Cause
the sum of PCTUSED and PCTFREE for a partition whose name (explicitly specified by the user) is displayed in this message exceeds 100. Note that if PCTUSED and/or PCTFREE values for this partition were not specified explicitly, default values for the partitioned table or index would be used. If, in turn, default PCTUSED and/or PCTFREE values for the partitioned table or index were not specified, system defaults would be used.
