WARN in Tomcat

Hi,

I'm getting the next Warn in the Tomcat web server log:

2010-03-04 07:45:50, 093 [main] WARN appserver.system: Object is not valid: ODPM-00055: The update table for Series name 'xxx' does not exist in the table 'Mdp_Matrix'/'Databse' , therefore no updates will be allowed on this series.

If someone else had the same problem I would appreciate his/her guidance.

Thanks in advance

Alin
