When we create direct debit mandates via OData interface, but it fails because the "Status" field is marked as read-only, but even Status is not specified on OData body, the request returns the error "insert not allowed for field 'Status'".

However, even when we tries to import only 3 fields (Account ID, Bank account and Mandate ID), without any intention to import Status, then also system is throwing an error.
Even when using excel, by removing Status field or leaving field blank, we still get status error appearing.
