how many types of user defined functions are there?

Hi Ramakrishna,
A user-defined function is only visible in the message mapping in which you created it. You can insert the function in the data-flow editor as a standard function by using the User-Defined function category.
You can use the following user-defined functions:
1.Simple functions, which can process individual field input values for each function call. Simple functions therefore expect strings as input values and return a string.
2.Advanced functions, which can process several field input values for each function call. You can import either all field values of a context or the whole queue for the field in an array before calling the function. For more information, see Advanced User-Defined Functions.
    go through :

     Advanced user-defined functions, which can process more than just individual field values.Instead, you can import a complete context or an entire queue for a field as an array before your function is called

How to use a user defined function in XI

Hi Experts,
I would like learn how to use a user defined function in Xi during mapping . Is there any step by step on that.
Besides during when me make communcaton channels I see the following tabs...Paramters ..Identifiers ...Module...
The module that is given here ...where and how it is used.

Hi,
You can write UDFs in java in Graphical mapping to enhance your XI Graphical mapping functionality
The steps for doing it would be:
1. Click on Create New function Button found on Bottom left corner on your XI Mapping window.
2. Write your java code.
3. Run the Mapping Test as usual.
>>The module that is given here ...where and how it is used.
The adapters in the Adapter Framework convert XI messages to the protocols of connected external systems and the other way around. When doing so, some
functionality might need to be added specific to a situation which is possible with the use of custom modules.
Typical example would be validation of file content when using a File Adapter or modification of the message payload to a common content structure which is not supported by any of the standard SAP modules.
An Adapter module is developed as an Enterprise Java Bean and is called locally by the Adapter.

How to use a user defined function in where cluase condition

Hi,
I have designed a query by selecting some columns in the tables and some columns are retrieved directly from table and some columns are passing to a user defined function. Now my requirement is i need to use that user defined function result in oracle where condition clause.
Ex : select marketing_user_id,get_name(marketing_user_id),item_id,get_item_name(item_id),get_country_name(country_id),
from
where get_item_name(item_id) in ('x','y','z')
and get_country_name(country_id) in ('India','America','China');
When am i trying the query by above format i am getting the wrong resultset.
BR,
uma

I am not sure why your getting the wrong results but you should seriously reconsider the approach your are taking. Using functions like this is very ineffecient and should be avoided at all cost.

How can I find user defined functions in oracle

Hello All,
I need to find out what are the user defined functions available in my schema?
Please let me know on what system tables shall I query and find out the user defined functions?
Thanks,
Milind.

Thanks Satish,
One more query. Can I find what are the parameters that needs to be passed?
Here is what I have to do..
I have to find all the accessible user defined functions. If I select one of them in my UI, I need to show the parameters used in the respective function.
Please let me know if these parameters are stored anywhere..
Thanks again,
Milind

How to implement a user-defined function in a mathscript node

I am trying to use a mathscript node that includes self-defined functions, but I always get an error. I tried to run an NI-example: MathScript using Riemann Zeta.vi ,and I got the same error I get when I run my own programmes:MathScript Node'MathScript Node' (zeta): User-defined function contains an error. I didn't change anything in that example, so what could be wrong?

Try the Mathscript forum instead. Good luck.
(Maybe start reading this, for example)

How to distinguish the User-Defined-Function from Oracle Build-In function

Hi Friends,
I could get the function list form all_objects table by the SQL:
select * from all_objects where object_type = 'FUNCTION'
but there is no column in all_objects specify the function is build-in or user-defined.
But I found in SQL Server there is a column "is_ms_shipped" in the sys.all_objects table. This column will specify the object is build-in or user-defined. I want to get the equivalent column in Oracle but failed.
Could anyone tell me how to solve this problem?
Thanks,
Ricky

Thanks Pavan.
But if an user connects to database using "conn /as sysdba" syntax and creates a function. This user-defined funtion goes into the "SYS" schema also. I know it is not the best practise to create objects using sys user so I think your solution is right.

Ricky

How many display options for Web Apps are there?

I know this is going to sound stupid,
But are there only 2 ways to show web apps?
Basically - I want to get links to auto populate on one web app, pulling just links to another web page (this web page is one of the fields in another web app), but automatically updated when the category of the "linked to" web app has another product linked to it.
I know what that reads like!
The only thing is - these are separate web apps.
The alternate/backup view of the first web app looks like this:
Currently - the user has to manually add the links like this:
Which is not ideal - I just want them to dynamically populate on the fly.
Is this possible?
Cheers, Dave

Funny you say that - as the most obvious things appear in your brain immediately after posting a question... Will see how that works...

How to develop a user defined function to convert XML to Base64Binary

Hello,
I am trying to develop a solution in which I need to convert XML into Base64Binary so that I can then write this Base64Binary opaquely to a file (as opaque data is nothing but Base64 encoded data)
So, I want to develop a flow in which:
*File Adapter (read file based on some XSD) ----{color:#99cc00}XML{color}-----> BPEL/ESB input ----{color:#99cc00}XML{color}--------->Transform ----{color:#99cc00}Base64Binary{color}---------File Adapter that writes files opaquely*
{color:#000000}
What should be the signature of such a function. How I can pass the input to it.
TIA
{color}

Think i got something here How to convert String to base64Binary in BPEL process
but its BPEL all the way, how to get hold of input in an ESB process?

you advanced user defined functions are now known as
Enhanced Functions (Cache = Context or Cache = Queue)
From Help -
+Features
Depending on which values are available in the cache for a user-defined function, different functions are available:
·        Simple Functions (Cache = Value)
This function type can process individual input values of a field for each function call. Therefore, simple functions expect strings as input values and return a string.
·        Enhanced Functions (Cache = Context or Cache = Queue)
This function type can process multiple input values of a field for each function call. Before you call the function, you can either import all the field values of a context or the whole queue for the field in an array.+

User - defined functions for calculating the taxes of state and country

hi expects,
how can write user-defined function in message mapping in which i want to calculate the states taxes (2500) and country taxes (5000) and give the result as grand total in output.please help me?

Hi,
Activities
1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
graphic is explained in the accompanying text), which is located on the lower left-hand side of the
screen. In the menu, choose Simple Function or Advanced Function.
2. In the window that appears, specify the attributes of the new function:
Name
Technical name of the function. The name is displayed in the function chooser and on the data-flow
object.
Description
Description of how the function is used.
Cache
Function type (see above)
Argument Count
In this table, you specify the number of input values the function can process, and name them. All
functions are of type String.
3. In the window that appears, you can create Java source code:
a. You can import Java packages to your methods from the Imports input field, by specifying them
separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
all message mappings require these packages and therefore import them. You should be able to
access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
package under Import. In other words, you do not have to import it as an archive into the Integration
Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
In addition to the standard packages, you can also specify Java packages that you have imported as
archives and that are located in the same, or in an underlying software component version as the
message mapping.
b. Create your Java source text in the editor window or copy source text from another editor.
4. Confirm with Save and Close.
5. User-defined functions are limited to the message mapping in which you created the function. To
save the new function, save the message mapping.
6. To test the function, use the test environment.
The new function is now visible in the User-Defined function category. When you select this category,
a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
function to the data-flow editor, choose the arrow next to the button and select from the list box
displayed.

Need help with user defined function

Hello SDN,
I need some help with a user-defined function. My source message contains multiple
generic records (1000 char string), and my target message is 1 header record,
then multiple generic records. See description of source and target messages below:
Source:
GenericRecordTable 1..unbounded
    Row (1000 char string)
Target:
Field1 (char5)
Field2 (char5)
Field3 (char5)
IT_Data
    GenericRecordTable 1..unbounded
      Row (1000 char string)
Basically, what I need to do in my user defined funtion is to map the first record
in my source record to the 3 header fields, then map all of the rest of the records
(starting from line 2) into the GenericRecordTable.
Can someone please help me with the code for the user defined function(s) for this
mapping?
