Class 13 for rental property

I believe when a rental property has incurred a net loss, the CCA for this rental property can not be claimed. However, for tax cycle, the class 13 CCA is still claimed on the general S8. Is there a way to prevent this automatically? Or you will have to complete this manually?

Would it also be possible that if in the previous year the “Calculate CCA on buildings” is unchecked, it will be unchecked when rolled over?
I almost never claim CCA on buildings.

At the top of the S8Asset form there is a drop down box to associate a particular asset to the rental operation (Rental worksheet) Once you do this it should work properly
