N:1 mapping question

Hello, can any1 please help me achieve the following mapping,
Input Msg Types:
Header (0..1)
   FieldH_A (0..1)
   FieldH_B (0..1)
LineItemType1 (0..n)
   FieldLN1_a (0..1)
   FieldLN1_b (0..1)
LineItemType2 (0..n)
   FieldLN2_a (0..1)
   FieldLN2_b (0..1)
Output Msg Type:
OutMsg (0.1)
   FieldOut_A (0..1)
   FieldOut_B (0..1)
   LineItems (0..n)
      FieldLN_out_a (0..1)
      FieldLN_out_b (0..1)
Mapping rules should be as following;
Header (0..1) -
> OutMsg (0.1)
   FieldH_A (0..1) -
>    FieldOut_A (0..1)
   FieldH_B (0..1) -

Hi,
Raj, i've tried to explain better by the following artwork :P
so i need to map 2 different type of segments from input type into 1 type of segments on output type.

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

A top difficulty mapping question

Hello
dose anyone can give solution for this mapping question?
soruce :
<header>header</header>
<item>
     <A>a1</A>
     <B>b1</B>
     <C>c1</C>
</item>
<item>

<item>
     <A>a3</A>
     <B>b3</B>
     <C>c3</C>
</item>
target:
<header>header</header>
<item>
     <A>a1,a2,a3 .....</A>
     <B>b1,b2,b3 .....</B>
     <C>c1,c2,c3 .....</C>
</item>
The numbers of item is not fixed,it is unbounded.
so the target line length is not fixed at design time
welcome any hits,
Thanks !!

Hi,
Use cache parameter as Context.
public void add_element(String[] a,ResultList result,Container container)
//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)

Many-to-many mapping question

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 ;)

Mapping question

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,
Peter

Hi,
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

Mapping - Questions

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,
Vivek

hi,
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.

ABAP Mapping Questions

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.

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 ....

1-1 mapping question

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.
Haiwei

You 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).

Port mapping question - I need clarification

I have posted a question about port mapping previously but - although I thought I understood - it is still not working for me. I was hoping there was a kind soul out there who could humor me and explain port mapping with AEBS 802.11n as if there where talking to a 5 year old.
Thanks for the help and it's ok to laugh.

{quote:}This address MUST be outside of the range of IP addresses that your 802.11n AirPort Extreme Base Station's (AEBS) DHCP service is providing.{quote}
This actually is incorrect.
The statement that the mapped internal address must be static is correct; otherwise the AEBS will not, if the Mac is assigned a different dynamic (DHCP) IP address by the AEBS some time in the future, be able to forward packets to the Mac. However it is very straightforward to have the Mac computer be assigned an address dynamically by the AEBS and to have the AEBS always assign the same IP address to the same Mac computer. Thereby giving the Mac a static address inside the DHCP range.
In the AirPort utility go to Internet | DHCP | DHCP Reservations. Click "+" then enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the Mac computer, give it an IP address, save it. Then that Mac computer will always receive that (static) IP address from the AEBS.
Why do this? Well by continuing to use DHCP (while having though a static IP address) you keep all the other benefits of DHCP such as automatically having the gateway address, the DNS server addresses given to the Mac. Otherwise you have to enter all this information manually on the computer if you put it outside the DHCP address range. This is very desirable, especially for most home users, as their DNS server entries are provided by their ASP and picked up by the AEBS. If the ASP changes DNS addresses the manually configured Mac machine will not know.
So in summary - for port forwarding it is NOT necessary for the Mac machine to be outside the DHCP range, in fact _it is desirable to keep it in the DHCP range_ *as long as* the Mac utilises DHCP reservation on the AEBS.
I have tested this and it works fine.

XI mapping question

Hello,
I have a situation that I need to run Z-BAPI function before starting mapping in XI. Let me explain scenario with more information.
1. I need to update a order in the SAP. The order may or may not exists in the SAP.
2. We have a Z-BAPI function that checks if Order exists in the SAP.
3. The mapping shall takes place upon sucessfully finding the Order in the SAP. Incase no Order found, mapping should not be done.
4. The sender sends multiple orders at same time and incase if an order was not in SAP, Mapping should not takes place and move on to next order.
Now my question is what/how exactly I need to do to avaoid mapping incase an Order has not found and move on to next order in the queue.
Please let me know.
Thank you,
Balaji

Balaji,
Just for understanding....
You are interested in generating outputs only for Order exist in R/3 system..right?
I mean do not want to generate XI output in case order do not exist but at the same time it will generate output for remaining orders which exist in the R/3 system..right?
If so...mean you are not interested whether it runs mapping or not..
In this case using graphical mapping you can check if order exist in R/3 system( In UDF you can call your ZBAPI to check ) and base on the output of your function module you can decide whether to generate header node or not...
Let me know if you need more details.

Mapping Question p3: .. etc.. namespace prefixes

Does anyone know why xi uses namespace prefixes like p3: p2: etc..? I am trying to map based on an rfc as the target and a message from a wsdl as the source. I can not test the map because it expects the test file ( from our partner ) to have all these P3:'s in it and it doesn't. Here is a snippet of what is happening at translation ....
<p3:Execute2 xmlns:p3="http://www.some/namespace/">
<p3:transaction-limit type="Amount"><p3:value>99999999999</p3:value></p3:transaction-limit><p3:transaction-limit type="Number"><p3:value> 9999</p3:value></p3:transaction-limit></p3:daily-transaction-limits><p3:single-transaction-limits></p3:single-transaction-limits><p3:monthly-transaction-limits></p3:monthly-transaction-limits></p3:authorization-control><p3:request-type>Activate</p3:request-type>
Message was edited by: Andrew Alpaugh

Hi Andrew,
the question is a little bit unclear to me. When I get you right, you have a WSDL that describes a message you get from a partner. You use this WSDL to define a Message Mapping. The Message Mapping does not work as expected. The fragment you have posted is probably what the Message Mapping seems to expect (according to the test panel). But the message you get from your partner looks different (it does not have all these prefixes).
I suppose that the schema contained in the WSDL (more precisely in the types-section) states that all elements have to be namespace-qualified (this could e.g. be done by having an elementFormDefault="qualified" in the schema). Thus, if the elements are unqualified in the message you get from your partner it simply means that the partner does not stick to the WSDL.
If this does not help you, I would have to see the WSDL and an example message that failed to work.
Note, however that there are different ways to express namespaces. If the document sent by your partner looks as follows:
<Execute2 xmlns="http://www.some/namespace/">
<transaction-limit type="Amount">...
it is logically equivalent to the one you posted, and the Message Mapping will treat them identical.

Mapping question using @OneToOne @PrimaryKeyJoinColumn

I am trying to create a simple web application to maintain a ContractAssignment table.
Created an EJB from this table with @Id of contractNumber.
public class ContractAssignment .....
@Id
@Column(name = "CONTRACT_NUMBER",
nullable = false,updatable=false)
private String contractNumber;
@OneToOne @PrimaryKeyJoinColumn
private Contract contractInfo;
I need contract info that exists in multiple tables so I created a view called Contract.
Created an EJB for this view with @Id of contractNumber.
public class Contract ......
@Id
@Column(name="CONTRACT_NUMBER", nullable = false,updatable=false)
private String contractNumber;
I will only be maintaining the ContractAssignment EJB.
The Contract EJB will NOT be maintained by this app.
It will only be used to obtain valid contract numbers that can be used in ContractAssignment maintenance.
It will also be used to display contract information when maintaining the ContractAssignment.
Is this the right way to map the relationship?
Another question. I've created a search page to look up ContractAssignments.
For some reason, the SQL generated is joining the table to itself.
Not sure if this is because of incorrect mapping (described above).
SQL that was generated:
SELECT t0.CONTRACT_NUMBER, t0.DESCRIPTION, t0.CONTRACT_START_DATE, t0.IMS_STATUS
FROM CONTRACT_ASSIGNMENT t0,
CONTRACT_ASSIGNMENT t1
WHERE (CONTRACT_NUMBER = ?)
     bind => [1234]
from the following OQL:
select o from ContractUserAssignment o where ocontractNumber like :contractNumber
What is causing the incorrect join?
Thank you for any help.

All - Thanks much.. Here is my requirement that is no solved by regular mapping
<Root>
<Recordset>
<Ordheader>
    <ord>
    <ord_type>
</Ordheader>
   <Ord_line>
     <ord>
     <Linnum>
   </Ord_line>
</Recordset>
<Recordset>
<Ordheader>
    <ord>
    <ord_type>
</Ordheader>
   <Ord_line>
     <ord>
     <Linnum>
   </Ord_line>
</Recordset>
<Root>
As you see above, each recordset has order transaction. One Root message can contain multiple of these. So, when I map to the IDOC, I want to filter out any ord_type <> XX.
If I use regular graphical map, it only looks at first recordset and accepts all or rejects all.
I need to use UDF. In the UDF, what comes in as input ? Resultset is output -correct ? Now how do I usse graphical mapping with UDF to generate the correct target info

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
Peter

hi 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().

EDI - IDOC mapping question

Dear Experts,
For transformations between EDI and basic IDOC types, are there any off-the shelf (ready to use) options? If yes what are they? If not, what is the easiest way of mapping in between these structures?
Our setup involves Seeburger's AS2 adapter.
Thanks

Hi Aamir,
Thank you for your response.
We are working in an environment where we do not have any control over the setup. So I have a few follow up questions, answers to which would help me immensely.
1. I saw that there are a"few" mappings available for which both the EDI and IDOC versions differ from what we need. So, is there anyway to get an actual listing of all supplied mappings?
2. In case you have worked for a similar scenario, is it possible for you to share a sample mapping spreadsheet ?
Thank you,

SAP Cloud for Customer : Code list mapping question

Hi All.
I have a basic question. When we do code list mapping for our own defined mapping group and have to choose Data Type name what should be used as Namespace. I usually see two entries but not sure of their purposes. What is the difference between the two ? Which one should be used when we are trying to map custom CRM/ERP OnPremise values with new ones i cloud.
Please see attached snapshot.
