The Multiple Clients indicator allows an administrator to define whether a single client or multiple clients can be selected when adding the action to an outcome plan. If this indicator is switched on, multiple clients can be added to the action. A multi select list is provided when adding the action to an outcome plan which allows multiple clients to be selected. If this indicator is switched off, only one client can be selected when adding an action to an outcome plan. A drop down list is displayed allowing only one client to be selected.
