LSMW:Upload Master Data Using Batch Input Recording Part 1

Introduction

The Legacy System Migration Workbench (LSMW) is a instrument to transmit data from legacy systems into an R/3 System. LSMW supports a step-by-step process; if one step is executed and saved then next step automatically follows. Apart from formation of project/ subproject/ object and recording, there are 14 basic steps included in LSMW. This article explains clearly about each and every step.

Example, I am showing how to upload Personnel Data for an employee i.e. Infotype 0002 .

Creating Project/ Subproject and Object:

Go to LSMW

Give the name of the Project, Subproject and Object as desired

/wp-content/uploads/2013/11/12_322732.png

Save and Back.

Step 2: Maintain Source Structures

Source structures are helpful in building hierarchical relationships. While uploading the data system always checks highest level structure first before going for subordinate structure.

Select source structure and create

/wp-content/uploads/2013/11/13_322743.png

First click on Change button and then click on create button.

/wp-content/uploads/2013/11/17_322754.png

/wp-content/uploads/2013/11/18_322755.png

Save and back.

Step 4: Maintain Structure Relations

Here we check whether structure relations between legacy and R/3 established or not.

In this step there is no need to change, just save and come back.

/wp-content/uploads/2013/11/19_322760.png

/wp-content/uploads/2013/11/20_322762.png

Save and Back.

In menu bar, go to ExtrasàAuto Field Mapping

/wp-content/uploads/2013/11/21_322766.png

After Execute go to Extra and then Auto Field Mapping.

/wp-content/uploads/2013/11/22_322767.png

/wp-content/uploads/2013/11/23_322768.png

Now accept proposal for all the fields which need to upload

Step 6: Maintain Fixed Values, Translations, User-Defined Routines

No need to maintain this step, unless and until if there exist any user defined routines, which helpful for reusable.

Step 7: Specify Files

In this step, you specify the location of the legacy file.

Note: Generally we receive legacy file in excel format, so save this file as Text

Now, double click on ‘Legacy Data – On the PC (Front End)

      Dear Jazib Tariq,

      Appreciated your efforts for making this useful document.

      Did you observe that LSMW did not delimit infotypes while uploading mass data? 😕

      If so, is there a method to make LSMW to delimit infotypes while uploading data for infotype changes?
