I am a bit confused about the relation between Parent and child content type.
Now I want to create a new content type that have the Issue as its parent content type. So how I should be managing the two content types (parent and child) in the following scenarios:-
If I want to add a new site column to the child content type, should I add it directly to the child content type or I should added to the parent content type?
If I want to change the “Column Settings” for a field such as if it is optional, required, hidden should I do it at the parent or at the child content type.
Let say I created 3 issue tracking lists based on the custom content type which i have created and which have the Issue as it parent content type. Where each issue tracking list will have different values for the Priority site column. So is it a bad practice to modify the Priority values at each list level , where the Priority will have different values at each of the list levels ? Or it is better to create a new Priority site columns for each list. in other word should I always create new site columns or it is better to modify the same site column at the list level ?
Can anyone advice ?
