One to Many systems though MultiMappings??

Hi all,
With the standard message type like<b> Orders.orders05</b> , we want to send from one system to 4 systems depending on the RCVPRN.. and i need to create 3 Mappings bcoz we have different conversion rules for all the three systems.
Can i acheive it with single interface by using Message Mapping ?
or
Do i need to do separately for all the three systems??
Or
any other way??
Kindly suggest which gives better performance as well.
Thank You.
Regards
Seema.

hi seema,
               as your requirment, you can go for multimappping so no need to create 3 mapping.
go to <b>message mapping in ID</b>, there are 3 option , <b>design ,test and messages</b>.so go to messages.
give <b>your idoc in source and your 4 messages in target.</b>
same do in interface mapping.
this will solve your  problem.
but if you want to send your idoc on some criteria so you can use<b> corelation in BPM</b>
for this try this link , this is according to your scenario:
/people/sravya.talanki2/blog/2005/08/24/do-you-like-to-understand-147correlation148-in-xi   1:N mapping
hope this will help

  • Need help mapping one-to-many relationship

    [Sorry, inadvertently cross-posted]
    Hello,
    I have a one-to-many mapping question that's probably a no-brainer for the
    experts of the group out there. My problem is that I can't get a collection
    of Items for a given Theme to be populated and I don't know if it's a
    problem in my system.jdo or in my classes (or both). For example, for Theme
    10,
    I want a collection of two Items, item_ids 1 and 2.
    I have db tables named ITEM and THEME with the following layouts:
    ITEM
    |==========================================================|
    | item_id(pk) | item_name | item_number | theme_id(fk) |
    |==========================================================|
    | 1 | This is Item1 | 1234 | 10 |
    | 2 | This is Item2 | 2954 | 10 |
    | 3 | This is Item3 | 2094 | 17 |
    | 4 | This is Item4 | 946 | 11 |
    | ... |
    |==========================================================|
    THEME
    |=======================================|
    | theme_id(pk) | theme_description |
    |=======================================|
    | 4 | Space |
    | 10 | Town |
    | 11 | Train |
    | 17 | Pirate |
    | ... |
    |=======================================|
    I have two PersistenceCapable classes that map to the above tables:
    package com.lego.data;
    public class Item
    public int item_id;
    private String item_number;
    private String item_name;
    private int theme_id;
    public Theme theme;
    public String toString()
    return
    item_number+":"+item_name+":"+theme.getCode()+":"+theme.getDescription();
    package com.lego.data;
    import java.util.*;
    public class Theme
    public int theme_id;
    public String theme_description;
    public Collection items;
    public String toString()
    return theme_id+":"+theme_description;
    and here is my system.jdo file:
    <?xml version = "1.0" encoding = "US-ASCII"?>
    <jdo>
    <package name="com.lego.data">
    <class name="Item" identity-type="application"

    <extension vendor-name="kodo" key="inverse" value="theme"/>
    </field>
    </class>
    </package>
    </jdo>
    Thanks in advance for the help.

    Abe White wrote:
    The first thing to check is that you are always setting the "theme" field in
    your Items. If you add an Item i to the "themes" collection of a Theme t, but
    forget to also set i's "theme" field to t, then the change will never get
    written to the database.
    Next, make sure that whenever you set the "theme" field of an Item, you also
    set
    its "theme_id" field. You map both of these fields to the same column, so you
    better be sure they stay in synch.
    On a related note, you might try making the "theme_id" field non-persistent if
    things still aren't working for you. Mapping two fields to the same column
    might be causing trouble. It would be safer to make theme_id non-persistent
    anyway, and to always grab the id from the Theme stored in your "theme"
    field.
    Better OO programming and all that, though I can see that you might have
    performance issues in mind when doing it your way.
    Anyway, if you find that it works when you make theme_id nonpersistent, let us
    know and we'll see why the double-mapping of the column is causing problems,
    and hopefully find a fix.Abe,
    Thanks for the response but I'm still confused. I failed to mention that
    the Item and Theme tables are in an existing schema, so as you saw in my
    system.jdo, I am specifying application identity.
    Since this is an existing schema, the Item table has theme_id as the
    foreign key to the Theme table. So are saying that it is a problem to map
    the both theme_id as a data column and a Theme object in the Item at the
    same time?
    I guess what I don't understand is exactly what my system.jdo should look
    like to map a one-to-many relationship. In my case, from Theme (1) to Item
    (many). (See my system.jdo in previous post).
    Thanks

    Debug level Hibernate log excerpt:
    Included in the above description.

    That's not the right mapping for the 1:m relationship in Hibernate.
    First of all, I believe the recommendation is to have a separate .hbm.xml file for each class, so you should have one for Parent and Child.
    Second, you'll find the proper syntax for a one-to-many relationship here:
    http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html#tutorial-associations
    See if those help.
    The tutorial docs for Hibernate are quite good. I'd recommend going through them carefully.

  • How Many systems like ECC and BI can connect to EP server

    Dear experts
    I want to know ,how many systems can connect to one EP server,like ECC dev,qty and prd ,and BI dev,qty and prd with JCO and SSO connection...can you please clarify
    Thanks in advance
    Regards
    krishna

    Hi Krishna,
    The best practice is to have separate systems for Development, Quality Assurance and Production.
    Suppose you have One EP system, One ECC system, One BW System and One SRM system.
    Then your landscape should be designed as stated below.
    Development Environment:
    Here you work on new developments/bug fixes and enhancements.
    One EP System, One ECC system, One BW System and One SRM system.
    And all these systems must be connected to EP system.
    All of the above systems must reside in same domain.
    QA Environment:
    Here testing is done by testers/business.
    Once you complete development and unit testing you have to transport those objects to QA system.
    In this environment you have maintain all the systems similar to Dev Environment.
    Production Environment:
    This environment is for end users.
    It should contain all the above said systems.
    Here strictly no development/testing is not allowed.
    Objects are transported from DEV> QA>PROD.
    Regards,
    Nagireddy.

  • On how many systems can i install dreamweaver cs6

    About a month ago i have format my whole old pc with also dreamweaver cs6 deleted (i had troubles with my whole pc, thats the reason to format the whole pc) I sell the empty pc. only windows 7 on it.
    Now i have an new pc. and i have installed dreamweaver cs6 on it. it works ok.
    My question is: on how many computers can i install dreamweaver cs6
    I have in my home 2 times the program installed. one on this pc and one on the pc that i selled (The program dreamweaver cs6 was not anymore on that pc that i selled. I had deleted it)
    Now I would like to sell the adobe dreamweaver cs6, becaus i don't need it anymore. is this possible? because i had installed it on two systems in my home. one on this system and one on a system that i selled (deleted the DWcs6 on the selled pc).

    You seem to be asking two different questions.
    The answer to how many computers you can install Dreamweaver on is two. However, if you want to sell Dreamweaver, you must transfer the licence entirely to the other person. In other words, you can't keep Dreamweaver on one of your computers, and sell the other permitted installation to someone else.
    Details of how to tranfer the licence (or sell your copy) can be found here: http://helpx.adobe.com/x-productkb/policy-pricing/transfer-product-license.html.
    However, you say that you deleted your version from one computer. That's not enough. You should have deactivated it first. You will need to get Adobe to cancel the activation on the computer you no longer have. Otherwise, the person who buys from you won't be able to install on two computers.
    This is a user-to-user forum. If you need further help, contact Adobe Customer Support directly.

  • How just return one row of a one to many join..

    So I have a one to many join where the SMOPERATOR table has data I need however it has a couple of rows that match the JOIN condition in there. I just need to return one row. I think this can be accomplished with a subquery in the join however have not been able to come up with the right syntax to do so.
    So:
    SELECT "NUMBER" as danumber,
    NAME,
    SMINCREQ.ASSIGNMENT,
    SMOPERATOR.PRIMARY_ASSIGNMENT_GROUP,
    SMOPERATOR.WDMANAGERNAME,
    SMINCREQ.owner_manager_name,
    SMINCREQ.subcategory, TO_DATE('01-'||TO_CHAR(open_time,'MM-YYYY'),'DD-MM-YYYY')MONTHSORT,
    (CASE WHEN bc_request='f' THEN 'IAIO'
    WHEN (bc_request='t' and substr(assignment,1,3)<>'MTS') THEN 'RARO'
    WHEN (bc_request='t' and substr(assignment,1,3)='MTS') THEN 'M'
    ELSE 'U' end) as type
    from SMINCREQ
    left outer join SMOPERATOR on SMINCREQ.assignment=SMOPERATOR.primary_assignment_group
    WHERE SMINCREQ.owner_manager_name=:P170_SELECTION and SMOPERATOR.wdmanagername=:P170_SELECTION
    AND open_time BETWEEN to_date(:P170_SDATEB,'DD-MON-YYYY') AND to_date(:P170_EDATEB,'DD-MON-YYYY')
    AND
    (bc_request='f' and subcategory='ACTIVATION' and related_record<>'t')
    OR
    (bc_request='f' and subcategory<>'ACTIVATION')
    OR
    (bc_request='t' and substr(assignment,1,3)<>'MTS')
    order by OPEN_TIMe

    Hi,
    This sounds like a Top-N Query , where you pick N items (N=1 in this case) off the top of an orderded list. I think you want a separate ordered list for each assignment; the analytic ROW_NUMBER function does that easily.
    Since you didn't post CREATE TABLE and INSERT statements for your sample data, I'll use tables from the scott schema to show how this is done.
    Say you have a query like this:
    SELECT       d.dname
    ,       e.empno, e.ename, e.job, e.sal
    FROM       scott.dept  d
    JOIN       scott.emp   e  ON   d.deptno = e.deptno
    ORDER BY  dname
    ;which produces this output:
    DNAME               EMPNO ENAME      JOB              SAL
    ACCOUNTING           7934 MILLER     CLERK           1300
    ACCOUNTING           7839 KING       PRESIDENT       5000
    ACCOUNTING           7782 CLARK      MANAGER         2450
    RESEARCH             7876 ADAMS      CLERK           1100
    RESEARCH             7902 FORD       ANALYST         3000
    RESEARCH             7566 JONES      MANAGER         2975
    RESEARCH             7369 SMITH      CLERK            800
    RESEARCH             7788 SCOTT      ANALYST         3000
    SALES                7521 WARD       SALESMAN        1250
    SALES                7844 TURNER     SALESMAN        1500
    SALES                7499 ALLEN      SALESMAN        1600
    SALES                7900 JAMES      CLERK            950
    SALES                7698 BLAKE      MANAGER         2850
    SALES                7654 MARTIN     SALESMAN        1250Now say you want to change the query so that it only returns one row per department, like this:
    DNAME               EMPNO ENAME      JOB              SAL
    ACCOUNTING           7782 CLARK      MANAGER         2450
    RESEARCH             7876 ADAMS      CLERK           1100
    SALES                7499 ALLEN      SALESMAN        1600where the empno, ename, job and sal columns on each row of output are all taken from the same row of scott.emp, though it doesn't really matter which row that is.
    One way to do it is to use the analytic ROW_NUMBER function to assign a sequence of unique numbers (1, 2, 3, ...) to all the rows in each department. Since each sequence startw with 1, and the numbers are unique within a department, there will be exactly one row per departement that was assigned the numebr 1, and we''ll display that row.
    Here's how to code that:
    WITH     got_r_num     AS
         SELECT     d.dname
         ,     e.empno, e.ename, e.job, e.sal
         ,     ROW_NUMBER () OVER ( PARTITION BY  d.dname
                                   ORDER BY          e.ename
                           )         AS r_num
         FROM     scott.dept  d
         JOIN     scott.emp   e  ON   d.deptno = e.deptno
    SELECT       dname
    ,       empno, ename, job, sal
    FROM       got_r_num
    WHERE       r_num     = 1
    ORDER BY  dname
    ;Notice that he sub-query got_r_num is almost the same as the original query; only it has one additional column, r_num, in the SELECT clause, and the sub-qeury does not have an ORDER BY clause. (Sub-queries almost never have an ORDER BY clause.)
    The ROW_NUMBER function must have an ORDER BY clause. In this example, I used "ORDER BY ename", meaning that, within each department, the row with the first ename (in sort order) will get r_num=1. You can use any column, or expression, or expressions in the ORDER BY clause. You muight as well use something consistent and predictable, like ename, but if you really wanted arbitrary numbering you could use a constant in the analytic ORDER BY clause, e.g. "ORDER BY NULL".

  • One-to-many/foreign keys howto

    I have a situation where I'm trying to assemble a web of data and not make
    JDO mad.
    Here's the structure. I load this data in in batches, with an entry being
    placed in a load history table (H) to track each batch. Each batch
    contains primary (M) records associated with 0..n qualifying records from
    one or both of two auxiliary tables (D, L). All liberally salted with
    primary and foreign keys for referential integrity, and most of the keys
    are compounds, since the "M" identifiers get recycled for each batch load.
    Or, in other words, the "M" key is an ID plus an H key.
    Here's a map:
    H--0..n-->M
    __ +--0..n-->D
    __ +--0..n-->L
    Just to make things even more fun, the primary key of the H table is an
    Oracle 8 "DATE" type, which -- unlike ANSI SQL -- is actually a
    "TIMESTAMP". Kodo is rendering this as a java.util.Date rather than
    java.sql.Date, which is fine, because I need the full millisecond
    resolution. Interestingly, when I altered the schema type to "timestamp",
    load operations failed because the "column value was too big" according to
    Oracle.
    Also adding to the enjoyment, the actual order of presentation of data is
    that ALL M records come in, then ALL D records and finally ALL L records.
    I create my own H when the load starts.
    Now ideally, the whole shooting match will be a single pass/fail
    transaction, but that's for later.
    Right now, I can create the H, no problem and M's no problem. However,
    adding the D's and L's fails come commit time:
    kodo.util.FatalUserException: Attempt to set column "OFAC_ADDRESS.LOAD_ID"
    to two different values: "7/9/04 9:41 AM", "7/9/04 9:41 AM" This can occur
    when you fail to set both sides of a two-sided relation between objects,
    or when you map different fields to the same column, but you do not keep
    the values of these fields in synch.
    The granularity of the timestamps printed isn't making life easier, so I
    double-checked the D record's actual local value
    ADDRESS SERIALIZER A: Fri Jul 09 09:41:58 EDT 2004/Fri Jul 09 09:41:58 EDT
    2004
    ADDRESS SERIALIZER B: 1089380518179/1089380518179 (getTime())
    ADDRESS SERIALIZER C: -1541174818/-1541174818 (hashCode())
    I think I need a clearer understanding of what actions cascade here and
    what actions require manual help. For M, I did a setH(H) plus a
    setHid(H.getId()) and that made it happy. For D's and L's, of course, I
    also have to do a setM(M), where, because of the way the data comes in, I
    had to lookup the previously-stored M based on the M.id plus H.id.
    Now the parent objects contain sets of child objects. In theory, I should
    be adding the newly-created children to those sets, but in practice,
    setting the parent on the child appears to cause this to happen
    automagically, though I still have to manually set the local value of the
    foreign key field.
    I really need to find a good FM to RT. Online (and in the Kodo docs), I
    find a lot about setting up the XML for one-to-many mapping, but the Java
    coding side is taken as obvious. Regrettably, few things are obvious to me.
    I suppose I should excerpt the schema just for completeness:

    Hi Greg,
    I'm just using the unmodified schema-to-mapping output. The one thing that
    might be unusual is that I've broken up related tables into discrete

    Hi Tim,
    Could you send the your mapping information corresponding to the class that
    maps to table: OFAC_ADDRESS. In particular, I'm looking for what fields
    map to OFAC_ADDRESS.LOAD_ID. This will hopefully give us a hint as to
    what's going wrong.
    Thanks,

  • One to Many Again :(

    The problem that we currently have is to do with One-To-Many mappings. 1:1 and M:M work perfectly well. Only 1:M relations are not working properly the way we anticipate it to work.
    Consider the example:
    PurchaseOrder and LineItems. Each purchase order might have more than one LineItem and so PurchaseOrder class will have a list of LineItems and we map this list using 1:M mapping within the workbench.
    Toplink Behavior:
    In case of insert the foreign key in the child record is null and so it fails to insert.
    And some forums suggested that we have a backward relation. ie the child object should contain a parent object, which my opinion is very wrong because we are not really achieving 1:M relation, rather we are doing many 1:1 relations. Moreover having a parent object in the child and each parent having a list to me sounds like it might end-up in a circular reference ??
    Has anybody had any luck setting up 1:M properly without backward relation? Please share your experiences and workarounds.
    Regards,
    Murali

    Murali,
    Our FAQ covers this briefly listing alternatives:
    http://www.oracle.com/technology/products/ias/toplink/technical/tl10g_faq.htm#OneToOneBack
    I strongly recommend mapping all FKs as 1:1. In an ORM system these are actually the governing relationships and the 1:M are the optional associations. Mapping the 1:1 back-ref will create a much needed circular reference, which is easily managed in the model.
    The other options provided are also completely supported but will not provide the flexibility and performance of the 1:M + 1:1 solution.
    This approach is in line with all leading ORM solutions and is what you will find in the upcoming EJB3 specification as well.
    Cheers,
    Doug

  • RE:Placing a file in one of many directories at run time

    Hi all,I posted a question yesterday evening with subject name as "Placing a file in one of many directories at run time".
    The link for that qestion is as follows:
    [Placing a file in one of many directories at run time;
    For that question I got a UDF as a reply.The UDF is as follows
    DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory");
    String strDirectory = "Dir1"
    // here write your condition for dynamic Directory
    conf.put(key,strDirectory);
    return  strDirectory;
    Im having an double if condition in my scenario as follows:
    if (Integer.parseInt(TableName[0])==8 || Integer.parseInt(TableName[0])==10 || Integer.parseInt(TableName[0])==12 )
    if(CountryCode.equals("SG") || CountryCode.equals("MY") || CountryCode.equals("PH") || CountryCode.equals("TH") || CountryCode.equals("ID"))
    Now my question is  where to insert last two statements of UDF(conf.put(key,strDirectory);
    return  strDirectory;).
    Should I use both in if condition or any one in if condition.
    Can any one help me out in this case.
    Thanks in advance,
    Regards,

    Hi Naluvala
    You can do this. It is pretty simple
    bstractTrace trace = container.getTrace();
    trace.addInfo("In Dynamic Configuration...............................:");
    DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
    DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
    DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory");
    String ourSourceFileName = conf.get(key);
    trace.addInfo("Key Filename:"+ourSourceFileName);
    String valueOld = "/XD1_interfaces/messages/inbound/ref_payments";
    trace.addInfo("Key valueOld:"+valueOld);
    conf.put(key1,valueOld);
    return  ourSourceFileName;

    I think u r some confusion with productID and SuppliedID . primary key of one column( productId ) can be a foreign key of other table colum( SuppliedID). but foreign key( SuppliedID) can not be a primary key of second table .u declared SuppliedId as primary key . so ur mapping is incorrect.

  • One-to-Many:  New child not showing up when parent retrieved

    I have a one to many relationship. The parent contains a collection of children in a arraylist.
    A new child record is added independent of the parent, via a uow.
    The parent is retrieved.
    The new child doesn't show up.
    So the question is Does the parent first have to be retrieved and the child added to the parent. The child is not and should not be privately owned. The child is not dependent. If the parent goes away the child should still exist.

    "This last part" (as you describe it) is necessary. In a nutshell, you manage the object model (including both directions of a bi-directional relationship) and TopLink updates the database accordingly.
    This usually isn't a big issue. I.e., if you have a "addB(ClassB b)" method that looks like this, then you don't have to worry about managing the whole relationship all over the place:
    public void addB(ClassB b){
    bs.add(b);
    b.setA(this);
    At commit time the cache and database should be updated properly when you add a "b" to an "a".
    I have seen cases where the developer actually ended up not mapping the 1-M relationship in the model and had a "virtual" 1-M relationship. They would add a target to the "virtual" 1-M as you describe (just set the owner, i.e., tell the "b" it belongs to a particular "a". Then, they created a QueryKey in the Mapping Workbench in the Class "A" called "bs". Then they could build expressions and queries using "anyOf" through the "bs", even though it wasn't really mapped! I guess the point is that if you don't want to have to maintain that collection in code, and if it's not used in the application, then don't map it! Just create a QueryKey from A to B so that you can build the expressions as if it was there.

  • When we connect two bw systems to one R/3 system?

    Hi ,
    When we connect two bw systems to one R/3 system,
    could you please exlain what is the imact to SAP and BW in terms of query performance, batch performance,Develoment ,Quality system,security,BW Support.
    Thanks in advance.
    Regards,
    kranthi

    you can connect multiple BW to single R3 source system.
    In the delta queue (RSA7 in source system), you have a field with the target system, so you don´t have problem if you have many target bw system, because the data selection is done by system field.
    Challenge arises when you have multiple R3 feeding to single BW system and then you have to consolidate the master data say 0material fed from different source system R3 then you can consolidate data using consolidated infoobject.
    The following components concatenate to the key of a consolidated InfoObject:
    1)source system ID (two-character source system ID; permitted values are stored NW BI table RSSOURSYSTEM)
    2)one blank character
    3)backend object type (four-character backend object type; permitted values are stored BI table RSBWBEOTYP)
    4)master data key value as stored in the source system
    Note that the key of a consolidated InfoObject solely consists of non-integrated informations from the different source systems. Integration across source systems results from a (maybee repeatedly applied) data consolidation and cleasing process which unveils duplicate master data keys.
    Hope it Helps

  • Toplink mapping for one-to-many object inheritance

    Hi
    I currently have a Person object, extended by two specialist classes, PremisesLicenceHolder and PersonalLicenceHolder. I have mapped this in Toplink and it works fine saving a person into the specialist tables using the primary key person_id.
    However, a single Person may be extended any number of times by either one or both of the two specialist types. So, a Person may be a PremisesLicenceHolder many times over for different premises and licences, and also a PersonalLicenceHolder several times over.
    Is it possible to map this object model in Toplink avoiding duplicate person_id primary keys in the specialist tables?
    Thanks

    Hi,
    I am happy that my object model fits the problem domain. The Person and Organisation objects contain base information and have the primary keys person_id and organisation_id. It is important that there is no duplication of person and organisation records, no matter how many times they are saved in different roles.
    There are two types of licenceholder in the problem domain, and the ILicenceHolder interface defines information and methods that are common to both. The PersonalLicenceHolder object represents one of these types of licenceholder, and is always a person, so this class extends Person and implements ILicenceHolder.
    The additional information and methods that are required by the second type of licenceholder are defined in the interface IPremisesLicenceHolder, which extends ILicenceHolder. Premises licence holders can either be people or organisations, so I have two objects to represent these - PremisesLicenceHolderPerson which implements IPremisesLicenceHolder and extends Person, and PremisesLicenceHolderOrganisation which implements IPremisesLicenceHolder and extends Organisation.
    The model is further complicated by the fact that any single Person may be both a PersonalLicenceHolder and a PremisesLicenceHolderPerson, and may be so several times over. In this case, the same basic Person information needs to be linked to several different sets of licenceholder information. In the same way, any single Organisation may be a PremisesLicenceHolderOrganisation several times over.
    Sorry this is complicated!
    My initial idea for the schemas is to have Person and Organisation tables containing the basic information with the primary keys person_id and organisation_id. The Person table would have a one-to-many relationship with both the PersonalLicenceHolder table (pk: personalLicenceHolder_id, fk: person_id), and the PremisesLicenceHolderPerson table (pk: premisesLicenceHolderPerson_id, fk: person_id). There would also be a one-to-many relationship between the Organisation table and the PremisesLicenceHolderOrganisation table (pk: premisesLicenceHolderOrganisation_id, fk: organisation_id).
    I am flexible as to the design of my schema though, as I am happy to adopt any that will facilitate the Toplink Mapping.
    Thanks for your help with this.
