@sameer for all 500 series response codes (500, 501, 503, 504) your system has to retry submitting invoice without making any changes (no changes even in the technical identifiers such as UUID, ICV, PIH and hash).

Dear @Ankit.K.Tiwari thank you for support.

In this case, can we save the tax invoice in the system while ensuring that:

  • The invoice is not shared with the buyer.

  • The invoice will actually affect the accounts, including tax accounts.

  • Sending the invoice later for clearance

Continuing to issue invoices without causing 5xx cases to stop issuing tax invoices.

If the invoice is rejected later, and because the system does not allow invoices to be modified, we will be forced to make available the option to modify invoices that are rejected after they are saved.

We need your support on this scenario because we are indeed forced to do so, but we do not want it to conflict with compliance rules.
