Hi,

Conversion programs are used to load the data into SAP in required formats...They are usually one time run programs...They can be used to fetch the data from SAP or external systems or XLS or TXT files and then also update/load data into SAP...

Interface programs are also used to load data into SAP from the EXternal systems only...There exits connection from the external/legacy system(directly or through a middle ware-EAI,webmethod) ..They are NOT single run prorgam, data can be sent to system on daily/weekly or adhoc basis...

CONVERSION : Legacy System To Flat File.

INTERFACE : Flat File to SAP System.

When you transfer legacy data into the R/3 System, you need to ensure that it is in the SAP format. There are several ways of doing this:

1. Converting the data in the legacy system has the advantage that the user is familiar with the programming language that it uses.

2.Converting the data in the R/3 System using ABAP has the advantage of automatic type conversion. You can use the structure definitions of the ABAP Dictionary directly.

3.Converting the data with Excel. You can use this method for simple and complex conversions for flat structures.

4.You use interfaces defined by SAP for the standard transfer. The legacy data must be delivered in a suitable format to supply these interfaces. The interface descriptions are defined in the R/3 System and the transfer method is developed and formulated according to these descriptions.
