The EPO_EVENT_AUTO_ID field in the SCOR_EVENTS table of the ePO database is missing the cascade option. The cascade option can't be applied because an FK constraint is present on the field.

To view the constraint, run the following command against the ePO database:
 
 SELECT  
     f.name AS foreign_key_name
     ,OBJECT_NAME(f.parent_object_id) AS table_name
     ,COL_NAME(fc.parent_object_id, fc.parent_column_id) AS
 constraint_column_name
     ,OBJECT_NAME (f.referenced_object_id) AS referenced_object
     ,COL_NAME(fc.referenced_object_id, fc.referenced_column_id) AS referenced_column_name
     ,is_disabled
     ,delete_referential_action_desc
     ,update_referential_action_desc 
 FROM sys.foreign_keys AS f 
 INNER JOIN sys.foreign_key_columns AS fc  
     ON f.object_id = fc.constraint_object_id  
 WHERE f.parent_object_id = OBJECT_ID('scor_events');

An appropriate output is similar to the example below:
