Purchase invoices after Comply with E-Invoicing

Dears,
I am using cloud version.
After register with ZATCA for E-Invoicing as a system, I found that when I create a purchase invoice I can’t add the invoice date or number. And that will not help if I checked about invoices by date of issuance, or invoice number. Those invoices come from suppliers.

For now,
Open Custom field Settings, remove placement on Purchase Invoice and Debit Note for all custom fields

Many thanks.
