Integration Repository is a design time tool where we can design and develop different objects involved in XI Integration. This helps us create integration scenarios, message types, data types, interfaces and mapping objects and designing integration processes. These objects are organized under the software component versions. These SWC versions hence need to be imported from SLD before we can begin IR development.

In the previous article, we discussed the scenario and SLD settings required for the same. Here we will understand the IR part.

Go to XI Start Page (Transaction SXMB_IFR) and choose Integration Repository.

• Go to menu path Tools -> Transfer from System Landscape Directory -> Import Software Component Versions…
• Select your SWC and click ‘Import’
• The newly created SWC should now appear in the left frame. Expand the SWC, and double-click on the version
• On the Definition tab, select the Interface Import option as ‘Import of RFC and IDoc Interfaces from SAP Systems Permitted’
• Specify the System name and Client of the SAP system
• Add a namespace to the SWC to hold the repository objects
  • Namespaces can be defined in two ways:
    • URI format – http://abc.com/xi/scenarios
    • URN format – urn:abc-com:xi:scenarios

Import IDoc Interface from SAP System

• Expand the SWC and right-click on Imported Objects
• Choose to Import RFCs and IDocs
• Provide Logon credentials
• Choose the IDoc ZRZSO_MT.ZRZORDER, and continue
• Click ‘Finish’ to import the IDoc
