LSMW- 14 STEPS
LSMW - Helpful hints for Support PM for transaction updates using recording option.
Here you have to first Define Project, Sub Project and Object. It is mainly for grouping the objects. One can have multiple subprojects and Object in a Project.
Execute the transaction and you will get navigated to the second screen: LSMW Work Bench. Here one can choose the required steps by pressing the ‘User Menu’ button.
These core tutorials will help you to learn the fundamentals of sap mm.

The following 14 steps are sufficient for Support person for the LSMW update.
Step1. Maintain Object Attributes
Define the method of upload. i.e. batch recording , direct update , BAPI etc. Go inside this step and choose the radio button for the options. This document explains only about the transaction recording method.
One can toggle between the Display or change option using the standard button. Select the object type and Import method as ‘Batch Input Recording’. Once you have selected this click on the overview button so that you can go to the recoding
Example of a recording
After recording default those fields that you want to update /use in batch update.
Step 2. Maintain Source Structures
Give any name, which can be easily identifying the input data structure. (It is equivalent to defining an internal table in a ABAP program). Can define multiple structures also (if required).
Step3. Maintain Source Fields
Define all those fields that you are giving in the input file here. The order should match the order of fields in the file. Otherwise it will get updated into the wrong fields. (Most of the errors might be in this step)
Step 4. Maintain Structure Relations
Define the source and destination structure relation ships.

Step5. Maintain Field Mapping and Conversion Rules.
You have to define the mapping rules.., eg. Customer = customer. Or if any default value has to be passed , or some fixed value is given like that ( company code can be a default value if processing for a particular company code.
After making all the mappings and initialization you can even do a syntax check to see your mappings are correct or not
Step6. Specify Files
You have to specify the input file location in this step.
Step7. Assign Files
Assign the physical file path to the structure
Step8. Read Data
Reading the file to the source structure
Step9. Display Read Data
This is very useful step where we can review the field values that got read.
Step10. Convert Data
Converting the source structure data to the destination by applying the conversion rules that have mentioned in step 4 and step 5.
Step 11. Display Converted Data
Also useful for checking the values converted.
Step12. Create Batch Input Session]
This will create a BI session in SM35.
Step 13. Run Batch Input Session
This step will call SM35 .One can run the session in SM35. You can run in foreground, Error mode or background. Preferably run in Foreground for testing some few records…once confirmed the update then run in back ground.
How to transport the LSMW project from Test to Production system;
The LSMW projects can be transported between systems via export /Import method.
You can export the entire project as a text file and that can be imported to another system.
In MSS no changes are allowed, so before importing to MSS , give the MSS file path in MST and then do an export .
