How to Genarates Keys in MDM

Hi Frnds,
I want to know some more information about MDM Keys, Suppose i am having one Data Base Record its having 1000 employees information , I'm storing this document in MDM,But in Dta Base its already having Employee number for unique identification for each and every employee.
But My doubt, when i store the data in MDM data manager MDM will generate New Key's??
If its generate new key for each every employee, What happened to employee number in Data Base ??
Regards,
raj

Hi Raj,
There can be 4 approach for this:
1. Using MDM Auto ID - This is an inetrnally generated number by MDM and is unique by all means. If you want to take MDM's help to generate new ID for your Records, you can create a field in MDM with the type Auto ID.
In this, your record ID's remain intact.
2. Using Matching Merging Startergy of MDM- When you use this statergy of MDM, and merge two potentail duplicte records, you will have to merge their record ID also ( And that will become your Gloabl ID). But however, using remote keys, your Local ID will also be intact, however, on the Main Screen, only the Merged record ID will be seen.
3. You can have Auto ID of MDM and then use Assignment and generate a new ID. You can also use your Record ID and Auto ID together to generate a new number altogether.
4. You can only use your Record ID's. You do not have to mandatorily use the MDM ID. If your Record ID's are unique, it will be sufficient enough to identify each record.
I think, the last approach can be finbe if it suits your requirement.
Hope it helps.

  • Use of Foreign Keys in MDM

    Hi All,
    Is there any mean by which we can use Foreign Keys in MDM.
    Sighting an example.
    We have 3 table with fields:
    Products(Main Table): Material No( UF)
    Product Regions(Flat): Marerial No ( Foreign Key),Region: Lookup
    Prices(Flat): Material No( Foreign Key),Region: Lookup(Foreign Key),Price Type: Lookup.
    How is it possible to achieve the above mentioned scenerio.
    And are Foreign Keys same as Unique Fields in MDM. 
    Thanks

    Hi Manish,
    MDM server sits on the database server.
    The database server is a DBMS.MDM repository does not work with the tables and fields structure in exactly the same way as an RDBMS.
    So we do not use in the real sense the same Primary key Unique key concept.However we have the linkup/lookup field concept in MDM.
    Where a field in the main table can reference another field in the lookup table.
    So if you relate this to the RDBMS concept.The primary field in one table is the Foriegn key in another table.So in the lookup table we can refer a field of the main table.
    say for eg:
    You have a field Regions in the main table of type lookup flat.
    This field is actually used in the lookup flat table say lookup regions.
    This table has a field regions which is holding a legal set of values.
    So the field Regions in main table is used in the Lookup table as well.Where in the main table it was the linking field and in the lookup table it is the field holding the lookup values.
    So you can to an extent relate these 2 concepts but it does not precisily work in the same way in MDM.
    Hope It Helped

  • How to generate keys for the records

    Hi Gurus,
          can anybody explain me how to create keys for the recors while working with keymapping.
    Regards
    Ravikumar

    Hi Yugandher,
    Is your Question pertaining to Key generation in MDM or using the Remote key for importing and syndication in MDM?
    Remote Keys are system specific uniques maintained in MDM while importing source records from different source system.You need to Enable key mapping in Console and then map the <Remote key> field to the unique key in Import manager and do similar mapping in syndicator as well.
    You can view the key mapping for differnt records under the Edit key mapping (context menu) right clicking on any record.
    To know more on this refer the below link:
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/7051c376-f939-2b10-7da1-c4f8f9eecc8c  (Key mapping)

    For Key generation in MDM you can use the Qualified range property of Remote system in Console for Key genearation.However these keys will be genearted only after syndication and are created and assigned within MDM and not maintained from any source remote system.

  • How to set key fields in a Database view

    Hi guru's
    iam balaji,plz guide me with how to set key fields in a view.......that field is a non key field in the base table....
    thanks in advance,
    Balaji.S

    take a look at this:
    Diagnosis
        In the view, not all of the mandatory fields were included as key
        fields. The key of the view therefore is not unique.
    System Response
        All the fields are regarded as key fields in order to guarantee that th
        key lengths are unique.
    Procedure
        For views with a large number of fields, this could have a negative
        effect on the performance for the language construction described below
        In this case, all the mandatory key fields should be included in the
        view.

  • How to get key and text value of field "TNDRST" in VTTK from R/3 into BI

    There is one field call "TNDRST(Tender Status)" in SAP table VTTK in R/3. We can find  key value, but we are unable to find text for this field in VTTK. However we can see text value if we double click domain:TNDRST and go to value range.
    Questions, how to get key value and text of TNDRST together in BI. Do we need to create a master data source for TNDRST text information in R/3 and extracting into BI, if yes, how to? Are there any easy way to do it??
    Thanks,
    Sudree

    Hi Sudree,
    You need to create a generic Text Datasource to extract this information into BI System.
    1. Create a generic DS based on Table: DD07T
    2. The fields should be put in the extract structure.
              DOMNAME (Make this as Selection in the DS ) -
    Filter the Domain Name
              DOMVALUE_L -
    Key Value of Tender Status
              DDTEXT -
    Text / Description
              DDLANGUAGE -
    Language
    3. DD07T is the table with all the Domain names & their values, so in the Infopackage enter the Selection Value for DOMNAME as 'TNDRST' and then run it.
    Or you can create a view out of this table based on DOMNAME filter as 'TNDRST'.

  • How to get keys of a particular type

    Following are my objects:
    DepartmentKey - primary key is departmentName, a String
    Department
    EmployeeKey - primary key is employeeId, an integer
    Employee
    I have 5 DepartmentKey-Department key-value entries in a cache and 2000 EmployeeKey-Employee key-value entries in the same cache.
    How do I get all the DepartmentKeys from the cache? In general, how to get keys of a particular type (class name)?
    Thanks
    Ghanshyam

    I guess I am deeply off track regarding the general approach towards storing items in the cache.
    Following is my problem domain:
    A Merchant is any establishment that accepts credit cards. (It could be the local Subway down the street or Macy's, etc.). A Transaction is a credit card transaction.
    public class Merchant implements Serializable{
    private String merchantId; // primary key
    private double averageTxnAmount;
    private double totalTxnAmount;
    private long totalTxnCount;
    public class Transaction implements Serializable{
    private String merchantId; // merchant that originated the txn
    private double amount;
    private Timestamp txnTime;
    private String txnType; // sale, return, etc.
    public class MerchantKey implements Serializable, KeyAssociation{
    private String merchantId;
    public Object getAssociatedKey{
    return merchantId;
    public class TransactionKey implements Serializable, KeyAssociation{
    private String merchantId;
    private Timestamp txnTime;
    private double amount;
    public Object getAssociatedKey{
    return merchantId;
    I want to update a merchant's average txn amount as transactions come in.
    Let's say I have a million merchants in a partitioned cache cluster spread across some machines.
    Transactions come into the cluster quite rapidly, say tens in a second. The process that inserts the transaction into the cluster must also update the merchant to which the transaction belongs, as follows:
    Transaction t = ...
    cache.put(tKey, t); // store the transaction into the cache
    MerchantKey mKey = new MerchantKey(txn.getMerchantId());
    Merchant m = (Merchant)cache.get(mKey);
    // update the merchant's avg txn amt
    m.setAverageTxnAmount((txn.getAmount() + m.getTotalTxnAmount())/m.getTotalTxnCount() + 1);
    m.setTotalCount(m.getTotalCount() + 1);
    // store the updated merchant back into cache
    cache.put(mKey, m);
    OR
    Transaction t = ...
    cache.put(tKey, t); // store the transaction into the cache
    MerchantKey mKey = new MerchantKey(txn.getMerchantId());
    Merchant m = (Merchant)cache.get(mKey);
    MerchantUpdater agent = new MerchantUpdater(t);
    cache.invoke(mKey, agent);
    public class MerchantUpdater implements AbstractProcessor{
    public Object process(Entry entry){
    Merchant m = (Merchant)entry.getValue();
    // update m's avg txn amt, total count using t
    entry.setValue(m);
    The basic idea is to store all merchants and all transactions (which could be tens of millions in a day) for a day in memory and to update the merchant objects as transactions come in throughout the day. The above example shows updating just the merchant's average txn amount, but in reality, it could be updating a number of things about the merchant.
    Am I using the api in the right spirit or is my approach seriously whacked? Can you please comment?
    Thanks

  • How to define keys in target DSO

    hi gurus!!
    ..can you please extrapolate on how to define key in target DSO and transformation logic.. (please refer to below discussion from for scenario from earlier posting)
    thanks in advance
    I have data from 3 datastore objects which I need to update one infocube. However, I need the data to come together to form one line per record. I've found that if I update the cube directly from the 3 DSO I get 3 lines rather than one, and if I update them all to a DSO and then to the cube, the same thing happens because I take the data from the change log.
    If I go via an InfoSet, I can not do a delta upload to the cube.
    I need this to run a min of once an hour.
    Any tips or advice would be greatfully recieved.
    Thanks
    Alice
    answer:::::
    You need to have an common key fields set in all of the three transformations.
    In your case it is probably:
    The key in target DSO is: k1..k3
    ODS1 - updates key k1, leaves k2, k3 empty
    ODS2 - updates key k2, leaves k1, k3 empty
    ODS3 - updates key k3, leaves k1, k2 empty.
    If you have it that way, you will end up with three records, instead of one.
    k1, empty, empty
    empty, k2, empty
    empty, empty, k3
    To resolve this, all of the source DSO must be able to determine and set a common key part in the transformations.
    Target ODS:
    Key K1,
    ODS1 - updates K1, key figures/characteristics from ODS1
    ODS2, updates K1, key figures/characteristics from ODS2
    ODS3, updates K1, key figures/characteristics from ODS3
    result:
    K1, key figures/characteristics from ODS1, then
    K1, key figures/characteristics from ODS2 - result is - previous record's key is overwritten, but the key figures/characteristics are mapped to the correct infoobjects (depending on how you set the transformation....)
    K1, key figures/characteristics from ODS3 - as for ODS2.
    The final result:
    K1, key figures/characteristics from ODS1, key figures/characteristics from ODS2, key figures/characteristics from ODS3.

    Hi,
           As thomas said you maintain your keys same as your source DSO's  in the target DSO.This is how the procedure goes when no specification for the keys are given.So maintain same keys which are in the sources.

  • How to Genarate a Unique ID for each Payload in XI

    Hi,
    My Question is How to Genarate Unique ID for each Paylod that we send in a particular Interface.
    Is that we can do it in Mapping...If Yes, How its possible...
    Thanks
    Amaresh

    Hi Amaresh !
    XI generates and stamps a messageID to each message header. That ID is unique. You could use that one. To get that number from inside message mapping to put it in the payload, you could use a java UDF with this code:
    String msgid;
    java.util.Map map;
    map = container.getTransformationParameters();
    msgid = (String) map.get(StreamTransformationConstants.MESSAGE_ID);
    return msgid;
    Of course you can generate another number, but maybe you will need to use a common storage to avoid repeating the assigned numbers, and that will require more work.

    This is exactly the type of problem that I'm currently trying to figure out. I'm trying to following your solution but I'm not clear on how you actually achieved this in you last note. I want to dynamically select actuals/budget column fields based on what period I enter. I thought about creating 12 separate RKF fields for actuals and 12 separate RKF fields for the budget reforecast and outputting these all and then doing some VBA to hide the fields not required based on which period was selected... how is your variable ZFYAPER7 defined and calculated?

  • How to specify key in CDS view?

    I defined a CDS view based on an entity. When I activate, it says:

    However, I am at a lost how the specify key in CDS View. The developer guide did not mention anything. If I put a key before one of the attribute:
    Cannot find sub artifact "key" in "Application"
    My CDS view is as follows:
    view ApplicationView as select from Application {

    hi Atul kumar jais
    You have to create a text variable using replacement path for processing type and give the reference object which is the object which you created variable for, "replace with" one with key and anther one with text. Then you can display that in the header of the column or if you are using custom template, you can use webitem for it.
