Upload master data tables from legacy systems with XI on BW

Hi developers,
Can you help me  to reconstruct the steps necessary for upload master data, deriving by legacy tables, on BW system using XI?
Thanks in advance

  • 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.

  • Customer master data updation from one system to another system

    HI  Experts,
    I have an issue with customer master data updation from one system to another system. And here only one field is not updating properly from one system to another system. and we found this is through idoc , but we don't find field in any segment.
    and the field is called ADDR1_DATA-HOME_CITY.
    and this will displayed as different city in address column.
    but as per the notes given in help , it is by program , form through only passing. but not able to trace and as per my analysis ADRC table , ADRNR  had this field HOME CITY.
    And this is for some customers updating wrong one from one system to another system , and for some customers field itself not updating in address column.
    please can you suggest any one. here are screenshot for your reference.

    that is not enough, it was enough in times before 40b release, but this was in the  last century
    Please read OSS note 384462 - Master data and addresses
    it explains what you have to do for ALE

  • 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.

  • 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 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

  • Master Data issue from external system to BW

    Hi,
    BW Version: BI 7.0
    Source System : Oracle D/B
    The Data will be processed by some external application and the processes Data will be stored in tables in Oracle D/B.I am extracting Data from Oracle Tables to BW.
    The issue i had is in the external application for example if we created a new Location ID,The new location ID won't be avaliable in Oracle untill i use it (assing it to any employee)
    Once i assign it to employee then the Location ID and Description will be avaliable transaction tables.
    Then in this cas how can i load master data to location ID in BW.
    or
    Thanks

    Hi,
    Simply create a Location ID InfoObject that will work as Master Data. Then create a datasource for the extraction of the Location ID Master Data (at least for the attributes, and probably for the texts as well).
    You can then schedule an update of this data everynight via process chains.
    All this will update the desired information independently from the transaction data.
    Hope it helps,

  • Master data tables with unwanted records from transaction data upload

    Hi Friends,
      I have a master data table for infoobject 'C' with compounding characteristics 'A' & 'B'.  I upload this master data with values given below:
        <i><u> A,              B,              C,           Short text,                        Long text</u></i>
           <b>  <b>P,          10,           BBB,         Apple,                              Big Apples
             Q,             20 ,           XYZ  ,       Tomatoes    ,                    Red Tomatoes</b></b>
      When I load data into ODS from a source system, I may not necessarily have data for all these 3 fields in these transaction record.  Example:
      <i><u>     A,                B,             C,             D,            E</u></i>    
         <b> P                -1            FFF</b>          20           30            
         <b> Q                10           GGG        </b> 10           40
       The problem is when I upload the above transaction data, it populates the <b>master data table</b> too with these two new records <b>1 -1 FFF</b> and  <b>2 10 GGG</b>, which I would like to avoid.
       Is there any way?
       Will assign full points to anyone who helps me here.
       Thanks,
       JB

    Hi JB,
    If you want to load transactional data and still want to prevent the population of the master data table, I don't think it is possible, as it is goes aginst the data consistency in the warehouse.
    However, if you can afford not to load transactional data for such cases, you can activate referential integrity check for the infoobject C. Then neither transactional data nor masterdata enter the datawarehouse until you maintain masterdata yourself for the infoobject C.
    hope this helps.

  • Data to be fetched from legacy system to SAP and doc needs to bee posted

    Hi Experts,
    I have a requirement where my client is using some application in Legacy system(Fuel Software) which receives fuel(Petrol, Deasel, CNG) in system and issue the same to company owned vehicles and wants that sap should be integrated and document also needs to be posted in sap for all the receivings and isssuences against their vehicles.
    Process Designed is:
    1. Required Data file will be picked from legacy system with some date stamp and will be placed in sap directory.
    2. There will be batch job which will check for new file based on date stamp.
    3. Will pick record n will pass to Goods_mvt_create bapi and then will post the document.
    4. We have created Vehicles as Internal orders in sap and whenever any issue will be there internal order no will be captured.
    5. By this way we are receiving and issuing in sap.
    Now my problem is i am stuck in designing step 1 and rest 2,3,4,5 steps have already been designed and working fine. Need your help in step 1. Else you may suggest some better way-out but again want to mention rest steps are already mapped
    Thanks in advance..

    Hi Ashutosh,
    You can use functions:
    FTP_CLIENT_TO_R3
    FTP_COMMAND
    FTP_COMMAND_LIST
    FTP_CONNECT
    FTP_COPY
    FTP_DISCONNECT
    FTP_R3_TO_CLIENT
    FTP_R3_TO_SERVER
    FTP_SERVER_TO_R3
    FTP_START_REG_SERVER
    FTP_START_SAPFTP
    FTP_STOP_REG_SERVER
    FTP_VERSION
    which allow you to connect from SAP ERP to any FTP server (if the legacy has it). You can validate the sample program RSFTP007.

  • Importing PO Receipts from Legacy Systems

    Hi guys
    My client has asked if it is possible to take approved/receipted
    purchase orders from a legacy system and upload them periodically into
    Oracle eBS - 11.5.8. That is all that is needed - there are no
    amendments or anything coming thru from the legacy system.
    If it is possible to provide the base material/ high level scope for a proposal for us to implement then it would be much appreciated.
    Thanks in advance
    Mike

    Hi,
    Do u need to upload approved P.Orders from legacy systems into apps?
    tehn we can use Interface programs for that for periodically.
    Create one concurrent programs by using interface tables.
    and make to run in the specified intervals.
    Is this ok?
