WMChangeActivityInstancesState WMChangeActivityInstancesStateThis call changes the state of the activity instances of a particular name associated to a process definition that match the specified filter criterion.
This command directs a WFM Engine to change the state of the named activity for a set of activity instances. It is assumed that a person who can change the state of the set of activity instances corresponding to a process definition has special authorization to do so. If the implementation supports a state such as suspended, and resumed or in-progress, then the calls for suspend and resume are implemented as state change calls. If the filter pointer pact_inst_filter is NULL, then the command is applied to all activity instances of the given activity definition.
You can view the XML input and output parameters, which have to be passed for changing the activity instance. There is a list of errors and warning that can occur in the execution.
