If a process model fails/terminates abruptly, (not in a regular way as shown below) at any stage, then corrective action is needed.
(If corrective action is not done, Process model will fail at duplicate check upon reprocessing as shown in below screenshot)
Corrective action: Pass the failed process model name in the highlighted node. Save it and run the analysis. (You have to retrigger the original PM which has failed, only after corrective action analysis is succeeded)
