Hi Saritha,

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

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.

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.

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.

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.

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

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

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

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

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

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

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.

Step 8: Assign files

Execute step ‘Assign Files’ and the system automatically defaults the filename to the source structure.

Step 9: Read data

In this step, LSMW reads the data 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.

Step 10: Display read data

This step is optional. If required, you can review the field contents for the rows of data read.

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

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

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.

***If you want example with screen shots provide me your Id I 'll mail it.

Regards,

Naresh

Hi,

I think this is helpful.

TRANSACTION CODE:::LSMW

LSMW Steps For Data Migration

How to develop a lsmw for data migration for va01 or xk01 transaction?

You can create lsmw for data migration as follows (using session method):

Example for xk01 (create vendor)

Initially there will be 20 steps but after processing 1 step it will reduced to 14 for session method.

1. TCode : LSMW.

2. Enter Project name, sub project name and object name.

Execute.

3. Maintain object attributes.

Execute

select Batch Input recording

goto->Recording overview

create

recording name.

enter transaction code.

start recording

do recording as per ur choice.

save + back.

enter recording name in lsmw screen.

save + back

Now there will be 14 steps.

2. MAINTAIN SOURCE STRUCTURES.

Here you have to enter the name of internal table.

display change

create

save + back

3. MAINTAIN SOURCE FIELDS.

display change

select structure

source_fields->copy fields.

a dialogue window will come .

select -> from data file

apply source fields

enter No. of fields

length of fields

attach file

save + back

4. MAINTAIN STRUCTURE RELATIONS

display change

save + back

5. MAINTAN FIELD MAPPING & CONVERSION RULE

display change

click on source field, select exact field from structue and enter

repeat these steps for all fields.

save+back

6. MAINTAIN FIXED VALUES, TRANSACTION, USER DEFINED

execute

save + back

7. SPECIFY FILES.

display change

click on legacy data
