Entity activity_template_constraint

• A logical dependency of a typical activity for a specific template. This enables the expected order of the typical activities contained in a template to be defined.

Attribute                                 Flags   Data Type

From association:
   data_collection                        IV      set[0 .. N] of (data_collection)

                                          Indicates the data collections that include this
                                          instance of E and P data. 

   graphical_element                      IV      set[0 .. N] of (graphical_element)

                                          Specifies one or more graphical elements which
                                          are depicting this data item. 


activity_duration                         N       ndt_day_interval

                                          The duration of the constrained activity of the
                                          template constraint. This may act as an upper
                                          limit, a lower limit or both. The limit type is
                                          specified by the constraint kind. 

description                                       ndt_comment

                                          A description of the template constraint. 

ref_template_constraint_kind              MU      ref_template_constraint_kind

                                          The type of constraint. This defines how the
                                          constrained and constraining typical activities
                                          constrain each other. For example, the constrained
                                          must start after the end of the constraining.

relative_time                             N       ndt_day_interval

                                          The time interval between the constrained activity
                                          and either the constraining activity or the absolute
                                          time for the template constraint. The role of
                                          the time interval is given by the constraint kind.

activity_template                         MU      activity_template

                                          Gives the template that the template constraint
                                          is valid for. A template constraint is only valid
                                          for one template. 

constrained_by                            U       typical_activity

                                          Indicates the typical activity that acts as the
                                          constraining activity of the template constraint.

constraint_for                            MU      typical_activity

                                          Indicates the typical activity that acts as the
                                          constrained activity of the template constraint.
