Explanation
The administrator must configure "Appointments" in Routes and Schedule settings within Maps Configuration to ensure that a record is created for the custom object while creating a new visit plan for Maps Advanced.
This step allows the administrator to select a calendar object for output, which is the object that stores the visit records after route generation. The administrator can choose any standard or custom object that has a start date/time and end date/time field. This is explained in the Select a Calendar Object for Output document.

Explanation
According to the Salesforce Help article on Optimization in Salesforce Maps Territory Planning2, pinned area centers are fixed locations that optimization uses as starting points for each territory. This feature can be used to ensure that sales reps' homes are located within the boundaries of their respective territories whenever they run an optimization2. Pinned area centers can be set manually or automatically based on user location or other criteria2.

Creating a new alignment before optimizing on the correct attribute is the step that the user needs to take to return to the previous state prior to the optimization. A new alignment is a copy of an existing alignment that can be modified without affecting the original alignment3. The user can create a new alignment from the previous state and then run the optimization using the correct attribute. Clicking on the Undo button, creating a new data set, or re-running the optimization using the correct attribute are not valid steps, as they will not restore the previous state of the alignment.
