Sample code to edit master detail records

Hi,
Could anybody please sned me the sample code to edit master and detail records.
Thanks,
Kavitha

Arjuna,
Thanks for your reply. Unfortunately the 'switcher' code which makes an attribute editable, works on a 'Read-Only table' page but not on 'Master-Detail table' page. The switcher code is:
<switcher childName="${uix.current.RowID.inputValue == bindings.RowID.inputValue ? 'selected' : 'notselected'}">
<case name="selected">
<textInput model="${bindings.RequestedBudget}" columns="14" readOnly="false"/>
</case>
<case name="notselected">
<textInput model="${uix.current.RequestedBudget}" columns="10" readOnly="true"/>
</case>
</switcher>
We do have individual bindings for all table attributes. Any suggestions will be much appreciated.
Thanks, Ali.

Foreign key validation while creating master/detail record in document mode

I am creating master/detail records in the document mode. And I am generating the master primary key in the create() method of the master Entity Object. Now I valdate the foreign key in the detail Entity Object's validateEntity() method by doing a query to the master table through some View Object.
But since the master record has not yet been posted (since it hasn't been committed) to the database, this query does not return any record and the validation fails in detail object.
And thus the create fails.
Please let me know if this is the right approach for doing this. If so where I am going wrong? Else please let me know if there are any better approach to do this.

Kunal:
Use a code snippet like the following:
--- Assuming you're in the detail EO's create method ---
oracle.jbo.server.EntityDefImpl eDef = oracle.jbo.server.EntityDefImpl.findDefObject(<package-qualified-name-of-the-master-Entity-Object>);
oracle.jbo.Row masterRow = eDef.findByPrimaryKey(this.getDBTransaction(), <foreign-key>);
If the row does not exist, masterRow will be null.
findByPrimaryKey first checks the entity cache (which will include your new master row(s)) and then go out to database (if it's not in cache).
Thanks.

Using EJB creating Master/Detail Record

Hi All
I would really in need of your help regarding how to show the information of master detail records in a single form
eg: one text field with department Id and a Search button which should give relevent employees details working in that particular department.
I tried with ADF business components it works fine..
I need to do through pure Session Beans and Entity Beans(note : not thru using EJB:UseBean Tag)
Please i will really appreciate your valuable help..
Thanks All
Have a Nice day

Master-details records

Hi Everybody,
i have a requirement to show master detail records.to show data i have 3 tables
they are 1) Flat_Master(flat_id,flat_desc,pic)
2)Flat_Detail(flat_id,flat_face_id,flat_loc)
3)face_tab(face_id,face_desc)
in my jsf page i displayed flat_master as master records and flat_detail as detail records
here flat_detail is updatable.so for flat_face_id i created a lov choice list based on face_tab table(ADF BC level).
so when master record i changed, my choice list is not getting changed amd even when page load also for the first record also it is not selecting..
How can i set this choice list value programatically based on master records?
Any ideas can you please share with me?
thanks

What is the proper way to record line numbers in Master/Detail records?

Guys and Gals,
Been thinking about this for awhile, but thought it best to ask the people who really know what they are doing.
What is the proper way to record & show line numbers in a Master / Detail record set?
For example, take Master/Detail relationship Orders and OrderItems. Orders has a column Document_Number and OrderItems has Document_Number, Line_Number. Line_Number should contain the row number 1,2,3,4 ... etc. for each row in a document.
Should I ...
<ol><li>Add a sequence and a trigger in the database? The FusionOrderDemo does this, but then the sequence never "resets" and I've got row numbers that keep incrementing. So one document has rows 4,5,6 and the next document has 7,8,9 when they should both have 1,2,3.</li>
<li>Programmatically take care of the row numbers? This seems like I'm asking for trouble. Anytime an insert or delete operation gets done, I'll have to iterate through rows and re-assign row numbers.</li>
<li>Is there a way to assign row numbers in a table iterator (or data collection?) to an entity?</li></ol>
Any suggestions would be appreciated. It's looking like #2 is my only option, but if anyone knows different I'd love the input.
Will

Thank you both guys.
As John said, I believe I'm looking for a gap-free sequence per master record.
The line number of the OrderItems table is the second half of the primary key. The first half of the primary key (DocumentNumber) is the foreign key to the Orders table.
Think of it like line items on an order or invoice. For example, if you were talking to someone on the phone concerning an invoice, you might say, "The pricing for line item #3 is incorrect." In this case, it's good to have a common reference. Or imagine a Microsoft Excel spreadsheet with no row numbers displayed! You'd never get anywhere if you had to explain something over the phone.
If this is tricky to perform, I take it using a sequence and trigger such as the Fusion Order Demo is the best way to approach the challenge for simplicity's sake?

Master-Details Record

I have a Master and two details records. I need to generate report for the Master-Details record.
I need to include some details from the Master table and some details from each of the detail tables.
For example :
In Master table: Employee_Number
Employee_Name
Company_Code
Company_Name
In Application Detail table: Application_Code
Application_Name
In Non-Application Details table: Non-Application_Code
Non-Application_Name
I need to include Employee_Name, Company_Name, Application_Name and Non-Application_Name in my report. How should I go about creating the report?and may I know what type of report style should I use?Should I use Tabular or Group Above?
Thank for your help

hello,
you might want to start off with a regular master detail layout and then modify the layout manually to fit your needs.
when running throught he wizard, you just select whichever fields you want to display.

Hi everyone,
I need your help, one more time.
I want to generate a file in ODI that have two distincts records of the detail, a master-detail records. The first one record contain general data and second one contains a second level information about the previous.
I got the result using a bad solution, loading the file line by line, but the file is so large and performace was very slow.
The expected result is:
001Purchase Order id 99
002Item 1
002Item 2
001Purchase Order id 150
002Item 1
002Item 3

BC4J - Inserting Master/Detail records in same transaction.

I know this is possible, but I seem to be missing something to allow it to happen within BC4J.
I'm creating a RowSet off of a View Object and inserting new Rows into this RowSet. This RowSet represents my child/detail records for insert into a child table.
I then create a new Row off of another View Object. This row represents my Master/parent record for insert into a parent table.
All of the above is being done in the same applicationModule transaction with locking mode set to Optimistic.
Before I commit the transaction, I grab the next sequence # to use as the primary key for the master record and the foreign key for the child records. I apply those to the newly created child rows and the newly created master row.
However, when I commit I continue to get a JBO-26041: Failed to post data to database during "Insert": error due to ORA-02291: integrity constraint (CUST_LICENSES_FK4) violated - parent key not found
If everything was created in the same transaction, why won't this allow me to insert into both tables with the correct primary/foreign keys? It's almost as if the child records are being inserted first prior to the parent record.
Any ideas?
Thanks in advance..

However, when I commit I continue to get a JBO-26041: Failed to post data to database during "Insert": error due to ORA-02291: integrity constraint (CUST_LICENSES_FK4) violated - parent key not found
If everything was created in the same transaction, why won't this allow me to insert into both tables with the correct primary/foreign keys? It's almost as if the child records are being inserted first prior to the parent record.This is due to the order of rows being posted. In this case it seems the detail row is getting posted before the master.
To avoid such situations, either you may implement your own post ordering by making sure that when a detail is to
be inserted, it's master is inserted or you may use "Composition Association" flag in the association wizard between
the master and the detail entities to let the framework manage a tight composition relationship between the two entity
types. BTW, there was another definitive thread recently on inserting master-detail in the
same transaction, but the forum search engine is so useless I can't find it. Anyone
have the msgid handy or know how to find that thread again??
FYI: the help describes the Composition flag functionality in terms of the Master record already existing in the DB. In our problem here, the Master is being inserted in the same transaction. Thus needs to be posted FIRST.
I got a integrity constraint exception too, then set the composition flag and now I get:

Editing "Master Detail" Details during Create Application

I have been using the wizard to create an application.
I have added a Master Detail page, I wanted to change the page name of "Master Detail" to something more meaningful.
I clicked on the Page Name and in the pop-up window I edited the page name.
On clicking 'Apply Changes' I get the following error: "Error in mru internal routine: ORA-20001: no data found in tabular form"
This appears to only happen for Master Detail pages as I can make changes to other pages.
Regards,
Jon

Hi Jon,
Thanks for reporting this issue. I've been able to reproduce this behaviour on apex.oracle.com. Bug *10202722* has been logged to track this issue. We'll endeavour to resolve this issue in our next release. In the meantime, as you know, you'll be able to modify the 'Master Detail' page name post-generation. Sorry for any inconvenience, but thanks again for reporting this.

Hilary

ADF BC : Problem in Inserting a Master - Detail Record

Hi,
I am new to ADF Business Components. I am into a project where i use only the ADF BC as ORM/DB Operations and for the front end I use some other framework. The Problem is.
I have two entity objects and a ViewLink between them. [Relation between "Order" to "Item" is (1 to many relation)].
[I saw many examples in forums where its explained with View Objects But here I DID NOT create any View Object. I have only Entity Objects]
(1) OrderEO [Entity Object for Order Table]
(2) ItemEO [Entity Object for Items Table]
(3) OrderItemsViewLink [A Viewlink where OrderEO.OrderId = ItemEO.OrderId]
All The Primary keys (for the "Order" and "Items" table ) are handled by Trigger+Sequence at the time of insert in DB side.
I created custom method to insert "Order" individually it worked fine.
I created custom method to insert the "Item" individually it worked fine.
But...
When I created and "Order" with some "Items" It failing to insert and throws an
Error : oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity: detail entity ItemEO, row key oracle.jbo.Key[0 ].
My Custom Method in the AppModuleImpl is like below :
public void createNewOrderWithNewItems() {
String entityName = "com.proj.entities.OrderEO";
EntityDefImpl orderDef = EntityDefImpl.findDefObject(entityName);
OrderEOImpl newOrder = (OrderEOImpl)orderDef .createInstance2(getDBTransaction(),null);
try {
// 3. Set attribute values
newOrder .setOrderStatusCode("CREATED");
RowIterator items = newOrder .getItemEO();
Row newItemRow = items .createAndInitRow(null);
items .insertRow(newItemRow );
newItemRow .setAttribute("itemDate", new Date());
newItemRow .setAttribute("itemQty", new Number(10));
// 4. Commit the transaction
getDBTransaction().commit();
} catch (SQLException e) {
e.printStackTrace();
} catch (JboException ex) {
getDBTransaction().rollback();
throw ex;
Here the "Order" is also new and related Items is also new. What I expect is to save the Order with Items in one transaction. How to achieve this. Please suggest.
Thanks
Narayan

PLSQL logic to insert master detail records

Hi All
I have a requirement where I need to do the following.
1: Have a headers and details table for some data that I need to insert
2: Transactions need atomicity...ie If the header record fails then the details should still be inserted , but with an Error flag
3: Needs good error handling
I'm trying to come up with some logic like so
1: Have a header cursor and a details cursor
2: Have the lines for loop inside the headers for loop and then do the inserts
3: If an exception is thrown for one record it should not error out the other records(this can be done with a begin end block)
Does anyone have a better idea for this...Is it an efficient way of developing header- detail inserts?
If someone has an example that I can go over I would appreciate that or a basic algorithm would do too..
Thanks

3: Needs good error handlingGood error handling is specific to the expected error and is defined by the specific business requirements.

If someone has an example that I can go over I would appreciate that or a basic algorithm would do too..If you provide an example of the error you expect and what you are supposed to do in that situation then it is possible someone could provide an example algorithm.

A sample code to check records of a system table?

hi ABAP4 experts,
We are pretty new at ABAP4. We would be appreciated if you can provide a sample code to check how many records and calculate a total amount for a specific field, e.g., DMBTR in a system table, e.g., BSEG. Note: there is no any selection for this table BSEG, we just want to get the total record count in this table and also the total amount for a specific field e.g. DMBTR in this table.
Do we have to use an internal table to transfer all the records of BSEG into the internal table to get the result?
We will give you reward points!

Hi Kevin,
Using SUM directly in SQL will NOT work for table BSEG because BSEG is pool table. You will get an ABAP error.
"Aggregate functions and the addition DISTINCT are not supported in field lists for pooled and cluster tables".
You need an internal table to transfer all data from BSEG and perform calculation for count and sum.
Concerning about performance running perhaps you can code something like this.
REPORT ZZFLTEST NO STANDARD PAGE HEADING.
TABLES: BSEG.
DATA: CURS          TYPE CURSOR,
      PACKAGE_SIZE LIKE RMCS4-MC_CM_PSIZE VALUE '10000'.
DATA: BEGIN OF I_BSEG OCCURS 0,
        BELNR TYPE BSEG-BELNR,
        BURKS TYPE BSEG-BURKS,
        GJAHR TYPE BSEG-GJAHR,
        BUZEI TYPE BSEG-BUZEI,
        DMBTR TYPE BSEG-DMBTR,
        SHKZG TYPE BSEG-SHKZG.
DATA: END OF I_BSEG.
DATA: TOT_DMBTR TYPE BSEG-DMBTR,
      TOT_REC   TYPE I.
SELECTION-SCREEN BEGIN OF BLOCK B01 WITH FRAME TITLE TEXT-001.
SELECTION-SCREEN SKIP.
PARAMETERS: P_SIZE LIKE RMCS4-MC_CM_PSIZE DEFAULT '10000'.
SELECTION-SCREEN SKIP.
SELECTION-SCREEN END OF BLOCK B01.
START-OF-SELECTION.
PACKAGE_SIZE = P_SIZE.
OPEN CURSOR WITH HOLD CURS FOR
SELECT BELNR BURKS GJAHR BUZEI DMBTR SHKZG
FROM BSEG
WHERE BELNR <> SPACE
    AND BURKS <> SPACE
    AND GJAHR <> SPACE
    AND BUZEI <> SPACE.
*Fetch internal table I_BSEG for every 10000 records.
DO.
    FETCH NEXT CURSOR CURS
    INTO TABLE I_BSEG PACKAGE SIZE PACKAGE_SIZE.
    IF SY-SUBRC <> 0.
      EXIT.
    ENDIF.
ENDDO.
CLOSE CURSOR CURS.
LOOP AT I_BSEG.
    TOT_REC = TOT_REC + 1.
    IF I_BSEG-SHKZG = 'S'.
      TOT_DMBTR = TOT_DMBRT + I_BSEG-DMBTR * -1.
    ELSE.
      TOT_DMBTR = TOT_DMBTR + I_BSEG-DMBTR.
    ENDIF.
ENDLOOP.
WRITE: / 'TOTAL BSEG-DMBTR:', TOT_DMBTR,
         / 'TOTAL RECORD:    ', TOT_REC.
END-OF-SELECTION.
Hope this will help.

Master-detail form in HTML DB

Is there any way to create a master form with multiple detail tabs on the same page? This can be easily done in Oracle Forms by creating a master block and several child blocks on the same form.
Thanks.

Andy,
The master-detail wizard generates only one detail tabular form or report. When using the master-detail wizard, youâre asked whether you want to edit the detail records on the same page as the master record using a tabular form, or if you want to display the detail records as a report with links to a form page that lets you edit the detail records individually. If you want to have more than one detail report on your page, you can easily do that by adding additional reports manually. However those reports canât be tabular forms, because you can only have one tabular form per page. So those detail reports need to link to form pages, where you then can edit your detail records.
Regards,
Marc
