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



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.

Figure 1 Conversion Task with Project, Subproject
and Object

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.



Figure 2 LSMW Wizard – initial screen


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.



Figure 4 Transaction recording for Transaction
Code ‘XD02’


Once the transaction is completed, R/3 records the flow of
screens and fields and saves the information, as shown in
Figure 5.




Figure 5 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.)



Figure 6 Field attributes


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 Figure 7.


Figure 7 Transaction Recording Overview – with
screen field attributes


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.


Figure 10 Structure Relation


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.

























Figure 12 Field mapping and Conversion rules overview


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:\XD02.txt. (See Figure 13.)











Figure 13 File attributes



Create an Excel file (Figure 14) with your data and save it
as a Tab-delimited text file on your local drive (C:\) and
name it XD02.txt.


Figure 14 Source data in Excel file (saved as Tab
delimited file)



Step 8: Assign files
Execute step ‘Assign Files’ (Figure 15) and the system
automatically defaults the filename to the source structure.


Figure 15 Assign file to Source Structure



Step 9: Read data
In this step, LSMW reads the data (Figure 16) from the
source file (from your PC’s local drive). You have the
option to read only selected rows and convert data values
to Internal format.


Figure 16 Read Data


Step 10: Display read data
This step (Figure 17) is optional. If required, you can
review the field contents for the rows of data read.

Figure 17 Display Read Data


Step 11: Convert data
This is the step that actually converts the source data (in
source format) to a target format. Based on the conversion
rules defined, source fields are mapped to target fields.


Step 12: Display Converted data
Again this is an optional step to view how the source data
is converted to internal SAP format (Figure 18).


Figure 18 Display Converted Data


Step 13: Create batch input session
Once the source data is converted in an internal format,
you can create a batch session to process updates (Figure
19).


Figure 19 Create Batch Input Session


Step 14: Run Batch Input Session
You can execute the BDC session by Run Batch input session.
Executing a batch input session is a standard SM35
transaction for managing BDC sessions. Once you have
successfully executed the batch input session, the customer
master records are updated in the system. You can confirm
this by viewing the customer master records (XD03).


Note! Browsing thru these 14 steps, you may get a feeling
that this is a very lengthy and time-consuming activity.
However, for the purposes of demonstration, I have made it
detailed. Although it looks lengthy, actually it takes
hardly few hours from start-to-finish! After playing around
with few simple LSMW scripts, you will find it so easy to
change and create more complex ones.





Demo Example 2
LSMW to Update Customer Master Records with Standard Object

As an alternative to using ‘Transaction Recording’, you
could also use a standard SAP object to update Customer
Master Records. Business Object ‘0050’ is already pre-
defined in the system with standard Batch Input Interface
Program ‘RFBIDE00’.

Create an Object CUST_OBJ within Project as LSMW_DEMO and
Subproject as CUSTOMERS as shown in Figure 20.


Figure 20 LSMW Object with Standard SAP Object

Note! For the Demo example 2, I will list only those steps
that are different from the first demo example.


Step 1: Maintain Object attributes
You will be updating the customer master records with the
help of Standard Batch Input; therefore, choose radio-
button Standard Batch/Direct Input as shown in Figure 21.
Enter Object ‘0050’ for Customer Master records and default
method ‘0000’ and click on Save.


Figure 21 Standard Batch/Direct Input Object Attributes



Step 4: Maintain Structure Relations
Sales view of Customer Master is stored in table KNVV.
Accordingly, you need to update structure BKNVV. However,
in addition, the Standard Object ‘0050’ also requires
updates to BGR00, BKN00 and BKNA1 structures. (If you do
not maintain Structure relations for mandatory entries, you
might get a message such as ‘Target structure BKNA1 needs a
relation to a source structure’.)

Even though you don’t want to update any fields in these
structures, you need to create a relationship with source
structures. In all, you need to create relationship for
four target structures.

Create relationship between source structures XD02S with
these target structures with icon ‘Create Relationship’ .


Keep Cursor on these four target structures and click on
icon ‘Create Relation’ and structure relations are
maintained as shown in Figure 22.



Figure 22 Structure Relation


Step 5: Maintain field mapping and conversion rules

-- Keep your cursor on ‘TCODE’ field and click on ‘Insert
Rule’ icon

Figure 23 LSMW Conversion Rules


Choose radio button ‘Constant’ (Figure 23) to enter
value ‘XD02’ transaction code.

-- Keep your cursor on field ‘KUNNR’ and click on ‘Assign
source field’ icon

Choose source field ‘Customer’ from source
structure ‘XD02S’. (See Figure 24.)


Figure 24 Assign Source fields

-- Similarly, choose source fields for Sales Organization,
Distribution Channel, and Division. (See Figure 25.)


Figure 25 Field Mapping and Conversion Rules


-- Scroll down to structure BKNVV fields and assign source
fields to three fields Sales Office, Sales Group, and
Customer Group (Figure 26).


Figure 26 Field Mapping and Conversion Rules

Save and go back to main screen.


Step 12: Display Converted data
When you convert data, LSMW automatically converts into the
appropriate structure layouts, as required by Standard
program (RFBIDE00). (See Figure 27).


Figure 27 Converted data into multiple structures


Note that if you had only one record in source file, the
converted file has four records.

Earlier, creating this input file, so that the standard
interface program can read it, was a big nightmare, the
primary reason being that it could have multiple record
layouts. Even for a simple conversion with one input
record, you would have to create this complex file with
many record layouts. The advantage of LSMW is that it
prepares these multi-layout files automatically.


Step 13: Create batch input session
Once source data is converted in internal format, you can
create a BDC session to process the updates (Figures 28 and
29).


Figure 28 Create BDC Session


Figure 29 BDC Session ‘CUST_OBJ’ created







Summary
Once BDC session is processed successfully, SAP updates the
customer master records with relevant changes. Review these
specific customers (transaction code XD03) and confirm that
the changes are correctly reflected in the master records.
