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,
Pushkar Patel

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 R3 to new ECC System

Hello,
We are doing a fresh implementation for SAP MDM. Currently we have 3 SAP R/3 systems and 1 non-R3 system (BPCS system). One of the project goals is to do data migration from all these 4 systems into a new SAP ECC system and to MDM for Vendor Master, Customer Master and Material Master. My manager says that we need Business Objects tool to Migrate these data. But, my question is that is it not possible to achive this through XI/PI itself ? Can anyone let me know the entire process in XI/PI as to how do I receive the Idocs from R/3, convert into XML and then send it to the new ECC system in Idoc format ?
Thks & Rgds,

Hi Gandhi,
You have SAP MDM, BPC and R/3 systems in your landscape, when you are migrating data to new ECC system, what is the role of mdm, did you moving the same data to MDM to avoid duplicate/redundant data??is there any data migration from R/3 to MDM(any integration required)or MDM to R/3,
You have to develop different interfaces to transfer data from MDM to ECC, BPC to ECC.definelty you required one middleware, the option definitely SAP PI. it offers very easy of integration between MDM and R/3 system, you can use MDM-PI adapter to connect to directly MDM syndicator file port from there you can pull the XML file and convert it in to IDoc format use Receiver IDoc adapter in PI, the same way we can integrate BPC system with R/3.
Search in sdn, there are some scenarios integration of R/3 and MDM using PI, refer those links, if still you have any doubts let me know,

Data Migration from 4.7 to ECC 6.0

Dear Friends,
We are doing upgration from sap4.7 to ECC6.0.
We have activated new gl. We have configured all ecc6.0 functionality.
But we stuck on data migration from classic gl to new gl.
We want to activate the migration cockpit but system is asking license key.
My question is, which license key it is?
From where we will get this?
Kindly don't send me any links and any documents related to ecc6 functionality.
Please guide us on this.

Data Migration from 4.6C to ECC 6.0

Hi all,
Can you suggest me solution for data migration from 4.6C to ECC6.O which technique to be used!!
if you have the documents regarding the above post it which will be useful!!!
Thanks,
Yogeshwaran K S

Hi Yogesh
OS migrations are more or less painless beside the fact, that most "Unix" operating systems are using a different endianess (aside from Solaris on X86_64). For RFC and other SAP proprietary communication this is done in the kernel but if you use own software to read BINARY data (not talking about textfiles) you need to take care of that in your software.
Hope ths helps

Data Migration from Legacy System in CRM

Hi All,
We are going to Implement a new CRM project, I have a problem with LSMW(Legacy System Migration Workbench ), I have some Conversion Objects of CRM and I need to know whether Data Migration is possible or not, please tell me how to find these Objects and how to know Data Migration is possible or not.
Objects are like.,
1. Accounts
2. Actuate Reports
3. Active Campaigns/Campaign Content/Dispositions
4. Contacts
5. Contracts
6. Opportunities
7. Payment Arrangement History
8. Payments
9. Premises
10. Rate Changes
11. Security Deposits
12. Business Partner Relationships
13. Web self-service information
14. Usage that has been used for quotes
15. Tax history information, including AXCIS
17. Service Requests
18. Service Order History
19. Security Deposits
20. Reference Values
21. Rate Changes
Can anybody please tell any transaction code in CRM where can I find the Data migration for the above objects is possible or not.
Thanks in Advance,
Sai.

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

HR Payroll Data Migration from 4.6C to ECC Upgrade

Hi
We are going to Upgrade our 4.6c R/3 system which includes HR to ECC6.
After this upgrade we going to start the Data migration of all data inclduing HR payroll from 4.6c to ECC.
1).Can anybody advise what are the options for loading Payroll data from 46c to ECC ..? After Payroll data migration we must be able to see all the Payroll results from the previous system.
2) is there any standard programs availble for Payroll data migration ..?
Also if anybody have any info/links on Payroll/HR data migration please help to advise.
Thanks a lot for your info/Time.,
Edited by: Dp on Apr 3, 2008 11:41 PM

Hi Somar,
I could not find the mentioned post "HR Upgrade". Please let me know the details of the "HR Upgrade" details which need to be kept in mind during upgrading R/3 4.7 to ECC 6.0
Yes, we have got the list of "Modification Objects" using the SPAU. Please confirm that during our upgrade, we just need to work on these objects which were changed/repaired by us according to our business need.
And, apart from that, please let me know should I need to worry about any OSS notes specific to 4.7, which is not applied to our system and got released after the ECC 6.0 Enhancement Release 3.
I understand that if we have a system that has the Patch and SP level as in our production system and do the upgrade to ECC 6.0 all the HR functionalities will be automatically taken care. Please confirm.
Thanks in advance for your help.
Regards,
Vijay

Data migration from 4.7 system to ECC 6.0

Hi All,
I am a Solution Architect. Currently working on a typical pursuit requirement. the requirement is as below:
One of our customer is currently on SAP 4.7 system. Their current system is shared by 2 companies & the companies got demerged now. Hence they are palnning for fresh ECC 6.0 implementation & migrating Master data & transactional data related to this customer from the current 4.7 system to ECC 6.0.
I am seeing possible way for data migration is through ALE or LSMW. But I am not confident about the execution plan & process.
I would wish to know from you people is:
1. The different methods to do data migration from 4.7 to ECC 6.0 with pros & cons
2. How to plan for data migration
3. Risks & mitigations during data migration
4. different kind of skill set & duration required to accomplish this requirement
Currently we are planning for 6 months for the ECC 6.0 core modules implementation.
If you have undergone this kind of project then request you to share your experience. Any information on this regard is appreciated.
Thanks & Regards,
Suresh

Data load from Legacy system to BW Server through BAPI

Requirements: We have different kind of legacy systems and SAP BW server. We want to load all legacy system data into SAP BW server using BAPI. Before loading we have to validate all data. If there are bad data, data missing we have to let the legacy system user/ operator knows to fix the data into their system with detail explanation. When it is fixed, we have to load the data again.
Load Scenario: We have two options to load data from legacy systems to BW Server.
1. We need to load data directly from legacy system to BW Server using BAPI program.
2. Legacy Systems data would be in workstations or flash drive as .txt (one line separated by comma) or .csv file. Need to load from .txt /.csv file to BW Server using BAPI program.
What we want in the BAPI program code?
It will Read / Retrieve data from text / csv file and will put into the Internal table. Internal table structure would be based on BAPI InfoObject structure.
Call BAPI InfoObject function module BAPI_IOBJ_CREATE to create InfoObject, include all necessary / default components, do the error check, load the data and return the status.
Could some one help me with the sample code please? I am new in ABAP / BAPI coding.
Is there any other better idea to load data from legacy system to BW server? BTW we are using BW 3.10. Is there any better option with BI 7.0 to resolve the issue? I appreciate your help.

my answers:
1. this is a scendario for a data push into SAP BW. You can only use SOAP-Based Transfer of Data.
http://help.sap.com/saphelp_nw04/helpdata/en/fd/8012403dbedd5fe10000000a155106/frameset.htm
(here for BW 3.5, but you'll find similar for 7.0)
In this scenario you'll have an RFC dinamically created for every Infosource you need to transfer data.
2. You can make a chain for each data load, so you can call the RFC "RSPC_API_CHAIN_START" to start the chain from external.
the second solution is more simply and available on every release.

Sergio

Data conversion from legacy : through BOM or recipe for a process industry?

Hi all
I am working on data migration document for BOM , ROUTING, PROD VER. My question is whether during migration from legacy we should first migrate the Recipe and add the comp no for creating BOM in mass creation , Or that we should bring the BOMs directly from the legacy? Which method is better from strategic point ?

Data Migration from CRM 5.0 to CRM 7.0

Hi Friends,
We are into a re-implementation on CRM 7.0. The old system was on CRM 5.0.
Since this is not an upgrade, the data will not copied over from the old system into the new system.
So, now I would like to know how to migrate data (master/transaction) from CRM 5.0 into 7.0.
I have read that we can make use of BAPI/LSMW/IDOC/XIF adapters to push info into CRM.
But, the customer wants all the historical data to be in the new system.
I think master data can be handled.... but how to migrate the transaction data?.... i mean the number ranges/document flow.. and other relationships.. how can we maintain the same links into the new system?
If it was a migration from legacy system into the SAP CRM, we could have gone ahead with new number ranges etc... but this migration is from SAP to SAP.
Also, we will have ECC6.0 connected to CRM 7.0. ANy additional things to be taken care of when the connection is live in DEV/QA/PROd instances?
Any pointers to this ?

Hi Gary,
As per my understanding, your data migration involves quite complex scenarios covering the CRM and ERP box. As the customer needs the old data to be present in the new implementation, the old data needs to be migrated from the CRM 5.0 to CRM 7.0. For the migration to happen, you need to setup the customization (like the number ranges,Condition Data Tables, etc ). Then only you can proceed with the data migration. Also, you need a proper backup plan as this involves proper backup of the data.
Once the setup is complete, you need to configure the ECC6.0 with the CRM7.0 system. Here also, you need to do a lot of settings and performing the Initial loading of the Adapter Objects. But before you proceed with the entire operation, the entire system landscape must be properly defined with appropriate settings.
My recomendation is to take help of SAP Consultants and data migration experts as they are the best persons to guide you on this. Also it would be great if you can go through the SAP Best Practices documents which are best repository documents to guide you on this.
Have a look on this link for an overview of the CRM Data Migration
http://help.sap.com/saphelp_crm60/helpdata/en/1a/023d63b8387c4a8dfea6592f3a23a7/frameset.htm
Hope this helps.
