TestComplete displays this message when you are trying to update parameters of a keyword-test Property Checkpoint operation from the test log, but TestComplete is unable to do that.
The error occurs if any of the operation parameters is specified by the test parameter or by a code expression and cannot be evaluated at design time. In this case, you have to open the keyword test for editing and change parameter values manually.
