Variable and field values updates through the run script in the workflow are occasionally failing Issue Updates to the variables or filed vales are occasionally failing.CauseUpdates on the RITM are aborted through business rules.ResolutionUpdates performed on the RITM through workflow are triggering a business rule either on the sc_request or sc_req_item or task tables which contains the "AbortAction" script. As most of the workflow activities execute in the same second all the updates are carried at the same time when the abort action is performed which results in the updates not being carried to the RITM. When you Added a 1-second timmer between the activity the issue will be temporarily fixed as some times the timer activity is processed fast which caused in this issue. In order to resolve the issue, increase the timmer duration to 5 seconds or add a timmer activity before and after the activity that is triggering the abort action business rule.
