Correct statements:
You can only create one initial state, yet it is possible to have more than one Final State. You can only create one link from Start, so it is impossible to connect more than one initial state to it. However, you can connect a State activity to the different Final States depending on the required conditions.
Every State Machine must have a Final State to avoid an infinite loop. If you interconnect States between each other without a Final State, then the process will enter an infinite loop, which would result in incorrect processing.
Every State activity should have at least 1 transition. If you do not create a transition, a red symbol of an error will appear in the corner of the State.

Incorrect statement:
You can directly connect Start and Final State. That is an incorrect statement, as Final State cannot be an initial state. UiPath Studio does not allow to create a link directly from Start to Final State.

To set date since when a transaction item should be processed, use Postpone property of Add Queue Item activity. This property can be filled in with relative dates such as DateTime.Now.AddHours(2), DateTime.Now.AddDays(10) and DateTime.Now.Add(New System.TimeSpan(5, 0, 0, 0)). Additionally, you can use the US notation to add an exact time, such as 12/10/2017 07:40:00. Automatically correcting this date is available. For example, if you write 8 9 2018 9:0, it is automatically transformed to 08/09/2018 09:00:00.
In the United States, dates are traditionally written in the “month-day-year” order, so 7 1 21 8:0 will result in item being postponed till 1st of July 2021, when 1 7 21 8:0 will postpone it to 1st of January 2021.

When a selector is built, the Case-Sensitive property makes it possible to identify elements by also taking into consideration the casing of an attribute’s value.
In order to enable identification of attributes by casing, the case-sensitive() attribute needs to be included in the selector, in the tag of the target attribute:
casesensitive:=’false’
Enables you to validate a selector by also including an attribute’s value casing. By default, the value of this option is set to true. If set to false, the casing of the attribute’s value is not taken into account.

The following selector will be recognized by UI Explorer:

If capital letters are changed to lowercase, UI Explorer will not recognize this selector:

A Business Exception describes an error rooted in the fact that certain data which the automation project depends on is incomplete or missing.
Retrying the transaction does not yield any chance of solving the issue, and there are other better courses of action, such as notifying the human user of this error.
By default, Orchestrator does not retry transactions which are failed due to Business Exceptions. This happens because an inconsistency between the transaction value and the business requirement means that there might be errors in the initial data which the queue items were created from.
