Why are the category and subcategory fields in CSM case field are type Integer instead of String like other modules (e.g. incident, change request)?Summary'Category' is used as a choice field in all of these tables - the underlying value (string / integer) is different. They both provide the same function, though interacting with these items through script may be different. Design-wise it may be easier to extend/override an integer choice with simpler data, but that difference is negligible. Again, both provide the same function.
