Use one as Many

Hi
When we use this node function why we need the third parameter ? We already mentioned the parameter to be used many times and the number of times it should appear by the first two parameters itself ? So why we need the third paramter ? I went through help website but couldn't make out
Radhika

this standard SAP example should clarify your doubt.

Third parameter is useful, for getting the same context changes from source to target.

Context Problem when using Use One As Many

Hi SapGuru's.
i have got a requirement in an IDOC To File Interface where the segments in the IDOC are like E1LFA1M->E1LFM1M->E1WYT3M

the EKORG Field from source is mapping to Purchase Organisation(field) in target file .
so here when i use one as many and iam mapping EKORG->MAP WITH DEFAULT ->USE ONE AS MANY and as in the above test data if there are multiple E1LFM1M's the first paramter of Use one as many is getting 2 ekorg's in only one context but here i want them to be created on separate context(please have a look at 4th E1LFA1M in the test data to get clear idea.
can any of you help me in this.

Hi,
Try this.
Source Code:
IDOC
--->E1LFA1M
                -->E1LFM1M
                      --> EKORG = 1000

                      --> E1WYT3M
                -->E1LFM1M
                -->E1LFM1M
                      --> EKORG = 1001
                      --> E1WYT3M
                      --> E1WYT3M
                -->E1LFM1M
                      --> EKORG = 1006
                      --> E1WYT3M

Use below Mapping:
Use If then Else Function.
1. If condition: E1WYT3M Exists
2. Then pass E1WYT3M
3. Else Pass E1LFM1M with "Map with Default"
Lets Consider Output of this step as "A".
Use One As Many.
First Input: E1LFM1M to exists to Split By Each Value
Second and Third Input will be Out Put of "A" (Above Step).
Lets Consider Out put of this Step as "B"
Use If without Else.
If "B" is true then pass "A" to exists.
Out put of this to Remove context to Target Vendor Master Node. In my sample it will be Node "Data"
Now for Mapping of Field Purch Org/In my case field "M"
Use If without Else.
If "B" is true then Pass "C". Output of this to Split by each value to target.
For C:
Use if then else
if E1WYT3M exists then pass EKORG else pass constant blank.
Hope its clear!!

"Use one as many "function

Hi All
I have a scenario from RFC to WSDL in which if certain conditions fulfil only then can I pass the value to the target field "SERVCODE".
The problem is there are many conditions which are to be fulfilled to have the value passed.
I tried using the function "use One As Many" but I got stuck at the "OR" condtion because its taking only boolean values.
Please have a look at the scenario and help me!!
Also I am preferring to have a graphical mapping but if nothing works out User defined function would do.

How to use one ResultSet many times in a jsp page ?

Hi all,
I have .jsp page and I have used it to get data from DB and display them to users. So I have to get data from DB in number of places in this particular jsp.
I thought that it is better to have one ResultSet for entire page and once it is done its job, the ResultSet will be closed and I can use it again and again like this.
Resultset rs = new ResultSet();
try{
    //My operations
}catch(Exception ex){
   //Handle Exceptions
}finally{
   rs.close();
}After above code snippet I can use same ResultSet again below the page.
I just want to know this,
1. is this a good coding practice?
2. Should i put rs = null; within finally clause?
any help will be appreciated
thank in advance,
Dilan.

Ok, Finally I switched my coding to use DAO and DTO, and I learned it through internet.
I removed all of data access codes from my jsp file(lets say 'functions.jsp'). I then created one interface and two clasess.
here is my DAO interface.
public interface UserFunctionsDAO{
    public List<UserFunctionsDTO> selectUserList();
}here is DTO class
public class UserFunctionsDTO{
    private String category = "";
    private String sub_category = "";
    private int cat_id = 0;
    private int sub_cat_id = 0;
    public UserFunctionsDTO(){}
    public UserFunctionsDTO(String category, String sub_category, int cat_id, int sub_cat_id){
        this.category = category;
        this.sub_category = sub_category;
        this.cat_id = cat_id;
        this.sub_cat_id = sub_cat_id;
    //Setters and getters will go here.
}my concrete data access class is like this.
public class UserFunctionsDataAccess implements UserFunctionsDAO{
    MyDB dbObject = null;
   private static final String SQL_GET_DISTINCT_CAT= "SELECT DISTINCT cat FROM cat_table";
   public List<UserFunctionsDTO> selectUserList(){
       dbObject = new MyDB();
       dbObject.sqlSelect(SQL_GET_DISTINCT_CAT);
       ResultSet rs = dbObject.getResultSet();
       ArrayList list = new ArrayList();
       while(rs.next()){
           list.add(new UserFunctionsDTO(rs.getString('category'), .......................));
       return list;
}I think now im following good coding practices, but I have one problem.
1. How do I retrieve this userlist from my jsp page?
2. Should I include UserFunctionsDTO in my jsp page as a bean?
3. If I include it, how can I get the list from it?
thanks in advance,
Dilan.

Message mapping: one as many, function node

Hi,
Check out this example from SAP, which demos the use of the function oneAsMany:

One to many relationships

Hi I have a big problem :)
I want to use one to many relationships.
One yable with primary key, foreign key view_id. The second table on the many side with primary key view_id and another primary key.
The problem is that ejbc gives the followin error:
" [java] In relationship 'ViewType-SView', role 'ViewType-Has-SView', a weblogic-relationship-role element contains the wrong number of column mappings. A single column mapping must be given for each primary key column in the bean referenced by the mapping."
And that makes no sense for me. Any ideas?

weblogic-relationship-role element column mappings should be the same as defined in
<ejb-relationship-role>
<multiplicity></multiplicity>
</ejb-relationship-role>

One to many subqueries?

Hi,all
I have two tables:
CREATE TABLE UserInfoTable (
loginId VARCHAR(32) CONSTRAINT pk_userLoginId
PRIMARY KEY,
regionId NUMBER(12),
accountId NUMBER(12) NOT NULL)
CREATE TABLE AccountTable
accountId NUMBER(12) NOT NULL PRIMARY KEY)
i have established the two master tables on the master site,but
when i create snapshot as:
CREATE SNAPSHOT test.AccountTable ON PREBUILT TABLE
REFRESH FORCE
START WITH to_date('20/12/2001 07:39:49 am','dd-Mon-yyyy
HH:MI:SS am')
NEXT /*1:Hr*/ sysdate + 1/(30*24)
FOR UPDATE
AS select * from [email protected] A where
exists (select 1 from [email protected] B
where A.accountId = B.accountId and B.regionId = 2)
i got the following error:
ORA-12013:updatable snapshots must be simple enough to do
fast refresh!
i have create snapshot log on userinfotable.accountId and
userinfotable.regionid on master site.but if i get rid of the
above "FOR UPDATE",then it works well.
this subquery is one to many subqueries?
the document of oracle 9i said:
Note: The materialized view site must have a compatibility level
of 9.0.0 or higher because fast refresh of materialized views
with one to many subqueries was not supported prior to release
9.0.0 of Oracle. The compatibility level is controlled by the
COMPATIBLE initialization parameter.
i use Oracle enterprise edition 8.1.7.so it can't do updatable
snapshots while using one to many subqueries?
Anybody can help me?i have wandered on this problem serveral
days.
thanks in advance!

One to many problem onan existing shema

I'm trying to do an insert in a database using one-to-many mapping.
I have two tables on an existing schema.
The two tables are:
ANAG
| ID_ANAG     | RAG_SOC |
|-------------------------|
|     1     | a name |
|-------------------------|
| ...     | .....     |

One ANAG can have m INDI. Given an ANAG I can find the related INDI(s)

How can I resolve the problem of the presence of IDANAG_ANAGRAFICAX and
have the 1-m relation?
Thank you in advance.
Mirko

I've changed the Indi class and the metadata but I still get an exception:
javax.jdo.JDOFatalDataStoreException:
com.solarmetric.kodo.impl.jdbc.sql.SQLExceptionWrapper:
[SQL=INSERT INTO INDI
(INDIRIZZO, IDANAG_ANAGRAFICAX, ID_INDI, IDANAGX) VALUES
('via 25 dicembre', NULL, -847766554, 0)]
ORA-00904: invalid column name
I know I'm missing something but I don't know what.
I can't find any simple example of a one-to-many mapping of two tables on
an existing schema.
The final SQL should be: INSERT INTO INDI(INDIRIZZO, ID_ENTITA, ID_INDI)
VALUES ('via 25 dicembre', -847766554, -847766554)
thank you in advance for help

You should not have both primitive fields for the data in the tables and
relations to other persistence-capable objects. So, your Indi class and
metadata should probably look something like this:
package domain;
public class Indi

private String indirizzo; //INDIRIZZO
private Anagrafica anagrafica;

Unable to read one-to-many relations using Hibernate

Hi,
I am trying with a very simple one-to-many relationship. When I am storing the objects, there are no problems. But when I am trying to read out the collection, it says invalid descriptor index. Please help.

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.

HT204380 When using facetime how many people can you be connected to at one given time? The reason for this question is I would like to utilize facetime for conference call meetings.

When using facetime, how many people can you be connectedto at once? The reason I ask this question is, I am wanting to conduct teleconference meetings with my staff who are spread out throughout the state and I would like to be able to have seven people in total connected to facetime at once.

Currently only one person. A lot of users want to be able to FT multiple users.
Send feedback to Apple requesting it. Maybe in a future iOS update or iPad it will be available.

HT204387 Hello! Can anyone teach me how to connect iphone 4S to ipad retina using bluetooth. I tried, but the devices won't discover each other at all. I just wanted to connect to share contact details so I don't have to key in one by one. Many thanks

Hello!

You need to go to the App stores and find compatible apps. iOS device do not natively have to ability to transfer info to a computer via BT to a computer.
With iOS 8 you can use AirDrop

One to Many Using an Interface

I have a one to many object mapping. There is a foreign key on the many table that is not being auto populated when it gets added to the one object. Is this normal activity? I would think that this column would not have to be explicitly set.
Also, I am using sequencing on the primary key of both the one object and the many object.
Following is a simplified code excert of what I am doing. Could I be doing something wrong?
Thanks,
Michael
public void testAddManyObject(OneObject oneObject){
UnitOfWork uow = this.getUnitOfWork();
ManyObject manyObject = new ManyObject();
uow.assignSequenceNumber(manyObject);
payoff.setRandomValue("10000");
oneObject.addManyObject(manyObject);
uow.registerObject(payoff);
uow.commit();
     }

(I am assuming that "payoff" is your "oneObject", otherwise I'm not sure of it's relevance in the example).
Does your addMany(Many aMany) look like this:
public void addMany(Many aMany) {
manyCollection.add(aMany);
aMany.setOne(this);
In other words, it's the 1-1 back reference that's really important in a 1-M... You shouldn't have to force the assignment of sequence numbers unless you want it for your business domain for some reason.
- Don

Use one as Many
