Loading PAS Measures not displaying

Dear Friends

Our PAS connection is successful in Context. Reports are displaying correctly retrieving PAS Data but when we are trying to map KPI i.e KPI Mapping , We are able to get PAS Model and could select but when trying to assign KPI to PAS measure getting Loading PAS Measures message and hanging up for long time and nothing error displaying.

What might be the reason ? Pl. advise
