In Business scenario, it is required to upload the data into R/3 and process the data in the IDOC formonly. The data can be migrated to R/3 SAP system using IDOC Generation Method in LSMW. The data tobe uploaded can be regarding material, vendor, customer etc. IDOC is the container, which stores thedata in structured format and is used to communicate between R/3 systems. IDOC structureincludes Status Record for storing status information of IDOC dispatch, Data Record for storing data intosegments and its corresponding fields and Control Record has receiver and source system details etc.

This document contains Step-by-Step instructions to use LSMW to generate and process IDOC from thedata file available. In first part user-defined IDOC structure is created and required ALE settings are done.In the Second part, this IDOC structure is used in the LSMW IDOC.

Part One: To create IDOC structure

Step One: Run transaction WE31.Create Segment with name ‘ZEMP_SEG’.

Step Two: Input the fields for the segment structure, which would be required in LSMW for mappingpurpose.

Step Three: Now, Go to Edit -> Set Release, so that you can use this segment in the R/3 system further.



Step Four: Run transaction ‘we30’ and enter IDOC structure name we want to create.

Here, IDOC structure name is ‘ZEMP_IDC’.

Step Five:

(A) Add segment created earlier to this IDOC type ‘ZEMP_IDC’.



The maximum and minimum repetitions can be from 000000000000 to 99999999999.

Choose any number rang as per requirement.

Now, Go back to earlier page and Click Edit-> Set Release.

(B)Create new Message type in transaction ‘WE81’.

(C) Attach message type and IDOC type with the help of transaction ‘WE82’.

Step Six: Go to transaction ‘SALE’. Click as marked in red color.



Now add two logical system names for sender and receiver ex. IDC64 and IDC87.

Step Seven: Now assign clients to the logical systems created.

Select the client of your current system as per decision to make that system sender or receiver.



After clicking on to Goto->Details , you come to following screen. Input receiver system ‘IDC87’ to client800.

Here in our LSMW using IDOC method, no need to assign client to sender as we are doing InboundIDOC Processing (i.e. Receiver side).

Step Eight: Run transaction ‘WE21’ to create File port. Give directory name as the location of your file tobe read. Give dummy name for ‘Outbound file’



field.Step Nine: Run ‘SM59’ transaction to create RFC connection. Please make sure here connection type is‘T’ for TCP/IP

.

Step Ten: Run transaction ‘WE20’ to create partner profile for partner of receiver system (IDC87) i.e.sender system (IDC64).



Step Eleven: Create process code using ‘WE42’.

After saving this data, you go screen as below to attach function module to the process code. Theprocess code is the representation of the function module for inbound idoc processing.



Step Twelve: Now you can use this process code in the inbound parameters of the partner’s profile.

Part Two:

Following are the steps to be performed on LSMW side.

Step One:

Enter the project, sub-project and Object name for our scenario.



Step Two:

Click the first radio button ‘Maintain Object Attributes’ , execute and enter the message name and IDOCname into the screen as follows.

Step Three:

Click radio button ‘Maintain Source Structures’ and execute to create new source structure as follows.

Step Four:

Click radio button ‘Maintain Source Fields’ and execute to enter the fields in the source structure. Herethese fields are same as the fields in segment of the IDOC created earlier.



Step Five:

Click radio button ‘Maintain Structure Relations’ and execute to create relationship between source andtarget structure. Here target structure is Message type ‘ZEMP_MSG’.

Step Six:

Click radio button ‘Maintain Field Mapping and Conversion Rules’ and execute to create field mappingand a conversion rules between source structure and target structure.



Step Seven:

Click radio button ‘Maintain Fixed Values, Translations, User-Defined Routines’ and execute to assignfixed values to any field, to call user defined routines etc. These activities are not required in ourscenario.

Step Eight:

Click radio button ‘Specify Files’ and execute to assign file on the local workstation to the LSMW to read.The file has contents as shown below.

And now we specify the location of file here.



Step Nine:

Click radio button ‘Specify Files’ and execute to specify file to source structure as follows.

Step Ten:

Click radio button ‘Read Data’ and execute to read file from local workstation as per path specified.



Step Eleven:

Click radio button ‘Display Read Data’ and execute to display data just read.

Step Twelve:

Click radio button ‘Convert Data’ and execute to create a file with extension ‘.conv ’.

Step Thirteen:

Click radio button ‘Display Converted Data’ and execute to display the converted data.

Step Fourteen:



Click radio button ‘Start IDoc Generation’ and execute to generate the IDOC from the data provided andstructure mapping done earlier in this document. For this purpose, we cam use the converted file in steptwelve. After successful generation of IDOC, below shown message is displayed.

Step Fifteen:

Click radio button ‘Start IDoc Processing’ and execute to process the IDOC by inputting necessaryselection parameters.

Step Sixteen:

Click radio button ‘Create IDoc Overview’ and execute to show status and details of IDOC generated.This screen is similar to ‘WE02’ or ‘WE05’ transaction.



Here , as you can see , the status of IDOC is OK (Green color Bubble) and hence confirms successfulprocessing of IDOC.

Step Seventeen:

Click radio button ‘Start IDoc Follow -Up’ and execute to reprocess the IDOC if not posted or generatedproperly initially.

LSMW for Functional Consultants in

simple step-by-step waycreated by Ravi Sankar Venna on Sep 10, 2013 10:40 AM, last modified by Ravi Sankar Venna on Sep 10, 20131:53 PMVersion 1inShare

Legacy System Migration Workbench (LSMW) is handy tool for data uploads. In most of the big projects there is a separate

development / data migration team is available. However, at times, it would be responsibility of the functional consultant to loadthe data such as vendor master, customer master and asset master etc. It would be real handy for a functional consultant to knowLSMW (at least recording method) and it would help them to successfully complete the task. Hope this document would helpmany of our functional consultants, as I am seeing number of questions around LSMW. The simple rule is: Follow this document

and practice is for number of times possible, then you will become master.

Go to Transaction Code "LSMW" and follow the following steps:
