ORA-08006: specified row no longer exists " while compression

Hi All,

I am getting ORA-08006 error while compressing a cube.

This cube has active aggregates.

The messages are like below:

@5B@    Aggregation of InfoCube 100031 to request 2872   @35@

@5B@    statistic data written    @35@

@5B@    Zero elimination switched on    @35@

@5B@    Requirements check compelted: ok    @35@

@5B@    enqueue set: 100031    @35@

@5B@    compond index checked on table: /BIC/E100031    @35@

@5B@    enqueue released: 100031    @35@

@5C@    ORA-08006: specified row no longer exists    @35@

@5C@    ORA-08006: specified row no longer exists    @35@

@5B@    Collapse terminated: Data target CUBE01, from  to 2872    @35@

However, after repeating the step, the PC runs fine with no errors.

Let me know what can be done to remove this recurring error.

Thanks
