Advanced Mapping question.
All,
we have 2 input messages, that need to be mapped into the output message.
<source1>
<response><id>1</id><cat>prodid</cat><value>PRD01</value></response>
<response><id>1</id><cat>name</cat><value>Name01</value></response>
<response><id>1</id><cat>price</cat><value>20.00</value></response>
<response><id>2</id><cat>prodid</cat><value>PRD02</value></response>
<response><id>2</id><cat>name</cat><value>Name02</value></response>
<response><id>2</id><cat>price</cat><value>30.00</value></response>
</source1>
<source2>
<product><id>1</id><prodid></prodid><isbn>isbn1</isbn><name></name><price></price></product>
<product><id>1</id><<prodid></prodid><isbn>isbn2</isbn><name></name><price></price></product>
</source2>
The target is exactly similar to source2 message. But the values of the nodes <prodid>, <name>, <price> needs to be populated from source1 message by matching the <id> and node name.
<target>
<product><prodid>PRD01</prodid><isbn>isbn1</isbn><name>Name01</name><price>20.00</price></product>
<product><prodid>PRD02</prodid><isbn>isbn2</isbn><name>Name02</name><price>30.00</price></product>
</target>
How can we do this using Advanced UDF?
Thanks
Check the following SAP Help link. It has a similar example.

Advanced mapping from IDOC to SOAP with reversed 3 level context change
Hi everyone.
I am having a though time mapping the HRMD_A01 IDOC into a SOAP message. The reason is that the reciever expects an xml structure where the root node is cost center instead of employee which is the case in the IDOC.
Mapping from:
IDOC (1..1)
E1PLOGI (1..unb)
SEGMENT (String)
OBJID (String)
E1PITYP (1..unb)
E1P0001 (1..unb)
SEGMENT (String)
KOSTL (String)
To this structure:
List (1..1)
CostCenters (1..unb)
KOSTL (String) ----> Mapped against KOSTL above
Employees (1..unb)
OBJID (String) ----> Mapped against OBJID above
I expect several occurances of E1PLOGI which states multiple employees sent in the IDOC. I also expect several occurences of E1P0001 containing cost centers.
My conclusion is that I need an advanced mapping and I have created one which collects all KOSTL for the IDOC context, deletes duplicates, and creates the CostCenters segment. This is now working. But my problem is that I can't create the employees segment in the right place. They are only created once under the first CostCenters node.
Here's the java-code for mapping between KOSTL and CostCenters/KOSTL:
public void costCenters(String[] var1, ResultList result, Container container) throws StreamTransformationException{
Set set = new HashSet(Arrays.asList(var1));
String[] array2 = (String[])(set.toArray(new String[set.size()]));
Arrays.sort(array2);
for (int i = 0; i < array2.length; i++) {
result.addValue(array2<i>);
Any ideas on how to proceed?
Best RegardsHi,
Do the mapping like below.
UDF should be select as context.
List (1..1)
CostCenters (1..unb)
KOSTL (String) ----> Mapped against KOSTL above
Employees (1..unb)
OBJID (String) ----> Mapped against OBJID above
Mapping:
KOSTL(RightSelectChange the context to E1PITYP)--UDF--Removecontext--CostCenters
KOSTL(RightSelectChange the context to E1PITYP)--UDF--SplitbyValue(Each Value)--KOSTL
constant---Employees
OBJID----------------------------------------------Use One As Many---SplitByValue (EachValue)----------OBJID
KOSTL(RightSelectChange the context to E1PITYP)--UDF---
KOSTL(RightSelectChange the context to E1PITYP)--UDF---

CRMXIF_REL_SAVE_M01 - Mapping Question
Hello All,
I have a mapping question, hope some one can answer my question. Please see the link first and the see my question
http://www.flickr.com/photos/8764045@N06/4265246260/sizes/o/
I'm mapping the CRM IDOC to the JDBC Call. I have small problem here. All the target fields are Mandatory 1..1 .
I will explain with an example:
I have field from source E102BUS_EI_STRUC_TEL_DATA/COUNTRY mapped to target field.
I used Map With Default so that even if the values are not there frm the source the target field will be mapped with blank.
But the problem is the parent node for E102BUS_EI_STRUC_TEL_DATA is E102BUS_EI_BUPA_TELEPHONE is 0.999999 , so sometimes that segment is not coming. In this case Map with Default won't work. Map with Default willl work only if the Parent node is present.
If you ask me to do Exists node function on E102BUS_EI_BUPA_TELEPHONE and then apply Map with Default, then even this won't work.
Apologize if I confused you guys. Please let me know if you need more clarification.
Thanks!
Raj.Hi Raj,
Try to do a mapping like this
E102BUS_EI_STRUC_TEL_DATA(context E102S_EI_BUPA_TELEPHONE_CON)--mapwithdefault-->then
E102BUS_EI_BUPA_TELEPHONE-->exists------------------------------------------------------------------>if---->splitbyValue
let us say this output (the output of splitbyvalue) as 'VALUE'
VALUE-----------------------------------------------> then
VALUE|-->count--->greater----------------------->if----->targetField
Constant(0)----> Constant(blank)-->else

Use cache parameter as Context.

//write your code here
String c = "";
int i;
for(i= 0 ; i < a.length; i++)
c = c + a<i> ;
if(i != (a.length-1))
c = c + ",";
result.addValue(c);
A(src)-->removecontext->UDF--->A(tgt)
B(src)--->removecontext->UDF--->B(tgt)
C(src)--->removecontext->UDF--->C(tgt) -
Mapping question: How to display only hole numbers..??
Hi all
I have 3 fields in my message mapping where I need to convert them to hole numbers. This includes Invoice amount, Brutto and Netto weight. If Invoice amount says '2300.30' in my IDoc it should be '2300' in the xml document. If amount says '2300.70' result should be '2301'in my xml document. The same logic should be applied to the 2 weight fields.
Thanks in advance
Peterhi Peter,
have you tried using <b>round</b> function?
it's a standard function from the arithmetic functio group in the message mapping
BTW
with this function:
2300.30 gives 2300
2300.70 gives 2301
tested
description:
round
O = integer value back that is closest to the value of argument I. Corresponds to the Java function java.lang.Math.round().

Hi,
I'm working with two classes Car and Customer. The Car class has a Vector of Customers and the Customer class has a Vector of Car. Both are related by a many to many mapping.
I have noticed that I have to set one of the vector to read only to avoid the error message "More than one writable many-to-many mapping can not use the same relation table" in the mapping workbench.
I can understand that but is there a way to work around, I mean to be able to add a car to a customer and add a customer to a car with the both vectors?
Is there something to do with the cache?
I use Vector for the collection or Map class, have I to do otherwise?Hello Vladislav, I understand your first question in this thread, but I'm not sure I follow the rest, so let me respond to your first post:
"I have noticed that I have to set one of the vector to read only to avoid the error message "More than one writable many-to-many mapping can not use the same relation table" in the mapping workbench.
I can understand that but is there a way to work around, I mean to be able to add a car to a customer and add a customer to a car with the both vectors?"
The issue here is that with a Many to Many mapping the mapping is responsible for writing to the association table. So, you have a "CAR_CUST" association table. Imagine you add a Car "101" to a customer "501" and the requisite customer "501" to that car "101" in your object model. Then the association table should only be updated once, with an entry of "101, 501". But since the M-M is mapped in both directions, you need to tell TopLink which of these to consider as the "master" when updating the database.
If you didn't make one of the M-M mappings "read only", then TopLink would insert "101, 501" twice in the association table, and then at a later date you would see that the customer 501 had two 101 cars!
We do have a feature that allows for TopLink to maintain bidirectional relationships such that if you add or remove a target from one relationship, TopLink will automatically add/remove it from the opposite direction. In my opinion this is lazy programming! A good Java developer should insist on keeping his model up to date on his own. This feature was added because it's part of the EJB spec, not necessarily because it's a good idea ;)

Hello,
I have a rather simple question regarding a mapping.
Lets say my input message is as following:
<mes1>
<seg1>
<name1>Peter</name1>
<street1>HighCrt</street1>
</seg1>
<seg2>
<name2>Vlad</name2>
<sub2>Trickst</sub2>
</seg2>
<seg2>
<name2>Rinaldo</name2>
<sub2>fiave</sub2>
</seg2>
</mes1>
My output should be:
<out>
<put>
<name>Peter</name>
<name>Vlad</name>
<name>Rinaldo</name>
</put>
</out>
So my output field "name" should created in case I have a "name1" field in the source message and additionally it should be created for every "seg2" element that is present in the source message and it should be filled with the value of "name2".
How can I in the mapping trigger that the "name" element of the output message will be generated for each of the two described elements of the source message?
Best Regards,
PeterHi,
Could be possible using user defined function.
Create a user defined Function with cache = context
public void createNodeName(String[] a,String[] b,ResultList result,Container container){
if ( a.length > 0 )
result.addValue ( a[0] ) ;
for ( int i = 0; i < b.length; i++ )
result.addValue ( b<i> );
in Mapping use
1. name1 as first argument
2. name2 with removeContext as second argument -
Hi,
I have few basic questions regarding mappings.
1) I think we can do everything by using Graphical Mapping. Then what is the purpose for Java, XSLT and ABAP mapping? Please give me an example for this...
2) Which mapping will give better performance? Is there any comparison document available in SDN?
Appreciate your help!
Thanks,
Vivekhi,
Mapping Techniques
XI provides 3 standard ways of interface mapping between source and target.
Graphical mapping
Java Mapping
XSLT Mapping
Two more additional mapping types can be activated in XI by making changes to the exchange profile. Those two mappings are
ABAP mapping
XSLT mapping with ABAP Extensions
Graphical Mapping
Graphical mapping is a common approach followed by everyone for generating desired target structure. It involves simple drag-n-drop to correlate respective nodes (fields) from source and target structure. It hardly involves coding. (Exception - User defined functions). But sometimes with graphical mapping it is difficult to produce required output. For example ... text/html output, namespace change, sorting or grouping of records etc.
ABAP Mapping
A person comfortable with Object Oriented ABAP can go for ABAP mapping instead.
Java Mapping
Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.
SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exaclty easy to develop either.
XSLT Mapping
One can also think of Java mapping as another option but it is a bit complex and required knowledge of Java. In such cases, XSLT mapping can be the best approach to meet the requirements.

Hi,
I am trying to get my head around ABAP mappings and have a few questions.
In the below code sample which I find in every example and blog it talks about specific steps -
*initialize iXML, * create iXML factory object, * create streamfactory object, * create input stream object, * initialize the input xml document, * parse the input xml document
In these steps the code is always exactly the same so my question is are these just standard steps that are implemented every single time an abap mapping is used and hence only standard lines that never have to be changed or will they be different depending on the mapping.
I am trying to work out where I will begin my coding.
So would somebody be so kind as to give me a brief explanation of the above mentioned steps.
Thank you
METHOD if_mapping~execute.
* initialize iXML
TYPE-POOLS: ixml.
CLASS cl_ixml DEFINITION LOAD.
* create iXML factory object
DATA: ixmlfactory TYPE REF TO if_ixml.
ixmlfactory = cl_ixml=>create( ).
* create streamfactory object
DATA: streamfactory TYPE REF TO
if_ixml_stream_factory.
streamfactory = ixmlfactory->create_stream_factory( ).
* create input stream object
DATA: istream TYPE REF TO if_ixml_istream.
istream = streamfactory->create_istream_xstring( source ).
* initialize the input xml document
DATA: idocument TYPE REF TO if_ixml_document.
idocument = ixmlfactory->create_document( ).
* parse the input xml document
DATA: iparser TYPE REF TO if_ixml_parser.
iparser = ixmlfactory->create_parser(
stream_factory = streamfactory
istream = istream
document = idocument ).
iparser->parse( ).Hi,
The above lines you mentioned deal with initialization of the iXML parser for parsing through the XML payload, so they would remain the same for all mapping where you are parsing the input payload.
The coding for you specific mapping will begin after this, something like :
* Implements the DOM generating interface to the parser
iparser->parse( ).
emp_node_collection = idocument->get_elements_by_tag_name_ns( name = 'Order' ).
emp_node_length = emp_node_collection->get_length( ).
emp_node_iterator = emp_node_collection->create_iterator( ).
where you start reading the xml node values.
Hope this helps.

Ramesh,
I hate to keep bugging everyone but i have another question.
I am trying to transform data into an X-12 856 document (outbound). I have most of the looping and everything working. My only issue is how do you handle the parent child relationships in the HL01/02 ? Since xpath does not let you increment a variable how can you keep the count of the HL loops let alone tell the HL02 (parent's HL01) We are using a SOPI scenario and the items need to be subordinate to the appopriate pack level.
I really appreciate all the time and awnsers you have given me so far :)
Thank you in advance,
JadenHi,
There is a way to handle x=x+1 in XSLT....here it is..assume u want to sum all the elements of an arraylist in an XML...create a temporary variable(TransCountSumVar) and do a foreach and group them in one more variable (Transactions_Count2)
<xsl:variable name="TransCountSumVar">
<xsl:for-each select="/ns1:TotalDate/ns1:price">
<Transactions_Count2>
<xsl:value-of select="number(ns1:price)"/>
</Transactions_Count2>
</xsl:for-each>
</xsl:variable>now get the sum of those in Transactions_Count2 as follows
<xsl:variable name="TComp" select="sum(exsl:node-set($TransCountSumVar)/Transactions_Count2)"/>where Tcomp is another variable with holds the final sum and be sure to the the namespace xmlns:exsl="http://exslt.org/common" in XSL at name space declarations. -
Mapping question - concat two nodes
hi all,
i need to map a node with many occurrencies to a node with only one ocurrency, and i need to concat all the values from the source node into the target node.
example:
<delivery> 1..unbounded --> <data> 0..1
<delivery> "this is "
<delivery> "an example"
result
<data> "this is an example"
does anybody know how can i solve this qestion?
thanks in advanced.
regards, FabianHi,
Go for UDF...
pass the source data as queue input to the UDF(i.e array)..in that udf loop over the source input and do concat inside the loop and pass the final result to the target element...
string target = "";
for(int i =0 ;i<input.length;i++)
target = target + input<i>;
if there are multiple contexts in this then need to handle the same

One to one mapping question -- can I just map a lookup field for queries?
I have a table with a state code. I'd like to have a "virtual lookup" on the java class to a region table. I.e., this java class "studies" has a state code. I can map a one-to-one to the descriptor class that has the ref table, but I'd like to have a property in the java class pre-mapped to the "region" field in this lookup so for querying i can just use:
ReadAllQuery q = new ReadAllQuery();
q.setReferenceClass(study.class);
q.setSelectionCriteria(new ExpressionBuilder().get("Region").equal(Region));
to get all the studies for a particular region.
am I going about this wrong? or do I have to get the reference table descriptor fromt he one to one map and do something different?well,on the way home last nite, I realized I'd had a complete brain fart. I've done this before. I just set up a 1-1 map between descriptors and then built the query like this:
q.setSelectionCriteria(new ExpressionBuilder().get("refFPO").get("FPO_NO").equal(FPO));
You can get the pointer to the "refFPO" which is the the descriptor mapped 1-1, then appended the column you wish to get.
I still went ahead and amended my class to include a read-only, non-toplink mapped attribute "FPO" which just gets the reference variable pointing to "refFPO.getFPO_NO();
I answered my own question just in case anyone wondered .... -
Complex mapping question (aggregate)

I am not a specialist in java so i would like to knowi if it's possible to do it with node standard functions ? if not, what is the best solution : XSLT, Java mapping, UDF ?
Thanks by advance,

Edited by: Jean-Philippe PAIN on Dec 16, 2008 12:14 PMhi,
with standard it would be pretty hard
but with a simple UDF (with 4 inputs) you can aggregate
and output it quite easily
try with a udf if you don't want to go for java mapping

I am trying to post the question in a different way. My previous post on the related subject can be found at Re: 1-1 mapping
Two entities, Parent and Child, where a Parent has a Child (privately owned) or zero Child.
In object model, Parent has an attribute child; Child does not have a parent attribute.
Two tables, Parent and Child, with constraint where a child record cannot exist without its parent record (i.e. Child table has a foreign key to the Parent table).
Class Parent and Child are mapped to table Parent and Child respectively.
How do we define the 1-1 mapping in the Mapping Workbench so that Parent and Child can be inserted into the tables in one unif of work?
Any comment or help would be greatly appreciated.
HaiweiYou can't do this as you described. You must have and map a relationship from child to parent in order to be able to map the 1-1 from parent to child (since your foreign key is in the child table).

Advanced Network Question - SSH tunneling through time capsule
Hi!
I have a small question. I just got a time capsule the other day and things are working great with it. At home, internet speeds are what they should be and everything is fine. I replaced it with a linksys, which I consistently got 6.5/1 up. After replacing it, I'm now getting 7.5 down/1mbps up, which is what I am subscribed to.
I used to ssh into my linux box and tunnel web traffic over SSH so when I'm on the road, other's can't sniff my traffic. Basically, I setup firefox to use a socks server, then ssh into home with a dynamic port mapping.
On the linksys (wrt54g), this worked great, and the speeds were acceptable (about 1mbps down/1mbps up). However, after switching the linksys with the time capsule, it seems like the speeds have slowed down tremendously. I'm now getting about 200k down and 1 mbps up when I ssh and tunnel web traffic through my home.
I know that this isn't anything people normally do, but it works great and prevents people from spying on my web traffic when I'm away from home. I was just wondering if anybody has any ideas on why it might be slower now that I replaced it with the time capsule.
