Eg. Supplier A in Australia has Supplier Sites X in Melbourne and Y in Sydney.
      Supplier B in US has Supplier Sites C in New York and D in California.
I need to have Search, based on two fields Supplier Name and Country
Let us assume i am searching with Supplier Name A then the page should be in the below layout
Query Region
Supplier Name : A
Country:
Master
Supplier Name Country
A                     Australia
Detail
Supplier Site City
X                   Melbourne
Y                   Sydney
In detail VO it should allow me to add new sites which means i need to connect this VO to database to insert new records
I have gone few threads and understood that this can be achieved by creating SupplierVO, SupplierSiteVO and a ViewLink.
But when tried i don't know how can i relate my query region with the Suppleir Table(Header Reagin and Table Using Wizard) and Supplier Site Table(Header Region and Table Using Wizard) i am not sure if i am correct or not, please advise
2. Also i need to have a Open button in this page and if click the button it should navigate to some other page.

How can I create master detail reprot output

Hi to all!
I have one question about creating master-detail report.
My report must show asset's and depreciation and all other information for that asset. I can have one asset at two or more locations, cost numbers, ...
Now I have 2 SQL's in my XML file. Q1 is master data for some asset and Q2 is detail for that asset, if I run my report with all parameters (book type, asset nubmer, cost nubmer) then it runs OK (I get master-detail report, for each asset I get separate page, even if asset has multiple cost number or locations), but if I run that report without cost number parameter I get multiple pages for master (data from Q1 on each page), but detail data is all together on each page.
Can you help me how can I also get separate detail data in that case?
I hope we understand each other!
Regards,

Hi Mustafa,
Thanks for ur response.
Actually, In my first tab page I have some details of employ which is based on a database table.
The second tab page also contain the details of employ which based on backend stored procedure. I used a REF cursor in that stored procedure.
When I have created a master detail relationship based on employee_id, it created the relationship but while executing the form it is giving error like
'pk_empdetails.query' must be declared.
pk_empdetails.query(is backend procedure).
Hope u got my point.

Help needed to create a master-detail JSP page using OAF.

I like to create a master-detail JSP page using OAF. If any help or guide will be appreciate.
- Kausik

A Master Detail Page is a basically a game between two VOs(Master and Detail mostly connected through a View Link). You can also have a look at the View Link section in the Dev guide. Page Layouts is one thing which you can take a call yourself.

Unable to create master detail report

Hi,
I´ve two tables (Organisation and Purchases) and want to create a master-deatil with the wizard.
At the end an error occurs:
ORA-20001: Unable to create master detail page. ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Unable to create Master Detail pages.
Return to application.
Any ideas ? Any reaction will be appreciated

Leo,
How are your two tables related? Do you have a foreign key constraint? It sounds like that there may be a datatype mismatch between the master table's PK and the detail table's FK - check to make sure that they are both NUMBER.
Thanks,

Creating master-detail VO in custom AppModule method

Hi.
I need to create master-detail view objects and save them in DB in my custom AppModule Service Interface method.
I have the next master-detail view objects:
RegistryVO (1) -- (*) RegistryItemVO
Also I have a view link for this relationship.
I wrote custom method with next signature:
Integer createRegistry(RegistryVORowImpl registry) {
Then, I added this method to my AppModule Service Interface.
Method works fine, but only master row is created and inserted to DB (only Registry but not RegistryItem). I.e. when I testing this method in EM I fill full RegistryVO with nested RegistryItemVO data but in my method RegistryVO comes without nested RegistryItemVOs.
Then, I added SERVICE_PROCESS_CHILDREN custom property to view link (RegistryVO-RegistryItemVO) as it described in chapter 11.2.5 of Fusion Developer 's Guide for Oracle Application Development.
After that nested RegisttryVO in my method contains nested RegistryItemVOs.
In my custom method i need to set primary key for RegistryVO. So I set it in registryVO to PK attribute and set it in nested registryItems to FK attribute.
But when I doing commit I have an exception:
Exception while executing the business logic: JBO-26048: Constraint "PP_PST_RG_IT_PP_PST_FK" is violated during post operation "Insert" using SQL stat
ement " *INSERT INTO PP_PERSON_ST_RG_ITEM* (PP_PERSON_ST_RG_ITEM_ID,IN_DOCUMENT_ID,POL,FULLNAME,NAME,FULLOT,TIN,D_ROG_DT,D_REEST
_DT,PROCESSING_DT,PROCESSING_STATE_CD,RECEIVE_YEAR) VALUES (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11,:12)".: ORA-02291: integrity
constraint (PP_PST_RG_IT_PP_PST_FK) violated - parent key not found
It seems that only registryItems are commited in DB. I'm not seeing INSERT for Registry in ServieInterface log...
But if I setting primary key for RegistryVO when I invoking method (if I setting id for registry in test console of EM, not in method) - it's work fine .
What I'm doing wrong ?
How can I create custom method for AppModule Service Interface to create master-detail view objects and set PK for master and FK for details within method ?

Thanks for reply, John.
I have already added master and detail view objects usages to my AppModule Data Model. And yes, I add detail VO as child of master.
It seems that the reason of my problem is another...
I can't create master/detail when I'm setting id of master in custom method. If I set id of master in input parameter (RegisterVORowImpl) then method invokes successfull.
I noted one moment - if I'm not setting SERVICE_PROCESS_CHILDREN custom property for view link, I can set id of master VO inside method. But in this case my master VO haven't got nested RegisterItemVOs.

Error creating Master/Detail Form

Hi,
I tried to create a master detail form. I went through all the steps fine, only when i click the button to create the form, i received the following errors:
ORA-20001: Unable to create master detail page. ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Unable to create Master Detail pages.
Could someone please tell me what's wrong?
Thanks,
Patrick.

We are getting this message in several areas in the development environmnet. It's happening in the developer login screen, when creating new tabs, and when tryig to create master detail reports. Here is our error from the Apache Log:
[Mon Mar 2 11:41:31 2009] [error] [client 10.64.8.231] [ecid: 1236012090:148.94.143.136:24226:0:1621,0] mod_plsql: /pls/apex_qmnt/wwv_flow.accept HTTP-404 ORA-06502: PL/SQL: numeric or value error\nORA-06512: at line 31\n
I think this is different from the issue above as that is due to too many items in a shuttle list. Ours seems to be related to our new APEX insstallation. Any help is appreciated here.

How to implement Master-Detail Search in TopLink without using DataControl

Hi,
I am using TopLink and EJB in our requirement. But we are not creating any data controls. Without data controls how to implement master detail search using TopLink and EJB. I did search for a single table. It is working fine. The way i implented is as follows.
1) Taking search parameter from UI and passing it to A delegator class's method.
2) Delegator class's method calls the EJB's NamedQuery which i already created using expression builder.
3) EJB executes the NamedQuery with the parameter we are passing. And it returns the results back to UI.
But as i am new to TopLink, can anyone tell me the procedure to implement Master - Detail search. Here we need to search based on Master table's column.
Waiting for the replies regarding this.
Thanks & Regards,
Suresh Kethireddy

Hi,
I did it successfully. Following is the code.
Session session = getSessionFactory().acquireSession();
UnitOfWork uow = session.acquireUnitOfWork();
ReadAllQuery raq = new ReadAllQuery();
Dept d = new Dept();
d.setLoc(loc);
raq.setExampleObject(d);
List<Dept> res=(List<Dept>)uow.executeQuery(raq);
for(int i=0; i<res.size();i++){
System.out.println("Dept DeptNo ---"+res.get(i).getDeptno());
System.out.println("Dept DeptName ---"+res.get(i).getDname());
System.out.println("Dept Location ---"+res.get(i).getLoc());
List<Emp> eRes=res.get(i).getEmpCollection();
for(int j=0; j<eRes.size();j++){
System.out.println(" Emp No ---"+eRes.get(j).getEmpno());
System.out.println(" Emp Name ---"+eRes.get(j).getEname());
System.out.println("Emp HireDate ---"+eRes.get(j).getHiredate());
System.out.println(" Emp Job ---"+eRes.get(j).getJob());
System.out.println(" Emp Mgr ---"+eRes.get(j).getMgr());
System.out.println(" Emp Sal ---"+eRes.get(j).getSal());
But now my question is, i want to search by providing Dept param as well Emp(Which is child table) param also. Is it possible?
I tried in 2 ways like this.
1) Emp emp = new Emp();
emp.setEname(eName);
dept.addEmp(emp);
raq.setExampleObject(dept);
2) Emp e = new Emp();
e.setEname("ADAMS");
List<Emp> list = new ArrayList();
list.add(e);
d.setEmpCollection(list);
raq.setExampleObject(d);
But in both cases i failed to search based on the values i am passing to Emp.
Is there any other way to achieve my requirement?
Any help on this is great.
Thanks & Regards,
Suresh K

Developer Mode Error: Stale Data -- Master Detail OAF Page

Dear Members,
I have created a simple master detail OAF Page by following the below steps:-
1/ Created a MasterEO
2/ Created a DetailEO
3/ Created a MasterDetailAO
4/ Created a MasterVO based on MasterEO
5/ Created a DetailVO based on DetailEO
6/ Created a MasterDetailVL (view link) based on MasterDetailAO
7/ Created an AM
7/ Attached the MasterVO and MasterDetailVL to the AM
8/ Created a simple Master Detail Page in which user can enter the master and detail records. After entering the details user can click on the save button.
Code in AM_
public void createHeader()

OAViewObject vo = getMasterVO1();
if (vo.getFetchedRowCount() == 0)
+{+
vo.setMaxFetchSize(0);
+}+
Row row = vo.createRow();

am.invokeMethod("createHeader");
am.invokeMethod("createLines");
I am facing the below error when trying to save the master detail records in the respective OAF Page_
Developer Mode Error: Stale Data_
The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example). If the browser's navigation buttons were not used, this error could have been caused by coding mistakes in application code. Please check Supporting the Browser Back Button developer guide - View Object Primary Key Comparison section to review the primary causes of this error and correct the coding mistakes.
Cause:
The number of displayed records, 1, exceeds the actual number of records, 0, in view object AstfAM.DetailVO1. Some of the displayed records may have been deleted.
To proceed, please select the Home link at the top of the application page to return to the main menu. Then, access this page again using the application's navigation controls (menu, links, and so on) instead of using the browser's navigation controls like Back and Forward.
I request the members to help me in resolving the above error.
Many thanks in advance.
Regards,
R4S.

Hi user11991972,
I just faced the same issue and I managed to fixed it using this thread:
Developer Mode Error: Stale Data
In my case, I amended the "Change indicator" checkbox on some of EO attributes.
One of the master attributes was updated by the AM from the detail page, but when navigating back, the master page was not refreshed due to a customer requirement.
But I wonder if it could be of any help in your case...

Olivier
