Designing base VO for a page in create/update/view modes involving LOVs

Hi All,
We are developing a complete custom OAF page which is based on information in a single table.
The page will be used in create,update and view modes. 70% of the page fields are lov fields and hence I wanted to clarify my doubts before proceeding any further in development.
The page is based on a single table.
Example : XX_SUPPLIER_INFO(Columns : Supp_id,Supplier_trained_by_id,Service_manager_id,...etc).I created this as a EO based updateable VO
In the page "Supplier trained by" and "Service_manager" are LOV fields (messageLovInput style) that are based on plain SQL VOs.
Those LOV-VOs return displayable names and ids(key value) for those names and the IDs alone are stored in the base table(XX_SUPPLIER_INFO).
I am pretty sure of the above design will work for creation.
In update and view modes for the page will the lov field mapping help in automatically fetching the displayable names?
If not how should I design my Base page vo?
Any help on this is appreciated.
Thanks,
Haritha

Editing Oracle seeded files is not recommended as they are not upgrade/ patch safe. Read OTL impl white paper for your custom LOV requirements, They have explained well.

GP Design Time - what is the purpose of 'Create Object View' option?

We are running EP 7.01. When I am in the GP Design Time, and I click on the 'Create Object View' link, I receive the following error:
The initial exception that caused the request to fail, was:

What is the purpose of the 'Create Object View' option? I cannot find it in the documentation.

Hi Karen,
The Object Types are used to define the Parameters for the Callable Objects. We Can create the Object Views for the CAF Core Entity services or UME Pricipal Objects such as Users,Roles Groups etc. While creating the Object View we can select either of these and then we can create a view i..e. Select the required attributes from those Business Objects i.e. Entity Services or the Principals. Once we create the Object View, we can use them to define the Parameters for the callable Objects. While defining the parameters for Callable Objects, if you click the dropdown for 'Type', you'll see an entry 'Reference to BO'. If you select the entry, you'll see the list of Object Views you have created and you can select the Object View you want for defining that parameter. In short it means that you can create the Obect Views for the BOs i.e. CAF core Entity services and Pricipals. And then you can define the parameters for the Callable Objects with type 'Refence to BO' pointing to your object views.

Permissions required for an user to create a View in Oracle 10.2.0.1.0

Hi,
I am facing one serious issue with Oacle 10.2.0.1.0.
I have an user (Atlas) created with below permissions.
grant connect to atlas;
grant resource to atlas;
grant create public synonym to atlas;
grant select any dictionary to atlas;
grant query rewrite to atlas;
I will create my database schema on this user Atlas. All my scripts are executing properly with Oracle 9i and 10g version 10.1.0.2.0. But when it comes to Oracle 10g version 10.2.0.1.0 the views creation is throwing an error saying that Insufficient Priviliges.
I didn't get why this error is coming.
What previliges does an user should require for creating a view in Oracle 10.2.0.1.0 version?
I have installed Enterprise version of Oracle 10.2.0.1.0. Please suggest me with this.
Thanks
Rao

CREATE VIEW was taken away from connect or resouce in 10.2.x. It has to be explicity granted... Not sure what this has to do with XML per-se :)

Problem with creating "updatable" view. Any ideas?

Hello to nice people!
I'm trying to create plain, simple updatable view such as:
CREATE OR REPLACE VIEW v_admin_maint
(from_addrs,mail_invoice_addrs,auth_off,location_cd) AS SELECT
A.from_addrs, A.mail_invoice_addrs, A.auth_off,
A.location_cd FROM admin_maint A, sysusers B WHERE A.location_cd
= B.location_cd and B.user_id = USER;
TABLE admin_maint
from_addrs,
mail_invoice_addrs,
auth_off,
location_cd (PRIMARY KEY)
TABLE sysusers
USER_ID (PRIMARY KEY)
FIRST_NAME
LAST_NAME
LOCATION_CD
View works great as view-only, but I got an error on update
statement "ORA-01779: cannot modify a column which maps to a non
key-preserved table".
UPDATE v_admin_maint SET from_addrs = 'test' where location_cd
= 'HOME';
TABLE admin_maint does have PK and this column included into
VIEW.
Any ideas? Please advice.

You need to create a unique index on the location_cd column of
the sysusers table, then re-create your view:
SQL> ALTER TABLE sysusers
2 ADD CONSTRAINT sysusers_location_cd_uk
3 UNIQUE (location_cd)
4 /
Table altered.
SQL> CREATE OR REPLACE VIEW v_admin_maint
2    (from_addrs,
3     mail_invoice_addrs,
4     auth_off,
5     location_cd)
6 AS
7 SELECT A.from_addrs,
8         A.mail_invoice_addrs,
9         A.auth_off,
10         A.location_cd
11 FROM   admin_maint A,
12         sysusers B
13 WHERE A.location_cd = B.location_cd
14 and    B.user_id = USER
15 /
View created.
SQL> SELECT      column_name,
2              updatable
3 FROM        user_updatable_columns
4 WHERE       table_name = 'V_ADMIN_MAINT'
5 /
COLUMN_NAME                    UPD
FROM_ADDRS                     YES
MAIL_INVOICE_ADDRS             YES
AUTH_OFF                       YES
LOCATION_CD                    YES
SQL> UPDATE v_admin_maint
2 SET    from_addrs = 'test'
3 where location_cd = 'HOME'
4 /
1 row updated.

Query for Transaction number in Create Accounting = Draft Mode

Hi al!!
I run the Create Accounting program concurrent in my R12 instance in DRAFT MODE, and when the concurrent program finish i want to obtain the TRANSACTION number of the transactions in the XLA_AE_LINES table, how can i do that ???... it's for AP_INVOICES, AP_PAYMENTS, RECEIPT and CE Tables...
Thanks in advance..
Pablo.-

1 row in ap_invoice_distributions_all ------> 1 row in xla_ae_lines.xla_ae_lines will have more than one row. dr and cr has to be there for each journal entry.
I want to do a query that get lines from XLA_AE_LINES and then obtain the transaction number (AP_INVOICES_ALL.INVOICE_NUM) that was generated this line in the table.Check the link http://www.orafaq.com/node/2242
I know that this is possible to do using the XLA_ENTITY_TRANSACTIONS table... but when the concurrent is run in DRAFT mode no line are created in this table.The rows in xla_transaction_entities table will get created when the invoice is created. NOT after running accounting, which is much earlier.
Check the link http://www.orafaq.com/node/2243
Also some more details on draft, final accounting are available at http://www.orafaq.com/node/2240

Color for published page does not update

I built a web site in 2009.
I have just made changes to it in 2011.
I added 3 new pages, updated a few others.
I publish the site changes. Or I publish the entire site. Do each to MobileMe.
The updated pages colors turn from red to blue.
Then I want to keep a folder of the site, so I choose publish to a folder.
At this point, the updated pages turn red again.
I publish the site changes. Or I publish the entire site. Do each to a folder.
The updated pages colors turn from red to blue.
When I choose publish to MobileMe again,
without making any changes,
the same pages turn to red again as if they were changed.
And the same thing if I choose publish to a folder.
Why do they change? How can I fix this?

Yes I understand that.
But after it has been published once for each way and then I don't make any changes, they should not turn red and need to be published again. They should stay blue if I don't make any changes. Even if I switch the publishing mode.
I publish just the changes, then I publish the whole site. I send both to MobileMe. Then I switch modes. I publish changes and then the whole site to a folder. Everything is blue. Then if I switch back to publish to MobileMe, the few pages turn red again, after they had been completely blue after publishing them the first time. I don't think that should be happening. It acts like something is stuck.

Unable to retreive custom properties for WPC pages in TREX search result

Hi All,
We have created couple of custom properties "custom_news_heading" and "custom_news_abstract" which are indexable and made it available for all folders and documents.
In web pages folder in one of the WPC web site we have created few pages. In details screen for those pages we have updated those custom propeties with some text.
We have created an Index out of that web pages folder and able to see indexed count as same as the pages inside the web pages folder.
For that index the "Display Index Details" screen in TREX monitor is not showing up the custom properties - means TREX is not considering those custom properties even if have flagged it as Indexable.
Search result is returning the properties like "display name", contentlength etc. But we are not able to reterive the custom properties by customizing the Collection Renderer's Diaplayed properties.
Any advice please?
Thanks

Hi Dhaya/Scotts,
Please upload an image of ur layout setting and also the collection renderer in the
[Wiki|https://wiki.sdn.sap.com/wiki/x/IACnB] page that I have created for this thread...

Create a View with Aggregation Function (COUNT)

I've been looking up and down for a way to create a view with a few basic fields and some other fields containing aggregation function.
For instance:
To display a view that contain all the Contract Agreement and the corresponding count of the PO releases.
Agreement Nbr, Total PO releases
I need this view so that I can create a search help with this view.
I found something about the "CREATE VIEW" statement, but I don't have any idea how to use it.
Any helps toward this matter is very much appreciated, thanks.

Hello Aldern
I guess you have read about the SQL statement "CREATE VIEW". When we create a view in the dictionary this SQL statement is finally called to create the view on the DB. Thus, since we do not have any aggregation options in views you cannot achieve what you want using views.
The solution for your problem is to create a search help having a search help exit. Within the exit you can do your aggregation functions and add these values to the displayed search help data.
Regards
Uwe

Single page view mode in Acrobat Reader on android

Is there a way for a pdf to dictate the view mode used in Acrobat Reader on a smart phone? By default I believe it is set to continuous however I would like it to automatically change to single page when my pdf is opened.

Mark -
You are correct.
In Acrobat Reader on my PC, I'm highlighting text and then adding a sticky-note comment to it.
So, if I just insert a sticky note comment without highlighting the associated text in the document, I can see the sticky note when I view the document on my android device - - just tested this and it works!
OK - I can live with that, but it would be good if the combination of highlighting AND sticky notes were visible when viewin the document in Android - the highlightimg feature makes it clearer to what piece of text the sticky bote relates to. Hope it can be incorporated in a furure release.
Thanks for clarifying the situation for me.

Designer 2013 - Design Manager: Page layout created is not showing up in Designer

Hello everyone,
I greatly need assistance. I have wasted over 1/2 a day trying to fix this issue.
I have a site with a subsite. I'm customizing the subsite using the Design Manager. I've been through all of the steps and now I've created a Page Layout (step 6). I created the html and it generated the aspx. I have a drive mapped to the master page
gallery. The files are showing up in the mapped drive. However, when I go into Designer 2013 and click Master Pages, the files aren't there. This happened to me last week and then suddenly, almost magically if you will, the files were there. This was after
refreshing several times, closing Designer and opening it up. All the little tricks you have to use with Designer every now and then. So today I was repeating the process and the files aren't showing up again. I've been refreshing for 4 hours, closed Designer,
even rebooted. To no avail. I disconnected the mapped drive and reconnected. Nothing.
I have the correct permissions. I'm not only the site collection administrator but I'm also the SP Admin.
Assistance would be greatly appreciated.
Thanks,
Lisa

you have a subsite in a site collection •the publishing feature is activated in the subsite, but not in the site collection •you want to edit/add page layouts on the site collection level, to be used within your subsite •when you open the
site collection in SharePoint Designer, you can't see Page Layouts in the Site Objects panel You now have 2 options: you can either activate the publishing feature in the site collection (and the Page Layouts link comes back), or you can use the All Files
link and browse to the master pages and page layouts library (_catalogs > masterpage.) Either option will do, unless you really don't want the publishing feature in the site collection

How To Create Style Guides for Web Pages

I need to create style guides for websites. I will be provided with the assets (images and required measurements). It will be my job to create style guides using In Design.
I have never used In Design, but I am a member of Lynda and Total Training online. Neither seem to address simple style guides for websites. Both seem to address designing from scratch for print and newsletter creation.
Any links to tutorials? This seems straight-forward, but because I have never done it, I would appreciate direction.
Thanks!

I received a sample of what I'll be working on. Attached is one screenshot (blurred areas to conceal confidential info).
Overall, I will be given web page images (as seen below and as an original sized attachment) like screenshots.
I will be given measurements.
I will create a web style guide with text and the placement of images, and pinpoint where the objects are placed on the pages in pixels. e.g. Hero section - 80 pixels, padding - 40 pixels, etc. You can see this below in the (tiny, or see the larger attachment) text on the sides of the web page image.
The original designer also added some type of padding. You can see it below in blue at the bottom of the page. Is this the norm? How is that done?
Big Question: There are no pixels in InDesign. Are points equivalent, or should I set this (pixel notations) part up in Photoshop?
I hope this provides more details for you to help me, and I know this is a lot to ask. Thanks in advance!

To create home page which consists of menu for other pages in a tree format

hi, i'm using Jdev 11g, i want to create one home page which having a tree format menu for other pages ,plz tell me

Hi,
the tree structure must be defined in a tree model that you then associate as the value to the tree component. I think the best doc to start with is from Trinidada: http://myfaces.apache.org/trinidad/devguide/tree.html
Note that ADF Faces components base on Trinidad, so the docs can be used here as well. Also, while you are on this page, have a look at the XML Menu Model, which is a nice way of creating hierarchical structures in XML so the structure is not hard coded in a Java class
