definition chart

Error In:
Correctness
Description:
There are elements that flow to or from both an instance activity and an external activity in the off-page definition chart, but the source or target name in the off-page definition chart is not the same as the name or synonym in the instance chart.
This check is performed only when you specify with definition charts. The error is reported in the instance chart.
Example:
In the following figure, this error is generated when testing chart A2, where IN_FLOW flows from external activity INPUT_1 to instance activity ACT_1. However, in the off-page definition chart, IN_FLOW is shown flowing from external activity INPUT_2.
Erroneous Elements:
Events, conditions, data-items, information-flows, and fields
