[Nirvisha_Soni]

 let df = frappe.meta.get_docfield("Child Table Name","child_table_field", frm.doc.name);
        df.get_route_options_for_new_doc = function (field) {
            return {
                "field_name": value
            }
        }

Child table name would be Purchase Receipt Item
child. table field would be cats_doc
