equipment attributes problem is psa

Dear gurus,

problem is all about 0equipment_attr, i received errors in logs,

error arises from;

eq number

10000062 to 31.12.9999 start 09.06.2008

10000062 to 09.06.2008 start 30.05.2008.

error message:

The time interval ['20080609'/'20080609'] & (from/to) for the d

records 99 & and 57 & overlaps in characteristic 0EQUIPMENT &.

Whats wrong with that equipment, how can i solve that problem, ican change the data and upload to cube, but need to solve the problem first.

Thanks
