Field ACL (write) not working as expected in custom table

Hi All,

I am trying to restrict write access to a specific field using ACL, but it is not working as expected.

Requirement:
Only users with the ITIL role should be able to edit the Department field in a custom table (Test SNOW). All other users should have read-only access to this field.

So what will be approach to this requirement.I want to use only ACL.

 

Any guidance or suggestions would be really helpful.

Thanks in advance!

A single field-level write ACL on that one field should do — leave the existing table-level write ACL alone so non-ITIL users can still edit other fields.

as security_admin 

 

1.  ACL > New
2. Type: record, Operation: write
3. Name: u_test_snow . u_department (use the actual table/column names from sys_db_object and sys_dictionary — replace if different)
4. Required Roles: itil

 

ACLs are evaluated table-first, then field. Non-ITIL users pass the table-level write ACL (form stays editable) but fail this field-level write ACL, so only the Department field becomes read-only for them. Read access is unaffected.
