I’m unable to create a BIRP/PIE/UNI note because ShareNote is saying that the date and time overlaps with another client. (Location User)

This message means that there is either a note for the same consumer for the same time done by another staff, or that there is another note done by you for the same time. You will have to speak with your supervisor/administrator to clarify the situation and correct it so that you can submit your note.
