Steps for ABAP Mapping

Question

Hello,
     Can any one explain how to do ABAP mapping?and necessary trancsaction codes for this?
Ex: I am sending PO to reciever system.
And if posibel screen shots....plz
Thank you

Hi Jyotsna,
Which mapping we need to use..

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).
