IR - Imported object - Import idoc error

Hello, I want to import Idoc metadata in Integration Repository but the following error occured :

             ***Ready for import***

Import started...

ORDERS.ORDERS05: 
  + com.sap.aii.ibrep.sbeans.upload.RemoteUploadException: The function module "DD_DOMA_GET" not released for 'remote' calls.

Import failed with 1 error

I've already done the IDX2 import with success.

The business system on which I get metadata is R3 46C

Any idea ?

Thanks a lot
