1. LSMW SIRISHA V

2. LSMW stands for  SAP Legacy System Migration Workbench. LSMW is used transfer data from one system to another system. The data transfer between the SAP to SAP (or) non SAP to SAP from sender system to receiver system The LSM Workbench provides a recording function that allows generating a “data migration object” to enable migration from any required transaction The main functions of the LSM Workbench are: Import data  (legacy data in spreadsheet tables and/or sequential files) Convert data  (from source format to target format) Import data  (into the database of the R/3 application)

3. Legacy data on pc Legacy data on application server Read data Convert data Structure Relation Field Mapping Conversion Rules Converted data R/3 Standard Batch input Processing

4. To start the LSMW workbench use transaction LSMW Project: specify the name of the data transfer project Subproject: one or more subprojects can be assigned to a project Object: Name of the LSMW object

5. Click Execute The next screen gives the  STEPS  in your LSMW data Migration Step 1- Maintain Object Attributes. Batch Input Recording : Here you can create a recording of your own and use it to upload/change data

6. Step 2 – Maintain Source Structures The source structures can be used to design the hierarchy of the files to be uploaded.

7. Step 3- Maintain Source Fields In this screen, the Fields which will be uploaded from the text file can be maintained here. The fields with identical names are taken as the Key

8. Step 4 – Maintain Structure Relationships

9. Step 5- Maintain Field Mapping and Conversion Rules

10. Step 6- Maintain Fixed Values, Translations and User-written Routines Step7- Specify Files

11. Step 8- Assign Files

12. Step 9- Read Data

13. Step 10- Display Read Data In this step, you can display all or a part of the read data in table form. Clicking on a line displays all information for this line in a clear way

14. Step 11- Convert Data

15. Step 12- Display converted Data Step 13- Create Batch Input Session

16. Step 14- Run Batch Input Session

17. MASS

18. SAP mass maintenance is a process of changing multiple master data entries at once. Mass maintenance of master records is required when there are a lot of existing master records and you need to change certain data fields in those records. When using  MASS  transaction, you will need to specify Object Types to determine which master data you want to touch with the maintenance process. Now, let’s go through a step-by-step example and carry on mass changes of CUSTOMER field for several CUSTOMER master records. We need to start the transaction  MASS  from the transaction bar

19. In the initial screen of  MASS  transaction, you need to enter Object Type. You can see a list of available object types by clicking on box besides this field. If you click this box, a list of object types will be displayed. In our example, we will use BUS1001 object type.

20. The SAP system will show the next screen where you should check the box besides General Material Data and click on Fields tab
