Grantor Objects Migration from Legacy System

Hi All,
I have a scenario in which I will be requried to migrate Grantor objects (Programs, Application, Claim, Change Request, billing documents) from legacy system.
I checked the busines objects for Application but could not find the Create Method as we have for Sales Order or Activities.
Can we migrate these objects from Legacy System using lsmw or BAPI's?
Thanks in advance.

Data migration from legacy system to SAP

hi all,
could you please post some docs on migration from legacy system to SAP system., also the problems faced while migration and best practices in data migration
regards
sridharan

Hi ,
I require few details from you.
1. What ETL tool you are using, If Informatica, it already have PowerConnect to connect to SAP. So you can create source and Target Structure and also you can use RFC's to send data to R/3. Else, for other ETL tools, can you prepare RFC's or any other way to send data to R/3. let me know the tool.
2. Does R/3 contains the master data tables? If yes, then try to use LSMW for Mass upload of data to tables.
If your client don't want to use either of these options please elaborate, what is the case.

How to UNLOCK queues when data is migrated from legacy system to SAP syste

Hi All,
I need some help regarding queues (SMQ2). XI is been used to migrate data from legacy system to SAP system. Sometimes the queue is getting locked. Once the queue is unlocked then the message is processed correctly. So, the incoming queues must be "unlocked" routinely so that they can process through the system. There is a standard report RSQIWKEX available that can be scheduled in SAP system to automatically unlock the queues. Before using the standard report RSDIWKEX, we made sure that we have added parameter MONITOR QRFC_RESTART_ALLOWED set to "1" in Integration Engine specific configuration (TCODE SXMB_ADM).We are unable to analyze the reason for locking of queues and how to avoid it. If the locking of the queues can not be avoided, is there any way to unlock the queues? We tried executing this report but were not successful in unlocking the queues. Please guide us in solving this issue. It would be really helpful if you can give us a direction in solving this problem.
Thanks in Advance,
Shwetha.

Hi,
Just check if the Queues are registered in Transaction SMQR.
If its not, then register the Queue by pressing 'Register' Button

Data Migration from Legacy system to ECC systems via ETL through SAP PI

Hi All,
I wanted to know if we can migrate the data from Legacy systems to ECC systems via PI.
What I understand is there is ETL tool is used to extract the data from legacy system, and what client is looking to load that data via PI?
Can we do that ? I am concerned because this will involve mass data?
If I have to use PI , I see option of PROXY / IDOC /FILE as receiver in ECC system (take the data from ETL)?
Can somebody has done this earlier , please share the approach.
Thanks,

Hello,
for migration into CRM I would suggest the 'XIF-Interfaces'; these are interfaces provided in CRM for connection to external systems. I'm not sure if this will cover all objects mentioned above, but at least some of them should exist.
Some information about existing interfaces can be found in the integration repository under http://ifr.sap.com/index.html; from the start screen first select 'Enter the repository' and then have a look under 'generic components' and 'SAP CRM'.

Hi Ram,
Use Transaction Code EMIGALL. It will ask for company code. By default Company Code is SAP. If you entered with the SAP you will get all the objects.Then goto menu IS-U Migration-->User Handbook. It will give you details Idea.
Also Check the following Procedure
You can find detailed documentation of EMIGALL in SAP itself. Use Transaction EQ81 to display it. It provides all the concepts and procedures to work with EMIGALL.
Here are some points about EMIGALL :
1. It Migrates data Business Object wise
2. It uses Direct Input Technique
3. It has more than 100 objects of IS-U
and the steps for implementation goes like this:
1)You have to create a user specially for migration which will have all the authorizations related to migration workbench, BASIS and IS-U
2)You have to create your own company in EMIGALL. There is a default company called SAP.
3)Company SAP contains all the Business Objects
4)You have to figure out what business objects u need and then u have to copy those business objects to ur company from Standard Company SAP
5)Each objects contains more than one structure and each structure can contain more than one fields. The relation goes like this
Object ---> Structure ---> Field
6)You have to define field rules for each required field of the object. You have to mark "Not required" for fields u don't need
7)After field rules for a given object is set u have to generate load report i.e. actual Direct Input Program which will migrate data. This program is generated on basis of field rules set by u.
8)After the load report is generated u have to prepare an input file (import File) for migration. The import file should be according to structure provided by SAP and must be in binary format. SAP Provides the structure of file according to your configurations. You have to write ur own Data conversion program(in any language) for this task.
9)You take import file as input and migrate the data using generated load program
10)Finally u can check the Migration Statistics and Error Log

Date migration from Legacy system (excel file) to CRM 7.0

Hi,
Can any one guide me on the below:
I am provided with excel files having prospect data with 63 fields and most of them are not the part of standard fields available.
The requirement is to create the same data in CRM. I am unable to use ELM as most of the fields are not available. I suppose i need to get the fields created by technical team. However need some knowledge sharing on this. I think even BAPI approach would need fields to be created first.
Should i revert back to the client asking for detailed information on the tabs or sections under which the missing fileds have to be created?
Also guide me with alternate solution to map the data from legacy to CRM
Please mark your solution on this
thanks

Agarwal,
In your situation you need to have the additional attributes created in CRM, before you can do an upload. Now if the new attributes are marketing attributes for the business partner, you can use ELM. Otherwise if you still want to do ELM then you need to use the BADI.
Your other option is use XIF adapter with LSMW to perform the upload, but the custom fields must appear in the bdoc structure on the CRM for them to appear. Normally this won't be a problem if the CRM system has been extended via EEWB or AET.
Take care,
Stephen

hi jyothi ,
   there are lot of ways of doing it depending on data upload volume it will be decided .
1) thru abap bdc program which directly uses XL sheet data and creates SO using bapi/FMs.
2) using scat.functional consultant should be good enough to use this.
3)lsmw-laborious procedure but achievable.
reward if helps !!!!!

Uploading data from Legacy system

Hi
i am shorthly going to work on data migration project. I have never worked on a data migration project and want to know the answers for the following questions.
1] which technique i must first consider in data upload ( both master data and transaction data )
2] What steps are involved?
3] I know we can use LSMW, BAPI's , BDC , Direct Input , IDOC etc but want to know which one choose and when?
4] What care must be taken in each data migration
5] is there is std list of programs or a good document on when to choose what?
~SR

Hi,
Data migration can be done by the follwoing methods:
LSMW : for master data migartion or small data migartion
BAPI : its just like a FM , thru which u can create master aswell as Transactional data.
u have to import some paremetre as well as tables if required, and Bapi will RETURN the message saying so and so material/delievry had cretaed.
BDC : in BDC we got 2 methods.
CAll transaction and session.
CAll transacton : using this u can uplaod transcational data as well as master data.
the updation can be synchronus or asynchronus updates.
Session: using this u can uplaod transcational data as well as master data.
The updation in session is synchronus, so its time taking process.
Most of the time we go for Call transcation In real situations.
Dircet input method: its out dated.no longer it is being used.
in all the above cases, data is alraedy existing in flat file and u r going to migrate the data in one shot but IDOC is used where the dynamical data migration is necessary.
suppose say ones the material is craeted in legacy sytem , that particulat matreial shud be migarted to R/3.this can be handled thru IDOC.
Idoc: master data as well as Trnascational data is migarted thru IDOC( matmas, orders).
Idoc uses ALE technology in migartion of idoc.
Revert back if any issues.
Check these links.

LSMW
No ABAP effort are required for the SAP data migration. However, effort are required to map the data into the structure according to the pre-determined format as specified by the pre-written ABAP upload program of the LSMW.
The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data once only or periodically from legacy systems into an R/3 System.
More and more medium-sized firms are implementing SAP solutions, and many of them have their legacy data in desktop programs. In this case, the data is exported in a format that can be read by PC spreadsheet systems. As a result, the data transfer is mere child's play: Simply enter the field names in the first line of the table, and the LSM Workbench's import routine automatically generates the input file for your conversion program.
The LSM Workbench lets you check the data for migration against the current settings of your customizing. The check is performed after the data migration, but before the update in your database.
So although it was designed for uploading of legacy data it is not restricted to this use.
We use it for mass changes, i.e. uploading new/replacement data and it is great, but there are limits on its functionality, depending on the complexity of the transaction you are trying to replicate.
The SAP transaction code is 'LSMW' for SAP version 4.6x.
For those with the older SAP version (4.7 and below), the data migration programs might not have been pre-loaded.
You can download the LSMW at no cost from SAPNet under Services, SAP Methodology and Tools, category Tools.
If you are an existing SAP customer with an OSS ID, you can access the SAP Service Marketplace to download the LSWM for your Basis teams to install to your SAP system: http://service.sap.com/lsmw
The LSM Workbench carries out the following tasks:
Reads the transfer data from one or more files (for example, spreadsheets, sequential files etc.)
Converts the data from the source format into the target format
Note that with background processing, the input file must not be located in the presentation server. Access to presentation server files is only possible when you are working onlineUpload Condition Pricing
LSMW STEPS
Data Cleansing
Data cleansing allows you to compare, include and merge redundant business partner master records (potential duplicates) in data cleansing cases. Following the data cleansing process you can remove data records from the system using archiving.
Integration
Before you can carry out data cleansing, you must determine the redundant data in your system and include it in data cleansing cases.
You have the following options for duplicate recognition and creation of data cleansing cases.
The Business Address Services (BAS) provide interfaces for integrating the relevant external software (search machines).
User-defined programs
Services of data providers, who check their data for possible duplicates.
In the options described above, the data cleansing cases are created via the system and put into the data cleansing worklist for further processing.
In individual cases you can find potential business partner duplicates in the hitlist of the business partner search and create a separate data cleansing case.
After connecting the non-SAP software (search engines), the system starts duplicate recognition (Delta Scan) with every change to or new entry of a business partner for this specific individual record. You should do a full scan through the complete dataset at the beginning of the consolidation process using the non-SAP software, this registers all potential duplicates in data cleansing cases and makes them available or further processing.
Within the application basis, the referencing objects, which are taken into account by the data cleansing, are limited to the sub-objects of the business partner. You have the possibility to make modification-free enhancements to the referencing objects.
Prerequisites
You must have determined the redundant data records in your system.
To use the interface of the Business Address Services, make the following Customizing settings: SAP Implementation Guide -> Basis -> Basis Services -> Address Management -> Activate Duplicate Check Index Pool
Make the following system settings in the IMG of the SAP Business Partner: Basic Settings -> Data Cleansing -> Maintain Number Range / Define Priorities / Activate Data Cleansing.
Activities
Register data cleansing cases via BAPIs or create them in the dialog for business partner maintenance from the worklist or the business partner search.
Process the created data cleansing cases in a separate process step afterwards.
BATCH DATA COMMUNICATION
About Data Transfer In R/3 System
When a company decides to implement the SAP R/3 to manage business-critical data, it usually does not start from a no-data situation. Normally, a SAP R/3 project comes into replace or complement existing application.
In the process of replacing current applications and transferring application data, two situations might occur:
The first is when application data to be replaced is transferred at once, and only once.
The second situation is to transfer data periodically from external systems to SAP and vice versa.
There is a period of time when information has to be transferred from existing application, to SAP R/3, and often this process will be repetitive.
The SAP system offers two primary methods for transferring data into SAP systems. From non-SAP systems or legacy system. These two methods are collectively called batch input or batch data communication.
1. SESSION METHOD
2. CALL TRANSACTION
3. DIRECT INPUT
Advantages offered by BATCH INPUT method:
1. Can process large data volumes in batch.
2. Can be planned and submitted in the background.
3. No manual interaction is required when data is transferred.
4. Data integrity is maintained as whatever data is transferred to the table is through transaction. Hence batch input data is submitted to all the checks and validations.
To implement one of the supported data transfers, you must often write the program that exports the data from your non-SAP system. This program, known as a data transfer program must map the data from the external system into the data structure required by the SAP batch input program.
The batch input program must build all of the input to execute the SAP transaction.
Two main steps are required:
To build an internal table containing every screen and every field to be filled in during the execution of an SAP transaction.
To pass the table to SAP for processing.
Prerequisite for Data Transfer Program
Writing a Data Transfer Program involves following prerequisites:
Analyzing data from local file
Analyzing transaction
Analyzing transaction involves following steps:
The transaction code, if you do not already know it.
Which fields require input i.e., mandatory.
Which fields can you allow to default to standard values.
The names, types, and lengths of the fields that are used by a transaction.
Screen number and Name of module pool program behind a particular transaction.
To analyze a transaction::
Start the transaction by menu or by entering the transaction code in the command box.
(You can determine the transaction name by choosing System Status.)
Step through the transaction, entering the data will be required for processing your batch input data.
On each screen, note the program name and screen (dynpro) number.
(dynpro = dyn + pro. Dyn = screen, pro = number)
Display these by choosing System Status. The relevant fields are Program (dynpro) and Dynpro number. If pop-up windows occur during execution, you can get the program name and screen number by pressing F1 on any field or button on the screen.
The technical info pop-up shows not only the field information but also the program and screen.
For each field, check box, and radio button on each screen, press F1 (help) and then choose Technical Info.
Note the following information:
- The field name for batch input, which youll find in its own box.
The length and data type of the field. You can display this information by double clicking on the Data Element field.
Find out the identification code for each function (button or menu) that you must execute to process the batch-input data (or to go to new screen).
Place the cursor on the button or menu entry while holding down the left mouse button. Then press F1.
In the pop-up window that follows, choose Technical info and note the code that is shown in the Function field.
You can also run any function that is assigned to a function key by way of the function key number. To display the list of available function keys, click on the right mouse button. Note the key number that is assigned to the functions you want to run.
Once you have program name, screen number, field name (screen field name), you can start writing.
DATA TRANSFER program.
Declaring internal table
First Integral Table similar to structure like local file.
Declaring internal table like BDCDATA
The data from internal table is not transferred directly to database table, it has to go through transaction. You need to pass data to particular screen and to particular screen-field. Data is passed to transaction in particular format, hence there is a need for batch input structure.
The batch input structure stores the data that is to be entered into SAP system and the actions that are necessary to process the data. The batch input structure is used by all of the batch input methods. You can use the same structure for all types of batch input, regardless of whether you are creating a session in the batch input queue or using CALL TRANSACTION.
This structure is BDCDATA, which can contain the batch input data for only a single run of a transaction. The typical processing loop in a program is as follows:
Create a BDCDATA structure
Write the structure out to a session or process it with CALL TRANSACTION USING; and then
Create a BDCDATA structure for the next transaction that is to be processed.
Within a BDCDATA structure, organize the data of screens in a transaction. Each screen that is processed in the course of a transaction must be identified with a BDCDATA record. This record uses the Program, Dynpro, and Dynbegin fields of the structure.
The screen identifier record is followed by a separate BDCDATA record for each value, to be entered into a field. These records use the FNAM and FVAL fields of the BDCDATA structure. Values to be entered in a field can be any of the following:
Data that is entered into screen fields.
Function codes that are entered into the command field. Such function codes execute functions in a transaction, such as Save or Enter.
The BDCDATA structure contains the following fields:
PROGRAM: Name of module pool program associated with the screen. Set this field only for the first record for the screen.
DYNPRO: Screen Number. Set this field only in the first record for the screen.
DYNBEGIN: Indicates the first record for the screen. Set this field to X, only for the first record for the screen. (Reset to (blank) for all other records.)
FNAM: Field Name. The FNAM field is not case-sensitive.
FVAL: Value for the field named in FNAM. The FVAL field is case-sensitive. Values assigned to this field are always padded on the right, if they are less than 132 characters. Values must be in character format.
Transferring data from local file to internal table
Data is uploaded to internal table by UPLOAD of WS_UPLOAD function.
Population of BDCDATA
For each record of internal table, you need to populate Internal table, which is similar to BDCDATA structure.
All these five initial steps are necessary for any type of BDC interface.
DATA TRANSFER program can call SESSION METHOD or CALL TRANSACTION. The initial steps for both the methods are same.
First step for both the methods is to upload the data to internal table. From Internal Table, the data is transferred to database table by two ways i.e., Session method and Call transaction.
SESSION METHOD
About Session method
In this method you transfer data from internal table to database table through sessions.
In this method, an ABAP/4 program reads the external data that is to be entered in the SAP System and stores the data in session. A session stores the actions that are required to enter your data using normal SAP transaction i.e., Data is transferred to session which in turn transfers data to database table.
Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.
When the program has finished generating the session, you can run the session to execute the SAP transactions in it. You can either explicitly start and monitor a session or have the session run in the background processing system.
Unless session is processed, the data is not transferred to database table.
BDC_OPEN_GROUP
You create the session through program by BDC_OPEN_GROUP function.
Parameters to this function are:
User Name: User name
Group: Name of the session
Lock Date: The date on which you want to process the session.
Keep: This parameter is passed as X when you want to retain session after
processing it or to delete it after processing.
BDC_INSERT
This function creates the session & data is transferred to Session.
Parameters to this function are:
Tcode: Transaction Name
Dynprotab: BDC Data
BDC_CLOSE_GROUP
This function closes the BDC Group. No Parameters.
Some additional information for session processing
When the session is generated using the KEEP option within the BDC_OPEN_GROUP, the system always keeps the sessions in the queue, whether it has been processed successfully or not.
However, if the session is processed, you have to delete it manually. When session processing is completed successfully while KEEP option was not set, it will be removed automatically from the session queue. Log is not removed for that session.
If the batch-input session is terminated with errors, then it appears in the list of INCORRECT session and it can be processed again. To correct incorrect session, you can analyze the session. The Analysis function allows to determine which screen and value has produced the error. If you find small errors in data, you can correct them interactively, otherwise you need to modify batch input program, which has generated the session or many times even the data file.
CALL TRANSACTION
About CALL TRANSACTION
A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program by
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>
Messages into <MSGTAB>.
Parameter 1 is transaction code.
Parameter 2 is name of BDCTAB table.
Parameter 3 here you are specifying mode in which you execute transaction
A is all screen mode. All the screen of transaction are displayed.
N is no screen mode. No screen is displayed when you execute the transaction.
E is error screen. Only those screens are displayed wherein you have error record.
Parameter 4 here you are specifying update type by which database table is updated.
S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.
A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).
Parameter 5 when you update database table, operation is either successful or unsuccessful or operation is successful with some warning. These messages are stored in internal table, which you specify along with MESSAGE statement. This internal table should be declared like BDCMSGCOLL, a structure available in ABAP/4. It contains the following fields:
1. Tcode: Transaction code
2. Dyname: Batch point module name
3. Dynumb: Batch input Dyn number
4. Msgtyp: Batch input message type (A/E/W/I/S)
5. Msgspra: Batch input Lang, id of message
6. Msgid: Message id
7. MsgvN: Message variables (N = 1 - 4)
For each entry, which is updated in database, table message is available in BDCMSGCOLL. As BDCMSGCOLL is structure, you need to declare a internal table which can contain multiple records (unlike structure).
Steps for CALL TRANSACTION method
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. UPLOAD or WS_UPLOAD function to upload the data from local file to itab. (Considering file is local file)
4. Loop at itab.
Populate BDCTAB table.
Call transaction <tcode> using <BDCTAB>
Mode <A/N/E>
Update <S/A>.
Refresh BDCTAB.
Endloop.
(To populate BDCTAB, You need to transfer each and every field)
The major differences between Session method and Call transaction are as follows:
SESSION METHOD CALL TRANSACTION
1. Data is not updated in database table unless Session is processed. Immediate updation in database table.
2. No sy-subrc is returned. Sy-subrc is returned.
3. Error log is created for error records. Errors need to be handled explicitly
4. Updation in database table is always synchronous Updation in database table can be synchronous Or Asynchronous.
Error Handling in CALL TRANSACTION
When Session Method updates the records in database table, error records are stored in the log file. In Call transaction there is no such log file available and error record is lost unless handled. Usually you need to give report of all the error records i.e., records which are not inserted or updated in the database table. This can be done by the following method:
Steps for the error handling in CALL TRANSACTION
1. Internal table for the data (structure similar to your local file)
2. BDCTAB like BDCDATA
3. Internal table BDCMSG like BDCMSGCOLL
4. Internal table similar to Ist internal table
(Third and fourth steps are for error handling)
5. UPLOAD or WS_UPLOAD function to upload the data from the local file to itab. (Considering file is local file)
6. Loop at itab.
Populate BDCTAB table.
Call transaction <tr.code> using <Bdctab>
Mode <A/N/E>
Update <S/A>
Messages <BDCMSG>.
Perform check.
Refresh BDCTAB.
Endloop.
7 Form check.
IF sy-subrc 0. (Call transaction returns the sy-subrc if updating is not successful).
Call function Format_message.
(This function is called to store the message given by system and to display it along with record)
Append itab2.
Display the record and message.
DIRECT INPUT
About Direct Input
In contrast to batch input, this technique does not create sessions, but stores the data directly. It does not simulate the online transaction. To enter the data into the corresponding database tables directly, the system calls a number of function modules that execute any necessary checks. In case of errors, the direct input technique provides a restart mechanism. However, to be able to activate the restart mechanism, direct input programs must be executed in the background only. Direct input checks the data thoroughly and then updates the database directly.
You can start a Direct Input program in two ways;
Start the program directly
This is the quickest way to see if the program works with your flat file. This option is possible with all direct input programs. If the program ends abnormally, you will not have any logs telling you what has or has not been posted. To minimize the chance of this happening, always use the check file option for the first run with your flat file. This allows you to detect format errors before transfer.
Starting the program via the DI administration transaction
This transaction restarts the processing, if the data transfer program aborts. Since DI document are immediately posted into the SAP D/B, the restart option prevents the duplicate document posting that occurs during a program restart (i.e., without adjusting your flat file).
Direct input is usually done for standard data like material master, FI accounting document, SD sales order and Classification for which SAP has provided standard programs.
First time you work with the Direct Input administration program, you will need to do some preparation before you can transfer data:
- Create variant
Define job
Start job
Restart job
Common batch input errors
- The batch input BDCDATA structure tries to assign values to fields which do not exist in the current transaction screen.
The screen in the BDCDATA structure does not match the right sequence, or an intermediate screen is missing.
On exceptional occasions, the logic flow of batch input session does not exactly match that of manual online processing. Testing the sessions online can discover by this.
The BDCDATA structure contains fields, which are longer than the actual definition.
Authorization problems.
RECORDING A BATCH INPUT
A B recording allows you to record a R/3 transaction and generate a program that contains all screens and field information in the required BDC-DATA format.
You can either use SHDB transaction for recording or
EDIT BATCH INPUT  SERVICES SYSTEM
And from here click recording.
Enter name for the recording.
(Dates are optional)
Click recording.
Enter transaction code.
Enter.
Click Save button.
You finally come to a screen where, you have all the information for each screen including BDC_OKCODE.
Click Get Transaction.
Return to BI.
Click overview.
Position the cursor on the just recorded entry and click generate program.
Enter program name.
Click enter
The program is generated for the particular transaction.
BACKGROUND PROCESSING
Need for Background processing
When a large volume of data is involved, usually all batch inputs are done in background.
The R/3 system includes functions that allow users to work non-interactively or offline. The background processing systems handle these functions.
Non-interactively means that instead of executing the ABAP/4 programs and waiting for an answer, user can submit those programs for execution at a more convenient planned time.
There are several reasons to submit programs for background execution.
The maximum time allowed for online execution should not exceed 300 seconds. User gets TIMEOUT error and an aborted transaction, if time for execution exceeds 300 seconds. To avoid these types of error, you can submit jobs for background processing.
You can use the system while your program is executing.
This does not mean that interactive or online work is not useful. Both type of processing have their own purposes. Online work is the most common one entering business data, displaying information, printing small reports, managing the system and so on. Background jobs are mainly used for the following tasks; to process large amount of data, to execute periodic jobs without human intervention, to run program at a more convenient, planned time other than during normal working hours i.e., Nights or weekends.
The transaction for background processing is SM36.
Or
Define jobs Jobs  Administration Tools
Or
System Jobsservices
Components of the background jobs
A job in Background processing is a series of steps that can be scheduled and step is a program for background processing.
Job name. Define the name of assigned to the job. It identifies the job. You can specify up to 32 characters for the name.
Job class. Indicates the type of background processing priority assigned to the job.
The job class determines the priority of a job. The background system admits three types of job classes: A B & C, which correspond to job priority.
Job steps. Parameters to be passed for this screen are as follows:
Program name.
Variant if it is report program
Start criteria for the job: Option available for this are as follows:
Immediate - allows you to start a job immediately.
Date/Time - allows you to start a job at a specific name.
After job - you can start a job after a particular job.
After event - allows you to start a job after a particular event.
At operation mode - allows you to start a job when the system switches to a particular operation mode.
Defining Background jobs
It is two step process: Firstly, you define the job and then release it.
When users define a job and save it, they are actually scheduling the report i.e., specifying the job components, the steps, the start time.
When users schedule program for background processing, they are instructing the system to execute an ABAP/4 report or an external program in the background. Scheduled jobs are not executed until they are released. When jobs are released, they are sent for execution to the background processing system at the specified start time. Both scheduling and releasing of jobs require authorizations.
HANDLING OF POP UP SCREEN IN BDC
Many times in transaction pop up screen appears and for this screen you dont pass any record but some indication to system telling it to proceed further. For example: The following screen
To handle such screen, system has provided a variable called BDC_CURSOR. You pass this variable to BDCDATA and process the screen.
Usually such screen appears in many transactions, in this case you are just passing information, that YES you want to save the information, that means YES should be clicked. So you are transferring this information to BDCDATA i.e., field name of YES which is usually SPOT_OPTION. Instead of BDC_OKCODE, you are passing BDC_CURSOR.
BDC_CURSOR is also used to place cursor on particular field.
AN EXAMPLE WITH SESSION METHOD
Following program demonstrates how data is passed from flat file to SAP transaction and further to database table by using SESSION method.
The transaction is TFBA (to change customer).
A simple transaction where you are entering customer number on first screen and on next screen data is displayed for the particular customer number. Field, which we are changing here, are name and city. When you click on save, the changed record gets saved.
Prerequisite to write this BDC interface as indicated earlier is:
1. To find screen number
2. To find screen field names, type of the field and length of the field.
3. To find BDC_OKCODE for each screen
4. Create flat file.
Flat file can be created in your hard disk as follows:
1 Vinod Krishna Hyderabad
2 Kavitha Secunderabad
3 Kishore Hyderabad
(Where 1st character field is Customer number, 2nd field is Customer name and 3rd field is City.)
To transfer this data to database table SCUSTOM following interface can be used.
REPORT DEMO1.
Following internal table is to upload flat file.
DATA: BEGIN OF ITAB OCCURS 0,

IDOC
What is IDOC ?
IDoc
Standard SAP format for electronic data interchange between systems (Intermediate Document). Different message types (such as delivery confirmations or purchase orders) normally represent different specific formats, the IDoc types. However, multiple message types with related content can be assigned to one IDoc type: For example, the IDoc type ORDERS01 transfers the logical message types ORDERS (purchase order) and ORDRSP (order confirmation).

How to upload the data from legacy system database to SAP data base

Hi.
We are doing analysis of Legacy system and which needs to be converted to SAP system i.e. SAP implementation.
I just want to know , how we migrate the existing whole data( from legacy system) into SAP system.
and which method is the best method to use data migration from legacy to SAP system if data legacy data amount is huge.
Please suggest me.
Thanks.

Hi
We can either use the BDC or BAPI or LSMW or Direct Input techiniques for the data transfers.
The combination of both Session and Call transaction can be used to achieve this that includes the error handling also. This invloves the screen interaction.
These days, BAPIs are used to overvome some upgrade problems. For easy upgradation, we cna go for BAPIs. Here ther is no screen intercation.
LSMW mainly used for master data transfers using some standrad programs.
As per your client or company desicions we can choose any of them.
Please refer to these links for more understanding -
