SAP Data Migration Framework

Dear All, I read from TechEd that SAP data migration framework involves using Business Objects data services. SAP has provided pre-built Jobs with iDOC as target.
All is fine but I came to know that we can use Data services as staging area and modify etc our data in Data services beforw loading into SAP ECC system.
I would like to kow more about using Data services as staging area. Does that mean that when we run jobs then data is stored in iDOC(XML file) on DS or it means we can run DS in demo mode where we don't load data but keep it within memory of DS. This is different from profiling and storing execution/DQ statistics. This is storing real time data in DS and then modify/analyze and then load in SAP ECC.
Can someone explain if we can run DS in demo mode without loading data?
Thanks,

Looking for Third Party SAP Data Migration Tools

Hi all,
I don't know if this is the right place but I was wondering if anyone can provide me a list or a link of the different third party SAP Data Migration Tools. I am specifically looking for productions that migrate data from one SAP system to another.
Thanks and I hope to hear from you.

Hi,
Just to weight out my options and compare the diffrent products as a research of sort.
For SAP tools they use LSMW I believe but I want to check the alternatives.

SAP Data Migration from R/3 4.6C to ECC 6.0

Hey All
We are planning to upgrade SAP R/3 4.6C to ECC 6 in near future. I am aware that data migration is not an issue as upgrade takes care of it all. What we are concerned with is that if after a few days of upgrade when the system is functional and users have performed some quantum of transactions on it, in case if the system fails then and we have to revert back to R/3 4.6C how can we get back all the information that we processed on ECC back to R/3.
I would like to know if anyone who has performed an upgrade, had some kind of fail over strategy for such a situation. Is there some tool we can use for this purpose?

Simple answer: not possible.
> I would like to know if anyone who has performed an upgrade, had some kind of fail over strategy for such a situation. Is there some tool we can use for this purpose?
No - there is no tool.
Table structures change, update programs changed - it's not possible to "roll back" that to a date and re-do it on 4.6c again.
Do minimize the risk I would copy the production system to a sandbox, do the upgrade and let the (key-) users test their functionality intensively.

RDS for SAP data migration through IDOC's

Dear Experts
Just now we have installed BODS 4.1 and RDS also installed now. I am in the process of exploring the RDS. I found all the migration objects is available in the form of IDOC's. Now my questions are
How to work on custom IDOC's. Do i need to extensively code on R/3 side to upload the custom fields. Like user exit or BADI for custom fileds
If yes then i would say implementation time through RDS will remain more or less same time.
Through BODS or by RDS migration objects is there any way without coding on ABAP R/3 side, Can we achieve migrating custom fields
Please let me how to achieve above requirements by RDS
Thanks
Vijay Mukunthan

Hi Vijay,
You are right, the standard content of the Rapid Data Migration RDS packages brings the content with the standard IDoc interface for SAP standard only. So custom objects are not pre-built with the package. However, we incorporated the foundation to include custom coding as easy as possible:
1) IDoc
We are using the standard interface technology IDoc. IDocs do have an enhancement concept which is described in the online help. There are three main cases and all of them are supported, however two need additional coding:
Z-fields: Additional fields in existing tables lead to IDoc segment extensions
With the IDoc segment versioning concept this is easy to realize without any ABAP coding
Z-tables: Additional IDoc segments will be necessary and lead to a new IDoc version
With the IDoc versioning concept you can easily add Z-segments with leveraging provided user exits
Custom business objects:
You can even create a complete own IDoc message type in Z-namespace for own stuff, leveraging the given ALE layer of the IDoc middleware
2) Enhancement guide
With the RDS package we offer an enhancement guide which helps you to modify the jobs and data flows in the SAP Data Services content according to the changes in the target IDoc structure to reflect additional fields and tables. We built it as a step-by-step guide following for a sample IDoc type but will work similarly for any IDoc.
Best regards,
Frank Densborn.

Oracle Legacy System to SAP Data Migration

Hi Experts,
New to data migration:
Can you guide me in how oracle staging is useful for data migration:
Here is my few doubts:
1. What is Oracle Staging?
2. How Oracle staging is useful for data migration?
3. I see few ETL tools for data migration such as Informatica, Ascential Datastage etc. but our requirement is how can we use oracle staging for data migration?
4. What are the benefits in using oracle staging for data migration?
Expecting your response of above queries.
Thanks,
--Kishore

Here is my few doubts:
1. What is Oracle Staging?It is where ODI creates temporary tables. It does the transformation and if required cleans the data aswell.
2. How Oracle staging is useful for data migration?ODI loads source data into temporary tables(staging) and applying all the required mappings, staging filters, joins and constraints. The staging area is a separate area in the RDBMS (a user/database) where Oracle Data Integrator creates its temporary objects and executes some of the rules (mapping, joins, final filters, aggregations etc.). When performing the operations this way, Oracle Data Integrator behaves like an E-LT as it first extracts and loads the temporary tables and then finishes the transformations in the target RDBMS.
3. I see few ETL tools for data migration such as Informatica, Ascential Datastage etc. but our requirement is how can we use oracle staging for data migration?
4. What are the benefits in using oracle staging for data migration?You can refer https://blogs.oracle.com/dataintegration/entry/designing_and_loading_your_own

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.

Data Services as a data migration tool

Hello All,
Has anybody used Data Services as a data migrition tool from a SAP ECC system? If so what is it like to use and are there any documents on this?
Cheers,
Nick.

Hi Nick.
About documents, here are some of them, but one that I think it could be useful for your understanding is the "BI109 SAP Data Migration" session: http://www.sdn.sap.com/irj/scn/shop?rid=/media/uuid/c08b931e-2a83-2c10-2aba-cb3968c5bc4e.
It shows the data migration framework based on SAP BusinessObjects technologies for legacy to SAP and SAP to SAP migrations.
More technical documents, showing how to set up iDocs, LSMW, etc:

HELP ME ON DATA MIGRATION PLEASE

Hi
what is SAP data migration what kind of tools and techniques include in that and also please what are the roles and responsibilities include in that when we are working on project.(RELATED TO ABAP)

Data Migration Current Situation
Data migration or data conversion is a persistent issue facing most organizations who have implemented SAP. Whether it is during the final phases of a new SAP implementation, during SAP upgrades and updates, during corporate restructurings, or during mergers and acquisitions, data migration continues to remain a challenging problem for IT.
Most data migration projects are faced with a time and budget crunch. But, these projects usually require extensive support from programmers and other technical experts and therefore data migration projects tend to get expensive and time-consuming.
The tools for data transfer and data migration provided by SAP are very technical and have a steep learning curve associated with them and they require technical experts to build and implement the data migration scripts.
Data Migration Ideal Scenario
An ideal data migration scenario would let the data migration project be implemented by the end user departments themselves. A few super-users within these end-user departments that supply the data should have the ability to transfer and migrate data themselves without relying on technical experts. Such a scenario would significantly cut the time and effort required in a data migration project.
Reaching such an ideal scenario would require data migration tools that are easy to learn and require no programming. Furthermore, these tools should work across all the different SAP modules and the SAP products, including the different versions of SAP.
Data Migration
Data Migration is the process of moving required (and most often very large) volumes of data from our clients existing systems to new systems. Existing systems can be anything from custom-built IT infrastructures to spreadsheets and standalone databases.
Data Migration encompasses all the necessary steps to cleanse, correct and move the data into the new system *. Technological changes, change in providers, software updates or data warehousing / data mining projects make such delicate and critical operations necessary.
<b>Data Migration can be done using BDC, LSMW, BAPI, Idoc's.</b>
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
Differences between bdc session method and call transaction method.
The most important aspects of the batch session interface are: - Asynchronous processing - Transfers data for multiple transactions - Synchronous database update During processing, no transaction is started until the previous transaction has been written to the database. - A batch input processing log is generated for each session - Sessions cannot be generated in parallel
The most important aspects of the CALL TRANSACTION USING interface are: - Synchronous processing - Transfers data for a single transaction - Synchronous and asynchronous database updating both possible The program specifies which kind of updating is desired. - Separate LUW for the transaction The system performs a database commit immediately before and after the CALL TRANSACTION USING statement. - No batch input processing log is generated.

Data Migration from SAP r/3 to SAP R/3

Hi all,
What is the best method to migrate data from one verison of SAP to another verison of SAP ECC say from SAP 3.1 to SAP ECC 6.0?
This is for all SAP modules including sd, mm, pp, fi, co master and transaction data. I know there are number of technologies to load the data such as LSMW, IDOC, ALE, DI, etc but what is the best way to extract all data feeds to be loaded back into SAP.
Thanks in advace.

Take a look to the following link, may be useful for you

if helpful reward points are appreciated

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.

Data Migration From Peoplesoft , JDEdwards To SAP.

Hi,
This is kiran here we are doing data Migration work from Peoplesoft And JDEdwards to SAP.in SAP side it involves Master data tables Related to Customer, Vendor, Material. and Meta data tables related to SD, MM, FI. We as SAP Consultant identified Fields from above tables and marked them as Required, Not required, And Mandatory. The Peoplesoft and JDEdwards flocks come up with the same from their side. Then we want map the Fields. as I am new to data Migration any body suggest me what are the steps involves in data Migration How to do Data Mapping in Migration Thanks in advance.
Thanks
Kiran.B

Hi Kiran,
Good... Check out the following documentation and links
Migrating from one ERP solution to another is a very complex undertaking. I don't think I would start with comparing data structures. It would be better to understand the business flows you have currently with any unique customizations and determine how these could be implemented in your target ERP. Once this is in place, you can determine the necessary data unload/reload to seed your target system.
A real configuration of an ERP system will only happen when there is real data in the system. The mapping of legacy system data to a new ERP is a long difficult process, and choices must be made as to what data gets moved and what gets left behind. The only way to verify what you need to actually run in the new ERP environment is to migrate the data over to the ERP development and test environments and test it. The only way to get a smooth transition to a new ERP is to develop processes as automatic as possible to migrate the data from the old system to the new.
Data loading is not a project that can be done after everything else is ready. Just defining the data in the legacy system is a huge horrible task. Actually mapping it to one of the ERP system schemas is a lesson in pain that must be experienced to be believed.
The scope of a data migration project is usually a fairly large development process with a lot of proprietary code written to extract legacy data, transform and load the data into the ERP system. This process is usually called ETL (extract, transform, load.)
How is data put into the ERP?
There is usually a painfully slow data import facility with most ERP systems. Mashing data into the usually undocumented table schema is also an option, but must be carefully researched. Getting the data out of the legacy systems is usually left to the company buying the ERP. These export - import processes can be complex and slow, sometimes specialized ETL tools can help, sometimes it is easier to use what ever your programmers are familiar with, tools such as C, shell or perl.
An interesting thing to note is that many bugs and quirks of the old systems will be found when the data is mapped and examined. I am always amazed at what data I find in a legacy system, usually the data has no relational integrity , note that it does not have much more integrity once it is placed in an ERP system so accurate and clean data going in helps to create a system that can work.
The Business Analysts (BAs) that are good understand the importance of data migration and have an organized plan to migrate the data, allocate resources, give detailed data maps to the migrators (or help create the maps) and give space estimates to the DBAs. Bad BAs can totally fubar the ERP implementation. If the BAs and management cannot fathom that old data must be mapped to the new system, RUN AWAY. The project will fail.
