method for transfer of data. Total of 26 processing steps are available in LSMW, In case of data

transfer using Batch Input only 14 steps are required.

These are 14 steps are,

1 Maintain Object Attributes

2 Maintain Source Structures

3 Maintain Source Fields

4 Maintain Structure Relations

5 Maintain Field Mapping and Conversion Rules

6 Maintain Fixed Values, Translations, User-Defined Routines

7 Specify Files

8 Assign Files

9 Read Data

10 Display Read Data

11 Convert Data
