Hi Rohit,

I recommend you to use Migration Workbench (transaction LSMW). It provides you lots of object types for Direct Input import method.

Reward points if useful.

hi,

a brief explanation about LSMW and STEPS to do it,

LSMW – Step by Step Guide: Legacy System Migration Workbench is an R/3 Based tool for data transfer from legacy to R/3 for one time or periodic transfer.

Basic technique is Import data from Spreadsheet / Sequential file, convert from source format to target format and import into R/3 database. LSMW not part of standard R/3, if we need this product email lsm@sap.com

Advantages of LSMW:

• Most of the functions are within R/3, hence platform independence.

• Quality and data consistency due to standard import techniques.

• Data mapping and conversion rules are reusable across projects.

• A variety of technical possibilities of data conversion.

• Generation of the conversion program on the basis of defined rules

• Interface for data in spreadsheet format.

• Creation of data migration objects on the basis of recorded transactions.

• Charge-free for SAP customers and partners.

Working With LSMW:

Use TCODE LSMW

Objects of LSMW:

•Project – ID with max of 10 char to Name the data transfer project.

• Subproject – Used as further structuring attribute.

• Object – ID with max of 10 Characters, to name the Business object .

• Project can have multiple sub projects and subprojects can have multiple objects.

• Project documentation displays any documentation maintained for individual pop ups and processing steps

User Guide: Clicking on Enter leads to interactive user guide which displays the Project name, sub project name and object to be created.

Object type and import techniques:

• Standard Batch / Direct input.

• Batch Input Recording

o If no standard programs available

o To reduce number of target fields.

o Only for fixed screen sequence.

• BAPI

• IDOC

o Settings and preparations needed for each project

Preparations for IDOC inbound processing:

• Choose settings -> IDOC inbound processing in LSMW

• Set up File port for file transfer, create port using WE21.

• Additionally set up RFC port for submitting data packages directly to function module IDoc_Inbound_Asynchronous, without creating a file during data conversion.

• Setup partner type (SAP recommended ‘US’) using WE44.

• Maintain partner number using WE20.

• Activate IDOC inbound processing.

• Verify workflow customizing.

Steps in creating LSMW Project:

• Maintain attributes – choose the import method.

• Maintain source structure/s with or without hierarchical relations. (Header, Detail)

• Maintain source fields for the source structures. Possible field types – C,N,X, date, amount and packed filed with decimal places.

• Fields can be maintained individually or in table form or copy from other sources using upload from a text file

• Maintain relationship between source and target structures.

• Maintain Field mapping and conversion rules

• For each Target field the following information is displayed:

o Field description

o Assigned source fields (if any)

o Rule type (fixed value, translation etc.)

o Coding.

o Some fields are preset by the system & are marked with Default setting.

• Maintain Fixed values, translations, user defined routines – Here reusable rules can be processed like assigning fixed values, translation definition etc.

• Specify Files

o Legacy data location on PC / application server

o File for read data ( extension .lsm.read)

o File for converted data (extension .lsm.conv)

• Assign Files – to defined source structures

• Read data – Can process all the data or part of data by specifying from / to transaction numbers.

• Display read data – To verify the input data being read

• Convert Data – Data conversion happens here, if data conversion program is not up to date, it gets regenerated automatically.

• Display converted data – To verify the converted data

Import Data – Based on the object type selected

• Standard Batch input or Recording

o Generate Batch input session

o Run Batch input session

• Standard Direct input session

o Direct input program or direct input transaction is called

BAPI / IDOC Technique:

• IDOC creation

o Information packages from the converted data are stored on R/3 Database.

o system assigns a number to every IDOC.

o The file of converted data is deleted.

• IDOC processing

o IDOCS created are posted to the corresponding application program.

o Application program checks data and posts in the application database.

Finally Transport LSMW Projects:

• R/3 Transport system

o Extras ->Create change request

o Change request can be exported/imported using CTS

• Export Project

o Select / Deselect part / entire project & export to another R/3 system

• Import Project

o Exported mapping / rules can be imported through PC file

o Existing Project data gets overwritten

o Prevent overwriting by using

‘Import under different name

’

• Presetting for Inbound IDOC processing not transportable.

hope it helps u,

hi rohit sharma,

for direct input, run the program "RMDATIND" in abap editor.

hope this will help u.

REWARDS POINTS IF USEFULL
