1.8.0 of the LSM Workbench (1.21mb) ("LSMW 1.8.0") available
Attention : LSMW 1.8.0 requires an SAP R/3 system with SAP R/3 4.6.
Version 3.0 of the LSM Workbench (1.89mb) ("LSMW 3.0") available for Web Application Server 6.10
Attention : LSMW 3.0 requires a SAP WAS 6.10. Functionality of version 1.7.2 and 3.0 are identical !
Version 4.0 of the LSM Workbench ("LSMW 4.0") integrated in Web Application Server 6.20
Attention : LSMW 4.0 is an integrated part of SAP WAS 6.20.

Difference between LSMW and CATT

Hi all,
Can anybody tell me the difference between LSMW and CATT?

CATT
SAP users use CATT frequently to upload master data or to
make changes to master data records. SAP Consultants and
Abapers tend to use it for creating test data. The
transactions run without user interaction. You can check
system messages and test database changes. All tests are
logged. The CATT records your keystrokes while performing
the actual transaction. You then identify the fields that
you wish to change in that view. Then export this data to a
spreadsheet to populate with the data required. This is
uploaded and executed saving you keying in the data
manually.
To perform CATT, it has to be enabled in your production
environment (your systems administrator should be able to
do this - SCC4). You will also need access to your
development system to create the CATT script.
The process of uploading data with a CATT:
Activate CATT in your client
In transaction code SCC4 - click the change button
Double click on the client number
In the Restriction section, tick Allows CATT processes to
be started.
Upload data using CATT
1. Create Import variant for the fields you need
Transaction SCAT
Goto Parameters
Create Import Variant
Goto Variant -> Edit
Goto Variant -> Fast entry or F9
Duplicate 01
2. To change the MRP Group for a list of Material
Assuming that I want to change the MRP Group for a list of
Material.
My text files should look something like this:
[Variant ID] [Variant Text] &ZDISGR &ZMATNR
--> Parameter texts MRP group Material
--> Default Values M1 A001
Changes to the default values displayed above not
effective
#01 M1 A001
#02 ''     A002
#03 M1 A003
Note : '' denotes a blank in the field. e.g. Material A002
MRP group will be replaced by a blank.
3. Configure the recorded entry fields to read from the
imported text file data
In the CATT : Maintain functions test case Screen
Double click on the Object Name
Double click on the screen number with your desired fields
Park the cursor on the fields
Click Edit -> Details
Fill in the Parameters Name and Field Contents
Finish Save it.
Assign your text file data.
In the CATT : Execute test case Screen
Click External from file and choose your text file
CATT will now read from your text file and update whatever
data you have specified.
LSMW
Using LSMW you can update any kind of data but no changes to database are allowed, where as CATT tool can update only master data, which also allows changes to the master data and also a significant testing of data is possible. LSMW is a tool that offers you 4 ways to import data into SAP, they are BDC, Direct Input, BAPI(BO), IDOC.It is used for migrating the data b/w the Non-SAP and SAP application to do for that we can take the Non-SAP application data and Converts the data into the Legacy data. After the Legacy data creation convert the data in to the "Flat file". That flat file is in the form of text file or excel format.If the file is in the form of text format
we can create the ".txt" file ("ABC.txt")and in the form of
excel ".xls" file is created. flat file for dos and .xls
file for IBM. The converted file (.txt/.xls)is either upload or download. The Upload functionality if used for .txt file to SAP and where as Downloading is the concept while SAP to .txt/.xls file.
Execute the transaction LSMW to start transfer of data,Before using the LSMW we should have good knowledge about the business object and the fields that will be transferred.
There are 14 steps that are normally used and these are :
1)   Maintain Object Attributes.
2)   Maintain Source Structures.
3)   Maintain Source Fields.
4)   Maintain Structure Relations
5)   Maintain Field Mapping and conversion rules .
6)   Maintain Fixed Values,translations ,user defined routines.
7)   Specify Files .
8)   Assign Files .
9)   Read DATA.
10) Display Read Data.
11) Convert Data.
12) Display Converted Data.
13) Create Batch Input Session.
14) Run Batch Input Sesion.

Difference in lsmw and bdc

What is the advantage of using lsmw instead of bdc whether there is any disadvantage in using 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

Differnce between lsmw and bdc

what is the diffrence between LSMW and BDC

hi
lsmw is user friendly functional consultant can do it with out technical consultant help there is no program required
bdc abaper help is needed some code should be developed
for master data uploading lsmw is suggestable
for transaction data bdc is suggestable
BDC(Batch data communication) is program tool used to load the data which program developer creates from scratch.Traditionaly this is the mechanism used to load the data.thsi you need to do technacally for this you required technical knowledge.
LSMW - Legacy System Migration Workbench SAP has developed user friendly tool for loading the data of the specific objects(vendor master, customers, orders so on) and this can be used by the functional consultant or end user without understanding the underlying program code. No ABAP knowledge is required to use this tool. This tool can be used to load the legacy data and also to conduct mass data changes in the system

Difference between sapscripts and BDCs

what is the difference between sapscripts and BDCs

BDC for data communication between sap to non sap(vice-versa)
where scripts is a business layout(we create)
bdc help
They are the only 3 methods mostly we use in BDC.

Difference between interface and bdc

Hi All,
Can anybody please explain interface and BDC.
Thanks in advance

Hi
Interface is the one which is used to transfer data from SAP to Non SAP system or NON SAP to SAP system.
BAPI, IDOC are some of the interfaces.
BDC is used to upload data from Legacy to SAP system.
Reward points if useful

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:

Hi guys,
can you please explain me the difference between lsmw and ecatt tool

Dear Lokesh,
In LSMW is used for uploading data from excel or word or note pad.like using uploding data before you start lSMW you have to assign or record your upload data
eCATT is a SAP Testing Tool, which can be used to automate & test business scenarios in R/3. One can create and execute the eCATT scripts based on business processes mapped in R/3. These scripts can be then tested before go live to Production server. If needed eCATT can be used in production server also provided exact functionality of its usage should be known. After testing, eCATT generates a detailed log depending on the processes executed. If the testing is smooth with success mode, this means the business scenarios mapped in R/3 system are correct. And if the test results in error than one can analyze the problems from the generated error log. Thus helps in analyzing the error.
What Are The Various Ways Of Doing Testing?
Testing can be done by various ways like Manually, using CATT etc.
Why To Use eCATT?
CATT will be no longer supported for the creation of new development. So those using CATT are forced to update to use eCATT. Comparative to manual testing, the following are advantages of using eCATT
Due to automation, testing time is reduced to a large extent.
Due to automation, less manpower is required for testing. This helps financially.
Due to automation, manual errors are reduced to large extent. Hence results in error free testing. This helps, as no further problems will occur while the usage of R/3 system by end users and hence increases the efficiency.
Proved to be extremely useful in Rollout projects
Hope this helps you

Key Configuration differences between SAP and ORACLE Financials

Hello,
After spending good 7 years in SAP related projects recently I started working in ORACLE Applications. I used to be an ORACLE programmer years back. To my surprise the same ORACLE Forms are still very much the heart of the ORACLE UI.
Then I thought what will be the key differences between ORACLE and SAP in terms of configuration elements. While I know a bunch of configuraion items in SAP , I am not sure about the same in ORACLE world. I am not even sure some of the configuration items that are available in SAP exists in ORACLE.
Does anyone know both sides of the coin ? The terminology and design ?
SAP has
Client,Company code, Business area, Functional Area, GL, Posting Key, Document Type.
I am trying to get the details of the equivalents of these in ORACLE.
Does anyone know it ?
For e.g , when you post to AP or AR in SAP , GL is updated automatically. In ORACLE you post to a AP Book or AR Book then Run a batch to move them to GL Book.
ORACLE uses SQLLoader to load data . You can write a PL SQL and update the tables directly, which is not the case in SAP. For dataloads and conversions, SAP uses BDC's ( though XI can be used but its slow).For ORACLE its the good old SQL and PlSQL combo.
What are the equivalents of the configuration elements in ORACLE world ?
Also what are the major differences between these two in terms of designing a financial system.
Does any one know ?

Genie,
I agree that a case is made on how well these two ERPs solve the day to day tasks before a company chooses one of these two. But my question is aimed at finance to begin with. You are going to need a general ledger for any company or government regardless of ERP. And how well you can drive the ledger to map your business is the key here.
The way ledger is built is around a business area ,company or country and is very tighly designed in SAP. I would like to know if there is any equivalent of the configuration items in ORACLE. I am more interested in terminology of ORACLE.
For example ,
SAP ====> ORACLE
GL ==> Book In ORACLE
Document Number ===> Invoice Number
Posting Period in SAP ==> Posting period In ORACLE
Most of the terms are finance terms , so they are common ( eg. an account number is an account number in ORACLE and SAP ) between two systems. I am interested in any specific thing that is available in ORACLE but not in SAP and vice verse.
thanks for the link you have provided.
Its very useful.

Difference between lsmw using BAPI & lsmw using IDOC?

HI everybody
can anybody tell me difference between lsmw using BAPI & lsmw using IDOC?

IDocs and BAPI are very different, so it should be easy to choose between them depending on your requirements.
IDOCS
Advantages
System can work even if target system not always online. The IDoc will be created and sending will just continue once you get connected to the other system.
No additional programming required. You just need to set up the configuration.
Disadvantages
Receipt/processing on the target system may not be immediate.
The sending system has no way to know whether the target system actually received what you sent (unless you use ALE).
If there is no SAP standard IDoc available for your requirement, it's harder to create a customized IDoc than a customized BAPI.
BAPIS
Advantages
You can tell if your sending was successful or not
Sending to/processing on the other side is immediate
Easier to create your own BAPI than your own IDoc
Disadvantages
Will only work if you have an active online connection.
Some programming required to call the BAPI.
Others interface methods you might also want to consider are ALE and RFCs.

Difference Between BADI and User Exits

Hi..
generally BADIs & User Exis are used exensively in SAP SD...
Can anybody throw some light waht is difference between them ...
Kindly please reply......
Regards
Nisha

Hi
ifference Between BADI and User Exits
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
As with customer exits two different views are available:
In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.
In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example).
All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.
The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects.
What is difference between badi and user-exists?
What is difference between enhancements and user-exists? and what is the full form of BADI?
I have another doubt in BDC IN BDC WE HAVE MSEGCALL (i did not remember the > correct name) where the error logs are stored, MSEGCALL is a table or structure.
What is the system landscape?
1) Difference between BADI and USER-EXIT.
    i) BADI's can be used any number of times, where as USER-EXITS can be used only one time.
       Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.
    ii) BADI's are oops based.
2) About 'BDCMSGCOLL' it is a structure. Used for finding error records.
3) Full form of BADI 'Business addins'.
3) System land scape will be depends on your project
    Ex:- 'Development server'>'Quality server'-> 'Production server'......

Difference between standard and actual activity rates

Dear All,
My client is having a process in which while downloading KOB1 the system is giving report of all the process orders wise activities confirmed in that month against some cost center.
Now when i am going into line item it takes me to process order confirmation display where activiies to be confirmed and activities yet to be confirmed are displayed.
After that cost center report S_alr_87013611 is displayed wherein actual rates(quantity ) is displayed for that activities.
Now the system shows difference between actual and standard activities.
The difference is the calculated in excel on the basis of KOB1 report and difference is loaded process order wise on calculation done in excel through LSMW (for transaction KB21n) wherein difference quantity is posted from cost center to process order.
Now client needs automation in the sense that no excel calculation should be done and difference should be posted for that month for each process order in the ratio calculated in excel.
Kindly provide any solutions if any, avaliable in standard or Z development has to be done.
Thanks and Regards,
VLM

Dear AP,
Have you any idea about how in above case Z development is to be done?
Regards,
VLM

Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.
SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to control add-in implementation and make it dependent on specific criteria (on a specific Country value, for example).
All ABAP sources, screens, GUIs, and table interfaces created using this enhancement technique are defined in a manner that allows customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.
The actual program code is enhanced using ABAP Objects. In order to better understand the programming techniques behind the Business Add-In enhancement concept, SAP recommends reading the section on ABAP Objects.
What is difference between badi and user-exists?
What is difference between enhancements and user-exists? and what is the full form of BADI?
I have another doubt in BDC IN BDC WE HAVE MSEGCALL (i did not remember the > correct name) where the error logs are stored, MSEGCALL is a table or structure.
What is the system landscape?
1) Difference between BADI and USER-EXIT.
    i) BADI's can be used any number of times, where as USER-EXITS can be used only one time.
       Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.
    ii) BADI's are oops based.
2) About 'BDCMSGCOLL' it is a structure. Used for finding error records.
3) Full form of BADI 'Business addins'.
3) System land scape will be depends on your project
    Ex:- 'Development server'>'Quality server'-> 'Production server'......

Difference between Null and null?

What is the difference between null and NULL?
When is each used?
Thanks,

There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. Null means, the referential type is not assigned (doesn't refer) to a specific object. The empty String is just another object though, so seeing it or pointing it out as something special when it actually isn't at all (no more special than new Integer(0) or new Object[0]) just adds to the confusion.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename
              filetype                = 'ASC'
         changing
              data_tab                = iflatf
         exceptions
              file_open_error         = 1
              file_read_error         = 2
              no_batch                = 3
              gui_refuse_filetransfer = 4
              no_authority            = 6
              unknown_error           = 7
              bad_data_format         = 8
              unknown_dp_error        = 12
              access_denied           = 13
              others                  = 17.
