How can a field group be modified for sharing between schemas of different class types?

Sharing field groups between schemas of different class types requires aligning the data types involved, which is achieved by converting the field group into a system data type. System data types are standardized within the platform and can facilitate compatibility across various schemas, allowing for effective data sharing and integration.

When a field group is converted to a system data type, it ensures that the group adheres to predefined formats and structures recognized by the platform. This conversion is crucial when dealing with disparate class types because it helps maintain consistency and integrity in the data being shared.

Other options don’t provide the necessary compatibility across different schemas. Merging schemas or creating a new field group may create complexities or redundancies, while simply renaming a field group does not change its fundamental data type characteristics and wouldn’t affect its ability to be shared effectively.
