HOW TO CREATE A GLOBAL USER DEFINED FUNCTION

Hi Expert,
I'd like to know if there is a way to globalize a user defined function?
I'd like to reuse a user defined function (e. g. DeleteLeadingCharacter) in several scenario/SWC instead of recreated it from scratch everytime - Is it possible?
Thanks

NO you cannot not reuse one UDF not even in other namespace even in the same namespace in diff Mapping programme.
UDF is liminted to GraphicalMappingProgramme that you created you cannot reuse it in other MappingProgrammes.
Like your MM =A has function getMyName
you can use it in MM=A but if you want to use it in MM=B then u cannot.
So its not possible in XI or PI.
But it is possible in new release PI 7.1. That says you can write UDF and can reuse in any MM programme.
Thanks
Farooq.

How to use StreamTransformationException in user-defined function?

Hi,
I'm doing a DBLookup (using Java pgm in one of my Imported Java archives) for populating one of the fields in message mapping. If the DB connection fails, I want to terminate the mapping by throwing a StreamTransformationException from within a user-defined function.
I require urgent help in this regard.
Thanks in advance.
Regards,
Sridhar Rajan N

Hi,
I had the same problem. I failed to find the way how to throw a StreamTransformationException in my user-defined function. But I used another exception: NullPointerException. Yes, I know, this is not an elegant solution...

Creating Index on user defined function

Does anyone know if you can create an index on a user defined, or system defined function like LOWER or UPPER in Oracle 8i?

According to Steve Yam's previous post:
DO you turn on the QUERY_REWRITE_ENABLED within session or instance? You need to
have this to utilize function based index in query.
Besides, Oracle may still use FULL TABLE SCAN if your table size is not big enough for
using index search. Determine number of blocks occupied by the table and determine
whether you really gain from the index.

How to create instance of user defined suite

I have create one user defined suite interface (ISuite) and inherite it to IsuiteASB and IsuiteCSB . The purpose of creating user defined suite is to provide hyphenation for selected text. I want to add a method which will detect whether a text has been selected by user or not , if selected then I am calling one hyphator function. I am not able to create an instance of user defined suite . I am using following syntax: in UpdateActionState I am using InterfacePtr<ISuite>suite(ac->GetContextSelection(),UseDefaultIID()); in one user defined method I am using InterfacePtr<ISuite>suite(Utils<ISelectionUtils>()->GetActiveSelection() , UseDefaultIID()); Both calls unsuccessfull. Which Interface I should use to detect whether Text has been selected by user or ITextUtils or any other. Please tell me the preoper way to create interface suite and create instance of it. Thank you.

I've seen this wording before ... Wait -- you must be referring to the SDK. Better post your question in the SDK forum, we're just helpless end-users, and in this case, clueless as well.

How to create custom(or) user defined component in SAPTAO

Hi,
Please provide me some document or steps on how to create custom component in sap tao.
Thanks a lot in advance.
Regards,
Sudha

Hi,
If you want create any custom components, you should use SAP QTP to create it.
Here are the simple steps:
i) Go to QTP -> Click on New - > Select Scripted Component - > ((Select SAP_Doc) area (i.e. whatever application area you have created for SAP TAO installation)) -> Record or Write a script based on your requirement & save
ii) Go to QC -> BPT -> open above component and insert the parameters and call these values in QTP script level (either way you can do)
iii) Create a datasheet and declare the parameters in datasheet and call this sheet whenever you have required.
Good luck.

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?
Thank you.

User-Defined Function and Context Manipulation

Hi Mapping Gurus, I need your help.
I have a user-defined function and one of my input parameter (c) is in a loop (EDI segment). So one, if I execute my function I get:
Exception:[java.lang.ArrayIndexOutOfBoundsException: 0]
If I change the context or use the remove context node function its working but its always taking the first row in consideration since I'm using c[0] . Here is the logic:
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[0]"'";
So since c is an array [], I have tried different logic to get to the right row.
1- I tried using another parameter (e) to pass a counter or an index to my function. So each time it's looping, it's passing a new value to the function but Im still getting the first row and Im not to sure why?
int G = Integer.parseInt(e[0]); // e[] = My counter field
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
2- I tried using a parameter stored in the container:
String Num;
Num = (String)getParameter(counter);
if (Num == null) G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Num = "" + G;
setParameter(e[0], Num);
and Im still getting the first one, look like its using a different container each time its looping so the Value is always the same?
4- I created a new user-defined function with the container logic, then its working but Im back to the same problem in my main function, its only looking at e[0] for my counter all the time.
5- I tried using the Seeburger Java Variables and guess what in the main fonction, as new UDF,... and guess what, same result!
So anybody out there that was able to get UDF's working into a multiple context scenario?
Am I missing something?
I will reward points and beer for any help!

This is one of the text with passing a counter to the function to try to go to the right row in the array since I'm doing a remove context and I'm getting all the d_234's:
public void ReadTable(String[] a,String[] b,String[] c,String[] d,String[] e,ResultList result,Container container){
int G = Integer.parseInt(e[0]); // My counter
String var;
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
Now this one was with the internal container logic:
int G;
String DBTABLE = a[0];
String lookUpField = d[0];
String Num;
Num = (String)getParameter(e[0]);
if (Num == null) G = 0;
else
G = Integer.parseInt(Num);
G = G + 1;
Num = "" + G;
setParameter(e[0], Num);
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
And now with the Seeburger Variables:
int G;
try {
VariableBean be=VariableFactory.getVariableInstance("");
G = Integer.parseInt(String.valueOf(be.getStringVariable("yves")));
} catch (Exception f) {
throw new RuntimeException(f);
String DBTABLE = a[0];
String lookUpField = d[0];
String WHERE_CLAUSE = "A"" = ""'"b[0]"'"" and B = ""'"c[G]"'";
try {
G = G + 1;
Num = "" + G;
VariableBean be=VariableFactory.getVariableInstance("");
be.setStringVariable("yves",Num);
catch (Exception f) {
throw new RuntimeException(f);
All 3 logics were returning always the first row or a counter of 1 if the logic is in the main ReadTable function.

Calling user defined functions through OBIEE

Can anyone tell me how I can call the user defined functions on database through the new BI tool.
The idea is to collect certain parameters through the prompt when launching the request, the function is supposed to pick up the parameters, make a certain calculation, and return a value.
I wrote the function, I just need help over how to call the function through the BI tool - that was pretty easy in the old Discoverer.
Thanks.

Hi Kresimir ,
You can use EVALUATE function to call a user defined function.
EVALUATE('FUNCTIONNAME(%1,..)' As DATATYPE,parameter1,...)
Here DATATYPE is the returntype of function.
Hope this will help.
Thanks

Hi Eric,
I have a Proxy service it reads mfl data and transform to some other schema.In this Transformation one element data is taken and we have to manipulate that data
based on the incoming value and return .For this process i took one function and i have to check weather it contains some symbols like ^,~ so i used contains function of
String with and with out prefix with if else condition it gives error "Unexpected token if"
declare function insp:buildReferenceRange($inRange as xs:string)
as xs:string
let $low:=""
