    Hi All,

    Thanks for your replay.

    For recon a/c uploading we can upload directly by removing recon indicator in OAMk and after completion of the uploading we can reassign recon indicator in same T.Code OAMK.

    Correct me if i am wrong.

    Regards,

    Srinivas

    Hi

    Use the T.Code FB01 to upload the transactional data and for Assets use T.Code AS91. Transactional data is little bit tricky to upload from legasy system to SAP than Master data. Because some repeated fields will be for transactional data (ex: in double entry system a transaction has a minimu two line items and you will have some repeated items for these two line items. So in maintain fields fields the system will not allow repeated items.) So you have the edit the repeated items after recording process (after pressing default all button) and add a single digit number to the repeated fields at the end of that field name. (Ex: amounts field WEARS edit this repeated field as WEARS1). Like, you have to edit all repeated fields after recording process. Then it will trigger all the fields. The remaining process is same as master data upload.

    The full form of LSMW is Legacy System Migration Workbench. As the name specifies itu2019s a tool in SAP for migrating the legacy data to SAP system.LSMW is the transaction code used to start.

    Commonly used importing technology in LSMW are

    Direct Input method

    Batch Input Recording

    BAPI Method

    IDOC method

    In this tutorial we describes about the steps involved in creating an LSMW project for migrating the legacy data.

    In LSMW we are doing the things in a step by step procedure and the next step screen will be automatically displayed after very step. Here are the steps involved in LSMW.

    Step 1: Maintaining Object Attributes

    Here we are specifying about the project, subproject, object and importing technology (like batch input, IDOC etc.)

    Choose maintain object attribute from the LSMW steps screen

    Choose Change

    Specify the Object

    Specify the nature of data transfer that one time or periodic.

    Select the object type and import technique.

    Step 2: Maintaining the source structures

    Here we define the structure of source.

    Choose maintain the source structure from the LSMW steps screen

    Choose Change

    Point your mouse on Source Structures

    Choose Create Structure

    Enter the name and description for the structure

    Choose Continue

    Step 3: Maintaining Source Fields

    After the creation of structure in step 2, in this step we are going to define each field in that structure.

    Choose maintain source fields from the LSMW steps screen

    Choose Change

    Point your mouse on the Source Structure where we are going to add fields.

    Choose Create Field.

    Enter the field name, text, length and type

    Choose Continue

    Step 4: Maintaining Structure Relationship

    Here we specify the relationship between the SAP structures and the source structures created in step 2.

    Choose maintain structure relationship from the LSMW steps screen

    Choose Change

    Point your mouse on the SAP structure ID.

    Choose Relationship.

    Point your mouse on the corresponding source structure.

    Choose Continue

    Choose check for finding any errors in relationship.

    Step 5: Maintaining Field mapping and Conversion Rules

    The mapping between SAP structure fields and source structure fields, and conversion rule is specifying in this step. Instead of manual mapping, auto field mapping option is also available.

    Choose maintain field mapping and conversion rule from the LSMW steps screen

    Choose Change

    Choose extras -> auto field mapping

    Choose the appropriate options

    Step 6: Maintaining Fixed Values, Conversions and User-Defined Routines

    Specifying the conversion rules for processing data. Here we specify the fixed values etc.

    Choose maintain field mapping and conversion rule from the LSMW steps screen

    Point the mouse on the field where we want to add rule

    Choose insert rule

    The rules list will display. Select the rule.

    Set the indicator

    Choose Continue

    The normal available rules are

    Initial

    Constant

    Transfer (MOVE)

    Fixed Value (Reusable)

    Translation (reusable)

    Prefix

    Suffix

    Concatenation

    Left trim

    ABAP coding

    User-defined routine

    Step 7: Specifying files

    In this step we will specify the files used for the migration.

    Choose Specifying the files from the LSMW steps screen

    Enter file name, description and other settings

    Step 8: Assigning files

    Here we assign the specified files to the corresponding source structure.

    Choose Assign files from the LSMW steps screen

    Choose change

    Point the mouse on a structure

    Choose Assign file

    Select the corresponding file

    Press Continue

    Step 9: Importing Data

    In this step press execute to read the data from source.

    Step 10: Displaying Imported Data

    In this step choose continue to display the data that has been read.

    Step 11: Converting Data

    In this step choose execute to transfer the read to the file of converted data.

    Step 12: Display Converted Data

    In this step choose execute to display the converted data.

    Depending on the importing technology specifies in step 1. The next steps may have.

    Step 13: Create batch input session

    Step 14: Run batch Input Session.

    OR

    Step 13: Starting IDOC generation

    Step 14: Starting IDOC processing

    Step 15: Create an IDOC overview

    Step 16: Start IDOC post processing
