Two library settings are used to control the display of copy alert messages or copy location check in alerts when recording in-house-use in Evergreen.
Setting Display copy alert for in-house-use to true for an organization will cause an alert to appear with the copy’s alert message, if it has one, when recording in-house-use for the copy.
Setting Display copy location check in alert for in-house-use to true for an organization will cause an alert to display a message indicating that the item needs to be routed to its location if the location has check in alert set to true.
The settings are independent of one another because you may want to display one and not the other when recording in-house-use.
