Is there supposed to be a record in the JTF_USER_HOOKS table for the CSI_ITEM_INSTANCE_CUHK package?

We want to use the CSI_ITEM_INSTANCE_CUHK to be called after updating the Ship To information of an IB item instance. According to document ID 970991.1, to get the hook working, the package body must be defined and probably enable the execute flag for records that should be executed. The flag can be updated as follows:

update jtf_user_hooks set execute_flag='Y' where upper(pkg_name) like 'THE_PACKAGE' and upper(api_name) like 'API_NAME'.

There is no record for CSI_ITEM_INSTANCE_CUHK package in this table, even though the package exists in the database.
