This column contains a logical expression evaluated at the moment of signature. If the condition is met, the answer defined on the line is suggested among the possible choices. This is useful, for instance, to have available several levels of signature, depending on the number of signers having already signed (only the last signer having access to a signature triggers a final update). Likewise it is possible to define a seemingly impossible choice (by means of an always wrong condition of type 1=0). This choice may be forced using a signature action triggered by another Workflow event. Escalations in signature processes are dealt with in this manner in standard parameterizations.
