If the delivery scheduling feature is in use and delivery capacity is enabled, there are two known scenarios that can make the window available even after it has reached its maximum configured capacity limit. The scenarios are: Shipping policy id with a space or too many characters making up the string, AccountName+ShippingPolicyId cannot exceed 60 characters.

Create a shipping policy and, in its Id, insert a space, or AccountName+ShippingPolicyId resulting in more than 60 characters, configure scheduled delivery and delivery capacity. Place orders by selecting the registered window, check that it will be possible to create more orders than the maximum configured in the delivery capacity. At checkout, when the configured limit is reached, the window should not become unavailable, but will remain visible and can be selected.

Do not register any Id with a space in the shipping policy or with more than 60 characters adding together the characters in the AccountName+ShippingPolicyId.
