Datacontrol Issue ... Parent Child Relation

Hi,
I got to see a weired behaviour with Datacontrol. Here is how, i created my datacontrol:
1.Created a Child class named 'Person' with class variables 'firstName','lastName'. And generated accessors for them.
2.Created a Parent class named 'Employee' with class valiables 'empId' and 'personObj(which created earlier)'. And generated accessors for them.
3.Created another class 'EmployerServiceDelegate' which has a method 'fetchListOfEmployees'. This method returns List<Employee>.
4.Now, created datacontrol using this class. And now in the datacontrol section ... i can see this method and its return value to use them over screen.
5.Now...created TaskFlow, PageFragment ... and did drag and drop the List<Employee> as a table and as a form.
6.On the form applied the partial trigger from table.
So,whenever user selects any row in the table ... the same data will be displayed in the below form. So far so good.
1.Now, i have used one of the operation on datacontrol i.e., 'Create' to create a new record.User needs to enter some data here. When user clicks on thsi create button, it is creating a row in the table and tried to create the form with empty fields.
2.*Here is the problem* : The data control was able to create the input field only for employeeId and not for the firstName,lastName.
Does any one of know what am i missing here. Thanks in advance !!

Parent child relation in OBIEE -RPD Issue

Hi,
I created a star schema by taking two tables . Now i want to establish parent-child relation ship .
Now by clicking create logical dimension ----->Dimension with parent-child hierarchy ,the member key is not found.Pls correct me where i went wrong .
Thanks-Bhaskar

I know you said you have primary key defined already but just to make sure, can you follow these steps:
1) Double click on dimension table
2) go to tab 'Keys'. check if your primary key is defined there.
3) If not, in 'Key Name', type in the key name
4) select the primary key(column) in 'Columns'.
5) Click OK.
and then try to create hierarchy by following these steps:
1) Right Click on the dimension table
2) Create Logical Dimension -> Dimension with Parent-Child Hierarchy...
3) Click OK (if you are OK with default values)

Why in case of parent child relation iterator fetching one duplicate record

Hi,
JDev Ver : 11.1.1.2.0
Technology : JPA/TopLik Service Facade Data Control (Without using BC4J)
I have created JPA/TopLink service facade from DB Tables and on facades I have crated DataControl which I have draged and droped on my screen to create input text, table etc.
In my application, I have many tables having one to many relationships. (Primarykey foreign key).
When I add more then one child columns (foreign key columns) for any one parent column (primary key column), in db its getting inserted properly but in iterator after refreshing also it showing one duplicate entry instead of actual entry.
e.g.
For one Account Id 1234 (primary key) , I am adding 3 account holders name (abc, xyz, pqr) in this case in db its inserting proper 3 entries but in iterator its showing
1234 abc
1234 xyz
1234 abc
so instead of pqr its again showing abc.
To select account holders name I have used selectManyShuttle components.
I have also tried tried dciter.refresh(DCIteratorBinding.RANGESIZE_UNLIMITED); to refresh iterator.
This is generic problem on most of the screen in my application where parent child relation comes.

You've been asked before on your previous questions (all of which still appear to be unanswered) to read the FAQ: {message:id=9360002} and post correct details of your question, and use {noformat}{noformat} tags to preserve your code/data formatting on the forum.
But still you post a question lacking all the information and formatting. If you can't be bothered to help us understand your issue (and read your code), why do you expect others will be bothered to try and help you?

Representating Hierarchical (Parent-Child) relation graphically using Swing

Hi,
I have to represent a hierarchical data which is having Parent-Child relation using Swing. I am not able to upload the image overhere, so I am represnting the data in such a way so that one can understand this problem. If anyone knows how to upload image on Sun forum, please let me know it will be great help for me.
Parent Root - A
Child of A - B, C, D
Child of C - E, F, G
Child of F - H
Child of D - J, K
The data needs to be represented in two formats-
1. Tabular Format
I am able to represent data in this format using combination of JTree and JTable. The data is getting represented in tabular format and I am able to expand and collapse the parent nodes to see the childs. The tabular data will look like below structure,
A
I_B
I
I_C
I I_E
I I
I I_F
| I |_H
| I
I I_G
I
I_D
I
I_J
I
I_K
2. Graphical Format
This is the other way in which I need to represent the data. The above shown tabular data needs to represented in graphical form. The end result should look like,
I A I
____________________I__________________________
___I___ __I__ __I__
I B I I C   I I D   I
____________________I____________ ______I________
___I___ __I__ __I__ __I__ ___I__
I E I I F   I I G   I I J   I I   K    I
__I___
I   H   I
Each box representing alphabates will be a component (like JPanel) which will have details about the item to be displayed. The parent and child should be connected with each other using line. This representation should be created at runtime using the hierarchical data. Also the parent and child relations should be expandable/collapsible as they are in JTree.
I am not able to find any component or any solution in Swing which can provide me this graphical representation. It will be great help if anyone can help me out in this.
Thanks in advance.

Sorry for inconvinience for the data representaion in graphical form. I don't know how this get jumblled. Please try to figure out the tabular/graphical representation using pen and paper as forum is not providing any help to upload an image.
Sorry again for inconvinience.
Thanks

How to delete parent child relation in Toplink

Hi All,
I have 3 tables A,B,C.
In Table A ,I am saving record.
Table B & C has parent child relation.
B-->Parent
C-->Child
So I want to save records in Table A.
And delete from child(C) 1st then from parent(B).
I m writing my code as,
em.getTransaction().begin();
em.persist(Table A);//save in Table A
em.remove(em.merge(Table B));//Remove from Parent
But how to delete records from child table then from parent table.
Thanks
Sandip

If you have a @OneToOne relationship between two entities, the join column information is used to order the SQL when you remove two entities. For example, if I have:
@Entity
public class Employee implements Serializable {
     @OneToOne
     @JoinColumn(name="ADDR_ID")
     private Address address;
...Then the following code runs regardless of the order of the remove calls.
          em.getTransaction().begin();
          Employee parent = new Employee();
          Address child = new Address();
          parent.setAddress(child);
          em.persist(parent);
          em.persist(child);
          em.getTransaction().commit();
          em.getTransaction().begin();
          parent = em.merge(parent);
          child = em.merge(child);
          // order of next two statements unimportant
          em.remove(parent);
          em.remove(child);
          em.getTransaction().commit();If I don't remove the parent and just the child I get the same error you do because of the FK from Employee to Address.

Parent Child relation in one transaction throws error... (

In nutshell, I have a parent->child relation ship in DB and due to the UI requirement, I created view link as Child->parent, it is giving a hack a lot of problems.... (it sounds silly but looks like I am loosing my mind over this)
Let me explain my situation,
- I have a table A with col-a and col-b. I have another table B with col-a (primary key) and col-c. (This way table A is a parent table)
- ON UI side i created relationship like table B is parent and Table A is child using col-a
- I need to create parent-child (one record for each) record programatically.........
I tried following thing:
- from backing bean, as soon as i create Table-B row first, i get error saying too many objects with same key (which is understandable because of table design..... and associaion must be throwing that error)
- from EOImpl file, it doesn't even find the child record being created... so during commit I can't send the foreign key value from Table-a to Table-b
Any suggestion is greatly appreciated?
Thank you,
-Raj

that depends on how you implement the multiple selection of orders.. you have to pass the selectedValues to the backend or store the values in a map or list and pass it..

Changing into parent-child relation

Hi,
I have a table which has the following fields and the table gives the identifier for parent-child relation:
ID
PARENT ID
structure
parentkey_field
foreignkey_field
Fields[]
data[]
1.ID is the numbering like 1,2,3...
2.PARENT ID will give the relation like which structure is the child for which structure.
Example: I have two structures HEADER and ITEM.Then the IDs will be 1 and 2.The parent id for ITEM will be 1(ID OF HEADER).
3.Structure is the header/item structure names.
4.parentkey_field and foreignkey_field are defining the header-child relation identifier fields.
5.fields[] is the table with all the fields of header and item.
6.DATA[] is the table having the data of header/item fields.
Now my requirement is to flatten this table into one more table(with field structure_name,fieldname,value) with parent-child relation.
Can anyone suggest something.

It would be better if you posted the code you tried first and then having others help you with what's wrong. Flattening a hierarchy is not that difficult; why don't you give it a shot first?

Inspection for Parent Child Relation

Hi
We are producing Mat.A from Mat .B and you want to copy the results from Mat.B .
Both materials are batch managed.
The requirement is - At the inspection for Material A , want to use batch derivation to copy results of Mat B (Parent Child Process)
Please Guide ..
Please schare Doc if available ..
Mayank MEHROTRA
Or in other words..
Whether its possible to transfer the characteristics values of the batch from parent materia (MOM Materials)l to Child Materials
Edited by: Mayank MEHROTRA on Jul 30, 2010 2:19 PM

Hi Mayank,
We had the same issue in one project. What we did, we develped a z- transaction and program for that.
We had child batches, for eg, 1234561,1234562,1234563,1234564. here the mother batch is 123456. so we recorded value for this mother batch in MSC1N. In developed z transaction, we had a field called "mother batch" and next two fields as "from child batch" and "to child batch". So make entry in these fields and execute. Data will be populated automatically.
Sit with a good ABAPer, he will be able to develop the same.

Creating View for a table with parent child relation in table

I need help creating a view. It is on a base table which is a metadata table.It is usinf parent child relationship. There are four types of objects, Job, Workflow, Dataflow and ABAP dataflow. Job would be the root parent everytime. I have saved all the jobs
of the project in another table TABLE_JOB with column name JOB_NAME. Query should iteratively start from the job and search all the child nodes and then display all child with the job name. Attached are the images of base table data and expected view data
and also the excel sheet with data.Picture 1 is the sample data in base table. Picture 2 is data in the view.

I think what you need is recursive CTE
Consider your table below
create table basetable
(PARENT_OBJ varchar(10),
PAREBT_OBJ_TYPE varchar(10),
DESCEN_OBJ varchar(10),DESCEN_OBJ_TYPE varchar(10))
INSERT basetable(PARENT_OBJ,PAREBT_OBJ_TYPE,DESCEN_OBJ,DESCEN_OBJ_TYPE)
VALUES('JOB_A','JOB','WF_1','WORKFLOW'),
('JOB_A','JOB','DF_1','DATAFLOW'),
('WF_1','WORKFLOW','DF_2','DATAFLOW'),
('DF_1','DATAFLOW','ADF_1','ADF'),
('JOB_B','JOB','WF_2','WORKFLOW'),
('JOB_B','JOB','WF_3','WORKFLOW'),
('WF_2','WORKFLOW','DF_3','DATAFLOW'),
('WF_3','WORKFLOW','DF_4','DATAFLOW'),
('DF_4','DATAFLOW','ADF_2','ADF')
ie first create a UDF like below to get hierarchy recursively
CREATE FUNCTION GetHierarchy
@Object varchar(10)
RETURNS @RESULTS table
PARENT_OBJ varchar(10),
DESCEN_OBJ varchar(10),
DESCEN_OBJ_TYPE varchar(10)
AS
BEGIN
;With CTE
AS
SELECT PARENT_OBJ,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM basetable
WHERE PARENT_OBJ = @Object
UNION ALL
SELECT b.PARENT_OBJ,b.DESCEN_OBJ,b.DESCEN_OBJ_TYPE
FROM CTE c
JOIN basetable b
ON b.PARENT_OBJ = c.DESCEN_OBJ
INSERT @RESULTS
SELECT @Object,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM CTE
OPTION (MAXRECURSION 0)
RETURN
END
Then you can invoke it as below
SELECT * FROM dbo.GetHierarchy('JOB_A')
Now you need to use this for every parent obj (start obj) in view
for that create view as below
CREATE VIEW vw_Table
AS
SELECT f.*
FROM (SELECT DISTINCT PARENT_OBJ FROM basetable r
WHERE NOT EXISTS (SELECT 1
FROM basetable WHERE DESCEN_OBJ = r.PARENT_OBJ)
)b
CROSS APPLY dbo.GetHierarchy(b.PARENT_OBJ) f
GO
This will make sure it will give full hieraracy for each start object
Now just call view as below and see the output
SELECT * FROM vw_table
Output
PARENT_OBJ DESCEN_OBJ DESCEN_OBJ_TYPE
JOB_A WF_1 WORKFLOW
JOB_A DF_1 DATAFLOW
JOB_A ADF_1 ADF
JOB_A DF_2 DATAFLOW
JOB_B WF_2 WORKFLOW
JOB_B WF_3 WORKFLOW
JOB_B DF_4 DATAFLOW
JOB_B ADF_2 ADF
JOB_B DF_3 DATAFLOW

Check Boxes in ALV (parent-child relation)

Hi Friends...
I am trying to display some data in ALV using the parent child relationship. I require the first field of the parent record to be a check box which is input enabled.
Whatever i tried the check box is not comming as the first field, instead it comes second after the key field (the link btw the parent and the child).
If anyone of you knows how to tackle the issue please help..
Thanks,
Derek

Parent Child relation SQL -

Hi all,
I am trying to write an sql - and the requirement is as below -
Table data contains columns Parent || Child || Summary_Flag
If Child is Parent again to some other Child then Summary Flag is "Y"
e.g. parent || Child || Summary_flag
P1 C1 N
P2 P3 Y
P3 C2 N
This relation exists to four level - .i.e. level to which child can be parent again.
I am trying to write SQL which will give me data in columns - i.e. Parent1||Parent2||Parent3||Parent4||Child.
Pleas help in any possible way.
thanks

ForEach iterator in parent child relation

Hi,
How can i use forEach to iterate parent child view object. Issue it is only able to fetch value of parent vo not child view object values, if I use af:iterator instead of af:forEach it works perfectly. So there is no issue with data.
But I am not able to iterate child VO.
<af:forEach items="#{bindings.testVO.rangeSet}"
var="parent" varStatus="parentRow" >
<af:outputText value="#{parent.Name}"/> -- it works fine prints value
<af:forEach items="#{parentRow.childVO.rangeSet}"
var="child" varStatus="childRow" >
<af:outputText value="#{child.subject}"/> ---> It doesn't work
</af:forEach>
</af:forEach>
If i use iterator it works fine... But I have to use forEach to generate dynamic id for each component in forEach Loop

I tried to use af:iterator first but the problem is it is not able to handle dynamic id generation for each component:
<af:iterator value="#{bindings.companyVO.collectionModel}"
var="company" varStatus="companyStatus"
rows="#{bindings.companyVO.rangeSize}">
<af:iterator value="#{company.employeeVO}"
var="employee" varStatus ="employeeStatus">
<af:outputLabel id="emp${companyStatus.index}${employeeStatus.index}" value="#{employeee.empId}"/> ->>> here id is always emp it is not able to get index value and if i used the same code in forLopp it works it is able to fetch dynamic id based on index like emp12 emp13 emp14 etc...
</af:iterator>
</af:iterator>

Hierarchy Parent Child Relation Storage

Hello All,
            I need to display hier. info in parent-child format. Any ideas on how to store parent child relationship in an ODS....I can view this format in the infoobject display screen for hierarchy...but cannot get this format to display..
EX: Parent - child1,2,3,4
      child1- child 1-1,1-2,...
      child2 - child 2-1,2-2...
thanks

Spanyal,
You will have to write a program to store this information in an ODS object. You will have to use /BIC/h<IO> Table to read the data and update a custom table. You will have to do some basic checks like business content or not, plan version, time dependency etc in the entry screen and then the program can read the hierarchy table in the format you want.
I am not aware of any simpler way to populate hierarchy data into an ods object in a meaningful fashion.

Parent-child relation

hi,
i create parent and child values for a segment in GL
how can i create a automatic calculation of the amount of all the child values for a parent value?
thanks a lot,
best regards

Hi
If you set up "Parent Child" Relationship in Oracle, the system will not sum up the child values at the parent level. However if you use the parent value in FSG the system will sum up the child values and show the same in FSG report.
If you want automatic summing up, you must use summary accounts and rollup groups feature in Oracle.
But I suggest that if you are using a small sized Chart of account (350-400 items), I suggest using parent child relationship since it is intutive.

Parent child relation using query

Hi,
If i pass one parameter as a parent.It will
retrieve all the child and subchild...
but it will be retrieved by one single query.
Is it possible?If possible pls give me an idea.
I got the inner most child using stored procedure and recursive fn.
But I couldnt get the child and subchild using
single query....
pls give an idea
below i gave table for example
Sno     Parent     Child
1     MD     GM
2     GM     Material manager
3     GM     Production manager
4     Production manager     Material staff
5     Material staff     production staff
6     production staff     Material student
7     Material student     production student
if i pass GM as a parent. it will retrieve
material manager and production manager...but it will be worked in single query
Thanks

Hi,
SELECT * FROM t11
START WITH parent='GM'
CONNECT BY PRIOR child=parent
Out put :-
2 GM Material manager
3 GM Production manager
4 Production manager Material staff
5 Material staff production staff
6 production staff Material student
7 Material student production student
