Yet Another Great Step by Step LSMW Tutorial

In an SAP R/3 implementation the data from legacy system (non SAP R/3) needs to be transferred to the SAP system. Periodic data transfer between R/3 and other system (interfacing) is also required. Both of the above form a part of data migration. In SAP, known tools for data migration are:

  • BDC (Batch Data Communication)
  • LSMW (Legacy System Migration Workbench)

This document presents high level view of LSMW and to provides you information about how to use this functionality. Following are the headlines from this study material:

  • Difference between BDC & LSMW
  • What is LSMW ? Principles, Features and Pre-Requisities for LSMW
  • Import methods defined: IDOC’ s,BAPI’s, Standart/Direct Input, Batch Input
  • Step by step procedures for using conversion tool LSMW
  • Step by step procedures for Direct Input Method, Batch Input Method, BAPI in LSMW and so on..

Definition, Integration and Advantages of BAPI

The SAP Business Objects held in the Business Object Repository (BOR) encapsulate their data and processes. External access to the data and processes is only possible by means of specific methods – BAPIs (Business Application Program Interfaces). A BAPI is defined as a method of a SAP Business Object. For example, the functionality that is implemented with the SAP Business Object type “Material” includes a check for the material’s availability. Thus, the Business Object type “Material” offers a BAPI called “Material.CheckAvailability”.

BAPI Tutorial

Definition:
A Business Application Programming Interface (BAPI) is a precisely defined interface providing access to processes and data in business application systems such as R/3. BAPIs are defined as API methods of SAP Objects. These objects and their BAPIs are described and stored in the Business Object Repository (BOR).

Use:
BAPIs can be called within the R/3 System from external application systems and other programs. A BAPI call can either be made as an object oriented method call or as a remote function call (RFC). BAPIs are a global communication standard for business applications.
