When modifying field properties, consider the following:
- Depending on whether or not a given field has been spread down to the current family from a higher-level family, some field properties may not be editable.
- Some attributes of baseline fields cannot be modified. If you attempt to make a modification that is not allowed, an error message will appear, and your change will not be saved.
- Some baseline fields cannot be modified because they belong to a family that has been delivered with read-only properties. When you view the properties for a field that meets this criteria, some field properties will not be editable.
