OIM API - How to get the values in the process form (both parent and child)

Hi,
I created an RO with a Process form (both Parent and Child).I created a unconditional process task which takes in the processinstance key and tried to retrieve the process form datas.When i tried to provison the resource,the process task is getting triggered and I could able to get the parent form data but not the child form data.
Any idea why is this happening?.Is it mandatory to have the "Triggers" ON to get the Child Form data.?
Thanks,

try this
tcResultSet childResults = formOper.getChildFormDefinition(
formOper.getProcessFormDefinitionKey(procInstanceKey),
formOper.getProcessFormVersion(procInstanceKey));
This should work,

How to delete parent and child records?

Hi friends,
I have a Master table and a child table.
The Child table got reference key with the master table without on delete cascade.
Now, I want to delete the Master records and also it's corresponding child records.
How to do?
Thanks in adv,
regards,
Vijay

Delete the records from the child, then delete the records from the parent in two separate delete statements. I'd prefer that you create a stored procedure that does both steps.

How to delete parent and child records together ?

Hi,
I'm using Jdeveloper 11.1.2.2
I want to delete a row from a table but it is showing: Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-02292: integrity constraint (TABLE1_TL_FK1) violated - child record found.So how can I delete a Child row and table row in one method ?
I cannot access the child's VO because it is not added to the AM.
Thanks,
Nigel.

John, as usually, is right with the pointer to the documentation he pasted. Just to make sure you read it carefully, let me hoghlight an important point here:
"If the option is selected, then the composed entities do not perform the DELETE statement *on the assumption that the database ON DELETE CASCADE constraint will handle the deletion of the corresponding rows*."
So make sure the database is setup for cascade delete as otherwise you still will not succeed

Just use a format like this:
http://<Server Name>:<port Number>/OpenDocument/opendoc/openDocument.jsp?sDocName=reportB&sType=wid&sRefresh=Y
&lsMObjectName=[test1],[test2]
Here in lsM[ObjectName] parameter [ObjectName] = the object name which you want to send data to ReportB
I can give you a idea of creating hyperlink for jumping another report (Here ReportB)
Just use a formula like that in any cell:
="<a href=http://<Server Name>:<port Number>/OpenDocument/opendoc/openDocument.jsp?sDocName=reportB&sType=wid&sRefresh=Y&lsMObjectName=[test1],[test2]&sWIndow=New> Click here to view </a>
Now from the property select Read cell content as "Hyperlink"...
thats it......
For more information please see the
"OpenDocument" artile
Hope you can get help from this

Check for same parent and child combination

hi all i am using oracle 10g. can you please help me in this issue.
how do i know if the same combination of parent and child present in the table
key value and value are the values given by user.
if the user try to create a same profile with same set of key_value and value then that should be avoided
so how to achieve that.
example profile already in the table
-- PROFILE_ID,DETAIL_ID,PARENT_DETAIL_ID,KEY_VALUE, VALUE, LAST_IND

Session expiration issue with parent and child window

Hi,
We have two applications (App1 - Implemented using JSF, Spring and Hibernate and App2 -Implemented using Spring MVC, Spring JDBC).
I have implemented 'Test Access Content' functionality in App1.
First admin user (Role- Manager) needs to login to App1
As part of 'Test Access Content' functionality, he enters URL with encrypted key and click 'Test Access' button.
It opens new window (implemented using java script - window.open) and hits spring controller of App2.
In spring controller of App2, I am decrypting the key to get user details. After that i am setting user details in session, constructing final URL to display actual content.
Problem is parent window maintains session till child window renders response. Once child window renders response, parent window loosing session.
So, if i click any button in parent window after child window renders response, it displays login page as there is no session for parent window.
Please note that App1 and App2 are sharing same domain. only context paths are different for both apps (app1 and app2).
Any suggestions on this issue are much appreciated. Please let us know if you have any questions.

Hi,
When you open a child window from parent window then you can access child data in the parent window through javascript.
We have a main web page. There are quite many links on it from which >user can open new web pages but the data is saved when the submit >button on the main page is clicked. Also data that user entered on the >other sub pages is not displayed in the main window.
1 is this a case of parent and child window.case 1 When you are submitting the main page you need to run javascript function and get data from child windows and save that to database or session. next time when you are displaying the main window you need to query session or database to display the child window data in the main window.
Case 2> closing child window and you need data in the parent. This can be done in two ways.
1> When you are closing the child window populate some variables of the main window using javasript.
2> Save the values in the database or session and refresh the main window and extract data from database or session
Where should the data be saved that user enetered on the sub pages as the data is not shown in the main page - should it be stored in the session?It is design decision. You can store data in either session or database when you are closing the child window. But ifyou are saving the data on the main page then you can populate main page with child windows data using javascript. Save the data t database when main window data is saved. Depends on business requirements.
In short if you are saving child windows data in session or database then you need to refresh main screen to pull that data otherwise populate main screen using javascript.
I hope i answered your questions :) best of luck

Insert data Flatfile table to Parent and child tables

Hi All,
I have Flatfile table which is we getting from daily txt files and i want to populate flatfile data to parent as well as child tables. parent table has primary key as ID. This ID is foreign key of child tables.
Here i have mentioned our process.
1. Flatfile duplicates has to remove with condition of daily date.
2. Before Insert parent table have to check duplicate(we have Unique key of 4 columns in parent) if duplicate is there we have to delete duplicate then Insert into parent table unique records(Primary key is ID).(here why we are delete duplicate record meaning
we getting daily files so if any records updated in future that record should be insert to parent and child table so only we delete old records and insert new records).
3.After insert parent we have to populate child tables from Flatfile table as well as we have to insert parent table primary key as foreign key of child tables.
4. if any truncation error occurs that errors should go to error log table.
Right now we are using cursor for this concept and cursor has performance issue. so we are trying to optimize other way to populate parent and child table to increase performance to populate.
Please help us to which way to do this process increase of performance .
Please can any one reply.

Merge of parent and child content of a heirarchy

Can anyone say the procedure to of merging the parent and child link of heirarchy into one string and been displayed in a seperate feild

Lakshmi Kanth,
I am <b>assuming</b> that you are refering to "Merge Records" option in MDM Data Manager. If this is the scenario that you are looking for then here are the details:
When it comes to Hierarchy tables, merging records is different than Merging Main table records. This option in Hierarchy tables also has lot of constraints - One of them is "Destination and source node cannot have children". Because of this, currently it is not possible to merge Parent- child records. However, for more information, please refer to this <a href="http://help.sap.com/saphelp_mdmgds55/helpdata/EN/43/9967ab46ec60b7e10000000a11466f/content.htm">link</a> for more information on Merging in Hierarchy tables.
If "Merge Records" in Data Manager is not the option that you are looking for, let us know more details.

Rajani Kumar

How to differentiate between Parent and Child in IBASE?

Hi. I am working on enhancing a BAPI :BAPI_GOODSMVT_CREATE by calling the following function module IBPP_CREATE_IBASE at its exit.
The BAPI is being called from an SAP ME system and will be passing MATNR and Serial Number of Parent and Child materials to create the IBASE in ECC system. I am confused as to how to differentiate between whether a object is Parent or a Child when the BAPI: BAPI_GOODSMVT_CREATE is called.

if you have NULL valued fields. If
you do a compare and one or both are NULL, then the result is always NULL,
never true or false. Even comparing two fields which are both NULL will
give NULL as result, not true! Or if you have something like "select
sum(field) from ..." and one or more are NULL, then the result will be
NULL. Use always "if field is NULL ..." for NULL checking and for safety
maybe something like "select sum( IsNull(field,0) ) from ...". Check the
function ISNULL() in the manual.

How to update parent and child tables while updating parent table

I have a parent table EMPLOYEE which includes columns (sysid, serviceno,employeename...) sysid is Primary key, serviceno is Unique key and I have child table DEPENDENT includes columns (sysid,employee_sysid,name,dob...) here again SYSID is primary key for DEPENDENTS table, employee_sysid is Foreign key of EMPLOYEE table.
Now I want to change SYSID (using sequence) in EMPLOYEE table which need to be update in DEPENDENTS table as well
Note: I have 10000 records in EMPLOYEE table as well as I have 5 more child tables which need to update new SYSID.
please help me

first disable the FOREIGN KEY Constraints.
you can update Parent as well as Child record also with help of trigger.
here i am giving you one examlpe..it may help u.

create table child_1(id number primary key,p_id number,dob date,
CONSTRAINT FK_id FOREIGN KEY (p_id) REFERENCES parent (ID))
create table child_2(id number primary key,p_id2 number,addr varchar2(1000),
CONSTRAINT FK_id2 FOREIGN KEY (p_id2) REFERENCES parent (ID))
insert some test data to parent and child tables.
alter table child_2 disable constraint FK_id2
alter table child_1 disable constraint FK_id2
CREATE OR REPLACE TRIGGER delete_child
BEFORE UPDATE ON parent
FOR EACH ROW
