While dealing with filtered index following Six SET option’s value should be set to ON
SET ANSI_NULLS ON SET ANSI_PADDING ON SET ANSI_WARNINGS ON SET ARITHABORT ON SET CONCAT_NULL_YIELDS_NULL ON SET QUOTED_IDENTIFIER ON
And the one SET option whose setting value should be off is:
SET NUMERIC_ROUNDABORT OFF
If these settings are not set properly then filtered index creation may fail, query execution may not use the index or DML operation on the table may fail. The DML operation may fail with a error message like below:
INSERT/Update failed because the following SET options have incorrect settings: ‘QUOTED_IDENTIFIER’. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or filtered indexes and/or query notifications and/or XML data type methods and/or spatial index operations.
