No one has recommended using an array so I'll suggest it.

I think you should create a subclass of combobox, add a custom property maValues[1]. Populate it in a custom method using a select:

select codigo, nome ;
from lote ;
into array this.maValues ;
order by 1

You can now step through the array and add \ to the front of the items that are not available for the current record. Issue a this.Requery() so the cbo will adjust itself based on the disabled items.
