HELP FORM MASTER/DETAIL!!!

Hi,
i created a form master/detail, when i click "add row" in detail form after entering all required values oracle give me this error:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "A884FA378C851786DDFE3A33709CB23C", item checksum = "1697D9A1AD2F3544A697435A5FC09104"., update "DS"."TARIFF_PAX" set "ID_TARIFF" = :b1, "PAX" = :b2, "RATE_PAX" = :b3, "LEVEL_PAX" = :b4
Could someone help me?
Thanks

All it means is that you perhaps skipped selecting the columns for the detail table when creating the form.
Try creating again and this time select the columns appropriately for Master as well as Detail tables.
Regards
PS: Always mention the basic information like Apex version, DB version, etc

Hi,
I tested it on JDev12c and also works:
Couple of tips:
- Try to keep your payload as small as possible. Check this post: http://avioconsulting.com/blog/decoupling-oracle-bpm-process-instance-information If you put all your information on XML is like you have two databases and is annoying to keep them sync.
- if you decouple your data, you will be able your UIs, so you could create an ADF app with bounded taskflows (e.g.: Master-Detail) and embed it on your ADF-HumanTask app.
Hope this helps,
Jorge

You have master - detail relationship here. So unless you click on second employee it won't show you salary for second employee.
You can create a control block and capture values in this block through cursor. You can also create a view and get values from view. In both cases you need only one block not two.
Are you showing this only for display or user can also modify these values?

Oracle Forms : Master Detail : Cannot query detail block

MY requirement is: when user enters records in master block, the corresponding records should be displayed in the detail block. (Detail block is just for viewing).
Master block is a database block based on a custom table. All fields are enetereble in this block.
Detail block is a a database block based on view which is built joining the custom table(on which master block is built) & a standard table. None of the fields in detail block are editable. they are just display only. For detail block, set the Key Mode=Non-Updatable, Enabled a field as Primary Key.
I have created a relation between the 2 blocks. (Deferred=No, AutoQuery=No, Delete Record Behaviour=Isolated.). There is a join between master table & this view.
But when I enter record in master block & save. the detail block records are not displayed. (Message : No Navigable Items in Detail Block).
Yes, there are no navigable items in detail block, because its just for viewing purpose. How can this be achieved.
Thanks,
Naveen

Thanks for your inputs. I got the solution for this. Earlier all items in the block were DISPLAY_ONLY. Now, I have selected them as TEXT_ITEMS (even though they are not updatable). It is working fine now. Thanks.

Wizard based forms Master-Detail

I was wondering how I could used the Browse/Edit forms generated by the wizards for BC4J-JSP and UIX-JSP pages to create a "tabbed page" Mater-Detail type application.
Suppose I have a PurchaseOrderMaster (POM) vo and a PurchaseOrderDetail (POD) vo. The wizard generates me two pages. Now if I remove the POD link on main.jsp/main.xml and create a link on the POM.jsp how would I browse/edit only the rows for the active POM.jsp on the POD.jsp? I'm thinking I would like POD.jsp to look/act similar to the FkDeptnoLink page that is generated by the wizards for the scott schema. Hmmm maybe, maybe not.
It seems like passing the POM.jsp current row data (like PO_NUMBER that is the FK in POD to POM) is the answer but I'm just too new to this J2EE stuff to "gleen" from the documentation on how to do that. Can anyone provide or point me to explicit exapmples of this type of activity?
TIA,
Ed.

Found it in the How To's.

More than one Detail table in the Master Detail forms!

Hi,
I need to have more than one Detail table in Master Detail Forms.
I want to see the details of the rows of the first Detail table in the Second Detail table. Please guide me to do this.
Sincerely yours,
Mozhdeh

You can do one of two things
1) Depends on the nature of your data model. I was able to manage many to many
relationships using views and instead of triggers. This solution is somewhat complex but can work in certain situations.
2)Works for situations where master record exists. create a page with mulitple portlets syncronized on some related key.
create the following package to use on the md forms to place on the one page to be rendered.
-- this package will facilitate the storage and retrieval of keys used by the related forms.
create or replace package session_var
IS
session_parms portal30.wwsto_api_session;
g_domain varchar2(2000) := portal30.wwctx_api.get_user;
function get_id (id in varchar2) return number;
PROCEDURE SET_ID
(ID in VARCHAR2
,p_val in VARCHAR2
,P_URL in VARCHAR2
END SESSION_VAR;
create or replace package body session_var
IS
--pkg body
function get_id(id in varchar2) return number is
l_store_session portal30.wwsto_api_session;
l_id number;
begin
l_store_session := portal30.wwsto_api_session.load_session(
p_domain => session_var.g_domain,
p_sub_domain => 'your domain');
l_id := l_store_session.get_attribute_as_varchar2( p_name => id);
return l_id;
end get_id;
PROCEDURE SET_ID
(ID in VARCHAR2
,p_val in VARCHAR2
,P_URL in VARCHAR2
IS
l_store_session portal30.wwsto_api_session;
begin
l_store_session := portal30.wwsto_api_session.load_session(
p_domain => session_var.g_domain,
p_sub_domain => 'your domain');
l_store_session.set_attribute(
p_name => id,
p_value => p_val );
l_store_session.save_session;
* Redirect to the page using p_url;
portal30.wwv_redirect.url(P_URL);
end set_id;
END SESSION_VAR;
--the form master detail form, section before display page enter the following code and publish as portlet.
declare
l_fs varchar2(4000);
l_s varchar2(4000);
v_con_id number;
begin
v_con_id :=rfq.session_var.get_id('CON_ID'); -- primary key and key used to relate details
p_session.set_shadow_value( p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'A_CON_ID', -- attribute on form related to primary key
p_value => '= '|| v_con_id,
p_language => portal30.wwctx_api.get_nls_language ,
p_index => 1
l_fs := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK', p_attribute_name => '_FORM_STATE');
l_s := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK', p_attribute_name => '_STATUS');
if l_fs = 'SAVE' and l_s is null then
WWV_MASTER_GENSYS_1(p_block_name => p_block_name,
p_object_name => p_object_name,
p_instance => p_instance,
p_event_type => p_event_type,
p_user_args => p_user_args,
p_session => p_session);
p_session.save_session;
end if;
if l_fs = 'QUERY_AND_SAVE' and l_s is null then
WWV_MASTER_GENSYS_1(p_block_name => p_block_name,
p_object_name => p_object_name,
p_instance => p_instance,
p_event_type => p_event_type,
p_user_args => p_user_args,
p_session => p_session);
p_session.save_session;
end if;
exception
when others then
PORTAL30.wwerr_api_error.add(PORTAL30.wwerr_api_error.DOMAIN_WWV,'app','generic','onLink', p1 => sqlerrm);
raise;
end;
--then create other md forms and publish as portlets in a similar manner.
-- create a form (form_session_vars) to call procedure session_vars and place the following code in the
addiontional pl/sql tab
WWV_GENSYS_1(
p_block_name => p_block_name ,
p_object_name => p_object_name,
p_instance => p_instance ,
p_event_type => p_event_type ,
p_user_args => p_user_args ,
p_session => p_session);
--then create a page and place the md forms created above as portlets on the page.
--create a link and target the form_session_vars and in the link target inputs
enter the values for your user parameters
id= CON_ID --"your primary key name"
p_url= url/page/"your_page"
--finally create a report (QBE or standard).
in the column formation section use the link created earlier to direct the user to the target page.
How it works.
When the link is selected the form_session_Var is called and automatically runs setting the primary key values
in the user session store. The step is required or the resulting page will not render properly. Then the user is redirected to the page where the portlets are rendered. The portlets start rendering, the before display page calls the session vars package to retrieve the key and put the form into query_update mode returning the data.
The portlets finish in query_and_save mode with details in update mode, the allowable insert, delete and none actions will be available for the details.
benefits: The session_Var package code is resuable as well as the form form_session_Var and the link. passing the key name and values are done at the report level and detailed in the report links. the md forms will need to reference their related keys.

Can't add new detail record in Master Detail form

Hi ,
I've created a simple database application from scratch by initially selecting a Master Detail page. This generated a report page (for the parent ) and a form page (for the child ). On using the form to add a new child record the following error was generated:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-01400: cannot insert NULL into ("STUDENT1"."DELEGATE"."DELEGATE_ID"), insert into "STUDENT1"."DELEGATE" ( "DELEGATE_ID", "CLIENT_ID", "SURNAME", "INITIALS", "SEX", "SPECIAL_NEEDS") values ( :b1, :b2, :b3, :b4, :b5, :b6)
Error Unable to process update.
The 'child' field listed in the error message is automatically hidden on the form and I had presumed that on generating this form using the wizard that I would have had an opportunity to link the delegate_id field to a trigger or a sequence as seems to happen when creating a database application scratch using other page types. I'm new to Apex so I'd be grateful if anyone could let me know as to why this default behaviour occurs,
regards,
Kevin.

I tried it for Apex 4.0.2 (my version) and 4.1 (on apex.oracle.com) and I am asked for master and detail PK generation in both versions.
What are your steps exactly in the wizard? Like this?
Create page -> Form -> Master Detail Form
Now you see a whole list of sub steps including "Primary Key Source".
Oh I see "Create Application wizard." in your post. Start with an empty application (blank page) and use the Create Page wizard instead. Maybe that's the difference.

Change primary key field in Master-Detail Form (Urgent)

Hi,
Can some experts share your valuable experience on the problem below?
We have created a form Master-Detail relation. For some reasons, we have to allow the primary key field to be editable. But we couln't achieve it in Form 6i. It gives update error during commit.
Your kind help will be highly appreciated.
Regards,
YM

Hi there,
I think the problem is because u are updating the primary key in the master block but since it is a master detail block u need to update it in the detail block as well.so what i suggest u to do is in the pre-insert trigger assign the value of master primarykey to the detail primary key....
just check this out hopefully this shud help u.
Bye

Master detail report/form FK problem

Anyone...anybody!!!
I'm using APEX 4.0.1... and Oracle 10g.
I have two tables that are linked with FK in the detail table
Master table
ID_ENDURGR     NUMBER --PK populated with a trigger
KT_UMSAEKJANDI     VARCHAR2(10 BYTE)
TIMABIL     NUMBER
NUMER_UMSOKN     NUMBER
HEILDARKOSTNADUR     NUMBER
Detail table
ID_EIGENDUR     NUMBER --PK populated with a trigger
KENNITALA     VARCHAR2(10 BYTE)
EIGNARHLUTI     NUMBER
KOSTNADUR_VINNA     NUMBER
ENDURGR_ID_FK     NUMBER -- FK on ID_ENDURGR in the master table
If I create a application with a master detail page using the wizard, pages with a report and a tabular form are created. This works fine and the FK field in the detail table is automatically populated with the PK from the master table.
If I create an application with a blank page an on that page create a region > form > master detail > same tables >use existing triggers > default > Edit detail on separate page ... three new pages are created: Report, master form and a detail form.
If I create a new detail record with this application the FK field is not automatically populated.
Why? What am I doing wrong?
The trigger on the detail table:
create or replace
TRIGGER "bi_RSK_541_EIGENDUR"
before insert on "RSK_1018_EIGENDUR"
for each row
begin
if :new."ID_EIGENDUR" is null then
select "RSK_541_EIGENDUR_SEQ".nextval into :new."ID_EIGENDUR" from dual;
end if;
end;
Do I need to add something here... or what?
Please help.

Master-Detail and Master-Detail2 forms, elementary approach, needed

For showing on one form 1 master and two details tables (all updatable)
On one form, MRU, MRD Data manipulation processes are not possible, so manual approach is needed (AFAIK).
How to implment this...where to read.
THX!

Well, I have serious doubt for long questions...so I try to short as possible.
I have Form Master detail created through Wizzard. I want to add another table which is also 1:m detail from the same master.
I have succesed making second report (based on query) but it is not updatable. Deletion is don in For update and insert I have use aother page.
I want some instructions how to implement this feature on one form regerding MRU is not possible to implement on one page for different tables.
Just 10 sentences how to make such a thing. It will be nice to hear that this and this is not good for that and that reson and the best way should be do in this way..
OK!?

Master Detail - Detail parent child relationship

Hello All,
I have a setup where I have 3 tables. Call them A, B, and C. Table A is the parent table to the child table B. Also table B is the parent table to the Child table C. Is there a way to represent this in Apex? So far I have created two Master Detail forms: Master Detail form one has the relationship A+B and Master Detail form two has the relationship B+C. Can Apex support a Master Detail Detail form.
Also, is there a way to have my detail page editable without linking to another page to save and update?
Please let me know what everyone thinks.
Thanks
Ryan

Hi,
You can google it - so much information is available online. Any how
Parent Child relationship
PK FKBasic example - Parent and Child in real life -similarly the Table_A is having relation with some other Table_B.
Example
Table_A
columns :-
Student_No, Student Name, Student_address
Now the Table_B store the assignment details
Student_No, Subject_1,subject_2, subject_3
Now relation of join is Table_A.Student_No = Table_B.Student_No
With out the TAble_A details -can be identified the Sudent details etc., No - It's Master data - which is not dependent on any other table and Column Student_No- Acts Primary Key which is Unique -through which we can identify a specific details of particular student. Now comes to Table_B - with out the student_No - we can't say whose details of assignments belongs to whom - now the student_No in Table_B is dependent on some other table - now this table acts a child and Primary Key of Table_A acts Foreign Key - that column helps to identify the record.
Master Detail
Reference tablesconcept of understanding is same when - when comes c,c++, java and c sharp - acts the same but inheritance, interfaces, polymorphisms and overloading code of language differs. If you go further j2ee differs

3 Page Master Detail Wizard

Using the Create Page wizard to create a 3 Page Master Detail by selecting the "Edit detail on a separate page. Resulting pages are:-
1. Report on Master page,
2. Master Detail page (allows maintenance of Master row)
3. Maintain Detail page
However the linkage between the Master Detail and Maintain Detail pages are suspect along with the resulting Maintain Detail page.
On Master Detail page, displaying an existing master row, the user wants to create a detail row - pressing the [Create] button for the detail does navigate to the Maintain Detail page BUT it does not pass the primary key ID value of the Master row which was displayed.
Also when the user presses the edit details from the Master Details page then why should the displayed detail's lookup master primary key value ID updateable, if APEX is shielding the users/developers from the alleged problems of natural keys and leaning (supporting) surrogate keys then why is the detail's master key value ID updateable?
Also is there any examples out there which show the best way to implement Master with many details and also Master > Detail And Detail of the Detail. In the tutorials we are only exposed to simple data models that only have one level of details.
Thanks

Hi,
I am using the Create Page wizard, specifically the Form, Master Detail with Edit detail on separate page (as opposed to edit details on same page as master using a column report) to create a "3 Page Master Detail" as per wizard feedback.
Take for example the table Suppliers (master) and Supplier_Contacts (details) as a simple example.
Page 1 - Lists Suppliers as a column report on the Suppliers table with an edit icon on the P1_SUPPLIER_ID page item. Pressing edit icon will navigate to page 2 passing the P1_SUPPLIER_ID value as a parameter. Pressing the create icon will also navigate to page 2 but will not pass a P1_SUPPLIER_ID value.
Page 2 - Supplier & Contacts (Master Detail) page, permits edit (insert, update and delete) of Suppliers (master) and also displays the Supplier_Contacts (details) rows for the supplier_id of currently displayed suppliers row. The displayed Supplier_Contracts have an edit icon that will navigate to page 3 passing the supplier_id and contact_id for the selected supplier_contacts row. Also has a create button on the detail Supplier_Contracts region which will navigate to page 3 BUT the wizard has not passed the P2_SUPPLIER_ID value as a parameter as the data model and user action dictates.
Page 3 - Supplier Contacts (edit details on a separate page). My observation is that the Supplier_ID (foreign key to Master Suppliers table) is displayed as text item and is updateable when navigated from page 2 as an edit details transaction/event. Why on earth allow a user to select and navigate the Supplier and then the Contact to edit and then allow the user to update the master foreign key? Similarly if the user has selected and navigated to the Supplier (master) to which they wish to add a Supplier Contact (detail) why is the supplier_id (master PK ID) not passed to the edit details page and the supplier_id also non-updateable.
Hope this explains it a bit better.

Master/Detail report on same page.

Hi, I am trying to put together a report (10g HTML DB) and can't seem to put together a master/detail report.
I would like to have a header, something like
Project Title -- Project Status etc... for each project. Then below this section
Project Detail 1
Project Detail 2
Project Detail 3
Loop through the projects
It's just two tables. projects and details. Details has a fk project.id.
I tried to do a Form -> Master Detail but it puts them on seperate pages and also allows the data to be edited. I don't need that, this is simply for display.
This is something I can put together just creating an html table in an anonymous PLSQL block but if ability is there in HTML DB I should probably try it that way.

Hi,
This can be achieved by doing something like the following:
Have a single SQL statement that joins the two tables together. eg,
select p.project_title,
d.project_detail1,
d.project_detail2,
etc
from projects p
inner join details d on d.project_id = p.project_id
This will provide a flat table with the project title in the first column for all records.
Then, in the Report Attributes, you need to switch on Column Breaks:
In the Break Formatting section, set Breaks to "First Column"
In the When displaying a break column use this format, enter #project_title#
In the Identify how you would like your breaks to be displayed, select "Repeat headings on break"
Finally, clear the "Show" tick for the project_title column
There's probably something you could do to improve formatting etc, but this should give you a start.
Regards
Andy
