Synchronizing Iterators for master view with multiple detail - how to ?

New to JDeveloper (from Forms) and after an introduction a week or so back, one question I have not yet answered with the ADF framework is how to synchronize iterators. Maybe I missed something simple, but if I have master table A with FK relations from detail tables B and C expressed as view objects and view links in the Model tier, when I package these up into the Application Module / Data Controls it seems I have 2 iterators for table A - one for it and it's detail set B, and another for it and it's detail set C.
So then, if I drag & drop one of the A data controls onto a page (say from the A-B link) as a read-only-table, my PPR actions from this table work on components derived from this same data control hierarchy - ie: on detail B. But to effect a change in the other detail relationship A-C, and components based on C, seems to mean moving this second iterator on A programmatically.
How is this generally achieved using the ADF ? I've seen content about chaining master-detail-detail, but this is really master-detail(xN). View links only ever specify 2 tables. It seems I need to put some code in somewhere to move associated iterators when another iterator is moved.
Also, is there an equivalent java code-point for the when-new-record-instance - ie: when an iterator moves to a different record, whether that be new or not. Not being able to find it thus far, I've put code in the executeQuery of the detail VO which fires when I need it, but there must be a better place.
Thanks for the help.

You can manipulate your AM Data Model so both details will be under the same master (as long as there are viewLinks from the master to both).
Then you can drag them to the page and add PPR as described here:

Master with multiple details

(JHeadstart release 10.1.2.) I can make a master with multiple detail pages work (displayed on the same page or different pages), except under one condition. Assume the following situation:
Master: View object A based on entity A
Detail 1: View object B based on entity B with a modified WHERE clause
Detail 2: View object C based on entity B (yes, same entity object as view object B) with a WHERE clause different than the one for view object B
A one-to-many view link exists between view object A and view object B, and another exists between view object A and view object C. The query for each of the view objects is standard (i.e., no expert-mode queries). The master and the two detail view objects (via their respective view links) are assigned to an application module.
I created a JHeadstart application structure file for the application module with Struts and UIX. I added view object A as the top group (table-form layout). I next added view object B as a detail group (form layout, same page) beneath view object A. I finally added view object C as a detail group (form layout, same page) beneath view object A (i.e., parallel to view object B). The module generated and built cleanly.
I ran the application, entered a master record, and saved the data. When I pressed the button to create a new record for detail 1 (view object B), fields appeared for the pages for detail 1 and detail 2 (view object C), not just detail 1. Also, the value of the Descriptor Attribute from the master record that linked it to the two detail pages populated the corresponding field in both of the displayed pages for the detail records.
This behavior does not occur if view object C (detail 2) is based on an entity different than view object B. Will JHeadstart allow a master to have multiple details where the details are based on the same entity object? Thanks.

Ray,
Unfortunately I cannot reproduce the problem. I filled in the A, B and C using a scott/tiger schema as follows:
A: Departments
B: All employees having a salary < 1000
C: All employees having a salary >= 1000
Then I created an application module with one group having two subgroups everything same page, just like you specified. Everything seemed to work fine. Do you have any idea what's different in your situation.

Examples of Master with multiple details

Hi Leo,
I want to create Master with multiple details
I have been trying for the similar example (Master with multiple details) for long time.
It seems in the following link, you have mentioned that you have done such examples.
Examples/Demos of APEX applications with Master with Multiple Details.
Can you please share the solution to my emaid address [email protected]
Or can anybody help me to get such solution with examples step by step.
I would highly appreciate for any help.
Thanks.

Ok, so here's the rundown.
Create a page with one "master" html region. In that region create your standard text/date/etc. items. Make sure that one of these is a hidden key field that is the key linking the master and details portions. Use a calculation to pre-populate the field from a sequence (or whatever uniqueness generator you choose). It is important to generate this key up front for the processing.
Next I created one report region for each detail table I wanted to link in. Make sure to count the total number of fields you want to work with and that the total is LESS than 50. This is critical. The report should be selecting the columns from APEX_COLLECTIONS for display and manipulation on the screen. It is best to explicitly associate these to the Javascript column numbers now. I used a process to pre-populate my detail entry areas with default values for ease. I also included a button to add a row to each area, but you have to be careful here to use a good combination of form attributes so that the page refreshes don't SUBMIT yet.
Once you have a report region generated from APEX_COLLECTIONS, you have to create the update processes that pull the information from the user modifications into the collection. This is the trickiest part of the whole thing. You have to use the APEX_COLLECTION.UPDATE_ITEM method, and you have to refer to the JavaScript column numbers for the source value and the collection column number for the destination. It is really easy to get these confused - I advise putting this all into a document or on a whiteboard for reference.
Once you have the update processes written (I prefer writing one update process per detail section), write your processes to write the data to the database. Again, I suggest one process for each detail table. Trigger them to fire on submit.
I also suggest creating a debug page to display all of the various collections and to help keep things straight. Once you have one detail area working, it is easier to get the others working.
If you need actual code snippets, let me know and I'll see what I can do.

Master with multiple details page, is there an example out there?

Many hints and suggestions can be found on this forum about building a page with a master with multiple details page. But is there a working example somewhere? It looks quite complicated to me.
Also I would like to know if it is because of my Oracle Forms background that I miss the possibility of building this kind of forms in application express. Are there other ways to setup the pages so that you can do without them?
thanks Rene

Let me elaborate on my requirements a bit:
The form I want to create should look like this:
Master
Atrtibute_1
Attribute_2
Attribute_3
Attribute_4
Details_1 Add Delete
[] item1 (read-only)
[] item2 (read only)
Details_2 Add Delete
[] item1 (read-only)
[] item2 (read only)
So basically it should be possible to maintain several lists of items that belong to the master record. Checkboxes allow the user to select records for deletion. The Add button shows a pop-up window that lets the user select an item to add.

Examples/Demos of APEX applications with Master with Multiple Details.

Trying to get my head round the way to best method/approach to present / allow a user to select / maintain a Master table and then maintain multiple Detail tables that are for the current Master. Typically in my Forms days I would have used tab canvases as placeholders for maintaining the related individual detail table rows. But in the APEX world tabs are used as top level page navigational items. Are there any demos, tutorials or articles on how to implement Master with multiple Details using simple APEX pages with minimal bespoke HTML and Javascript intervention.

OLAP on 11g and Materialised Views with Multiple Value-Based Hierarchies

Hello OLAPians
I am trying to setup Orable BIEE to report on an OLAP cube with pre-aggregated data. As OBIEE is not able to hook into the OLAP directly i have to create an SQL cubeview.
Currently i am on a 10g OLAP environment and am using the oracle sample SQL cubeview generator to create an SQLview of my cube.
The cube itself has multiple dimensions and these dimensions have multiple VALUE-based (ragged) hierarchies and dimension members can be shared across hierarchies also.
Initially i had a problem running the view generator plugin because there is a bug within it that does not finish if there are multiple value-based hierarchies present. I was able to get around this by manually editing the limitmap for the cubeview and manually creating the SQL view.
The question that i want to ask is how robust is the 11g materialised views with multiple value-based hierarchies and the sharing of dimension members across different hierarchies?
Has anyone successfully been able to create a cubeview and import it into OBIEE without the hassle of manually editing the limitmap?
A problem arises with the value-based setup whereby if the client creates a newer depth in the ragged hierarchy, i need to manually create the limitmap and the cube-view over again, and then re-map the BI Administration mappings.

The simple answer to your question,
how robust is the 11g materialised views with multiple value-based hierarchies...?is that materialized views are not supported on top of value-based hierarchies in 11g. The reason is that it is not possible to write a reasonable SQL statement that aggregates a fact over a value-based hierarchy. Such a SQL statement is necessary if we want to create a rewritable MV on top of the cube.
But I suspect this is not what you are really asking. If you are trying to set up OBIEE on top of the cube in 10g using the view generator, then you will probably want to use the "ET VIEWS" that are generated automatically in 11g. These are generated whether or not you enable materialized views on top of your cube. I am not aware of any issues with the generated value-based hierarchy view support in 11g. Members may be shared between value hierarchies and you will not need to generate or modify limit maps.

Report for CS15 tcode with multiple material nos. in selection screen.

I want to develop a report for cs15 but with multiple materials.
Like in cs15 we enter the material and its plant, then click on multi level check box and get the output. But cs15 works only for a single material. I want to develop a report in which i'll give multiple material nos. and then i should get the output for each material entered just as the output that would appear in cs15 for that material.
How do i do it.
I have tried but i'm not able to track back.

Hi Priti,
try develop a interactive report which lists all the materials in the first screen and when you double click on each of the material then call transaction CS15 output by skipping the first screen .Use set parameter to pass the material .

Report with multiple Detail Area

Hi All,
Please see the Report pointed to the link below:
[Report with multiple Detail Area|http://us.share.geocities.com/felix5ac/fairway.jpg]
Some Explanations:
========================
(1) The line with "ABCDEFGH..." is variable data coming from the database in the Detail Area
(2) The lines with "WBLNX'" "123, 123.12",
"WBLNX'"
are variable data associated with the same Heading: "ABCDEFGH..."
(2b) There can be multiple lines of data in the detail area (i.e. 1 or more "ABCDEFGH..." and the associated WBLNX and numbers...)
(3) Item Code Descriptions ==> is a Header Info
(4) ARL ... and FPHI... ==> are variable data and lines in these area can be 1 line; it can be 4 lines; it can be 10 lines...
(5) Lines FROM "Artwork Procedures..." to the the end of the page are static.
QUESTION:
===================
How do I best design these Report with the multiple detail areas? Again, please see link of the Report above...
Thanks and Best regards,
Felix

Hi Felix
You can place the less detailed fields in the regular sections of the report and wherever you require multiple lines you can use the subreports.
Hope this helps.

"Refresh after" insert fails for DB-View with INSTEAD OF Triggers

Hi,
I have a database view with INSTEAD OF triggers defined for INSERT, UPDATE, DELETE.
For some EO attributes the refresh after insert and update is defined.
Posting to database fails.
According to Database 9.2 Manual and a previous thread (BC4J and Updatable Views the RETURNING clause is not allowed for database views with INSTEAD OF triggers.
Is there a workaround so the refresh after is done, but without the RETURNING feature?
I only need to refresh some values. The PK i can set in the create method of the EO so refresh via a additional SELECT would be possible.
If not Feature Request:
Add the possibility to do the "refresh after ..." with a 2nd SELECT using the PK instead of using the RETURNING clause.
Of course then it is not possible to set the PK in the database trigger. PK has to be set in the create method of the EO.
Thanks,
Markus

Hi Markus,
Turning on the stack trace (-Djbo.debugout put=Console - in the Project/runner) did help and I should have done it sooner. Turns out that when I constructed my EO based upon a database view - I should have left out the PKs of the base tables.
In my case, I am using an "Instead Of Trigger" to populate a multi-table arrangement (parent - child - grandChild - greatGrandChild relationship) where all base tables are using dbSequence/dbTriggers.
Final analysis - I would like to see BC4J handle this situation. I do not want to use View-Links and I should * not * have to resort to stored procedures and BC4J/doDML. If I construct a DB View this is participating in an parent - child - grandChild - greatGrandChild relationship that are using dbSequence/dbTriggers, then BC4J should be smart enough to construct VO knowing that I want to do insert, update, delete, selects - based upon this structure.
Thanks Markus,

Error handling for master data with direct update

Hi guys,
For master data with flexible update, error handling can be defined in InfoPackege, and if the load is performed via PSA there are several options - clear so far. But what about direct update...
But my specific question is: If an erroneous record (e.g invalid characters) occur in a master data load using direct update, this will set the request to red. But what does this mean in terms of what happens to the other records of the request (which are correct) are they written to the master data tables, so that they can be present once the masterdata is activated, or are nothing written to masterdata tables if a single record is erroneous???
Many thanks,
/ Christian

Hi Christian -
Difference between flexible upload & Direct upload is that direct upload does not have Update Rules, direct upload will have PSA as usual & you can do testing in PSA.
second part when you load master data - if error occurs all the records for that request no will be status error so activation will not have any impact on it i.e. no new records from failed load will be available.
hope it helps
regards
Vikash

Hi, I recently got an iPad air. Singed in for new registration with cc details as I had no other option
I already own an iPhone and also my husband owns one. Both have same Apple ID to sync with iCloud
But after registering for iPad all my free apps are asking me to purchase those free apps. I have no idea what went
Wrong, please help.

You created the same Apple ID with the setup assistant on the new iPad Air - the same Apple ID used for the iTunes and App Store on your iPhone?
There is no charge for a free app regardless.

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!
