When do we go for ABAP mapping and Java mapping

Hi friends,
At present I am working on graphical mapping in XI ,can you guys give me with an example or scenario when do we use ABAP mapping , Java mapping or XSLT mapping.
Thanks in advance

I have standard XSLT mapping programs available for my scenarios, so use XSLT mapping. Similarly with Java mapping, For most scenarios, message mapping does the job too well. Abap mapping similarly is used to leverge existing ABAP base. If message mapping becomes confusing and hard to follow with too many functions, I go for Java mapping (just my way). I havent used ABAP mapping thus far.
Discussing ABAP mapping
ABAP mapping is developed in ABAP work bench. ABAP mapping needs to be transported to integration server and XI does not support this transport and have to do with ABAP transports.
Customers who can develop mapping program on SAP web AS and can transport them there can use ABAP mapping
*ABAP mapping programs cannot access the value table
*Since ABAP mappings are executed on ABAP stack SAP does not provide any ABAP mapping programs
*ABAP mapping programs must exists with one single version in IS, unlike JAva and XSLT mapping that can have multiple versions of mapping program

ABAP Mapping and Java Mapping

Hello
Folks
     I have business requirement as below.
   X is a FMCG (Fast moving consumer Good) company. Need to take the financial transaction from customers per day 1 Million.
   When X company takes an electronic cash (Credit card). It need to communicate with X1 (Bank with legacy system).
My question:
Ideally what kind of mapping makes my Integration process an error free. Say less monitoring work. Less support.
   Basically I am looking for a RUGGED mapping process.
Thanks in advance for your answer and co-operation
Regards
Ashok Babu

Hi Babu,
<b>Ideally what kind of mapping makes my Integration process an error free. Say less monitoring work. Less support.</b>
Thats depends upon ur requirement.Best is to use Graphical mapping as it is easy to use and not that much complex compare to other mappings.But some in some complex scenario..JAVA/XSLT maaping is useful....
Check here the mapping performance...

When we wil go for abap mapping ??

Hi,
As we know there are graphical, XSLT, JAVA mappings are there apart from ABAP mapping. I have gone through below weblog.
/people/udo.martens/blog/2006/08/23/comparing-performance-of-mapping-programs
and also help.
http://help.sap.com/saphelp_nw04/helpdata/en/12/05731a10264057badc32d3d3957015/frameset.htm
None of them says ABAP mapping is either faster or stable as compared to other mappings. Even though it is the case, still when we will go for abap mapping ??
Is it like that it is totally depend on the available resources in hand ??
thanks

About your statement.
If you consider the field mapping (or UDF) runtime, then you are correct. But if you consider the whole mapping runtime, you also have to "load" the full message in message mapping, obviously. What happens is that it is transparent to the developer, since loading and parsing is done by standard. But message mapping also deals with loading and parsing the whole message (and it is done with Java underneath). Then I don't think message mapping will have a significantly better/worse performance, when compared with Java mappings (performing normal xml processing methods).
As for XSLT, the performance problems happens because you have a XSLT processor running over Java VM. Then, if you have heavy load on it, the mapping runtime will consume the resources necessary to run the xslt processor (which is, by itself, very resource consuming) and also to treat that heavy input.

Message Mapping ... ABAP ,XSLT and JAVA

HI Friends
I have a general question ... but it will confuse me a lot ....
my question is we have four types of message mappings
1) GUI ( and UDFs)
2) ABAP
3)XSLT
4) JAVA
when we have plenty of options in GUI (and User defined functions also) to define sender 2 receiver message mapping
then what is need of JAVA,ABAP and XSLT Message Mapping and when we use these message mappings( exactly in which situation) and difference b/w them
Thanks in Advance
Mahesh

Green = recommended
Yellow = Acceptable
Red = not recommended
In my experience.
XSLT mapping: is confotable to convert to another format different to xml(when we do not have a complex logic)
Java Mapping: is to implement complex logics(but the maintainbilityis not good...you need a external tool)
ABAP mapping: I think is the best option when the you have the skills on that technology but take account that is not portable neither good for usability.

ABAP and Java mapping

Wanted to confirm my understaing for ABAP and JAVA mapping.
Am I correct in my assumption that these mapping techniques can be used only if input and ouput is in XML format ?
So if XI is receiving a flat comma separated text/non-XML file or an IDOC for that matter and output is NOT in XML format, say again flat text file or IDOC, I cannot use above two techniques?
All the docs I have read suggest that 'Execute' method is called when XML file/data is received, paresed using DOM/SAX/JAXB (for Java mapping) or IXML lib (for ABAP mapping) and then create a output XML file.
-Thanks in advance

Hi Bob,
Here you have a code sample for deescaping. I have have written this code a couple of time ago. The incoming file can be any text format. It might be XML, but not necessarily.
The main method is not reqired, but good for testing.

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.
A few example cases in which an XSLT mapping can be used:-
When the required output is other than XML like Text, Html or XHTML (html displayed as XML)
When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
When data is to be filtered based on certain fields (considering File as source)
When data is to be sorted based on certain field (considering File as source)
When data is to be grouped based on certain field (considering File as source)\
Advantages of using XSLT mapping
XSLT program itself defines its own target structure.
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.
XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
File content conversion at receiver side can be avoided in case of text or html output.
Multiple occurrences of node within tree (source XML) can be handled easily.
XSLT can be used in combination with graphical mapping.
Multi-mapping is also possible using xslt.
XSLT can be used with ABAP and JAVA Extensions.
Disadvantages of using XSLT mapping
Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
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.
XSLT mapping requires more memory than mapping classes generated in Java.
XSLT program become lengthier as source structure fields grows in numbers.
XSLT program sometimes become complex to meet desired functionality.
Some XSL functions are dependent on version of browser.
Different types of Mappings
MAPPING SUPPORTED BY XI
Message Mapping -> Graphical Design and testing environment. Default Provided By XI. Queue based modelling allow handling or large documents. Extensible via user defined functions
XSLT Mapping - > Based on openstandard, Portable across application platform, Extensible using user defined functions kewl but disadvantage is Memory overload while handling large documents.
SAX -> Simple Api For XML. -> Allows you to parse through a XML document. Doesn't consume any memory. But the message can be parsed only once from top to bottom. It Has evolved by contributions made by group of ppl itz a open architecture.
DOM -> Document Object Model -> Itz designed by W3C. Consumes Memory as the message will be loaded. Allows parsing of document in both way top down and bottom up.
Send me your email id.Shall send you very good docs for both ABAP Mapping and message mapping.

Creating t.code for ABAP query and Transport it TO Production and run it .

Hi Friends
Thanks for ur reply ,
The requirement is that i want to create tcode for abap query and that query can be regenearted ,
in case of regeneration programe name i got answer programame name will be change, i created and modified query but i saw the same programe name ,,, may be it changed when it is trasnported if so then what ??
and also pls give me solution for asiging tcode for query which is going to be regenerated.
thanks and regards
farukh

Dear Farukh,
As we know,
Query is created in Production server and a corresponding program is generated by System.
What we have to do is just to assign the program to the desired transaction code in Development server and transport it.
If you have any doubts please let me know.
Kindly assign points if you find this info usefull.

Hi farukh,
1. If any query is re-generatred,
   then some MANUAL INTERVENTION
   is absolutely required.
2. Hence, what we prefer is this :
   1. Generate first query.
   2. Copy the code to a Z Program
   3. Attach tcode to THIS z program.
   4. Transport
3. Now,
whener the query is generated again,
   AGAIN COPY THE CODE
TO OUR Z PROGRAM (2ND STEP ABOVE)
                    (which has already been created)
AND TRANSPORT JUST THIS Z PROGRAM.
REST WILL TAKE CARE OF ITSELF.
4. In such cases,
ONLY COPY-PASTE IS REQUIRED.
(and it takes not more than 15 SECONDS)
