Showing calculated attributes to the end user on a page will be too performance intensive when the data size grows larger. You should probably change this to stored value, so do the calc while someone changes the object or creates it.
When you use calculated attributes on a datagrid → all the objects will fire the calculated microflow which is not recommended.
Additionally filtering is not supported for calculated attributes see here
Thanks for the explanation – makes sense.
I will change the attributes to ‘stored’.
