What are Interface/Conversion Programs in SAP?

Updated Jul 11, 2018

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.
