Step-by-Step Guide for Using LSMW to Update Customer

Master Records

by Mitresh Kundalia,

SAP Practice Manager, Quality Systems & Software ()

Business Case:

As a part of reorganization and to better serve the customer needs, you are regrouping

many of the customers. In SAP terms, you are changing the Sales Office, Sales Group

and Customer Groups for specific Customer Master Records. Typically, you would

maintain customer records with transaction XD02 to update ‘Sales View’. You would

enter Customer Key (Customer No, Sales Organization, Distribution Channel, and

Division) and update relevant fields on Sales View screen.

This document contains Step-by-step instructions to use LSMW to update Customer

Master Records. It has two demonstration examples - one using Batch Recording and

another using standard SAP Object.

Note!

The screenprints in this article are from IDES Release 4.6. They may differ slightly

in other versions.

Demo Example 1

LSMW to Update Customer Master Records with Transaction Recording

Call Legacy System Migration Workbench by entering transaction code LSMW. Every

conversion task is grouped together as Project / Subproject / Object structure. Create a

Project

called

LSMW_DEMO

and a

Subproject

as

CUSTOMERS

and Object as

CUST_REC

as shown in

Figure 1.

Step-by- Step guide for using LSMW

The main screen of LSMW provides wizard-like step-by-step tasks, as shown in

Figure 2

.

To complete your data conversion, you need to execute these steps in sequence. Once a

step is executed, the cursor is automatically positioned to the next step.

Note that these steps may look different depending upon your

Personal menu

settings.

You could make step numbers visible by ‘Numbers on’ icon or hidden by ‘Numbers off’

icon. You can execute a step by double- clicking on the row. Toggle icon

‘Doubleclick=Display’ or ‘Doubleclick=Edit’, makes the step in ‘display’ mode or

‘change’ mode.

Step 1: Maintain Object attributes

In this example, you will be updating the customer master records with the help of

recording a transaction (XD02). Choose radio button

Batch Input Recording

and click

on the recording overview icon to record the R/3 transaction. Enter the

Recording

name

as

XD02_REC

, the description as

Customer Master Updates Recording

, and the

transaction code as

XD02

.

Figure 3

Object type ‘Transaction Recording’

The system calls the transaction code XD02 and prompts you to complete the

Change

Customer

transaction, as shown in Figure 4. Enter the key customer information (I

entered customer number 1000, sales organization 1000, distribution channel 01, and

division 00) and choose ‘Sales’ view within ‘Sales area data’. Make changes to these

three fields (I entered, sales office 1010, sales group 110, and customer group 01) and

save the transaction.

Once the transaction is completed, R/3 records the flow of screens and fields and saves

the information, as shown in

Figure 5

.

Field Names

Default Values

Transaction recording overview

Note that the fields are populated with default values. The values you entered when you

recorded the transaction are set by default.

Note that if you have more fields in the recording than needed, you can remove them by

clicking ‘Remove Screen field’ icon.

Observe that the transaction-recording process stores field names in a technical format.

By pressing the F1 key on individual screen fields and then pressing the F9 key, the

system displays technical names. You then can replace the technical names with

descriptive names. Double-click on the field

RF02D-KUNNR

and enter the name as

KUNNR

and the description as

Customer Account Number

and remove the default

value. (See

Figure 6

.)

Similarly, double-click on all other fields with default values and make appropriate

changes. Once you have made changes, the recording overview screen looks like what

you see in

.

Save your changes. When you go back to the initial screen, you will see that the initial

screen steps have changed. Since you want to import data via the BDC method, the

Direct Input

and

IDoc-

related steps are hidden, as they are not relevant.

Step 2. Maintain Source Structures

Give a name and a description to the source structure (

Figure 8

).

Figure 8

Source Structure

Step 3. Maintain Source Fields

In this step, you need to list what fields are present in the source structure. The easiest

way is to click on ‘Table Maintenance’ icon to enter Fieldname, Type and Length for

each field

as shown in

Figure 9

.

Figure 9

Source fields of source Structure

Note that your input file will have four fields as key fields and you need to update three

fields in the system.

Step 4: Maintain Structure Relations

Execute a step to ‘Maintain Structure Relations’. (See

Figure 10

.) Since, there is only

one Source and Target Structure, the relationship is defaulted automatically.

Step 5: Maintain field mapping and conversion rules

Field

RF02D-D0310

represents that you chose ‘Sales view’ for the customer Master

screen accordingly its value should be set to

X

. Keep your cursor on field RF02D-D0310

and click on

Constant

rule icon to choose the constant value of ‘

X

’.

If your source file already has the field value, you choose rule ‘Source Field’.

Keep cursor on field ‘KUNNR’ and click on ‘Assign Source field’ icon to choose source

field CUSTOMER from structure XD02S as shown in

Figure 11

.

Figure 11

Assign source fields

Similarly, assign ‘Source Field’ rules to the remaining fields.

Once all the fields are mapped, you should have an overview screen as shown in

Figure

12

.

Step 6: Maintain fixed values, translations, user-defined routines

You can also maintain re-usable translations and user- defined routines, which can be

used across conversion tasks. In this case, that step is not required.

Step 7: Specify files

In this step, we define how the layout of the input file is. The input file is a [Tab]

delimited with the first row as field names. It is present on my PC (local drive) as

C:. (See

Figure 13

.)

your local drive (C:) and name it .
