Not able to to see interfaces after doing export import of the Business sys

Hi Gurus,

I am exporting an business system associated with CRM system from Dev system of XI 3.0 to dev PI 7.1 system client 500. After taking the export from XI 3.0 , when I import the business system in PI7.1 and associate it with the corresponding Technical system I am unbale to see the interface associate with the Business system. Thus I am having a problem of creating the Receiver Determination, Interface Determination etc in the Integration Directory of the PI 7.1 system. Can anyone suggets how to get the interfaces associated with the Business system....

Thanks

Regards
