APEX function documentation

I'm new to APEX and finding that some functions aren't documented, such as wwv_flow_custom_auth_std.logout (used for the logout URL) and the JavaScript popUp2 function (just to name a couple that I've run across in my learning).
Reading other forum posts has convinced me that the wwv_flow functions should not be used directly and that documented API functions should be used instead. So for example, APEX_CUSTOM_AUTH.LOGOUT should be used instead of wwv_flow_custom_auth_std.logout.
APEX API - http://download.oracle.com/docs/cd/E14373_01/apirefs.32/e13369/toc.htm
So my question is, why is the JavaScript popUp2 function not listed in the JavaScript API and how many other functions aren't documented? Do I need to spend time looking through source files such as apex_3_1.js?

Thanks for the thorough explanation. So the APEX API and APEX JavaScript API really do contain all of the functions that developers like myself should be using (I wasn't missing anything). And even though I see undocumented functions referenced in the APEX generated code, APEX JavaScript files, APEX PL/SQL, APEX books, and this forum, I'm advised not to use these functions in my own code since these functions are internal to APEX and may not be supported in future releases of APEX.
Thanks again.

Anyone found a simple method to publish an APEX function as a web-service?

V() function documentation

OK, I give up.
Where can I find documentation for the v() and nv() functions? And where can I learn about more functions like these?
Thanks,
-Ken

Hello,
The previous poster (Tyson) probably mix up between the v() function, which is a PL/SQL function, and the $v() function, which is a JavaScript function.
As far as I know there isn’t any official documentation about the v() and NV() functions, other than the following - http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10499/concept.htm#sthref167 .
In previous versions, there were some performance issues with this function, especially when using it within a select statement. You can search this forum for threads on this issue. In addition, Patrick blogged about the function, and even introduced a function of its own - http://www.inside-oracle-apex.com/2006/12/drop-in-replacement-for-v-and-nv.html

Where Do I find APEX Online Documentation?

Application Express documentation is pretty easy to find for the latest release, just go to the Application Express homepage:
http://www.oracle.com/technetwork/developer-tools/apex/overview/index.html
And then click on the Documentation Tab to see all the documentation:
Older releases aren't so easy to find - at least from the Apex home page - but a quick google normally finds them pretty quick. Here are some quick links to access them:
Documentation Archive - There is an actual page listing the archives for each release, which is linked to from the official documentation page, which has links to all the previous archives (I didn't know about the link at time of posting, but David pointed it out to me below). It is in a paragraph just below all the latest documentation links - currently: http://www.oracle.com/technetwork/developer-tools/apex/application-express/all-archives-099381.html
Apex 4.0.x (latest)
Apex 3.2.x
Apex 3.1.x
Apex 3.0.x
Apex 2.2.x
Apex 2.0.x
Apex 1.6.x
nb: These are just the releases I know about; I didn't include 1.5 in the list as there is no offical oracle documents that I could find, but you can find the user's guide and release notes hosted on stanford pretty easily.

On the documentation page is a link to Prior Release Archives ( http://www.oracle.com/technetwork/developer-tools/apex/application-express/all-archives-099381.html ) which lists all of the documentation going back to HTML-DB 1.6.
Oh, I didn't know about that. Thanks :-)

Function Documentation

I want to know what does this FM "MC_RATIO_UNIT_READ" do. I can't find any documentation or explanation related to this one both on sites and help on sap. If i meet this kind of problem again where can i look it up?

Overall I agree that documentation is far from spectacular in SAP, but you'll find at least some documentation in the functions that are released to the customer (like the BAPI... ones). Many function modules are also rather self-explanatory.
Quite honestly I just don't understand why would you want to spend time understanding in depth what this function does? The whole point of a function is exactly the opposite - it's a "black box" where you can put some values in and get some values back. Who cares what happens inside as long as it works fine? Certainly desire to learn is more than admirable but the effort seems to be rather misplaced in this case.
Are you not getting the right values back? Then maybe you need to put different values in or find a different function. If you don't know what values to put in then how about running 'where used'?

How to find BAPI function documentation without going into multiple screens

Hi Gurus,
How I am find the documentation of some function is I use transaction code /nBAPI. That takes me to BAPI Explorer. Then I select the system like "Sales and Distribution". Then I drill deep into the required function.
This works for all the functions those are inside some module, like SD. But the function that is not present in some module like RFC_SYSTEM_INFO, I just cant find it.
Is there a place in "SAP Easy Access"/SAP where you find the documentation of any function?
Thanks
Abbas

Hi Abbas,
You can open up the function module in SE37 and click on the documentation button on the application toolbar.

Apex function apex_util.get_blob with unexpected behavior

Hi Experts.
I've been building an Apex search application and hit a snag while testing the apex_util.get_blob download url. It appears the Download url is only valid in the session that it was generated. Meaning this. The url in Step 2 below now returns an "500 - Internal Server Error". But when it was first generated (i.e. select Download link in Apex app, the right click and select Copy Link Location) the same url below worked. Is there a way to fix this?
Here are my steps:
1) Upload a store a document using the Download syntax : DOWNLOAD:GPAP_PROJECT_FILES:FILE_BLOB:ID::FILE_MIMETYPE:FILENAME:UPDATED:FILE_CHARSET:Inline:Download.
2) with either FF or IE, when I select to cfopy the lijnk, e.g.
https://apex.oraclecorp.com/pls/apex/apex_util.get_blob?s=101780738579356&a=2853&c=35900184302057347654&p=19&k1=307565788455977950718535285815317923965&k2=&ck=23EE058993C510D8E30A6B23E12431E8&rt=CR
3) Result: If I paste this url into another browser window from the "same" session as the file, it works fine. But if I start a new browser instance/session, and paste the same url a "500 - Internal Server Error" results. Should this be possible, and if so, can you please share any suggestions?
Thanks a lot!
Mike

Hi Mike,
Did you consider creating a public procedure to download your file?
Here is a good blog that tells how to do this:
http://matthiashoys.wordpress.com/2013/02/22/http-404403-executing-apex-procedure-from-url-with-oracle-11g-xe/
You basically just create a procedure that generates the blog, and then you give it a grant to public.
Just remember to do a security check inside the procedure.

RFC function documentation?

Hi,
SAP Enterprise Widgets is new to me. I am able to follow guide to develop basic widgets to connect to SAP systems using RFC. My aim is to create a widget that displays customer support message number and closure survey result. I connected to CSS and I can see differnt functions. Is there any document on what each function does? What does each field represent?
E.g. In the SAP Widget Development guide it calls DevDB_ITBCMESS_GET function and ET_ITBCCREATED_OUT structure in it and MNumm ( Ticket Number) and KText ( Description) fields in that structure. How do I know which functions\ structures and fields represent what?
Also, there could be security constraints e.g. I cannot see tickets logged by other users, how do you go about getting permission/
Thanks in advance for your help.
Thanks

Apex Function API's and column aliases

Has anyone run into this? WHen I supply this simple query in a report page, the syntax is accepted:
select apex_item.text(1,c.claim_nbr)
from claim c, service_x m
where c.claim_nbr = m.claim_nbr
When I change it to this:
select apex_item.hidden(1,c.claim_nbr)
from claim c, service_x m
where c.claim_nbr = m.claim_nbr
I get this result:
1 error has occurred
query column #1 (APEX_ITEM.HIDDEN(1,C.CLAIM_NBR)) is invalid, use column alias

User,
What is your name?
I would have expected the error in both cases. Try:
apex_item.hidden(1,c.claim_nbr) AS column_aliasRegards,

URGENT: Extend EBS with APEX (new Tab Menu = Function/ html call to APEX)

Hello everyone,
we are trying to extend EBS with APEX applications:
- Created function XX with type = JSP (HTML Call = GWY.jsp?targetAppType=APEX&p=100:1)
If we add/ call this function on a standard EBS main menu, it works fine and calls the APEX page with the correct URL (configured on system profile "FND: APEX URL").
But we want to add these APEX functionality on a Level 2 Tab Page / EBS Subtab menu (Menu type = "HTML Sub Tab").
Is it possible to add the APEX page to this level?
I mean, add APEX page on a "frame" associated to the new EBS subtab menu (like a "region" on the EBS page) ?
Thanks in advance for any help or support.
AG.

A beginner question: How can I call an APEX page from outside

I want to mix APEX functionality and other enterprise tools.
Thus I wish to call by an URL an APEX page by transmitting the mandatory page argument and optionnal argument like an order number. I just couldn't found any information in the documentation about own argument in an URL
Any idea?

Multi Root Tree in APEX

Hey All,
I'm creating an APEX front-end for a currently existing forms application. My issue is that the document manager created for this application does not have a single root node. There are several folders that make up the original.
It does use the ID, PARENT_ID, DESCRIPTION hierarchy already.
However being a very dynamic application we don't control how many records that won't have parent ids.
Is is possible to create a tree with several Roots or rather no single root using APEX functionality?
Does anybody have any documentation on how this could be done using AJAX or other technologies within APEX if it cannot be done?
