Reg: Efficient Strategy of Data Migration

Hello all, can anybody please help me whether is there any efficient strategy for doing the data migration.
looking forward for lots of replies.........

looking forward for lots of replies......... We'll need a whole lot more information before we can offer a reply. What are you migrating from? What are you migrating to? What constraints are you working under? Is data cleansing involved? Is data ttransformation involved? etc.
You should have been around these forums long enough to know that these sorts of drive-by questions don't get sensible answers with further details, and are, in fact, likely to provoke bristly responses. After all, if you can't be bothered to invest some time in typing in the question properly why should we give up our time trying to guess what it is you want to know?

Hi Ramesh,
From my exposure with indian company codes these are just another GL account to be migrated since there are
no dependies you can do the mapping from legacy to the new sap system the GL account.
Just my view

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.

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.

Data migration i Finance

can anyone help me how the <b>data migration</b> works in finance in short description

Hello
Data migration from legacy to SAP is responsibility of various module leads.
Assuming you are responsible for FI, the data could be GL /AP/AR/AA master data and balances.
While there are tools to upload, the first thing is mapping the legacy data with SAP data.
What fields are available in SAP and whether they meet the legacy requirements. After this excercise, the ABAPer would make a conversion program. This could be tested in any of the test clients.
As far as the field in PO are concerned, open a created PO, sit with a MM guy and decide on the mandatory fields and map with legacy.

Fixed Asset Data Migration Wizard

Hi All,
I tried to use Fixed Asset Data Migration Wizard to migration my fixed asset data from 8.82 to 9 in the development server. The server only accessible by myself.
When I start the migration run, system prompt me " To Continue with the fixed asset data migration, you must be the only user logged on to this company data".
In fact I'm the only user in the company data and system not allow me to execute the migration.
What are the causes that system recognise there is another user in the system?
Please advise.
Thanks in advance.

Data Migration for Open Purchase Order

Hi, All,
Is there anyone know how to Count the volume for Open Purchase Order. What's the normal strategy for the Data Migration and Cut-over stage?
My client want to know how many Open Purchase Order in the legacy system and then determine manual or automatic data migration. If manual, how to do? If automatic, how to do? Because all materials and vendors, plants are different number. How to track? How to find out to match between new and old?
Thank you very much

JC,
Sounds a bit early to be making decisions about the realization phase. It doesn't sound like you have finished the Blueprinting phase yet, much less the testing phase.
Anyhow, in my experience I typically use LSMW (Legacy system migration workbench) to load MM master data (material masters), Inventory (WIP, RM, FG, etc) Purchasing Master data (Vendors, Purchase Info Records, Source Lists, Quota Arrangements), and Purchasing transactional documents (POs, PurReqs, Scheduling Agreements, etc). Depending on the complexity and volume of data, it may be necessary to write custom programs to load the data. You will find this out during your requirements gathering.
It is uncommon but possible to load all of these data manually. I have never run across a client that wants to pay a consultant's hourly rate to sit at a terminal to peck away loading master data, so if the client intends to have his own users enter the data manually, the project manager should make provision that there will be qualified TRAINED client employees available for this data entry. I did help with a portion of a conversion once manually; of Sales Credits, but there were only about 30 SD docs to load. I did this the evening before go-live day, while I was waiting for some of my LSMW projects to complete in the background.
A good opportunity to 'practice' your data loads is right after you have completed your development and customization, and you have gotten the approval from the client to proceed from the pilot build to the full test environment. Once you have moved your workbench and customization into the client's test environment, but before integration testing, you can mass load all, or a substantial portion of your conversion data into the qual system. You can treat it like a dry run for go-live, and fine tune your processes, as well as your LSMW projects.
Yes, it is good practice to generate comparisons between legacy and SAP even if the client doesn't ask for it. For Purchase orders on the SAP side, you could use any of the standard SAP Purchasing reports, such as ME2W, ME2M, ME2C, ME2L, ME2N. If these reports do not meet the requirements of the client, you could write a query to display the loaded data, or have an ABAPer write a custom report.
You didn't ask, but you should also do comparisons of ALL loaded data - including master data.
It sounds like you are implying that the client wants YOU to extract the legacy data. For an SAP consultant, this is not very realistic (unless the legacy system is another SAP system). Most of us do not understand the workings of the myriad legacy systems. The client is usually expected to produce one or more legacy system technical experts for you to liase with. You normally negotiate with the technical expert about every facet of of the data migration. In addition, you will liase with business users, who will help you and the implementation team to logically validate that the final solution (turnkey SAP production system, fully loaded with data) will meet the client's business needs.
Finally, you mentioned how do you track the mapping of master data between legacy and SAP. There are many ways to do this. I normally try to get the legacy person do the conversion on his end, eg, when he gives you the load file, you would like to have already translated the master data and inserted the SAP relevant values into the file. If this is not possible, I usually use MS Access databases to maintain a master map, and I perform the mapping on a PC. If your data package is small, you can probably get by using MS Excel or similar.
Good Luck,

Data migration

Dear all my friends,
please help to share me about data migration before go-live FI system.
i plan to migrate GL acct balance, AP/AR open item and last 3 months historical data.
please help to show me : how should i do ?
thanks !

1. Normal GL Accounts: In this case line items are not required and totals are to be updated in SAP. This can be done using GL fast entry if the number is not too high.
2. Open Item Managed GL Accounts: All the open line items are required to be uploaded in SAP from Legacy in order to clear them. Hence, a LSMW / BDC program has to be developed to upload the line items.
BAPI_ACC_DOCUMENT_POST - for GL/AP/AR
BAPI_ACC_INVOICE_RECEIPT_POST - for AP
BAPI_ACC_GL_POSTING_POST - for GL
GL Balance
F-02 or RFBIBL00 or BAPI
Dr GL a/c Credit Data migration Account or Clearing Account
3. Customer & Vendor Open Items: All open line items in Customer and Vendor Accounts have to be brought in into SAP. For this also a LSMW / BDC program needs to be developed and upload the line items.
Vendor Balances
F-02 or RFBIBL00 or BAPI
Credit Vendor a/c (individually) and Dr Data migration Account or Clearing Account
Customer balances
F-02 or RFBIBL00 or BAPI
Dr Customers a/c (individually) and Dr Data migration Account or Clearing Account
4. Asset Accounting: In case asset accounting is implemented the individual balances of each asset (Gross Value and Accumulated Depreciation) have to be uploaded using transaction AS91. For this also you need to develop a LSMW / BDC program. Further, you also need to update the GL Accounts related to Asset Accounts with totals for each asset class T.Code OASV.
For uploading the Assets
AS91 -> for uploading assets in AA
OSAV --> for uploading assets in GL entry Dr Asset (individually) Cr Data migration Account or Clearing Account
You can use LSMW for uploading all these things
After uploading all, your data migration account will become zero

Confuse on PR & PO data migration approach new to MM module

Hi All,
I'm pretty confuse with the PO data migration approach when it comes to PO is GR or partial GR or GR&IR. I'm hoping that someone can enlighten me. i understand that we typically don't migrate PO when it is GR & IR, FI team usually will bring over to the new system as an vendor open item in AP. How about the PR or PO which have gone through or half release strategy? What is the follow up process? I have created a criteria table below. How Could someone point me in the right direction? Thanks in advance.

Hi John,
The approach that i have followed recently is that we have considered PO as the base document and converted other documents based on the PO condition. This means you first need to see if the PO is to be converted or not. Then you can proceed to convert the related documents like PR, Agreement, Info record, Source list, etc.
Also open qty for PO should be considered for Material and Service line items both.
Once a GR/SES is created, it gets updated in the PO history table EKBE with its related transaction/event type.i.e. EKBE-VGABE = 1 for GR and 9 for SES. Quantity and value also gets updated in case of material and services. You can compare this consumed quantities with PO quantity.
Please see below from SCN and let me know if you need more info on PR or PO conversion.

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 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.

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 11i to R12 Global - Open POs,lines, receipts & on hand upload, Is it possible to do the onhand qty upload with over riding of all receipts which uploaded against Open PO lines?

Hi Friends,
We are in a phase of data migration from 11i to R12
I was discussed with client & they wants extraction of all open POs which was generated after 01 Jan 2014 to till date in 11i.
Condition for open POs is PO qty-received qty=>0
critical Example for open PO is :PO no: 10 has 4 lines, 3lines full qty has been received & for 1 line partial qty(say 50 out of 100) received.
in this case he wants in R12 uploading as PO no:10 should entered as open PO with all 4lines & 3 lines complete receipt should be done, for 4th line partial qty i.e 50 should be received.
the question is if we upload on hand qty first, then open POs & receipts, it will increase the onhand qty in new system(mismatch of on hand qty's 11i to R12)
Is it possible to do the onhand qty upload with over riding of all receipts which uploaded against Open PO lines.
Or Please advice best solution.
Thanks & Regards
