SELECT grants are provided directly (do I need more then select?) - I've just checked it. If schema TARGET has its own private link then all goes well, if not then while creating a mview the rdbms throws 00942. 00000 - "table or view does not exist". This error is when in the view in the MIDDLE schema there is no qualification (ie. there is from some_view@SRC and not some_user.some_view@SRC). If I add it then I 've got 04052. 00000 - "error occurred when looking up remote object %s%s%s%s%s" thus it seems that when I call the MIDDLE view from TARGET session in a query, it is done entirely on MIDDLE objects, but when I try to build a mview the definition is somthing like copied to the mview definition and then performed - then in a wrong context.
