FullyPaidOnDate отличается при получении одного счета-фактуры от сбора счетов-фактур, когда ему выделяется кредитная нота

Question

Когда у меня есть счет-фактура, который полностью оплачен с помощью распределения кредитной ноты, FullyPaidOnDate при получении одного счета отличается от того, что он есть при получении коллекции счетов-фактур.

Кредит-нота выделяется как как только счет будет создан.

1. При получении отдельного счета FullyPaidOnDate совпадает с датой счета-фактуры.

2. При получении Для сбора счетов дата FullyPaidOnDate совпадает с датой кредитной ноты.

Есть ли причина для разницы?
