Not all procedures results in a verdict. If the purpose of the procedure is to perform a simple task or to make an estimate, there is in fact no need for it to give a verdict.
Try for example the following:
1 Mark the procedure header, in case this is not already active.
2 Uncheck the box Has Verdict on the tab General in the Proper ties window.
3 Execute the same procedure again and notice that the result is now Unset.
