Master/Detail Development Issues

Hi All,
Could you please share your expertise if you faced the problem listed below
1)I have a form based on a single table with two fields (org_id ,org_name) to maintain organization
a)org_id is getting value from sequence.when I open the form,I see the sequence getting populated,
looks good for insert mode,but for Query/Reset Mode ,it doesn't work,because the value(new sequence number) doesn't exists
WorkAround : Go to that field and nullify the value for the org_id and then do Query/Rest ..
Result : It works.
Is there way I can clear the Value for the field Org_Id(which is populated by sequence) after Reset Button is pressed.
If So ,please share your ideas
b)With the above form,,If I hide the Column Org_id (still sequence is generated to insert value)
the form works fine for Insert mode..but it errors out for Update/Query/Rest Mode ...
Any solution for this ?
The user doesn't want to see the Org_Id.
2) I have a column called Requested_By in the form..where I want to populate LastName,FirstName
How can I achieve it ?
3)How to set format mask for the field that represents dollar amount ?
For Eg :for $100,000.00 should i say --> $$$,$$$.nn ????
4)I have created a Master /Detail Form...I am displaying 5 lines on the detail block.If the user wants to enter more records how do I accomplish it .? In other words I am not seeing Next/Previous button on the detail block ...where as I see those buttons in the Master Block in Query Mode.. ...
5)I have a LOV (to list items)..When the user selects the item from the LOV in the ,is there a way ,I can store the Item_Id which is a hidden column for that row in the detail block
6)In which directory I can see the archive files to delete physically which I no longer needed?
Thanks in Advance

A couple of very quick answers for now...
1. You can write code in the PL/SQL section of the Save button to populate the Org_Id. Loop through the details and if the action = 'INSERT' then A_ORG_ID := the next sequence value.
2. More coding can do the trick. Where do you want to get the FIRST and LAST_NAME values from?
4. It doesn't exist, you cannot (by default) change the number of detail lines at run time.
You can code a button for it but in the meantime, this workaround works:
- User enters all details, clicks Save. The form will be cleared
- User enters same Master entries, but new Details entries and Saves again. It will append the new details to the Detail table.
6. Are you referring to the old code versions for your M/D form? If so, click Manage next to your M/D form. On the Develop tab, click Delete. It will bring up all the versions you can delete.

Wizard generated Master-Detail form issues

The wizard-generated master/detail forms have several severe usability issues when the "Choose Layout" option is set to "Builder master detail with: edit detail as tabular form on same page".
Some of these issues are:
- The form has two Apply Changes buttons, one to save the master row and one to save the detail row. Users find this very confusing. If you save the master row changes, any changes to the detail rows are lost and vice versa.
- The form has two Delete buttons, one to delete the master row and one to delete the checked detail rows. Users find this confusins also. Clicking the lower delete button discards any other changes that were made.
- The Add Row button also discards any other changes that were made.
The first two issues are easily fixed. With a few simple changes to the generated page, I can make it so there is a single "Apply Changes" button that 1) saves any changes to the master row, 2) saves any changes to detail rows and 3) deletes any checked detail rows.
I cannot figure out how to solve the third issue (that the add row button discards any changes). I can make it so the "Add Row" button saves the changes, but this isn't user friendly either; I don't think any changes should be comitted unless the user specifically presses 'Apply Changes'.
So far, I thought of several ways to possibly fix this but can't get any of them to work. Some of the ideas were:
1. The 'Add Row' button could run the automatic row processing and MRU processes, but not do a commit untill/unless Apply Changes is pressed. I don't think this is feasible because http is stateless and connection pooling may be used, so we can't have a transaction that spans http requests.
2. Move the Add Row process to page rendering so that the detail table always has an empty "add row" row thereby making the Add Row button unnecessary. I tried this, but it looks like the add row process was designed to run during the page processing, not during rendering, and it fails with a divide by 0 error when it is run during page rendering.
3. Use client-side DHTML (instead of the HTML DB add row process) to add an empty row to the html table (i.e. add row button does not do a submit, it is handled entirely on the client). I tried this, but the MRU process fails because it doesn't expect the added row.
If anyone has any other ideas on how to fix this problem, they would be greatly appreciated.
HTML DB solves this problem in the SQL workshop create table wizard.
In HTML DB 1.6, the "Add Column" button does a submit but somehow saves any changes that were entered.
In HTML DB 2.0 beta, client-side DHTML is used (my approach 3 above).
Can someone from Oracle share how the HTML DB create table wizard solves this problem?

Eric,
Thanks for your feedback. Iâll add your suggestions to our list of tabular form enhancement request.
The wizard generates a regular form for the master record and a tabular form for the detail records. As you pointed out, itâs quite easy to customize this to your individual needs.
Unlike regular forms, thereâs currently no session state concept for tabular forms, so you either need to write your data to the database, or you will loose any changes if you e.g. paginate. For the same reason, the âAdd Rowâ button and the associated process is generated so that any changes are saved to the database before adding a new row. Of course the MRU process that is executed on âAdd Rowâ can be removed, if that is the preferred behavior.
A work around would be to code the DML processes for tabular forms manually, and temporary store the data in HTML DB collections to simulate a stateful behavior.
In HTML DB 2.0 we started adding DHTML features, such as the create table wizard youâre referring to. Some features, like the pull down menus, will be available to be used in your own applications. Other features, like the DHTML tabular form, wonât be available for custom applications in 2.0.

Master detail form issue retrieving service price automatically

Hi,
I developed a master detail form in order to process service requests.
On details block I'm trying to retrieve automatically service price after I select service name from LOV.
For this purpose I created a application plsql process
declare
v_price service.price%type;
begin
select     price into v_price
from      service
where      service_no = 1;
htp.prn(v_price);
exception when others then htp.prn('An error occurred retrieving the PRICE');
end;
Which process I'm calling through javascript function in order to retrieve service price.
<script type="text/javascript">
function GetServicePrice(pThis)
var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
html_GetElement('f07_'+vRow).value = new htmldb_Get(null,html_GetElement('pFlowId').value,'APPLICATION_PROCESS=getPrice',0);
</script>
Instead of price it returns this value: "[object Object]".
Is it possible to work as I intended or it should other way around?
I appreciate your help/comments.

Edited by: Tonito99 on Mar 8, 2013 3:32 PMIf you are on apex 4.2 why are you still using the legacy/undocumented methods?
You should use new javascript API apex.server.process
apex.server.process ( "getPrice", {
success: function( pData ) { $s('f07_'+vRow, pData);}
} );

Master detail form issue

Hello,
I am unsure if this is a bug or how I'm doing things. I'm using version 4.1.
I am creating a master/detail report (on the same page) using the wizard to create the page. I have no problem creating the page and it works. The only changes I make to the detail region (which is a report) is to set it to display one record at a time, enable partial page refresh and change the layout to a vertical list including null columns. Essentially I want to see one record at a time. I can certainly page through them one at a time. However if I press "Add Row" it creates a new blank record below my existing one. If I keep pressing "Add row" I keep getting more blank rows. Shouldn't this blank row overwrite the currently displayed row so that there is only one row at any given time (whether its blank or a populated line). If I'm saying I only want one shouldn't it only ever display just one record regardless of whether your adding or reviewing existing detail records. It seems to me that if I tell it I only want one row, it shouldn't allow me to keep adding rows indefinitely which end up getting added to rows already on the screen. On a vertical listing with a lot of fields, you could end up scrolling for days.

Hi -
My assumptions are:
1) That you have created Master/Detail form with both Master and Detail regions on the same page.
2) The problem of NOT seeing the Detail happens when you are inserting (not updating) on Master,
in other words when you are creating a new user in Master section.
The Detail section (as created by Apex Master/Detail wizard) is a Report with a Condition set for display:
"Value of Item in Expression 1 Is Not Null" with Expression 1 populated with PK of Master.
So, change this condition to None and empty Detail section will appear in Create mode.
Note that you must now set the Form object that holds the PK for new Master record by some means,
(maybe a Page Process or such) before the Save is done, otherwise Detail record will not have FK.
Also you are going to have to play with the Conditions on the ApplyMRU and ApplyMRD Processes created
by the wizard to make sure they are only firing in Create mode when the Save for the whole page is submitted.
Lastly you can clear the values on the page with a Process of type "Clear Cache for all Items on Pages" that fires
last after page submission, again this may need a Condition to prevent clearing items before you are ready...

Master Detail relation Issue

hi all
I am facing an issue in Oracle Forms when I am trying to add a database item to a database block. As soon as I add the new database item to this block, an already existing relation (created between this block, as detail, and another block) stops working and ‘No Data Found’ exception occurs.
Please let me know if anyone has come across the similar issue or if I am missing something.
Thanks in advance

How did you created the database item?
copy - paste another item and re-named?
If that is the case, then check the column name property of the newly created item,
give the correct column name and try.
If that is a list item, if all the possible values are not present in the elements, this problem can occur
If that is a check box item, then if other values property is set as not allowed, then also this problem will come

Hi,
It looks like:
SELECT    m.id, m.value, m.charges
,       SUM (c.qty)      AS total_qty
FROM       master      m
JOIN       child           c     ON     m.id     = c.id
GROUP BY m.id, m.value, m.charges
ORDER BY m.id
;If that's not right, then post a little sample data (CREATE TABLE and INSERT statments) and the results you want from that data, formatted so it's possible to tell what is in each column. When posting formatted text on this site, type these 6 characters:
(small letters only, inside curly brackets) before and after each section of formatted text.
It's also helpful to post your query, even if it's not quite right.

Issue with Master Detail relation in OAF page -- Help

Hi,
I am developing an OA page with a master detail relation. The detail records are displayed in the subtab region.
The issue that I am facing is as follows:
If there are 2 detail records in the detail table, then my page is displaying these 2 records twice i.e.
Detail Records:
Header Id Line Id
2 1
3 1
Header Id Line Id
2 1
3 1
If the number of detail record increases, then again the display also increases that many times i.e. 3 records gets displayed thrice.
Kindly help to figure out the issue.
Thanks In Advance.

Hi,
Take the following actions.
1. Try to display your records in simple Table and remove it from subtab,
2. check relations as well, you can delete and re-create all the relations with EOs and VOs and recreate them.
3. Also check when your VO get popluated that how many rows are there in Detail VO ?
For example.
int x = yourViewObject.getRowCount();
System.out.println("Number of rows in detail view Object"+x);

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

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.

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.

Issue with Master Detail OAF Page

Hi Friends,
I have an issue with the Master-Detaiil Page.
I have developed a Master-detail form in OAF similar to the one in Oracle Forms. The master details are appearing fine. I have created a transient variable selectFlag that represents if the master record is selected. I am also able to see the detailed records after I have written the code in CO to populate the details table when a master is chosen.
But in the detail table I am seeing all the records. I should be able to see only the records that are children for the master record.
I have created the ViewLink as well. How can I pass the id of the master record to the detail table.
Any ideas. Kindly help.
Thanks

Hi,
Are u using partialAction on master form for this ?
You can add parameters from property inspector and put some unique attribute from VO and later filter the details record based on that.

Master-Detail Form in Form6i Developer

First of All Hi to all Respected Gurus.
I am stuck in a very basic element and that is Primary-Key/Foreign-Key relation. I am trying to create a Master-Detail Form based on following structure. Records in Master Table and Child Table are saving (inserting) but Primary Key of Master Table is not saving (inserting) as "Foreign Key" in Detail Table.
Here is Table Structure(s)
Master Table Name : MGTC_EDM
CREATE TABLE MGTC_EDM
EDM_ID NUMBER, -- PRIMARY KEY
BILLING_DATE DATE,
CONSTRAINT PK_MGTCEDM_EDMID PRIMARY KEY (EDM_ID)
CHILD TABLE : MGTC_EDD
CREATE TABLE MGTC_EDD
EDD_ID NUMBER; -- PRIMARY KEY
EDM_ID NUMBER; -- FOREIGN KEY RELATION WITH MGTC_EDM
MEM_ID NUMBER;
AMOUNT NUMBER;
CONSTRAINT PK_MGTCEDD_EDDID PRIMARY KEY (EDD_ID),
CONSTRAINT FK_MGTCEDD_EDMID FOREIGN KEY (EDM_ID)
REFERENCES MGTC_EDM (EDM_ID)
TRIGGER OF "BEFORE_INSERT" IS APPLIED ON BOTH TABLES TO AUTO-POPULATE INCREMENTAL ID
IN FORM6I, I'VE APPLIED A 'KEY_NEXT_ITEM' TRIGGER ON BILLING_DATE FIELD OF MASTER TABLE TO COMMIT THE RECORD AND TO MOVE THE CURSOR TOWARDS DETAIL BLOCK
AND THERE ARE NO MORE TRIGGERS IN THE FORM.
AS CURSOR MOVES TOWARDS DETAIL BLOCK, RECORD IN MASTER TABLE SAVES (COMMITTED) ON AUTO AND WHEN I PRESS "SAVE" BUTTON TO SAVE THE RECORD IN CHILD FORM DETAIL TABLE ALSO COMMITTED
BUT WHEN I PRESS F8 TO EXECUTE THE QUERY ONLY MASTER RECORD SHOWS AND NO RECORD SHOWS IN THE DETAIL TABLE. WHEN I CHECKED IN DETAIL TABLE IN TOAD, IT FOUND THAT PRIMARY KEY OF MASTER TABLE (EDM_ID) NOT SAVED IN DETAIL TABLE.
PLEASE HELP.

Dear Mr. O.Developer, Many thanks for your reply.
Yes, I've created relationship. Relationship exist in Master_Block and below is the detail
Relationship Name = MGTC_EDM_MGT_EDD
Relation Type = Join
Detail Data Block = MGTC_EDD
Join Condition = MGTC_EDD.EDM_ID = MGTC_EDM.EDM_ID
Delete Record Behavior = Non Isolated
Prevent Masterless Operations = No
Deferred = No
Automatic Query = No

Salesforce issue- Accessing Objects and Reports with 2 master-details

I'm using Crystal Reports XI r2 with the Salesforce data connector installed, and I know the same issue exists in CR 2008 as well. With version of the Salesforce API that the Crystal - Salesforce connector is using, objects that have 2 master-detail relationships are not available to add to reports. Even if I create a stanard Salesforce report with an object with 2 master-details, that report isn't available in the "Stored Procedures" of Salesforce in Crystal. The API is about 3 years out of date, any word on when a new version will be available? This is a big limitation.

Try SP3 for CR 2008. Please re-post if this is still an issue or purchase a case and have a dedicated support engineer work with you directly:

Issues in Processing the Master-Detail Form values

We have a requirement in Oracle Internet Expenses (11.5.10) to fetch the form values from the Expense Allocations Screen.
This page is based on Multiple VOs with Master Detail relationship. The data from the VOs mentioned are displayed in the Hgrid region.
I need to fetch the input values for three fields (from different VOs) and pass them as paramater to the database function to perform the validation.
Here, I am creating the handle for VO objects and using the Row object getting all rows in range (getAllRowsinRange()).
The issue here is always, the Row length() is always fetched as 1 even it has multiple rows.
Any help on this would be highly appreciated.

Using Select Options u will get mulitiple values also u will get values like table.

Master/detail issue

I have a tricky if convoluted implementation issue and hope you can assist with resolution.
I have a form with a master/detail relationship.
The master block has a primary key called master_id and the detail block has three foreign keys (caller_id, requested_id and responder_id) that the primary key master_id must map to.
master table (master block)
master_id varchar2(4);
detail table (detail block)
caller_id varchar2(4)
constraint fk_callnum foreign key (caller_id) references master(master_id),
requested_id varchar2(4)
constraint fk_reqnum foreign key (requested_id) references master(master_id),
caller_id varchar2(4)
constraint fk_resnum foreign key (responder_id) references master(master_id)
I know it is poorly designed. They do not want to redesign.
This is the process flow.
A physician calls our office to speak with another physician in our office, an operator searches the master block with the caller's(physician's) name and area he/she is calling from. If information about that caller exists on the master block, it is displayed on the master block.
The operator then takes the master_id of the caller and enters in it on the caller_id box of the detail block.
The operator then goes back to the master block and does a search of the name of the person the caller wants to speak to. If information about the requested physician exists, his/her id is entered on the requested_id box in the detail block. If contact is made with that physician, or with someone from his/her office, then the requested_id also becomes the responder_id. If the physician being asked for is not available and no one in his/her office is available to take the call, then the call is redirected to another office. In this case, the responder_id is different from the requested_id. Again, information about the office the call was redirected to will have to be searched for in the master block.
Now if I have not already confused you, here is where problem comes in for us.
The client has complained that they are duplicating their efforts. They want the information displayed on the master block whether it matches caller_id, or requested_id or responder_id of the detail block to be automatically be populated on the detail block. They only want to type the info on the master block and have their result be displayed on both blocks.
They have therefore asked us to do two things:
1, once you do a search for a caller, if there is information available about that caller, display that information not only on the master block but also populate the caller_id row in the detail block with information relevant ONLY to the caller_id automatically.
If you do a search about requested_id, display that information on both the master block and detail block; same with responder_id.
How can this be implemented. If possible, sample syntax.
I grappled with this syntax:
select col1..coln
into :detail.col1..:detail.coln
from master, detail
where ( master.master_id = detail.caller_id -- the physician that called
or master.master_id = detail.requested_id -- the person being asked for
or master.master_id = detail.responder_id) -- the person who responded to the call
and master.master_id = :master.master_id;
As you can see, this can only display records in the detail block only. I need records
displayed on both blocks. Any help/suggestions will be greatly appreciated.
I can clarify further if need be.

Ok, I'm not sure if this syntax will work but it might give you an idea to build on. I'm assuming that each of the ids are stored in different base tables.
Get rid of the master detail relationship.
Give the master_id field a LOV to enable searching.
The basic functionality to populate the detail section would be:
IF caller_id IS NULL AND request_id IS NULL AND respond_id IS NULL THEN
:detail.caller_id := :master.master_id;
execute_query;
IF caller_id IS NOT NULL AND request_id IS NULL AND respond_id IS NULL THEN
:detail.request_id := :master.master_id;
execute_query;
IF caller_id IS NOT NULL AND request_id IS NOT NULL AND respond_id IS NULL THEN
:detail.respond_id := :master.master_id;
execute_query;
END IF;
You may have to put each of the 3 detail fields in their own data block to get this to work. Something to work from anyway.

URGENT HELP PLS : Issue with Multi Level Master Detail block

This is an issue someone else had posted in this forum few years back but there was no solution mentioned, I have run into this same issue , The problem is as explained below.
Any help on this is appreciated.
Scenario:
There are 3 Blocks in the form : A (Master Block)
: B (Detail of A )
: C (Detail of B )
There is master detail relation created between A and B and B and C. So initially when we query for a record in Master A, it shows all records properly in B and C.
Now if i navigate to the first record of B , and then second record of B , records corresponding to that record shows up properly in C block.
Till now everything works fine.
Issue 1:
But in case after querying initially on Master Block A,If I go directly to the second record of B block, it clears the whole B block and C block.
Issue 2:
Same thing happens if I am on C block ( corresponding to second record of B block) and then navigate to first record in B block , it again clears the whole B block and C block.
Please Help !!
Thanks !

Thanks Xem for Your reply , I tried those settings but it did not help..here is the original link that to the thread that talks about the same problem ,
Issue with Multi Level Master Detail block
The last update to this was the following :
"I figured out that this is happening because Block Status is set to 'Changed' and this is causing it to clear out the blocks.
But cant figure out why the status is setting to 'Changed' "
Any Help from the form Gurus on this form in this matter is truely appreicated !!
Thanks,
Zid.
