Error messages regarding Catalog DTS task

Hi,

when executing the DTS package to import data into the data warehouse database even though the process seems to be successful I get the following errors in the Event Log:

Does anyone know what these errors mean and what could be wrong in the process?

Thanks!

It looks like the task encountered a data mapping problem. Was there a change in the catalog runtime schema recently?

What do you mean by catalog "runtime" schema? Is it the same as catalog schema? And what kind of change could cause such a problem? Not a change like adding a new property definition or associating a property to a product definition, right? We frequently do these kind of changes in our catalog and haven't noticed any problem so far.

I was referring the the catalog schema used to the runtime to distinguish it from the catalog schema that is defined in the DW. The Catalog DTS task transforms the data from the runtime schema to the DW schema. The error is noting that a string is being incorrectly mapped.

Has a new catalog property been marked for export to the DW?

No new catalog property has been marked for export, as far as I know. But I have restored the product catalog database from production environment in my development environment. Maybe this procedure has caused some "misunderstanding" regarding the fields defined in BizDesk that should be exported...

I'll check BizDesk definitions for the catalog properties to see if there's something different.

Thanks!
