LSMW: Legacy System Migration Workbench

As we all know LSMW is very helpful and easy when it comes to upload heavy data into SAP system in

less time. Its a tool used to upload master data in SAP

Lets create a LSMW to upload condition type PR00, to upload new price for large set of materials.

Process:

Go to transaction LSMW and to will take you to below screen

SAP has provided user to segregate there LSMWs in a proper manner by divided it into 3 parts

Projects, sub projects and objects.

Click on the highlighted button to create a new LSMW a pop up will appear as shown below asking for

project name and description -

Project: Is the highest node in this hierarchy, in simple terms you can say category.



Fill in the appropriate project name and description of your LSMW and press ok. Again a pop up appears

asking for more details as shown below-

Sub project: It is 2nd node in the hierarchy; in simple terms you can say its a sub category

Fill in the appropriate Sub project name and description of your LSMW and press ok. Pop up demands

for more details as shown below-

Object: Object can be list of entities falls under the sub category.

Fill in appropriate object name and description and press ok.



Example:

After you fill in all details press the highlighted execute button or press F8, this will take you to below

screen.

Object

Sub Project

Project Eatables

Fruits

Fruit salad Fruit juice

Vegetables

Vegetable soup



This is the overview screen of LSMW.

Step1: Maintain object attribute

Here in this step we decide which process we used to input out legacy data into SAP system, SAP has

provided some of the process as shown below-

Standard Batch/Direct Input

Batch input recording

Business object method (BAPI)

IDOC (Intermediate document)



We will be using the Batch input recording method which I feel is bit simple when compare to other

process.

Click on the highlighted radio button of batch input record and then click on overview button which

is highlighted as well in the right side of above screen; it will take you to below screen-



Now click on create button highlighted in above screen to create a new recording, system will ask

you name the recording and describe it as shown below-

As soon as you name the recording and describe it system will ask for which transaction you want to do

recording.

Recording: As the name goes recording means recording step by step process how you key data in that

particular transaction, system uses this recorded example as skeleton to feed those thousands of entries

which you hold in sheet.



System takes you to VK11 (condition record maintenance screen) fill in data and complete one record as

shown below-



Click on save after you completes the transaction then system will take you to below screen



Click on the highlighted entry of the recording a pop up will appear as shown



Name the field as KSCHL in name column and then describe it as condition type in next name field, and

keep PR00 as default value if all of the records you want to feed in is on PR00 only otherwise make it

blank.

In this example I have all records for PR00 only so I will keep it as default only, as shown below-

In the same way click on second field and repeat the process again as shown below

As I dont want sales organization to be default I removed it from default value which was recorded by

system.

Repeat the same process for rest fields in the list and it always better to keep name of field as same

highlighted in above screen (standard) this will help in future step 5 when we try to map these fields.

This is how screen looks after you complete the process



1. Name of the fields

2. Default values

3. Options like default all, default, reset, delete field, add field repeat recording for quick access.

This complete the first step and as soon as you save changes system takes you to below screen for next

step, cursor goes to next step automatically as shown below



Step 2: Maintain source structure

Source structure is all about structure of you data file, its like a group name, system ask you to key the

name and description of structure, give some sensible name as shown below-

Press ok and this is how our structure looks like



Step 3: Maintain source field

Source fields: Its a set of fields names which we have in our source data file and details about them

Click on execute or press F8 system will take you to below screen.

Click on highlighted button of table content and system will take you to below screen where you can

feed in all source fields.



Fill all the fields in this table with their technical name, data type, field length and description as shown

above.

And it should be in the same order as you have positioned in the source data file with correct process as

per transaction.

Input file: Source data file



Its always betted to keep source data file in text format with tab delimited as shown above.

The above screen shows that the recently created source structure contains the recently create source

fields, both highlighted source structure and fields.

Step 4: maintain structure relation

This is the step where you relate your source structure which contains all source fields to the recording

which we created in first step, its just an assignment.

System automatically relates the recent created source structure with the recording which we have

created in first step,



Just click on change button and then save the transaction.

Step 5: Maintain field mapping and conversion rule

Field mapping:

This is the critical and most important step in LSMW; it is used to map the fields of recording (Step1)

with the source structure fields (step 4&5).



System shows all the fields which we have recorded in first step as shown above.



Then click on auto field mapping which hides under extras tab in menu bar to automatically map the

recording field with source structure fields. The below pop up appears-

Just make sure highlighted radio button is opted then system will map the same field name from

recording with same field name in source structure field name.



You can see that under target field, name of field is KSCHL from recording name REC8 (step 1) and under

source filed, name is the field is also KSCHL of source structure PR00_SOURCE_STRUCTURE (step 4)



Click on the accept proposal and continue doing same for rest all fields.

When it comes to dates and values system smartly ask for the format of date as shown below

System gives this message after auto mapping completion.



This is how screen looks after mapping gets completed.

Step 6: fixed values, translation and user define routine.

This is used to give fix value to some filed after mapping and to validate the date by using user define

routine. We will skip this step as this is optional and of no use for our LSMW.



Step 7: specify file

Specify file: It is the step where we show and specify where we store our source data file in our

directory.

Place the cursor on the PC first line and click on create button a pop will appear asking for

directory path



1. File path and file name.

2. Type of delimiter source data file contains (its tabulator in our case).

3. Whether file contain headings (field name) at the starting of file.



Step 8: Assign file

Here we just assign our source data file to the source structure which we have created in step 4.



Step 9: Read data

This will read all the records from the source data file, system shows that what will be the date and

value format as shown below-

After successful execution system display how many records has been traced from the source data file.



Step 10: Display read data

This is an optional step which shows the traced record from the source data file.



Double click on one record and system shows the record and its value traced while reading the source

data file.



1. File path where system stores the traced data from source date file, file path ends with read.

2. Source structure which has been assigned to source data file.

3. Field name of source fields of source structure.

4. Value extracted again field names from the source data file.

Step 11: Convert data

System converts the list of records traced from source data file into its own transactional format of VK11

in this step.



Click on the execution button or press F8 to proceed further



System shows number of records which have been converted.

Step 12: Display converted data



This is an optional step which shows the converted records from the source data file.

Click on any record it will show the converted data according to transaction VK11 as shown below



1. Path where system stores the converted data and file path ends with CONV.

2. Recording name which has been used as skeleton to convert the data from source data file.

3. Field names based on recording.

4. Values converted against the field names from source data file.



Step 13: Create batch input session

In this step we will create batch session which can be run in next step to run the heavy source data file.

Highlighted is the session name which system gives automatically.



An information pop up appears saying these many records has been created in this batch folder.

Step 13: Run batch input session

In this step we will run the batch input session which we had set in last step.



Select the latest session based on session name and user id and click on highlighted process button

A pop up appears as shown below-

Process/foreground: It runs the file in foreground, this is recommended when you run sample file to see

how system creates entry through batch input recording.

Background: System runs the file in background, this is recommended when you run huge file to avoid

manual work of pressing entry every single time.



Extended log: By enabling this system give detail analysis or log about both successful and unsuccessful

transactions.

This is how analysis screen looks like-

Go to VK13 (display mode of condition record) transaction and check random entries to confirm created

entries are accurate and correct.

This is the last step involved LSMW creation.
