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
kumar

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.

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
Sud

<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/forums">https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/forums</a>
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

Service Pack needed for ABAP MApping ?

Hi everyone.
i'm trying to activate the ABAP MAPPING but it's no working.
I've done everything SAP documents say. Even i've followed all your posts but it doesn't work.
I wanto to know if ABAP MAPPING is available for Service Pack 9 (the one i have).
Thanks.

Hi
According to help.sap for ABAP Mapping
<i>"To reference the development objects of the ABAP Workbench from interface mappings, customers must assign the following value to the parameter com.sap.aii.repository.mapping.additionaltypes in the exchange profile:
<b>com.sap.aii.repository.mapping.additionaltypes=R3_ABAP|Abap-class;R3_XSLT|XSL (ABAP Engine)</b>"</i>
So go in Exchange Profile and chk whether this parameter has this value.
U can also go thru this blog to test ur mapping

Hope it helps.

User mapping when installing JAVA addin for ABAP

Hi,
I have installd SAP ABAP on a domain.
As the ABAP went fine and successfully gets installed.
When I am installing JAVA addon for ABAP it is throwing an error lke the users are not mapped.
So can any one guide me where actually I should map the SAP users in a domain.
Prashanth

Your question is very vague, please post the full error.
As this is a java add-in it should user ABAP as datasource so no user mapping should be required.
User mapping is used where java and backend system use different datasources and the naming conventions are different...
Theres not enough information here to give you an objective answer.

Hi Jyotsna,
Which mapping we need to use..
/people/udo.martens/blog/2006/08/23/comparing-performance-of-mapping-programs
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/xi/mapping%2btechniques
ABAP MAPPING...
You can implement the following mapping programs by using the ABAP Workbench:
     ABAP mappings [Seite 375] in ABAP objects
     XSLT mappings (ABAP Engine) [Seite 376]
Use
ABAP mappings are mapping programs in ABAP objects [Extern] that customers can implement using the ABAP Workbench.
Prerequisites
Note the prerequisites in the sections Purpose and Integration as well as the Restrictions in Mapping Development with the ABAP Workbench
Features
An ABAP mapping comprises an ABAP class that implements the interface IF_MAPPING in the package SAI_MAPPING. The interface has a method EXECUTE with the following signature:
Importing Parameter                                               Parameter Meaning
SOURCE(Type XSTRING)                                   Source XML document
PARAM(Type Ref To IF_MAPPING_PARAM)            Parameter object for read access to runtime constants (see below)
TRACE (Type Ref To IF_MAPPING_TRACE)     Trace object for writing messages in the mapping trace (see below)
Exporting Parameter                                                  Parameter     Meaning
RESULT (Type XSTRING)                                Target XML document
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) [Seite 376]) 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 [Seite 367], 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 (see above).

Kishore

Creating ABAP class in XI for ABAP mapping

DOM Programming in class for ABAP Mapping?

Hi All!!
I am struggling in transforming XML to be mapping target structures in using ABAP Mapping.
so i am on developing class with DOM.
i would like to know how many <person> derived from source xml, so what method should i use so that i can get that result. or does anyone idea how to work with multirecord to output XML?
data: incode1 type ref to if_ixml_node_collection,
incode2 type ref to if_ixml_node_collection,
get message content of tag <FirstName>
incode1 = idocument->get_elements_by_tag_name( 'FirstName' ).
incode2 = idocument->get_elements_by_tag_name( 'LastName' ).
<?xml version="1.0" encoding="UTF-8"?>
*Source XML
<ns:Personalinfo xmlns:ns="http://sap.com/test/ABAPMapping">
<person>
<FirstName>ABAP</FirstName>
<LastName>ITEM1</LastName>
</person>
<person>
<FirstName>ABAP</FirstName>
<LastName>ITEM2</LastName>
</person>
</ns:Personalinfo>
Message was edited by: Tony

Tony,
You need to use the method get_length. Try something like: -
*Get the list of child nodes
child_nodes = idocument->get_children( ).
*Get the number of children within child_nodes.
int = child_nodes->get_length( ).
Thanks

Debug ABAP code used for ABAP mapping

Hi Experts,
I have worked on Abap mapping. I have executed the code in SE24 to acheive desired mapping and the desired output is also generated.
attached below is a part of the code i have used:
method IF_MAPPING~EXECUTE.
* initialize iXML
TYPE-POOLS: ixml.
CLASS cl_ixml DEFINITION LOAD.
* create main factory
DATA: ixmlfactory TYPE REF TO if_ixml.
ixmlfactory = cl_ixml=>create( ).
* create stream factory
DATA: streamfactory TYPE REF TO if_ixml_stream_factory.
streamfactory = ixmlfactory->create_stream_factory( ).
* create input stream
DATA: istream TYPE REF TO if_ixml_istream.
istream = streamfactory->create_istream_xstring( source ).
* parse input document =================================================
* initialize input document
DATA: idocument TYPE REF TO if_ixml_document.
idocument = ixmlfactory->create_document( ).
* parse input document
DATA: iparser TYPE REF TO if_ixml_parser.
iparser = ixmlfactory->create_parser( stream_factory = streamfactory
istream = istream
document = idocument ).
iparser->parse( ).
I just want to debug and see if an input is provided how does each of these methods make a difference to it.
I tried to input some value in the SOURCE parameter on executing the code but it is not working fine.
Could you please suggest hiw i should go about so that i can see the exact way the input Xstring is affected by each of these methods in the debugger.
Help will be appreciated.
Many thanks,
Neha
Edited by: Neha Nagrani on Jul 7, 2008 11:46 AM

Hi Neha,
Write a Small Report as Folows:
1. Create your XMl payload of Type xSTRING.
2. Call the method EXECUTE
Place a Breakpoint on the method. and then keep debugging inside.
the SetParamter method is obviously called from inside.
This is the Simplesrt Solution.

Error the class for ABAP mapping doesnt exist

hi PI gurus,
i faced a probleme when i was trying to call a second Mapping which type is ABAp after another one which type is Message Mapping, why i m doing that because i was trying to folow the step by step of michal :

Getting busy icon in map when i use Custompointcallback for dvt maps

Hello Gurus,
I am trying to use custompointcallback function in mappointtheme for my project. Below is the code for the method i using in my bean.
public PointContent processPointInfo(DataContent dataContent) {
GeoRowObject obj= dataContent.getGeoRowObject();
String[] str =obj.getFormattedValues();
String pointHTML = str[0];
String selectHTML = "You are selected";
String hoverHTML = "Mouse over";
PointContent pContent = new PointContent(pointHTML, selectHTML, hoverHTML);
return pContent;
When i call the above method, i am getting a busy icon in my application. Can you please tell me what i am doing wrong?

OK, I see what's happening. When the driver was originally saved it was saved from a working directory instead of from the instr.lib. It's still OK. LabVIEW updated the links. Just re-save the VIs once they open.
I have seen that there are also a driver "Virtual NRT for Power Meter NRTZ43", but I have the version for WIN 95/NT. And I don't find a version to WIN XP. Can u help me to find the correct version for my pc?
That's an application that Rohde&Schwarz wrote. I think the latest version is here: http://www2.rohde-schwarz.com/file/NRT_ZV2_1.EXE.
vanny wrote: I have connected Power Meter to this port:
but I haven't istalled my Power Meter. I have only put in instr.lib the folder of driver taken by site of Rohde & Schwartz.
In the manual (if u want to help me really with heart read please) there is write that I must set the PORT COM, but when I have seen in Panel Control of Windows and after in System the Power Meter is unrilevated (NOT DETECTED). But with labview I have illogical miasurement.
If I find the program to see the power in and reflected maybe I can understant if labview function is correct.
I wait you... but now Are u sleep? Eheh, kisses...
If you connected the power meter to the computer it's installed. The power meter will not be detected because it's a serial connection. An instrument connected over the serial port cannot be automatically detected in MAX (Measurement & Automation Explorer) like a GPIB instrument can. In LabVIEW you have to tell it which serial port you connected it to.
In MAX you will see the COM ports:
In the LabVIEW driver you set the COM port this way:
COM 1 --> ASRL1::INSTR
COM 2 --> ASRL2::INSTR

Java Mapping, XSLT Mapping, ABAP Mapping

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.
cheers,
Sunee

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
