SAP LSMW Concept

CONCEPT OF SAP LSMW

LSMW read documents and convert the contents to the target structure and the corresponding fields.
Then the data from the target structure create a SAP format of the document, this document can be used to transmit data.
SAP did not provide any standards conversion.

Steps:
- Read file (local or server, and we need to accept pre-defined data source structure).

- Save the contents of the documents as LSMW documents.

- Define the relationship between the structures and fields distribution .
(as defined in the source and target structure mapping).

- Define source fields and the value of the target fields conversion rule
(LSMW file how to change the definition of target structure)

The above structure and the conversion rule defined are executable in ABAP procedures and generating SAP format documents in the transfer process or LSMW in implementation.

LSMW support of the transfer methods:
- Standard transfer process (batch input, call transaction, direct input).
- IDocs
- BAPI
- Recording SHDB and generate batch input.

STEPS :
1. Go to LSMW
Maintain object attribution

2. Maintaining the original format
- Maintain source Structure
- Maintain source fields

3. Maintaining the original format and objectives of the mapping relationship between format
4. Maintain structure relations.
5. Maintain field mapping and conversion rules.
6. Maintain fixed values, translations, user-defined routines

Achieve the original data -> objective data format
7. Specify files
8. Assign files
9. Read data
10. Display read data
11. Convert data
12. Display converted data

Upload the target format data to SAP
13. Create batch input session
14. Run batch input session
