Master-detail: how to change master pk

ADF Business Components 10.1.3.42.70
JHeadstart 10.1.3.3.81
all,
i have a requirement to allow my users to change the primary key of a master record. the master record has multiple detail entities and about three levels deep. before i dive into it, i was wondering if there is any easy way to complete this using built-in adf capabilities?
thanks,
paul

Paul,
In a relational database like Oracle, primary keys are supposed to be immutable (unchangable). If you have a requirement to allow the user to change the primary key, then by definition, that "thing" is not the primary key.
If I had this requirement, what I would do is to use an Oracle sequence to generate a surrogate primary key for my master and put a unique key + not null constraint on the "thing" which is currently being used as the primary key.
Best,
John

Need Master-Detail relation to link Master column to 2 different detail col

I have a form with a master detail relation. The master block is a database table rec_shipments with a primary key of shipment_id and a bunch of other columns. The detail block is a table rec_containers with a container_id as the primary key plus column shipment_id, split_shipment_id, weight, volume, etc. The shipment_id and split_shipment_id are nullable.
When a shipment is received a shipment record is created and container records are created with the shipment_id populated and the split_shipment_id null. In the form a relation was created between the shipment block and the container block as shipment_id=shipment_id. This works fine. However, they have the ability to spit the original containers into smaller more manageable containers for distribution. For example if they receive a railroad car full of pallets of printer paper they may take and divide them, half into 1 rolloff bin and half into another rolloff bin. The rolloff bins will get a unique container_id for tracking. The record in the system created in the rec_containers table will have the split_shipment_id populated and the shipment_id null. In the screen they want to see the original containers (railroad car) and the split containers (rolloff bins) when the query the shipment.
What they want:
Shipment_id -- and additional information
Railroad Car ID plus additional information
Rolloff Bin 1 ID plus additional information
Rolloff Bin 2 ID plus additional information
My problem is the rolloff bins don't show up with the current relation because the shipment_id is null in the 2 rolloff bin records.
I've tried creating a view on the rec_containers table that is all the columns in the table plus 1 additional column that is
nvl(shipment_id,split_shipment_id) comp_ship_id
and set the relation to shipment_id=comp_shipment_id. I set the comp_shipment_id column to query yes and insert & update to no because I don't want to update that column in the view.
The problem is I can't update any columns, I get a can't reserve record for update or delete error.
Does anyone have any ideas how I can get the containers block to query all records where the shipment_id or split_shipment_id matches the shipment block shipment_id and still be able to update the records?
Thanks for any help.

Your idea of using a view is the best approach. In order to make the block updateable, you have to sst the property "Query only" for your derived item to "Yes". Witn this, the column will not be included in any further dml. About the locking... it may be that forms isn't anymore able to do proper locking when a block is based on a view. In that case, put an ON-LOCK-trigger on the block and lock the record by yourself doing y SELECT FOR UPDATE NOWAIT on the record. To just try if this would work you use a NULL in the ON-LOCK just to xheck if the dml-operations itself will work. if your view is based on only one table you have good chances that there is nothing to change, if you get an error like "View not updateable", you have to do some further adjustments
-Set the key-Mode for the block to "Non-updateable"
-Set the property "Primary key" to "Yes" for the pk-item in your block.
hope this helps

I have change my phone language to english. but the phone shows chinese language in the internet pages and with call details. how to change it. why is this occuring?

i have change my phone language to english. but the phone shows chinese language in the internet pages and with call details. how to change it. why is this occuring?

If the phone is not unlocked, let's say for example it is locked to another carrier such as at&t, when you put in the Tmobile SIM in, the phone would complain about the SIM.
Does your phone do that? If yes, then the party that sold you the iPhone4S (if you purchased it from another person) may have not done the unlocking properly, and that may explain why Tmobile is insisting on the phone being locked.
If you purchased your iPhone4S new from Apple, did you pick Tmobile, or did you choose unlocked?
If you picked the Tmobile choice, then it should come up ready to use.
If you picked the unlocked choice, then you would need to visit Tmobile to purchase a nano-SIM and usually they should be more than willing to help you, since you're paying for their service.
But as you have indicated, this phone is under AppleCare, so if it doesn't work with a supposedly good Tmobile SIM, the quickest way to fix this is to get a replacement phone. When we troubleshoot we always try the least time consuming methods first.
You may have noticed it, that a good number of unfortunate uses of the iPhone4S have had their wifi become strangely disabled after upgrade to iOS7. Your situation is the reverse, your wifi is useable but not your cellular network.
In the mean time, you can apply for a Google Voice account (see http://www.google.com/voice), and obtain a free North American telephone number. You can then download one of many free Google Talk applications. Set it up, and you will be able to call and receive phone calls using your wifi. This would be just for the transition period before you get a useable phone.
Google voice provides average voice quality calls to and from US & Canada numbers for free for 1 hour per call. You can use this as a temporary work around while you are waiting for your replacement phone.
Cheers!

Obiee 11g - Master/detail : How to initialize details ?

Hi gurus,
I'm using the last version of obiee.
I have a dashboard with master/detail. The master/details are working great when I click on cells.
But I have some "initialization" problems.
- master/detail with a prompt list on the master table
a change on the list won't initialize the detail. I would like to have the detail refreshed with the first row of the master.
- master/detail with different order by on master and detail
the initialization value of the detail does not fit with the first row of the master.
Is it possible to achieve this ?
Thanks in advance for your help.
Emmanuel

Hi Dpka,
Thanks for sharing your view . I ,even observe the same 'error' message returining false value at the bottom-left of my browser when set up the Master detail even and clicked my table column to reflect the value in the graph .
But my situation is bit tricky . I can't expose two different views to see if separating the interaction works well or not . In my case I have only 1 report with 4 compound layout(with pivot table(master) and Graph(detail)) having view selector . So this is practically not separable as this incurs loss of other functionalities.
Do you have any suggestion in mind . I tried to see Supportweb and doesn't have any valid bug reported :(

Master - Detail -- How to Hide page if no detail records

I'm hoping to be able to hide a page if no detail records exist for the master query.
My master query:
"Company" and "account" and balances for each account
(balances carry forward from previous months)
Detail Query:
transactions for each account for a month
-- Linked to the master by "account-id"
The master query is grouped into 2 parts:
a) Company
b) account and balance
Sometimes an account won't have any transactions during the month (especially if the report is run at the beginning of the month)
If I create a "summary" count field in the "account" group based on the transactions, then I can hide (not print) the "account" frame.
But I can't figure out how to do this for the "company" frame.
I'm probably missing something simple (or maybe not)
Any suggestions?
Thanks,
Eric

So basically you are showing each account on a separate page?
Move the objects shown in Company repeating frame to the account repeating frame. In this case company repeating frame will be blank. And your already created format trigger to hide account frame will work for both (company+account). So whenever any account is zero, it will hide all objects within the frame. Parent frame doesn’t contain any objects, it would not show the parent frame for that account. Make sure vertically elasticity of the frame is variable.
Hope this helps.

Master Detail module returns to Master page after Detail record saved

Using Oracle Designer Editor version 10.1.2.0.2 I have generated a Web PL/SQL package
set up as a Master/Detail where the Master and Detail records appear in separate windows.
The Master window contains multi-records each with a link to the related Detail records.
The user clicks on the Detail link and the window that appears will allow the user to insert
a new Detail record. Once the user clicks the Save button I need the Detail window to disappear
and the focus returned to the Master records preferably after a new query is performed.
What are the steps I need to perform to navigate back to the Master page and close the Detail
page?
Thanks,
Mark

The simple answer is that to do exactly what you want would take some fundamental changes to the way the framework works. The actionInsert procedure does what it does - it saves the changes and redisplays the form. You can do post-generation changes to make it do something else, like return to the Master, but I'd advise against it.
But if you want a way to return to the Master window, where the user clicks a button or link on the detail form after saving changes, that we can do. Just make a note of the URL that does the initial display of the Master page - probably my_module_name$.startup. Go into the detail module component, and click the User Text tab. Then at Text Location, "Bottom of View Form" (or Top if you want the link there) add for a link:
htf.anchor('my_module_name$.startup','Return to Master')Or for a button:
htf.formOpen('my_module_name$.startup','GET')||htf.formsubmit('Return to Master')||htf.formCloseYou may need to set the SECECS preference for this module to "No" to get this to work.
An alternative to my method is to define an Action Item in the module that does a navigation. I often am linking directly to the View form for a master table, rather than a record list, as you are, and Action Items don't work well for that, but one might work fine for you.

How to call SQL Insert on Master Detail Page when new master and detail rec

1. You can set the Jheadstart group property "Display New Row on Entry" to true
2. You can do this inside ADF BC: overwrite the create method on the master view object and after the call to super, look up the detail view object and create three rows there as well.

How to change Master Agreements search channel in Workbench

Hi All,
When we search in Master Agreements search channel in workbench then it displays a report just below that search, and when we click on that then it displays Master Agreement Search Agreement Detail.
In this details sub-agreement payment terms are not coming because Class id is different, but when I look into standard report : Master Agreement Search Agreement Detail, there query is having class id 1003.
Is it possible to replace this standard query in report or if we can replace this report in Master Agreements search channel in workbench.
Please advise.
Regards,
Prabhat Pandey

I see. I think SAP does not allow the standard FCI queries to be linked to Custom ones from the Setup --> Reports section.
In this case, you will first need to create a CUSTOM version of FCI-ConSearchMore and then link the custom version of FCI-ConSearchAgrDetail to this via the Setup--> Report section.
Then in the Setup--> Desktop Channel, you would need to go into the Master Agreement Search link and update the Parameter Definitions section with the new custom queries. This will ensure that in the Workbench page of the user, the desired results will be displayed.
Hope this helps,
Thanks,

Session-syncronized web portlets (a la master-detail), how to?

Hi.
Here is what I want: I have a number of servlet portlets on a page. The user activates a form action on one portlet. The parameters go to that portlet only. The portlet calls some data provider (e.g. a servlet) to fetch some data. When the data arrives the portlet makes it available to all portlet-threads (do i undersstand it correctly?) in the session and tell them to go and present the data according to their predefined XSLTs.
Now my questions are: Is there built-in support for this syncronization in Portal? What should be the preferred way to do this? Or have I missed something in the docs? (In that case my appologies, but please point out for me.)
FYI, our current solution is to have all portlets send requests with session info to a "conventional" servlet where the threads for slave portlets are put on hold and the master is passed on to the data layer. When the data comes back it is converted to XML. Then all threads in the session fetch the XML and send back to their respective portlets where the XSLT is done. Any comments on this solution?
BTW, what is the best way to syncronize servlet threads based on session?
Any information are much appreciated.
Jian Hu

One way of approaching your issue is to simplify. While portlets are executed in parallel, you are guaranteed that they will all be called at a point right after the page is requested and that they will all complete when the page is rendered (either by success or timeout).
You cannot predict the order of execution between those two points in time, but you can use those bounds to your advantage.
For example, if you can guarantee that you can commit information to a database before a new page request, you can have all your portlets read from that source.
Synchronization is a tricky issue and there are others that may know more about it. I'm just presenting one possibility.

Address Change in Customer/Vendor Master upon creation or change Master

Hi Expert,
We need to change some Address fields( *ADR6-SMTP_ADDR , ADRC-DEFLT_COMM, KNA1-TELTX, KNA1-TELX1*) in Customer Master based on some condition while creation/change the Master Data. I need to do same fields in Vendor Master as well.
I tried all the Possible exit Here.
If you know a Proper exit /BADI or one possible solution to solve my problem?
If anyone can provide any BAPI name which is used to Modify any customer/Vendor address will be very much helpful as well.
Thanks in Advance for your help.
Suman Adhikari

Hi Kesav,
For customer BAPI_"CUSTOMER_CHANGEFROMDATA" and "BAPI_CUSTOMER_CHANGEFROMDATA1" both Sales Organization is a required filed. Here we need to change some fileds(standard communication filed , Customer Email address, and Telex No) based on telex filed of customer for Customer irrespective of Sales Organization or any other constraints. The same requirement is for Vendor as well. If there is any proper exit/badi where KNA1 and address structure ADRC,ADR6 etc are available that will we good.
I just need to modify some address fields for customer as well as vendor. If there is any BAPI for change address(customer/Vendor) then that will also be helpful.

Questions on Master-Detail HTMLDB HOW-TO

Hi all
I have created a 3 page application based on the master detail how-to given at http://www.oracle.com/technology/products/database/htmldb/howtos/index.html
Instead of DEPT and EMP tables I have PERSON and PERSON_ADDR tables. The PK of PERSON is the person_id and the PK of PERSON_ADDR is the person_id and addr_start_dt. Person_id column in PERSON_ADDR is obviously the FK to the master table PERSON(person_id).
At first I had problems trying to create the pages themselves because the wizard always hides the person_id column on all the forms(and I don't want that,even though it is a sequence number I still want people to see it) , it being the PK, then somehow I managed it to display the person_id by replacing the EDIT link with the person_id itself. Now if a person already has an address and I click on EDIT then it copies the person_id values and others to the next page and all looks good but when I try to create a new address it does it ?? (It should take across the person_id as well)
My PERSON report is on page 1, when I click edit against a person it takes me to page 2 where I can see+change all the person details plus I can see the person_addr details. When I click edit against a person address it takes me to page 3 and I can edit all the address details nicely copied to the new page but when I click CREATE on the page 2, then all the fields appear as NULL on page 3( all the fields but the person_id should be null here). How can I fix this ?
Also, for my person address I would like to validate the address dates , there should be no overlapping start and end dates for a person's address. How to do this ? I think I will need to create a function to which I pass the person id and the new start and end dates and this function returns error message,if any, or null. I had a play around with validation and I think I need to use "function returning error text", what should I put in the "validate expression 1" box then...just something like
begin
my_function(param_1,param_2)
end;
If yes, then what variables would store the new start date and new end date of an address.
Lastly, for every table do I have to user a sequence number or a trigger to define a primary key, what if the primary key is just a character code and I want the users to add it ?
Thanks a lot in advance !!

thanks Marc.
Yes you are right, I used the 1.5 viewlet. I will try the master-detail wizard now.
With the primary key problems, for things to work nicely in HTMLDB, do you suggest each and every tables should have a sequence number generated primary key ? We have some tables for various statuses like ACTIVE,CLOSED where these codes themselves are the primary keys, so you suggest making these codes unique keys but still have a sequence number PK ? Also when I want the users to enter the primary key themselves I will let them enter new ones but not update existing ones, so data entegrity is maintained.
I was able to work out how to create validations using "functions returning error text" but my problem is I need to be able to compare what the user has just updated/entered with the data that already exists in the table. I have a table called person_Address having columns like person_id, start_dt,end_dt and various other fields. The primary key is person_id and start_dt and I need to put a validation which avoids any overlapping addresses. Overlap as in there can be only 1 active address for a given start and end date range. Does HTMLDB has something like :new.start_dt the way we can write database triggers ? Please suggest a way to do this.
Lastly, how does HTMLDB handles error messages raised by table triggers. Can they be shown along with the item on the page as we can with the other HTMLDB validations ? I have many tables with all sorts of triggers and if any validation fails I generally do...raise_application_error(-20001,get_my_message(234));
get_my_message function returns the message text for message number 234 . Will this message be displayed somewhere or not ? Do I have to duplicate my validations , once in the triggers and then in HTMLDB as well ?

ADF Faces Query Panel: How to display master data in detail table?

Before stating the question, here is the background:
I've a Fusion ADF (model/viewController) app that includes 2 tables with a master-detail relationship. The master table stores error numbers and associated levels of logging severity; the detail table stores the actual message text. These need to be separate, related tables because the requirement is that message text for a given error number can vary by product release.
Messages are added in a bounded task flow; data for the master table entered in 1 fragment, data for the detail table in a 2nd page fragment. In the app, the Entity Objects for these tables are related with a foreign key association and have a composition association. This was done because the error numbers are generated in an Oracle DB sequence, and from what i have read that is a way in a task flow to have ADF put the number generated for the master table into the related key of the child table.
The question is this:
I need to create an ADF query panel with a table that searches on the detail DB table. However, i also need to use a couple of fields from the master DB table in both the query and in the ADF table. In addition, I need to add the ability for the user to edit either the master or detail record for the row he/she selects in the ADF table. I know how to create a view that would display the info i need; however, i have not been able to figure out how to obtain the keys for the selected ADF table row and pass them to the task flows that would edit.
The master table has a numeric primary key. The detail table primary key consists of a foreign key to the master key and also a release number.
I'm new to ADF and have been struggling with how to do this: i've a workaround that is functional but too klunky to be a permanent solution. So, could someone point me to some information on how to accomplish this?
Versions: JDeveloper 11.1.1.4, ADF Business Components 11.1.1.59.23
Thanks for your help!

Thanks. I tried this out, but ran into an issue in that the detail table has 2 keys - a foreign key to the master primary key, and a 2nd key that uniquely distinguishes the detail. So i tried various things centered around using the SetCurrentRowWithKey operation and trying to obtain the selected ADF table row using an EL OF #{data.<pageDef>.<Iterator>.currentRowKeyString}; however i could not get the detail record for the selected row to display.
I did find another approach that worked - I am wondering, is there anything problematic with this approach?:
1. Create a VO joining the Master and Detail tables, with the Detail table being updatable.
2. Made sure the applicable attributes were defined as keys.
3. Add a query panel w/table using this VO.
4. Create an ADF form based on the VO, showing the updatable fields.
5. Create a bounded task flow with the following set on the Behavior tab:
a. Share data controls with calling task flow
b. Always Begin Transaction
I specifically am wondering whether "Share data controls with calling task flow" has any negative implications or gotchas to handle. The doc at http://download.oracle.com/docs/cd/E21764_01/web.1111/b31974/taskflows_parameters.htm#ADFFD1693 doesn't suggest so, but just wanted to double-check before I go down this path.

Master Detail Form - How 2 update a field in the Detail form using a query?

Hello,
I have a master detail form with, each master record having a fixed(6) number of detail records. One of the fields in the detail record is the PART_DESCRIPTION field. I am trying to update this field by querying Table_X. TABLE_X is in the format of (desciption id, description). Description id runs from 1 to 6.
When the form displays, the PART_DESCRIPTION field for the 6 detail records needs to be automatically populated with the six values of description stored in Table_X. How can this be done?
Tried using session storage objects, but made no headway.
Would greatly appreciate pointers on how to go about doing this.
Thanks.
Dev

If you are on a Portal Version lesser than 3.0.9.8.3, then please try the following to populate
the PART_DESCRIPTION field.
Steps:-
1> Edit the form and go to the Additional PL/SQl section and put the following code in the
"...after displaying the page area" :-
declare
type t_vc_arr is table of varchar2(4000) index by binary_integer;
l_arr_desc t_vc_arr;
l_form_name varchar2(200);
l_form_state varchar2(500);
begin
l_form_name := p_session.get_module().get_name();
l_form_state := p_session.get_value_as_varchar2(
p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_FORM_STATE'
if l_form_state = 'QUERY_AND_SAVE' then
select description
bulk collect into l_arr_desc
from <schema>.table_x;
htp.p('
<script>
var descArr = new Array();
var Fidx = 1;
var formObj = document.WWVM'||p_session.get_id()||';
var fieldName = "'||l_form_name||'.DETAIL_BLOCK.PART_DESCRIPTION.0";
for i in 1..l_arr_desc.count loop
htp.p('descArr['||to_char(i-1)||']="'||l_arr_desc(i)||'";');
end loop;
htp.p('
for (var i=0; i < formObj.length; i++){
if (formObj.elements.name == fieldName+Fidx){
formObj.elements[i].value = descArr[Fidx-1];
++Fidx;
htp.p('</script>');
end if;
end;

Button enable/disable in Master-Detail table

I am using JDeveloper 11.1.1.3.0 and I have a page fragment (.jsff) which includes a Master-Detail table and the Master table has 3 buttons that get enabled/disabled based on the specific string within a column say, if the column has value, 'DRAFT', the buttons should be enabled. In all other cases, the buttons should be disabled.
The above mentioned scenario works in cases where the table has more than one row in the table; but in two cases the buttons don't get enabled even though the column has 'DRAFT' as its value:
     1. when the table first loads with the data populated in the table; clicking on the first row doesn't trigger the buttons, clicking on any other row triggers the buttons
     2. when there is only one row in the table
To resolve this, I tried looking at the logs for any specific information regarding the buttons getting enabled or disabled. I couldn't find info on setting up a breakpoint for the commandbutton and the disabled property which would enable me to determine whether it is being triggered as soon as the table gets populated or not.
How can I get the buttons to work per my requirements? Also, can I set breakpoints for the button and/or evaluate disabled property's EL expression?
Thanks in advance.

Navaneeth:
The buttons are part of panelCollection which exists in panelHeader. As the below code demonstrates,
1. Buttons are defined in the toolbar (t2) in panelCollection (pc1)
2. Each buttons' partialTrigger is set to the table (md1)
3. Tables' (md1) partialTrigger is set to the toolbar (t2).

                    queryListener="#{bindings.ProductIdPanelSpecVersionToolNameQuery.processQuery}">
            <af:column headerText="#{bindings.PanelSpecTesterSpecView1.hints.ProductId.label}"
                       sortProperty="ProductId" sortable="true" id="c39"
                       filterable="true">
              <af:outputText value="#{row.ProductId}" id="ot28"/>
            </af:column>
            <af:column headerText="#{bindings.PanelSpecTesterSpecView1.hints.Status.label}"
                       sortProperty="Status" sortable="true" id="c43"
                       filterable="true">
              <af:outputText value="#{row.Status}" id="ot40"/>
            </af:column>
          </af:table>
     </af:panelCollection>
</af:panelHeader>The fact that the above code works when there are multiple rows tells me that buttons are having trouble reading the first row of the table.
Also, I changed the displayRow property for the table from "selected" to "first" but no luck either.
