Node Functions in XI, I am new to XI

Hi ,
i am new to XI, i need some documentation regarding Node Functions.

Hi,
.SplitByValue:
The SplitByValue() function is the counterpart to removeContexts(): Instead of deleting a context, you can insert a context change in the source value queue. You then receive this element for each inserted context change instead of a top node element. However, for this to be possible, the top node source field must be assigned a top node target field and minOccurs must be >0. You can insert a context change in the queue after each value, after each change to the value, or after each tag without a value.
2.RemoveContexts:
You use removeContexts () to delete all the top contexts for an element. This removes all top hierarchy levels, so that all elements of the target queue are assigned to a root element of the source queue.
Advanced user-defined functions can import either just one context into the input arrays, or complete queues. Make your selection by selecting or deselecting the Save Entire Queue in Cache checkbox in the function editor.
3.CreateIf:
CreateIf node function is used to create a node if true value is passed to it otherwise suppress it.
4.collapseContext
To remove the context in between the value and transfer only one value at a time
5.: useOneAsMany
First Input:
The value which is needed to be repeated.
Second Input:
It defines how many times the first input should be repeated.
Third Input:
It define when the context should be changed (on the basis of the required output

FUNCTION-BASED INDEX ( ORACLE 8I NEW FEATURE )

제품 : ORACLE SERVER
작성날짜 : 2004-08-16
FUNCTION-BASED INDEX ( ORACLE 8I NEW FEATURE )
==============================================
SCOPE
10g Standard Edition(10.1.0) 이상 부터 Function-based Index 기능이 지원된다.
Explanation
1. 개요
 Function-based index는, 함수(function)이나 수식(expression)으로 계산
된 결과에 대해 인덱스를 생성하여 사용할 수 있는 기능을 제공한다.
 질의 수행 시 해당 함수나 수식을 처리하여 결과를 가져 오는 것이 아니라,
 인덱스 형태로 존재하는 미리 계산되어 있는 결과를 가지고 처리하므로
 성능 향상을 기할 수 있다.
2. 제약사항
1) aggregate function 에 대한 function-based index 생성 불가.
(예 : sum(...) )
2) LOB, REF, nested table 컬럼에 대한 function-based index 생성 불가.
3. 주요 특징
 1) cost-based optimizer에 의해 사용됨.
 2) B*Tree / bitmap index로 생성 가능.
 3) 산술식 (arithmetic expression), PLSQL function, SQL built-in
function 등에 적용 가능.
 4) 함수나 수식으로 처리된 결과에 대한 range scan 가능
 5) NLS SORT 지원
 6) SELECT/DELETE를 할 때마다 함수나 수식의 결과를 계산하는 것이 아니라
 INSERT/UPDATE 시 계산된 값을 인덱스에 저장.
 7) 질의 속도 향상
 8) object column이나 REF column에 대해서는 해당 object에 정의된
 method에 대해 function-based index 생성 가능.
4. 생성 방법
 CREATE [UNIQUE | BITMAP ] INDEX <index_name>
 ON <tablename> (<index-expression-list>)
 <index-expression-list> -> { <column_name> | <column_expression> }
 예) CREATE INDEX EMP_NAME_INDEX ON EMP (UPPER(ENAME));
 CREATE INDEX EMP_SAL_INDEX ON EMP( SAL + COMM, empno);
 * Function-based index를 생성하기 위해서는 QUERY REWRITE 권한이
 부여 되어 있어야만 한다.
 예) GRANT QUERY REWRITE TO SCOTT;
5. Function-Based Index 사용을 위한 사전 작업
 1) Function-based index는 cost based optimizer에서만 사용 가능하므로,
 테이블에 대해 미리 analyze 해 주는 것이 바람직하다.
 그리고 init 파일에서 OPTIMIZER_MODE 를 FIRST_ROWS 나 ALL_ROWS 등으
로 지정하거나 HINT 등을 사용하여 cost based optimizer가 사용되도록
한다.
 2) init 파일에서 COMPATIBLE 파라미터 값을 8.1 이상으로 설정되어 있어야
한다.
 ( 예 : COMPATIBLE = 8.1.6 )
 3) session/instance level 에서 QUERY_REWRITE_ENABLED 값이 TRUE 지정
되어 있어야 한다.
 ( 예 : ALTER SESSION SET QUERY_REWRITE_ENABLED = TRUE; )
6. 예제
 1) init 파라미터에서 다음과 같이 지정
 compatible = 8.1.6 (반드시 8.1이상이어야 한다)
 query_rewrite_enabled = true
 query_rewrite_integrity = trusted
 2) SCOTT 유저에서 function_based_index 생성
 create index idx_emp_lower_ename
 on emp
 ( lower(ename) ) ;
 3) EMP table analyze
 analyze table emp compute statistics ;
 4) PLAN_TABLE 생성
 @ ?/rdbms/admin/utlxplan.sql
 5) Cost based optimizer 선택
 alter session set optimizer_mode = FIRST_ROWS ;
 6) Query 실행
 explain plan set statement_id='qry1' FOR
 select empno, ename
 from emp
 where lower(ename) = 'ford' ;
 7) PLAN 분석
 SELECT LPAD(' ',2*level-2)||operation||' '||options||' '||object_name query_plan
 FROM plan_table
 WHERE statement_id='qry1'
 CONNECT BY prior id = parent_id
 START WITH id = 0 order by id ;
 -> 결과
 QUERY_PLAN
 SELECT STATEMENT
 TABLE ACCESS BY INDEX ROWID EMP
 INDEX RANGE SCAN IDX_EMP_LOWER_ENAME
7. 결론
Function-based index는 적절하게 사용될 경우 성능상의 많은 이점을 가져
온다. Oracle8i Designing and Tuning for Performance에서도 가능한 한
Function-based index를 사용하는 것을 권장하고 있으며, LOWER(), UPPER()
등의 함수를 사용하여 불가피하게 FULL TABLE SCAN을 하는 경우에 대해서도
효과적으로 처리해 줄 수 있는 방안이라 할 수 있다.
Reference Documents
-------------------

Partha:
From the Oracle8i Administrators Guide:
"Table owners should have EXECUTE privileges on the functions used in function-based indexes.
For the creation of a function-based index in your own schema, you must be
granted the CREATE INDEX and QUERY REWRITE system privileges. To create
the index in another schema or on another schemas tables, you must have the
CREATE ANY INDEX and GLOBAL QUERY REWRITE privileges."
Hope this helps.

Is UDF required for this?!! or Can we manage with Node Functions?!!!

HI Gurus,
I have a requirement like below desc, Is UDF required for this?!! or Can we manage with Node Functions?!!!
Source File: ( File )
a) PO_TYPE
b) Style1
c) Style2
Note: Style1 leads to Headernode and Style2 leads to ChildNode, Style1 and Style 2 are interconnected.
Target File: ( Idoc )
a) Header Node ( EHDRNDE)
b) Child NOde ( CHLDNDE)
And my question is.... I have to populate Header Node and Child Node in target side on certain conditions of the source file. they are;
I) Whenver a different style1 comes in file...I have to create a Headernode for that in target file. Style1 can contain number of Style2 nodes with the same node. like
Ex:
i) Style1 -
Style2a, Style2b, Style2c
ii) Style1 ....... Style2aa, Style2ab.
For this above requirement, I have to create corresponding target nodes for Header ( Style1 ) and as well as for Child ( Style2)
for ex1: it should be one Header node in target and 3 corresponding child nodes
for ex2 : It should be One Header Node and 2 child nodes
For this requirement...can we use node functions....if it is...could you please help me.
....Stallin
Edited by: stallin xavier on May 1, 2008 4:18 AM

Hi,
You can do it by using node function as well as UDF also.
1) If your sequence is sorted and always come in sorted order only e.g. 1st come only style1 node and child node and then come all nodes from style 2 then u can use node function.
2) for parent node use collpse context then remove context.
3) for child node 1st differntiat according to your condition and then use split by value(value change)
4) If occurance of style1 node and style2 node is not fixed then you don't have any option you have to write UDF.
I think this will help you.

Rohit.

Node functions in Message Mapping

Hi,
Could someone help me with some good exercises for node functions such as splitbyvalue, collapsecontents, removecontexts.
I am a newbie to these functions and have absolutely no idea on how to use them. Would appreciate if someone could give very detailed examples to these functions in a step by step manner, so that I can create them just by following your instructions.
Any links to video presentations are welcome too.
Cheers,

Advanced functions,UDF's and node function

Dear all,
Can you kindly let me know about Advanced functions,UDF's and node function.Differences and Uses.
Also Let me know about the advantages,Disadvantages of Graphical,XSLT,Java,ABAP and ABAP XSLT mappings.
Thanks,
Srini

Hi,
The term Mapping means:
1. The transformation process, and/or
2. The transformation rules.
Independently from XI, you can distinguish two different mappings
Structure mappings transform entire message structures.
Value mappings transform values within messages.
Mapping Programs to Map Messages :
Message Mapping
Designed by using the graphical mapping editor of Integration Builder
Result: Generated Java Code.
Imported Archives
Import externally defined mapping programs into repository
Java mapping:
Implemented by using a specific interface
XSLT mapping:
Runtime supports XSLT processor
Java methods can be called from within a Style Sheet
ABAP Mapping
You can execute mapping programs in a sequence
The exchange infrastructure supports three types of mappings:
Message mappings that can be designed using a graphical mapping editor in the Integration Builder. As a result, Java code is generated from the graphical representation that is compiled before it can be executed on the integration server.
You can implement your own Java mapping by implementing a specific interface of the mapping API.
You can implement an XSLT mapping
For the latter two, there is no tool support in XI. It is expected that they are developed using external development tools. To make them available for the integration server, they have to be imported into the integration repository as JAR
files before (JAR: Java Archives).
Developers can even decide to combine the different mapping technologies:
Message mappings, XSLT mappings and Java mappings can be combined in a sequence by means of an interface mapping.
XSLT mappings can use java functions
Message mappings support user-defined functions that can use imported java packages of the same namespace.
In SAP XI, there is 3 types of mappings. Namely
XSLT Mapping
Java Mapping
ABAP Mapping
Here is the details of each mapping.
XSLT Mappings (ABAP Engine)
Interface descriptions are in the form of XML documents. XSL Transformation (XSLT) is a member of the XML family of languages. It describes how an XML structure is transformed into another XML structure.
Customers can develop an XSLT mapping by using the Transformation Editor of the ABAP Workbench. Such XSLT mappings are executed at runtime on the ABAP Engine of the Integration Server.
To simplify matters, this section refers to XSLT mappings of the ABAP Engine as transformation programs to differentiate them from XSLT mappings from imported archives that are executed on the J2EE Engine.
Features
XPath and <xsl:include>
You can define mappings using XSLT together with XPath. XPath is also a specification of the XML family. Using XPath you can address any node in an XML document. XSLT implements XPath expressions to select substructures of an XML document. Using templates in XSLT you can define the mapping rules for the selected substructures.
You can use the XSLT tags <xsl:include> and <xsl:import> to include predefined templates for substructures in a complete mapping definition. In this way, you can reuse mappings for data types.
Java Mapping
You can implement mapping programs in Java. To process XML documents, use Java API for XML Processing (JAXP), for example. The JAXP supports the Document Object Model (DOM) and the Simple API for XML (SAX). This gives you great flexibility for mapping definitions with Java.
Implementation Considerations
Java mapping programs are not permitted to be stateful. You are therefore not permitted to perform actions such as writing data to a database table during a Java mapping. The Integration Server cannot track such side effects. Therefore, if an attempt is made to resend a message that has not been received by the receiver, the data may inadvertently be written to the database twice in a Java mapping.
If you use JRE classes in your Java mapping programs then the same program restrictions apply as for Enterprise Java Beans (EJBs). For a detailed description of these restrictions, see the relevant EJB specification. It is important that you also refer to the information under Scope of Functions in Runtime Environment (Java Mappings).
The runtime environment for Java mappings has an mapping API. To use Java mapping, you must define a Java class that implements the Java interface com.sap.aii.mapping.api.StreamTransformation. This interface has two methods:
● public void execute(java.io.InputStream in, java.io.OutputStream out)
At runtime, the Integration Engine calls this method to execute a mapping. This method contains an input stream for the source document and an output stream for the target document as parameters. These streams are usually XML documents. You can import the substructures to be converted from the input stream and output the converted target document in the output stream.
● public void setParameter(java.util.Map param)
The Integration Engine transfers parameters to the mapping program with this method. It evaluates these parameters at runtime in the method execute(). This enables you to control the process flow of the mapping.
The transferred object that implements the Java interface java.util.Map contains seven key/value pairs as parameters. These correspond to corresponding fields in the message header. Apart from the MAPPING_TRACE constant, the value objects are of type java.lang.String. The key objects are defined in the class com.sap.aii.mapping.api.StreamTransformationConstants
ABAP Mappings
ABAP mappings are mapping programs in ABAP objects that customers can implement using the ABAP Workbench.
Features
An ABAP mapping comprises an ABAP class that implements the interface IF_MAPPING in the package SAI_MAPPING.
Exception: CX_MAPPING_FAULT
Applications can decide themselves in the method EXECUTE how to import and change the source XML document. If you want to use the XSLT processor of SAP Web AS, you can use the ABAP Workbench to develop a stylesheet directly (see XSLT Mappings (ABAP Engine)) rather than using ABAP mappings.
Runtime Constants
In ABAP mapping you can read access message header fields. To do this, an object of type IF_MAPPING_PARAM is transferred to the EXECUTE method. The interface has constants for the names of the available parameters and a method GET, which returns the respective value for the parameter name. The constants are the same as in Java mappings, although the constant MAPPING_TRACE does not exist for ABAP mappings. Instead, the trace object is transferred directly using the parameter TRACE of the method IF_MAPPING~EXECUTE
Example: Accessing a Runtime Constant
Method IF_MAPPING~EXECUTE.
Get mapping constant SENDER_SERVICE
data: l_sender_service type string.
l_sender_service = param->get( IF_MAPPING_PARAM=>SENDER_SERVICE ).
ENDMETHOD.

IDOC to FILE(xml) graphical mapping using node function createIf

Greetings All,
            My Scenario is Idoc to File(XML)
Target Structure is
                       MO_MAT_LAN....................(0: unbound)
                            LAN_KEY.......................(0 :1)

                            MAKTX..........................(0 :1)
initially i had mapped E1MAKTM----->MO_MAT_LAN but i dont want target node MO_MAT_LAN to be created when the SPRAS_ISO is equal to EN
I have tried using node function createIf but the node is geting created only once although the input stucture is having occurance more than 5.
Can anyone please help me to achive this.
Many thanks,
Rohit

U have to use:-
SPRAS_ISO mak the context to E1MAKTM compare (Use equals) it with Constant function EN out put to be given to If without else and in then Give E1MAKTM and map out put of If node to MO_MAT_LAN.

Setting to prevent "Function will be started in new session"

Hi all,
I'm focusing following problem / request.
User A is doubleclicking on a Inforecord number inside a puchase order position (ME23N). Now SAP is showing message MEPO014 (Function will be started in new session) and displaying master data of this inforecord in a new "window" (ME13). If the user has already 6 sessions open, he will get a error message "max. sessions ...!". So far so well.
Now the problem:
User B is doing the same, having already 6 sessions open and ME13 will be displayed in same session (window) where he doubleclicked the inforrecord (ME23N).
question:
is there a setting where i can influence the "new session" behaviour of SAP Gui?

Where is the node function:SOAP Lookup

Hi:
I can see the SOAP Lookup exists in SAP BASIS 7.11 when i define parameter in Operation Mapping.
But in Message Mapping,i can just find node functions of JDBC Lookup and RFC Lookup without SOAP Lookup,it can only be
used in UDF?
regards
Yu Ming

I think you are right, I could not find node function for SOAP lookup in PI 7.1.
I recently need to do SOAP lookup, so need to go for UDF only to create SOAP req message and parsing SOAP response and mapped to target field.

Hey,
1. remove context:
You use removeContexts () to delete all the top contexts for an element. This removes all top hierarchy levels, so that all elements of the target queue are assigned to a root element of the source queue.
Advanced user-defined functions can import either just one context into the input arrays, or complete queues. Make your selection by selecting or deselecting the Save Entire Queue in Cache checkbox in the function editor.
2. split by value:
The SplitByValue() function is the counterpart to removeContexts(): Instead of deleting a context, you can insert a context change in the source value queue. You then receive this element for each inserted context change instead of a top node element. However, for this to be possible, the top node source field must be assigned a top node target field and minOccurs must be >0. You can insert a context change in the queue after each value, after each change to the value, or after each tag without a value.
3. collapse context:
Using collapseContexts() puts the first values of all contexts into a context. Empty contexts are replaced with an empty string:
This can be useful if an upper-level node is to be created each time a lower-level node exists, for example. The function is useful in combination with the SplitByValue function.
4. Use one as many
You require the function useOneAsMany() if a field that only occurs once needs to be replicated as often as another field occurs in the outbound message so that the fields can be written to the target structure in pairs as a record.

5. Map with default
6.copyValue
You use CopyValue() for a frequently occurring element to copy the value of a position in the source structure and assign it to a target field. The value is copied each time the target field occurs in the target structure. However, it is copied a maximum of maxOccurs times
7.createIf
You use createIf() to create a tag in the target structure depending on a condition.
8.exists
You use this function to determine whether a particular source field exists in the XML instance to be processed. If it does, exists() returns the value true, otherwise it returns the value false.
9.Use
You use this function if you need to synchronize two queues of equal length with reference to their context change. The mapping runtime takes the values from the first queue, and the context change from the second queue. If the two inbound queues do not have the same number of values, the mapping runtime triggers an exception.

Example:
removeContext:
We use remove context to remove the context of a queue
A ->removeContext-> A
B B
C C
here each line under an alphabet denotes context change.
One thing about context change is it will not show you null values coming in input.
A ->removeContext-> A
C
C
in above example -- represents only context change no value in this place(null).
Collapscontext :
It works very much same way of removecontext but it also considers null values and gives [] for null values (if Context of Field is on its Preceeding parent otherwice it will work as remove context)
A ->CollapsContext-> A
[] (Blank value)
C C
One more chane is if there are multiple values in a context then it will only select first value from that queue
A ->CollapsContext-> A
D B
B C
C
As you can see in above example A & D falls under one context hence D is Removed
Split ByValue :
Used to Change the Context of Input
it has three options in it
1)each value
2)value change
3)emptyValue
The link given by Rohit is Self Explanatry for this .
FormateByExample :
it changes the Context of input1 as per the Context of Second input but the number of values in both the input must be same .
eg.
Input1 Input2 ->FormateByExample-> Out
A P A
B Q B
C R C
As you can see Context of input1 is Changed as per input 2
Sorry Guest Seems To Be Some Problem With Formating
Give me you Email ID Will Send You in Proper Formate
reward points if useful.

Node functions in UDF's

hi sdners
plzz provide me the basic concept how to use node functions in UDF's
thnx in adv

removeContexts:
for (int k = 0; k< var1.length; k++){
if (! a[k].equals(result.CC))
result.addValue(a[k]);
I leave you the other function as exercise
