This document applies to SAP versions ECC 6.0. For more information, visit the ABAP homepage.
Summary
This article contains the guidelines for using the SMT (Service mapping Tool) Mapping. Main purpose this is
data mapping in interfaces. Through SMT Mapping we can simply map fields in an input structure to output
structure. It will reduce the coding and enhance the performance of the code

SMT (Service Mapping Tool)
Introduction
SMT Mapping we can do through the transaction code SMT. Before doing the mapping we need to create a
package group. This created package group we want to specify while creating the mapping. In the creation of
mapping we need to specify each mapping as mapping steps. The SMT is a program that enables you to fill
target structures by using sets of source structures (in ABAP). It supports: simple mappings, mappings with
field transformations, complex transformations and field checks. Possible applications of the tool include:
preparation of data for further actions, conversions of Enterprise Service data to an SAP-internal format, and
vice versa. The SMT supports specific requirements for service implementations, such as extended XML
handling or field checks. The SMT executes standard mappings before extensions. Any checks that you
have activated for overwriting fields are never active for extensions.

SMT (Service Mapping Tool)
Select the menu item ‟ define package groups‟
Check the package group whether it is exists already
If does not exists, press new entries button and create a new package group
Assigning Packages
In the Tree Menu Select the package group and double click on packages

Using SMT Mapping in Code
Refer the below while writing SMT code in the program
Step 1: first it will initialize smt engine
Step2: Then it will map the source to target
DATA:
lo_smt_wcdvl_data
lx_smt_error
lo_smt_protocol
TYPE REF TO cl_smt_engine,
TYPE REF TO cx_smt_error,
TYPE REF TO cl_smt_protocol.
Initialize smt engine
TRY.
CREATE OBJECT lo_smt_wcdvl_data
EXPORTING

i_mapping_step

i_with_prefetch
= abap_false.
CATCH cx_smt_error INTO lx_smt_error.
lo_smt_protocol = lx_smt_error->a_protocol.
CALL METHOD lo_smt_protocol->get_messages_as_bapiret
IMPORTING
et_message = lt_message.
APPEND LINES OF lt_message TO et_return.
RAISE EXCEPTION TYPE cx_sapplco_standard_msg_fault.
ENDTRY.
Map data
