KB419732: ’ORA-01466 unable to read data -- object definition has changed’ error message appears when running a report in MicroStrategy Developer 10.x against Oracle

SYMPTOM:
In Strategy Developer 10.x, when users run a report against Oracle they see the following error message:
'ORA-01466 unable to read data -- object definition has changed. Error code -214721544.'
 
CAUSE:
This issue occurs because of a time-based read consistency error for a database object, such as a table or index.
 
Either of the following may have happened:

• The query was parsed and executed with a snapshot older than the time in which the object was changed.
• The creation time-stamp of the object is greater than the current system time. This happens, for example, when the system time is set to a time earlier than the creation time of the object.

 
ACTION:
To resolve this issue, the action depends on the cause of the issue.

• If the cause is an old snapshot, then commit or rollback the transaction and resume work.
• If the cause is the creation time-stamp in the future, ensure the system time is set correctly.

 
If the object creation time-stamp is still greater than the system time, then export the object's data, drop the object, recreate the object so it has a new creation time-stamp, import the object's data and resume work.
