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

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

Upload Opening balance of G/L accounts from legacy system to SAP, and also

Hi Gurus,
How to upload Opening balance of G/L accounts from legacy system to SAP, and also Vendor and Customer balance.
My Doubt is when you upload the customer balance and vendor balance will it effect the sundry debtor account and sundry creditor account if not the how will the sundry debtor account and sundry creditor account will be posted with the balance. Please send me the general entry passed for posting the same.
What I understood is that when we are uploading the customer and vendor balances through LSMW, no entry will be passed and it will update the customer and vendor sub ledger in FBL1N and FBL5N but it will not affect the sundry debtor account and sundry creditor account.
To give effect to sundry debtor account and sundry creditor account we need to manually pass a journal entry as follows.
1) Sundry debtors account A/c -
DR
      TO clearing account A/c
2)     clearing account A/c -
dr
     Sundry creditor account A/c
Please let me know whether iam correct
Also please tell me what will be the scenario for uploading of the assets balances through LSMW.
THANKS AND REGARDS
MV

Hi,
     When you uploading any data from legacy system to sap normally we will be using LSMW or BDC,thru this we will be uploading master data like G/L,vendor,Customer and asset master these are the some examples and we will upload transaction data also that is P&L Account and Balance sheet.When we do uploading data thru LSMW system will update all the values of vendor,customer and asset values as well as subsidary ledger also.No need to do manully.

Loan upload from legacy system to SAP

Hi Experts,
I have a query regarding uploading Loan from legacy system to SAP.
We are implementing SAP HR for a client going live by 1st jun 2011. The scenario is the client has few employees who have taken loan for various reason, i have configured the same through SPRO....now my query is when i ask the client to provide me with loan data:
1. We are running payroll from 1st April 11, should i ask the client to give me the loan amount as the current standing loan amount
2. when i am uploading loan in 0045, should i put something in third tab payment
Thanks for your support.
Regards,
Jyoti

Hi,
This third tab basically create a record for info type 0078(Loan Payments). If you don't have any records in 3rd tab/0078, system will not start loan recovery in payroll.
Find the response for 2 scenarios-
Scenario 1 & Scenario 2:
maintain these fields in the table control of 3rd tab-
Date(GT_PAYM-ZAHLD) - 01.04.2011....Basically payments and repayments starts date also used for interest calculation
PmntTyp(GT_PAYM-ZAHLA) - 100(Loan payment (external)) ....Contains information on the direction and method of payment. Also control wage type generation in loan PCR and Functions
Amount(GT_PAYM-BETRG) - Balance Amount ....The total of payment or repayment amounts which you enter here, may not exceed the amount that you have entered in the Approved loan amount field on the Basic data tab page ....For your both of the scenariof, this amount will be same.
Regards.
