RFC is remote enable function module --

LSMW is tool to update the date into SAP R/3 Transaction..

Reward points if it is helpful

Thanks

Hi Geetha,

RFC and LSMW are not interlinked in any way.

RFC is Remote Function Call. These are the remote connection enabled function module. They can be called remotely from other SAP system or any other system.

LSMW is SAP provided tool to upload the legacy data into SAP system.

RFC

Communication between applications of different systems in the SAP environment includes connections between SAP systems as well as between SAP systems and non-SAP systems. Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. The RFC calls a function to be executed in a remote system.

In all SAP systems, CALL FUNCTION represents an integral part of the ABAP language. This statement executes a function (a function module) in the same system.

REMOTE FUNCTION CALL (RFC) is an extension of CALL FUNCTION in a distributed environment. Existing function modules can be executed using an RFC from a remote system. This is done by adding a DESTINATION clause to the CALL FUNCTION statement:

Hi,

RFC mean Remote Function Call--> which mean thru RFC we can connevt to another external system (inorder to call a Function module or watever may be the purpose).

Lsmw --> is used to uplaod the data from legacy to R/3 thru any of the following methods:

batch input

direct input(absolete)

idoc

Bapi

Reward with points if helpful.

Revert back if any issues

Hai,

RFC :

RFC is a function module which can be called from a remote system.

RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.

RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.

RFCs manage the communication process, parameter transfer and error handling.

LSMW:

Legacy System Migration Workbench(LSMW) is a tool for Uploading the Data into SAP.

It uses the following Methods for uploading the Data.

a.Direct Input/Batch Input

b.BAPI

c.IDoc

Regards,

Padmam.

LSMW:

The LSM Workbench is an R/3-based tool that supports You when transferring data from non-SAP systems ("Legacy Systems") to R/3 once or periodically.

The tool supports conversion of data of the legacy system in a convenient way. The data can then be imported into the R/3 system via batch input, direct input, BAPIs or IDocs.

Furthermore, the LSM Workbench provides a recording function that allows to generate a "data migration object" in an entry or change transaction.

The main advantages of the LSM Workbench:

• Part of R/3 and thus independent of individual platforms

• A variety of technical possibilities of data conversion:

• Data consistency due to standard import techniques:

Batch input

Direct input

BAPIs (Business Application Programming Interfaces)

IDocs (Intermediate Documents)

The import technique to be used in an individual case depends on the business object.

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

• Clear interactive process guide

• Interface for data in spreadsheet format

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

• Charge-free for SAP customers and SAP partners
