Report of the Consistency Checks Once the initial selection process has been done a consistency check is performed on this chosen sub-set Functional Viewpoint. It is not unusual to find that: * Data Flows do not have a source and/or a sink (target) - this could be a Function, Data Store or Teminator; * Functions may not have any Data Flows associated with them; * Data Stores may not have any Data Flows associated with them. It is therefore necessary to resolve these inconsistencies by adding, or subtracting, elements to, or from, the sub-set Functional Viewpoint. In order to do this it is necessary to go back to an earlier part of the process to modify the selection. It can be useful at this stage to view the elements that have been selected so far; this can be done by producing one or more "Reports" from under the "Tool" command. Close
