    There are couple of them - Lawson ERP, Kalido, AS/400.  ECC 5.0 might be there as well.

  • Extracting data from Legacy system - How do we get the data into a normaliz

    Hi All,
    Requirement that I have now is to get the data from 6 different tables ORACLE database to BI using DB Connect, where in each of those 6 tables has the transactional data as well - If it is only 2 tables, would have been creating a view and get the data. Each of the 6 tables are linked to one other by the Primary Key and Foreign key relation ship.
    If it is from ERP system we would have created a Functional Module.
    Please advice me on how to get the data to BI end from those tables in Legacy system.
    Thanks in advance.

    Anil:
    I recommend following Ralph Kimball's EDW data modeling principles.
    Have a staging layer of DSO's with data dump from source system. So have 6 different DSO's extracting data from 6 tables from source system independently.
    Then have an integeration layer of DSO's depending on requirement. You could combine data from 2 or more DSO's here based on requirement and integrate your data here. Use primary key foreign key relationships here to do look ups or direct loads to do your business logic.
    Then have an analytical layer of InfoCubes, MultiProviders, InfoSets as required.
    The 3 layered architecture is a standard best practice that i have seen followed in many organizations. You could search for this type of architecture online under EDW (Enterprise Data Warehouse). There should be plenty of information available.
    Good Luck.

  • How to transfer data from legacy system  to SAP

    Hi Friends,
    I would like to know the process and the steps followed to transfer data from my legacy system to SAP.
    Suppose if i have all the data in the form of Excel sheet or doc type. How can i transfer this data into SAP.
    Please explain the steps followed.
    Appreciate your help
    Anil

    Hi ,
    Conversion of legacy data into SAP can be uploaded using a standard SAP Tool called LSMW ( TCode:LSMW).
    the below link gives a brief explanation of the LSMW tool
    http://tutorialsap.com/abap/sap-lsmw-tutorial-with-steps-to-create.html
    There are various methods to upload data within LSMW. If the number of records are very high like Article Master or  Conditions for Retail the IDOC method must be used.
    Standard IDocs
    1. Article Master - ARTMAS
    2. Conditions - COND_A
    3. Source list - SRCLST
    4. Customer Master or WRF3/WRF6 tables - DEBMAS
    5. Vendor master- CREMAS
    Etc. Use transaction code WE60 to see the structure of each of the idocs. New enhancements can be done for the idocs if the required field is not available.

    Hi,
    BO Integrator connects with other system (Database) and you will be creating your reports on the top of that DB or system. It never saw it being used to pull data from legacy to BW.

  • How to upload the data from legacy system database to SAP data base

    Hi.
    We are doing analysis of Legacy system and which needs to be converted to SAP system i.e. SAP implementation.
    I just want to know , how we migrate the existing whole data( from legacy system) into SAP system.
    and which method is the best method to use data migration from legacy to SAP system if data legacy data amount is huge.
    Please suggest me.
    Thanks.

    Hi
    We can either use the BDC or BAPI or LSMW  or Direct Input techiniques for the data transfers.
    The combination of both Session and Call transaction can be used to achieve this that includes the error handling also. This invloves the screen interaction.
    These days, BAPIs are used to overvome some upgrade problems. For easy upgradation, we cna go for BAPIs. Here ther is no screen intercation.
    LSMW mainly used for master data transfers using some standrad programs.
    As per your client or company desicions  we can choose any of them.
    Please refer to these links for more understanding -
    BDC Vs LSMW -

    BDC Vs BAPI -

  • How to extract data from ODS to non-SAP system

    Hi,
    Can anybody tell me, step by step, how to extract data from ODS to a non-SAP system?
    Is it possible to do it without programming effort? And is there volume limits for this kind of extraction?
    The non-SAP system is an unix system.
    Thanks in advance
    Ella

    Ella,
    You can look at it from the concept of a BADI / Infospoke
    Extract the data from the ODS to a Flat file / RDBMS using an infospoke. I am not sure as to how the infospoke loads data into the RDBMS ( did it very long ago ) but then you can push it into an RDBMS and I am sure it will be system neutral.
    Hope this helps...

  • Missing Data from Legacy System

    Hello All,
    My client went live end of January this year. They had a month of transaction data in their legacy system which they did not bring into SAP. Since this is their first year on SAP and recently implemented Extended Withhold Tax one month data is missing; when they run the 1099s at the end of the year they are going to be reported incorrectly.
    How can we bring over that missing data from legacy system over to SAP without having to clear those invoices in SAP?
    Thank You In Advance

  • Upload data from legacy system to SAP through ALE IDOC

    Hello All,
    I have a requirement where i need to upload the data from legacy system to SAP. So i am using ALE IDOC.
    In my requirement i need to extend the Standard IDOC. I have extended the IDOC and even found the exit for the updation of the extended fields to SAP. My data would be be placed in the application server.
    Can anybody tell me how to retrieve the data and update in the tables for the extended fields.
    Could you please provide a sample program for retrieving data for IDOC.

  • How to extract data from custom made Idoc that is not sent

    Hi experts,
    Could you please advise if there is a way how to extract data from custom made idoc (it collects a lot of data from different SAP tables)? Please note that this idoc is not sent as target system is not fully maintained.
    As by now, we would like to verify - what data is extracted now.
    Any help, would be appreciated!

    Hi,
    The fields that are given for each segment have their length given in EDSAPPL table. How you have to map is explained in below example.
    Suppose for segment1, EDSAPPL has 3 fields so below are entries
    SEGMENT          FIELDNAME           LENGTH
    SEGMENT1         FIELD1                   4
    SEGMENT1         FIELD2                   2
    SEGMENT1         FIELD3                   2
    Data in EDID4 would be as follows
    IDOC           SEGMENT                          APPLICATION DATA
    12345         SEGMENT1                        XYZ R Y
    When you are extracting data from these tables into your internal table, mapping has to be as follows:
    FIELD1 = APPLICATIONDATA+0(4)        to read first 4 characters of this field, because the first 4 characters in this field would belong to FIELD1
    Similarly,
    FIELD2 = APPLICATIONDATA+4(2).
    FIELD3 = APPLICATIONDATA+6(2).  
    FIELD1 would have XYZ, FIELD2 = R, FIELD3 = Y
    This would remain true in all cases. So all you need to do is identify which fields you want to extract, and simply code as above to extract the data from this table.
    Hope this was helpful in explaining how to derive the data.
