(C4061) Elements that are input to an activity and output of another activity without a flow-line between the two activities
If an activity that is a source of one flow-line changes the value of the element and this value is used by a target activity of the other flow-line, the drawing might be misleading.In Figure a,X
is changed by activityA
and is used byD
, but there is no flow-line betweenA
andD
. Therefore, an error is generated.However, the separate flow-lines in Figure b are allowed because they have the same source. Therefore, no error is generated.
