Usually CONVERSIONS programs are one time objects that will load the data into SAP system from the legacy system. this is usually done when SAP is being implemented for the first time or some legacy is being taken out of production and that functionality is being implemented in SAP.

INTERFACE programs are the ones that run on a regular basis and transform the data between two systems.

Conversions programs are BDC,BAPI and LSMW programs in which you upload all the related tables from the flat files.Those are one time programs.

Interface programs are those programs in which you fetch the data from the application server and process on theose data.These are helpful when you have to run any program in the backgroup when the presentation server is not working.

hi,

conversion program is your migration- or mapping- program to convert data in the format of the SAP-Interface

example:

-(customer)conversion program for vendors ZFKMIGR01 creates a file in the format of interface RFBIKR00

with the foll. structures

BGR00

BLFA1

BLFB1

BLFBK

CONVERSION programs are the ones which have one time usage, usually when a legacy system is being replaced by a system like SAP, then the data has to be mapped from the legacy system to SAP system. Here the data to be converted is given on a flat file & is uploaded to SAP tables mostly using LSMW only.

INTERFACE programs are the ones which are run at regular intervals, say weekly, monthly or even daily. Here the legacy system continues to co-exist along with SAP system, the legacy system might be useful for certain functionalities but the data might have to run thru SAP transactions for complex data maintenance at regular intervals.
