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.

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.

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.

Here is the difference

Hi,

When transferring data into the SAP system, we can refer to two types of transfers:

Conversions - This type of transfer refers to a one-time transfer from a legacy system to the SAP system. In this case, the “legacy” system is the old system that is being replaced by the SAP system.

For example, the old system being replaced has data for 2,000 vendors that must be transferred to the SAP system.

Interfaces - This type of transfer refers to an ongoing transfer from a complimentary system to the SAP system. In this case, the “complimentary” system is a system that will run along side the SAP system.

For example, customer orders may be taken in another system. For the SAP system to reflect accurate information, these orders must be transferred to the SAP system every night.
