Application Development and Automation Discussions
Join the discussions or start your own on all things application development, including tools and APIs, programming models, and keeping your skills sharp.
Interfacing is connecting two or more different entities. In our case, it is connecting one or more systems with SAP. Now extending our previous example, you are replacing some legacy applications but there are some applications that you don't want to replace yet. You need to somehow pass data back and forth between SAP and these remaining systems. Data may be going one way or the other way or both ways. You will still need to do some data transformations/translations etc to make the data understandable to the receiving system. This will continue as long as you want to keep the systems running alongside SAP.
In short, conversions are written to load data into SAP onetime. These are typically file based.
Interfaces are written to exchange/update/send/receive data between SAP and other systems on an ongoing basis. These can be in many forms, file based, idoc based, real time(business connector, XI etc are useful in this), xml, and the list goes on.
There are two main interface used in SAP i.e EDI and IDoc. File interface also used in SAP.
When SAP system need to connect to external system then mostly interface has been used. EDI/IDoc are also used in SAP for distributed system for data exchange
