Hi all,
1.) How is Inside out Approach Different From Outside in approach in XI?
2.) Do we have proxies coming into picture in Inside out approach.?
3.) SAP uses only Outside in ..! why not Inside out approach..?
Hi,
just have a look at this quote given by Michal in other thread..
You can use the following approaches when developing interfaces:
· Outside-In: You can develop new, platform-independent message interfaces by using the Integration Builder. Message interfaces are based on the WSDL standard Web Services Description Language), an XML schema for describing network services. Using this description, you can generate platform-specific proxies in Java or ABAP that you can then use to implement the actual message exchange.
· Inside-Out: You can connect interfaces from SAP and non-SAP systems to SAP Exchange Infrastructure by using adapters. The Integration Builder can import interface descriptions in XML format for BAPI, RFC, and IDoc interfaces from SAP systems Release 4.0 or higher.
from:
http://help.sap.com/saphelp_nw04/helpdata/en/ba/d4c23b95c8466ce10000000a114084/content.htm
basically it's all about where you start developing
your interfaces either in XI (and later one in the
system - by proxies ) or in system first and then you try to match
to this interface in XI (by importing IDOCs, RFC, external definitions etc.)
