Data Migration Basics

Hi Group,
Could anybody just explain me the basic conditions for IDOCs and BAPIs for data transfer.... What i know we can use IDOCs in a distributed R/3 system... If we are transfering data from a non-sap(in case of LSMW) system then we cant use an IDOC. And what about BAPI... Can we use it for the above case.. i.e from non-sap to sap.
What are the pre-conditions for IDOCs and BAPIs to choose for a data transfer???
Thanks.

Samir
Regarding IDOC's u r absolutly correct
where as for BAPI's
BAPIs are normally called synchronously in order to get feedback immediately.A synchronous call will only work if the system we want to access is up and running.For some purposes like data transfer, SAP wanted BAPIs to invoke asynchronously so that the calling application could proceed even if the remote system was currently unavailable.
Hence these BAPIs are linked to ALE (Application Linking and Enabling),an asynchronous message passing mechanism with guaranteed delivery.ALE uses Idocs as the containers for messages. Idocs are instances of Idocs types, which in turn are associated ALE message types.
SAP has provided a generator which takes a BAPI and generates an appropriate ALE message type and an associated Idoc type.
For our data transfer purposes using LSMW, we can use only those BAPIs which are linked to the ALE message types.
I think i cleared ur point....

Data Migration of FI-CA Cleared Items

Hi,
Currently I am working on a Data Migration project to migrate data from our FI-CA module on ERP 4.7 to ECC 6.0.
THere has been a request from the business to migrate historical data (e.g. Cleared items).
Is there a SAP recommended approach or tools to load this data into the target environment?
Currently all documentation around SAP data migrations talks about stategies for open item data migration however I have seen nothing arouund migrating historical financial data.
Is this because it is not recommended or technically impossible?
Regards
Adam Gunn

That BAPI is used typically for straight out vanilla GL, AR, AP postings, however you still have to create the other side of the entry and then clear it.
I need to be able to migrate full history, which means from an FI-CA viewpoint:
1. Migrate FI-CA posting of liability against BP/contract account.
2. Migrate associated payments.
3. And then clearing documents.
Basically the requirement is to represent the historical data in the new system as if it was posted and matched off.
Is there a technical way to do this?
OR,
Do you migrate the FI-CA liabilties, then the associated payments and then run clearing on the target system?
I suspect this is almost an impossible data migration requirement as development of the extraction and load process would be extremely complex and testing would take months to cover all posting scenarios in FI-CA. However, I would be interested if anyone has attempted to do this before.

Transaction Data Migration

Is there a "best practice" for transaction data conversions from a legacy system into R/3? I am in a project where I have to create a strategy for SCM transaction data (PO's, Inventory, Vendor Invoices, and so on). I would like to know the pros and cons of migrating a PO in their various stages (Open, G/R but not yet invoiced, Partial G/R). Basically a strategy to propose to my client regarding their SCM transaction data.
Thanks for your help!!!!

hi,
For uploading the GLs :-->
Use FB50 entry Dr GL a/c Credit Data migration a/c or controlling a/c
For uploading the Vendor balances : -->
Use FB60 entry Dr Data migration a/c or controlling a/c and credit Vendor a/c (individually)
For uploading the Customers balances :-->
Use FB70 entry Dr Customers a/c (individually) Cr Data migration a/c or controlling a/c
For uploading the Assets-->
AS91 -> for uploading assets in AA
OSAV --> for uploading assets in GL entry Dr Asset (invidiually) Cr Data Migration account or controlling account
You can use LSMW for uploading all these things
After uploading all, your data migration account will become zero.
For posting the transactional data use LSMW for relevant TCODES

RollOut: Data migration phase - material master

Dear all,
we are going to implement the SAP in one of our subsidiaries. The phase data migration of the material master is not that clear because I am not very experienced in such a project.
Can anybody consult me concerning my intentions?
I would like to subdivide the prozess data migration in the following separate steps:
1. Analysis of the structure and the material master fields of the legacy system
First I would require an example structure of the legacy system to get a first overview. This structure should be an excel sheet. Then I would discuss this structure with the staff of our subsidiary.
2. Structure of our SAP system
The structure of the SAP and all the necessary fields of the material master will be discussed with the staff of the subsidiary.
3. Comparing of both structures
Compare both structures and define which fields are missing and which fields have to be added
4. Preparation of the migration tool (LSMW)
I would be very grateful to get a reply or critic are recommendations.
Did I forget anything?
Thank you very much
Conan

I think you basically got what needs to be done.
I usually let the module teams deliver the SAP fields that are necessary for their process.
For the source data I contact the team that deals with the legacy system.
Then we map fields and find the source fields that have to target, as well as mandatory target fields that have no source data.
And I request this usually per material type, as each material type may have different requirements.
Start with the process as early as possible, best with project begin already.
I am currently doing a huge migration project (merging of several SAP systems) , started last December, and I still miss a lot of mappings.
I made the exerience that I get mapping for the well kown entries of a field, however, there are many records that have different values, maybe values that should not be used anymore in the legacy system, but old records never go adjusted, hence I have them as error when loading.

Data migration ALE or idocs and bapis

hi ,
thank you guys for the support.
i am into a data migration project.
i need the initial setup for the idocs and bapis.
i dont know anything about these so can u send me the process for the setup and the data migration process too with idocs and bapis.
i didnt understand when they asked me if we can data migrate with a ALE, is that the same as using idocs and bapis or is it a different approach.
u can send me at any inofrmation connected to my eamil addr.
i would really appreciate that.
thank you.

Bdc to Bapi
The steps to be followed are :
1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
for VA01 use BAPI_SALESORDER_CREATEFROMDAT2
2. Create a Z program and call the BAPi (same as a Funtion module call).
2. Now, if you see this BAPi, it has
-> Importing structures.
eg: SALESDOCUMENT: this will take the Sales order header data as input.
-> Tables parameters:
eg: ORDER_ITEM_IN: this will take the line item data as input.
Note :
Only specify fields that should be changed
Select these fields by entering an X in the checkboxes
Enter a U in the UPDATEFLAG field
Always specify key fields when changing the data, including in the checkboxes
The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
Maintain quantities and dates in the schedule line data
Possible UPDATEFLAGS:
U = change
D = delete
I = add
Example
1. Delete the whole order
2. Delete order items
3. Change the order
4. Change the configuration
Notes
1. Minimum entry:
You must enter the order number in the SALESDOCUMENT structure.
You must always enter key fields for changes.
You must always specify the update indicator in the ORDER_HEADER_INX.
2. Commit control:
The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
For further details... refer to the Function Module documentation for the BAPi.
Bapi to VB(Visual Basic)
Long back I had used the following flow structure to acheive the same.
Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
You need to have com4abap.exe
If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.
else refer OSS note 419822 for installation of com4abap
after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
for setting up com4abap and rfc destination please refer to the documentation for com4abap.
Invoke NEW DCOM session
call function 'BEGIN_COM_SESSION'

Validation rules applied to data migration templates at import

Hi everyone!
First post here for me, so please bear with me if I missed something.
My company has just started the initial implementation of ByDesign. We come from a set of disparate and partially home-grown systems that we outgrew a few years ago.
As part of this initial phase, we are basically re-creating the data on customers, suppliers, etc. since none of our existing systems makes a good source, unfortunately. We will be using the XML templates provided by ByDesign itself to import the relevant data.
It has become clear that ByDesign applies validation rules on fields like postal codes (zip codes), states (for some countries), and other fields.
It would be really helpful if we could get access to the rules that are applied at import time, so that we can format the data correctly in advance, rather than having to play "trial and error" at import time. For example, if you import address data, the first time it finds a postal code in the Netherlands which is formatted as "1234AB", it will tell you that "there needs to a space in the 5th position, because it expects the format to be "1234 AB". At that point, you stop the import, go back to the template to fix all the Dutch postal codes, and try the import again, only to run into the next validation issue.
We work with a couple of very experienced German consultants to help us implement ByDesign, and I have put this question to them, but they are unaware of a documented set of validation rules for ByDesign. Which is why I ask the question here.
So just to be very celar on what we are looking for: the data validation/formatting rules that ByDesign enforces at the time the XML data migration templates are imported.
Any help would be appreciated!
Best regards,
Eelco

Hello Eelco,
welcome to the SAP ByDesign Community Network!
The checks performed on postal codes are country specific, and represent pretty much the information that you would find in places like e.g. the "Postal Codes" page in Wikipedia.
I recommend to start with small files of 50-100 records that are assembled of a representative set of different records, in order to collect the validation rules that need reactions based on your data in an efficient way. Only once you have caught these generic data issues, I would proceed to larger files.
Personnaly I prefer to capture such generic work items on my list, then fix the small sample file immediately by editing, and do an immediate resimulation of the entire file, so that I can drill deeper and collect more generic issues of my data sample. Only after a while when I have harvested all learnings that were in my sample file, I would then apply the collected learnings to my actual data and create a new file - still not too large, in order to use my time efficiently.
Best regards
Michael

How to use IDoc. in data migration?

Dear Expert,
How can I use IDoc. method in Data Migration???

Hi,
You can use Idoc method in data migration using LSMW - Idoc method.
In LSMW select the Idoc method and give the Message type and Basic type according to your requirement.
Before that you need to maintain the Idoc inbound processing.
Goto LSMW initial screen,
LSMW -> Settings -> IDoc Inbound Processing. Maintain File port, partner type and partner no.
After maintaining the Partner no. goto WE20 (maintain partner no.) and add the message type in the Inbound parameters of the partner no. Also we need to maintain the Process code for the message type.
After all this settings we can use Idoc method for data migration.
The rest of the steps are same as other methods till convert data.

Asif Ali Khan

Data migration tools in sap

hi,
i am newbie to s.a.p nd i got ma project related to data migration. we are taking data from legacy system to sap database. we are using a tool called cransoft. what about the future of this tool. how to plan my career in this data migration.need help from experienced persons. im a sap abap resource actually. im having practically no work using abap in this project.im very much concerned about ma career.help me out...
thank you

>>will my career depend on the tool im working in or it depends on data migration only
That is something which depends upon how much and what kind of experience you have, if you are an expert in one tool, then your career basically depends on it, but if you understand the concept and have good experience in multiple tools, then you will have broader domain.
In consulting, it is much easier to be an expert in one tool, you are not tied to one client and can find project somewhere else.
But if you are a permanent employee, then it helps to adjust your skillset as per the changing environment.
Having said that, you don't have to go after every tool in the market, try to diversify as per your interests and the market need.
Talking specifically about BODS, i have seen quiet a few clients using or planning to use it so its future looks bright, but then again, future can always change.
Thanks

Data migration to new macbook via external usb?

So I have a macbook pro right now and am looking at getting a macbook. I want to use the data migration assistant during the macbook setup to keep all my files, applications and things from the mbp.
The question is can I use a external usb drive to do this or does it have to be firewire? I wouldn't actually have both computers at the same time, so I would create a restore on the external usb and just plug that intot he new macbook. Would that do?
If not and I need firewire, would a simple usb to firewire adapter work?
Thanks

Patience sir. People who have an answer will post. If no one does, it's probably too esoteric for most. See "A Basic Guide for Migrating to Intel-Macs" at http://discussions.apple.com/thread.jspa?threadID=580146. That should get you started.

Low-Cost data migration and ETL tools

Hi, Im building a database for my company. We are a rather small size book company with a lot of references and still growing.
We have a Mysql database here and are trying to find some good tools to use it at its best. Basically we are just starting up the database after dealing with Excel: we had a size problemu2026 So im trying to find a program that will allow us to do two different things: the migration of our data from the old system to the new one and a specialized software to perform ETL (Extract, transform and load) on our database.
About the price of the tools, if we were one year ago, the accounting department would have been pretty relaxed about this. But today, we have some budget restrictions and therefore need a low cost tool. So could you give me some advice on a good data migration and etl tool for a low cost?
Thanks for your help.

Hi,
Some companies have budget problems and are having to reduce their cost of operation.
Have you ever heard of open source tools? They can do the job easily and less expensive than proprietary solutions that cost a lot of money.
You can have a look at a good ETL open source program called Talend Open Studio: it is user-friendly but also has advanced features intended for technical users (java debugger, code injectionu2026). It can perform data migration and ETL as you wrote in your first post.
The website is [here|http://www.talend.com/solutions-data-integration/data-migration.php] to download the open source program. They have a forum and documentation you can read. Tell us what you think about the software.
For an ETL benchmark: [ETL Benchmark|http://blogs.sun.com/aja/entry/talend_s_new_data_processing]

LSMW data migration porcess from the beginning

Hi gurus,
I do understand that there are 14 steps to be completed during migration, but can anyone give me a basic idea as what needs to be done prior to the above steps when starting a data migration project, as i have been only involved in the LSMW(14 steps) process before.
Thanks in advance, points will be awarded for all answers.
Ganga

Hello
As an intro:
Classical data migrations are typically limited to master data and
tend to cause multiple negative impacts on workflow and oper-
ating business units.
To minimize costs, risks, and effort during a data migration and ensure a smooth changeover for operational business processs items, and better reporting
capabilities SAP recently come with a Data Migration Solution called SAP Accelerated Data Migration tool.
This advanced tool, coupled with support from the SAP Services organization and SAP partners, lets you easily migrate and integrate application data from any legacy system into SAP applications and reduce migration costs significantly.
Data migration is done in 4th phase i.e. the final preparation stage of ASAP methodology.
As far as LSMW is concerned, BDC and LSMW both are use for loading data into SAP system. The difference is ,LSMW is loading tool by SAP where you can use various methods to upload, massage data or cleansed your data while loading into SAP from legacy system. The method can be BDC, BAPI, Idocs or SAP ABAP codes. Usually in BDC the user has to write an ABAP program or use other utility to load legacy data.
LSMW has been developed mainly for the Functional people who has no knowledge of the technical aspects of report or BDC in ABAP because its very user friendly and handy to use. So, simply they can upload the master records using LSMW.

Production order Data Migration

Hi All,
I want to perform data migration for production order. Please let me know how can I go about it either through LSMW or BAPI or IDOC etc.
Thanks,
Balaji

Hi,
I have done that but the problem is i am getting the information message "No process code can be found for the message type LOIPRO"
This is because I guess the basic type LOIPRO01 is an outbound idoc.
So please let me know whether it is possible with idoc method as this idoc is Outbound.
If possible, please let me know how it has to be done in detail.

Hi
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.
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.

HT4889 Data migration problems

I have gotten half way through data migration from my MacBook to my new MacBook Pro. It has taken an overwhelming length of time to get this far but the process has not progressed for 24 hours. How do I get out of this process without damaging my computers or the data?

Hello Mongoi and welcome to  Discussions.
The new Intel's cannot connect with some of the older iMacs via Firewire. I had the same problem, so instead I connected the two via File Sharing (Connect to Server using the Intel to connect to my old G4) and moved things across manually.
Click on this link for some detailed information about the differences between your old and new system, keeping in mind you will need to move things across manually.

Difference between "Data replication", "Data Cloning", "Data duplication" and "Data Migration"

Hi Gurus,
Can anyone tell me the difference between "Data replication", "Data Cloning", "Data duplication" and "Data Migration". I have gone through Google but doesn't find any appropriate answer for that where I can find the difference.
It would be highly appreciated if you give me a link for all and give me some point out.
Thanks & Regards

Here is how I see the terms used and understood by most folks
"Data replication"
This is the keeping the same data in sync in 2 different databases. Replication is the process of keeping data in sync between 2 environments/databases and not limited to Oracle to Oracle, it could be Oracle to MySQL to be kept in sync, MySQL to Oracle, Oracle to SQL Server, SQL Server to Oracle. The purpose of keeping data in sync can vary, but that is basic description of what it is.
"Data Cloning"
Make a copy of the data/database from one database environment to another, like for example taking production database and cloning the database to a pre-production database/environment for testing. Coning term is used more when copying a database not just data, but the whole database so typically you hear the reference "Database Cloning", but data cloning is basically the making a copy of the data from one place to another. Sometimes Cloning and Duplicating are used in the same way by folks as the basic end result is the same you are making a copy of the data to someplace else.
"Data duplication"
This is typically term when duplicating the data from one environment to another for a particular purpose, a lot of folks use "Data/Database Cloning" and "Data Duplication" in the same context, meaning they use them to mean the same thing, but I see more difference in the terms so when they are different Data Duplication is done when combining 2 databases to 1 therefore you can not clone the 2 databases into one so this term would be used more in those circumstances.
"Data Migration"
Moving data from one location/database to another location database, for example moving from MySQL to Oracle you would do a data migration from MySQL to Oracle as you are moving the data from MySQL to Oracle and going to leave it in Oracle. You could also be migrating to from Oracle 10g environment to a new Oracle 11g environment, therefore "Migration" is typically used when referring to moving the data from one environment to another and the source and target are different in location, database vendor, database version.
These are very simple ways of looking at the terms from my experience on how they are used.
