Cannot set item default role permission

Hi all,

I cannot set item default to role permission. The document type kept blank no matter I use Chrome or Safari & blocking me to add a new permission rule.

Anyone facing that too & any solution?

Thanks in advance,
Cher

Because Item Default is a child table, you can set role permissions for it in the child table itself. You can apply these permissions to the Item doctype. Otherwise, you will need to apply field-level permissions.
