hi,
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:
1) Maintain attributes – choose the import method.
2)Maintain source structure/s with or without hierarchical relations. (Header, Detail)
3) 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
4) Maintain relationship between source and target structures.
5) 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.
6) Maintain Fixed values, translations, user defined routines – Here reusable rules can be processed like assigning fixed values, translation definition etc.
6) 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)
7) Assign Files – to defined source structures
8) Read data – Can process all the data or part of data by specifying from / to transaction numbers.
9) Display read data – To verify the input data being read
10) Convert Data – Data conversion happens here, if data conversion program is not up to date, it gets regenerated automatically.
11) 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
