XSLT Mapping on ABAP Engine

Hi All,
I am trying to implement an XSLT mapping on the ABAP Engine. I went to the Transformation Workbench(SE80).I have created 4 levels of packages (Structure->Main->then 2 more levels) and included Package Interface SAI_TOOLS in 'Use Accesses' tab.
I have also set com.sap.aii.repository.mapping.additionaltypes=R3_ABAP|Abap-class;R3_XSLT|XSL (ABAP Engine)
in the Exchange Profile.
Now I want to create the tranformation (ST or XSLT) so that I can see it in the Repository.
At which package level(1st to 4th), should I right-click and go to 'Create->More->Transformations' so that I can see this XSLT Mapping program in the repository?
I have followed all the links from help.sap.com but I am unable to get the desired result, i.e. see my Mapping in the Repository when I choose Mapping Program of type 'XSL->ABAP Engine', from the drop-down box in Interface Mapping.
Kindly help.
Regards,
Puloma.

Hi Naveen,
I did as you told, i.e. keyed in the name of the ABAP Transformation program (mapping) name.I have not written any namespace for the Mapping program in the Interface Mapping Design, just the Program name.
When I execute my mapping from se80, it works perfectly.
I created this Transformation program at the topmost level (i.e. Structure package level).
But when I execute my scenario, I get the following runtime error in sxmb_moni:
Error in mapping program zpc_transfom2 (type R3_XSLT, kernel error ID UNCAUGHT_EXCEPTION).
What is wrong? Did I create the transformation program at the wrong level?
Regards,
Puloma.

Raising Exceptions in XSLT mapping.?

Hi,
When there is an mapping exception, in UDF, i raise an exception...
Similar is the case with Java & ABAP mappings.
Now, How do i raise mapping exceptions in XSLT mapping (Java & ABAP)..?
--DJ

You could use Java enhancement, but instead of just adding info to the trace, you could raise a real exception, using an ErrorHandler object. Ive successfully worked with the one below (not with XSLTs, tho, but I dont see why it shouldnt work.

Hi,
There is no hard and fast rule for using the mapping techniques.
Graphical Mapping is used for simple mapping cases. When, the logic for your mapping is simple and straight forward and it does not involve mult hiearchical mapping requirement. and context handling.
Java and XSLT mapping are used when graphical mapping cannot help you.
When the choice is between Java And XSLT, XSLT is simpler than java mapping and easier. But, it has its drawbacks. XSLT can lead to a bad perfrormance if the Source XML is huge.
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.
For further info on each of the mapping, refer to these links,

Am not sure about XSLT , but , yes graphical mapping is converted into java classes internally and these classes use SAX parsing as well.

Hello,
Please see the code below.
This is how u call

Hi
All mapping related links
There is no hard and fast rule for using the mapping techniques.
Graphical Mapping is used for simple mapping cases. When, the logic for your mapping is simple and straight forward and it does not involve any complex logic.
Java and XSLT mapping are used when graphical mapping cannot help you and you have multilevel hierarchy structure data.
When the choice is between Java and XSLT, XSLT is simpler than java mapping and easier. But, it has its drawbacks. One among them being that you cannot use Java APIs and Classes in it. There might be cases in your mapping when you will have to perform something like a properties file look up or a DB lookup, such scenarios are not possible in XSLT and so, when you want to use some specific Java API's you will have to go for 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 exactly easy to develop either.
To know more about each of them please go thru the following links. And if you ask me your which is better, it depends basically on the scenario you implementing and the complexity involved. Anyways please go thru the following links:

Raise error in an external-function of XSLT-mapping (ABAP)

Hi,
we implemented a xslt-mapping (ABAP) in PI with external-functions.
It's a great feature and works fine.
Now, we have to implement an error handling:
The external-functions are reading data from an abap table. We have to stop the mapping (if a value in the table is missing).
We wanna show an error inside the PI-Monitoring (red flag) with a valid error text.
How can I raise an error inside an external-function?
regards
Wolfgang Hummel

Hi Michal,
thanks a lot for your answer.
Can I set dynamic configuration inside an external funktion of an ABAP-XSLT?
I added the CX_MAPPING_FAULT-Exception to my external-function method and raised an exception inside my external-funktion ... and I got an "UNCAUGHT_EXCEPTION" inside my mapping - bad

Hi Experts,
Could any one explain what is the main features of the following Mapping. How to pick the mapping?
Java Mapping - When to use and what is the advantage.
ABAP Mapping - When to use and what is the advantage.
XSLT Mapping - When to use and what is the advantage.
Graphical Mapping - When to use and what is the advantage.

There are 4 types of mapping in XI
1. Graphical Mapping
2. XSLT Mapping
3. JAVA Mapping
4. ABAP Mapping
When to use Message mapping
1 When the logic for your mapping is simple and straight forward, you can use
Advantages of message mapping
1)Easy to use.
2) has GUI drag and drop.
3) used for simple mapping cases
4) it does not involve any complex logic
Disadvantages of message mapping
1)has limitation in terms of complex hierarchy
When to use Java mapping
1) Java mapping are used when graphical mapping cannot help you.
Advantages of Java Mapping
1)you can use Java APIs and Classes in it.
2) file look up or a DB lookup is possible
3) DOM is easier to use with lots of classes to help you create nodes and elements.
Disadvantages of Java mapping
1)SAX parser is not easy to develop
2)DOM parser is intensive
3) Java knowledge is required
4) bit complexer
XSLT Mapping - When to use
1)When the required output is other than XML like Text, Html or XHTML (html displayed as XML )
2)When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
3)When data is to be filtered based on certain fields (considering File as source)
4)When data is to be sorted based on certain field (considering File as source)
5)When data is to be grouped based on certain field (considering File as source)
Advantages of using XSLT mapping
1)XSLT program itself defines its own target structure.
2)XSLT programs can be imported into SAP XI. Message mapping step can be avoided. One can directly go for interface mapping once message interfaces are created and mapping is imported.
3)XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
4)File content conversion at receiver side can be avoided in case of text or html output.
5)Multiple occurrences of node within tree (source XML) can be handled easily.
6)XSLT can be used in combination with graphical mapping.
7)Multi-mapping is also possible using xslt.
8)XSLT can be used with ABAP and JAVA Extensions
Disadvantages of using XSLT mapping
1)Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
2)Interface mapping testing does not show proper error description. So errors in XSLT programs are difficult to trace in XI but can be easily identified outside XI using browser.
3)XSLT mapping requires more memory than mapping classes generated in Java.
4)XSLT program become lengthier as source structure fields grows in numbers.
5)XSLT program sometimes become complex to meet desired functionality.
6)Some XSL functions are dependent on version of browser.
Advantages of Abap Mapping
1) A person comfortable with OOABAP can go for ABAP mapping instead.
Disadvantages of Abap Mapping
1) Abap knowledge is required
2) bit compexer

XSLT mapping throws error in XI, but not in XMLSPY

Hi everybody,
I got a really complex XSLT mapping. It works fine in XMLSPY.
But when I execute the mapping in XI, I get the following error:
Error during XSLT Transformation: Could not load stylesheet.com.sap.engine.lib.xml.util.NestedException: Operator or ')' expected.
I asume there is a special character that XI cannot execute.
has anybody an idea of finding this character?
Thanks, regards Mario

Hi Mario
Check your input data, and also try to see test in Interface mapping test tab,
you will get an idea about the input is correct or not

Graphical Multi Mapping and then XSLT Mapping

Hi I have to do message Split. I'm doing this message split. Then I have use XSL Mapping where I'm basically sending the whole Source message into Target Node. Basically Graphical mapping splits one Source file into 2 target files and XSL Mapping should move these individual files to 2 target messages. How Can I refer the Individual messages in the Mapping ?.
Since Actual message split takes place in Adapter Engine does XSLT Mapping acts on a Single message out of Graphical Mapping ( in my case Graphical mapping produces 2 messages ) or It acts on both messages as no actaul split didn't took place yet in the Mapping runtime.
No Guess work please ..let me know if you actually did it.Appreciate all your help.

Message splits (1:n mappings) can be executed without BPMs. It will finally occur, as you said, at the Adapter Engine layer.
When you deal with multimappings with graphical mapping, XI will automatically create two new tags surrounding your root tag(s) (tag in case you have multiple occurrence of 1 interface; tags in case your target messages are from different interfaces).
But when creating multimappings with XSLT, ABAP or Java, you'll have to handle these two surrounding tags manually. So, in your xslt, your input will be like:
> <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
> <ns0:Message1>
> <ns1:Your_Message1 xmlns:ns1="http://your.namespace1">...</ns1:Your_Message1>
> </ns0:Message1>
> <ns0:Message2>
> <ns2:Your_Message2 xmlns:ns1="http://your.namespace2">...</ns2:Your_Message2>
> </ns0:Message2>
> ...
> </ns0:Messages>
(in case your target message is just 1 interface with multiple occurrence, you'll have only <Message1> tag with multiple occurence).
So, the secret here is that you'll have to handle the <Messages> and <MessageX> tags in your xslt code.
Regards,
Henrique.
