When you select this option, you are allowing your work to be used or viewed by other users within the practice or practices you designate. For example, if you save a custom flowsheet as Practice, that flowsheet is available for other users to view from the Flowsheets module.
If you are associated with more than one practice, the LMR also prompts you to select the practices that you want to authorize for use of the custom flowsheet. To select multiple practices, hold down the CTRL key while clicking.
