HI,

JAVA mapping

ABAP mapping

ABAP mappings run on ABAP Stack and are developed in the ABAP workbench of the Integration Server.

You normally do not need to use the ABAP mappings and is preferable for someone with ABAP programming background. I should say JAVA functions would suffice any complex scenarios.

refer step by step guides for ABAP Mapping

XSLT Mapping

XSLT stands for EXtensible Stylesheet Language Transformations. It is an XML based language for transforming XML documents into any other formats suitable for browser to display, on the basis of set of well-defined rules.

Steps required for developing XSLT Mapping

u2022 Create a source data type and a target data type

u2022 Create Message types for the source and target data types.

u2022 Create Message Interfaces includes Inbound Message interface and Outbound Message interface.

u2022 XSLT Mapping does not require creation of Message mapping, so donu2019t create any Message mapping.

u2022 Create an .XSL file which converts source data type into target data type.

u2022 Zip that .xsl file and import it into Integration Repository under Imported Archives.

u2022 In Interface Mapping choose mapping program as XSL and specify this zip program. (Through search help you will get XSL Mapping programs that you imported under Imported Archives, select your corresponding XSL Program)

u2022 Test this mapping program by navigating to Test tab.

By having look at above steps you can easily find out that this mapping is no where different from other mapping programs, here the challenging lies in creating an XSLT file. If you spend couple of minutes in studying XPATH tutorial you would be in ideal position to create an XSL Transformation (.xsl extension).

If you still find difficulties in generating XSL Transformation, then you can make use of a tool u201CAltova MapForceu201D which will create XSL file for you.

Steps for creating XSL file using this tool:

1. Open the Alto MapForce, import the source .xml and .xsd file in it

2. Similarly import the target .xml and .xsd in MapForce.

3. These two data files should match with source and target data types in Integration Repository.

4. Complete the graphical mapping using extensive list of XSLT functions available there.

5. Save the mapping file.

6. Click the XSLT tab. You will have the entire xslt logic there.

7. Copy that content and save it as .xsl file.

8. Zip above .xsl file and import the same into IR under Imported Archives.

Hope this clears your doubts

Hey,

ABAP MAPPING:

ABAP Mapping is used whenever you explicitly need to build your output XML structure . Its entirely depends on your call which approach you want to adopt i.e. JAVA mapping or ABAP mapping as in both the cases you need to explicitly build the output structure . ABAP Mapping however creates a DOM tree in the memory . Therefore it can be a performance issue whenever your source structure is complex

try this

JAVA MAPPING:

It is correct when you have the complex mapping , then go for Java mapping,

Or if you have more than 30 fields ..in your structure also go for Java mapping

see some helpful links

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)

Comparison of Mapping

********************

Graphical mapping -> We choose this mapping if the messages are small and no much complicated mappings are necessary...This is done by just dragging from sender to receiver message in the IR

Java Mapping-> This is done when the mapping is a bit complex...this mapping give a lot of flexibility .you can also access runtime constants like senderName or receiverName to implement a mapping that depends on message header

content.

XSLT Mapping->

Messages are in the form of XML documents. XSL Transformation (XSLT) is a member of the XML family of languages. It describes how an XML structure is transformed into another XML structure. We can even call external Java methods to convert XML messages

ABAP Mapping ->

This is based on ABAP OO classes
