Hi Kiran,
- You can give default destination as XI_IDOC_DEFAULT_DESTINATION and point to one of the SAP system, if the system could not find the system in multi repository then default destination will use to get the metadata, i have pointed this destination to ERP system,
- Maintain multi repository like above but when the application com.sap.aii.adapter.idoc.ra starts multi repository will be recalculated.
Regards,
Praveen.
