Reading Variables: Inconsistency in loading.

Hi,

I'm trying to make a restriction on 0CALMONTH using a variable that already exist in a new query. The problem happens when I try to see the available variables of 0CALMONTH. The system shows me the following message: "Inconsistency in loading. Please check use of deleted objects.".

It only happens with the 0CALMONTH characteristic.

Please, I would like to know if someone has already had this problem?

Tks.

Andre.
