General Parameters
To make reusable some values, there is the possibility to use them as general parameters, that means make them visibile across some Supervisor functionalities (i.e. Activities and Tasks).
To create a new general parameter, open the General Parameters form via the path Configuration > Parameters > Supervisor > General Parameters. All the functionalities inside the form refer to a standard use, therefore for anything not detailed in this document on the standard functions of the form, refer to the following link functionalities, buttons and common entries.
