Insufficient privileges when adding FK constraint (Oracle)

Question

ALTER TABLE LAB_ADMIN_USER.TEST_TEMPLATE_ABBR ADD (    CONSTRAINT TEST_TEMPLATE_ABBR_R01  FOREIGN KEY (test_template_id)  REFERENCES LAB_ADMIN.TEST_TEMPLATE (test_template_id)    ON DELETE CASCADE) 

What is the most likely cause of 'ORA=01031: insufficient privileges' when executing the command above? In other words, what permission does LAB_ADMIN_USER most likely not have?

I already created the table successfully and attempted to add the FK constraint as LAB_ADMIN_USER.

Answer 1

The table with the primary key is owned by a different schema - LAB_ADMIN. That user must grant REFERENCES on TEST_TEMPLATE to LAB_ADMIN_USER.
