create — Creates a sub-scenario.

delete — Deletes the sub-scenario identified by the value of the instance id parameter.

delete all — Deletes all sub-scenarios that this scenario block manages. The sub-scenarios that a scenario block manages are the sub-scenarios that the scenario block created and has not yet deleted. A main scenario can use two or more instances of the same scenario block. Each scenario block manages only the sub-scenarios it creates. In a main scenario, the A1 scenario block has no information about sub-scenarios created by the A2 scenario block.

retrieve — Retrieves the sub-scenario identified by the value of the instance id parameter. The retrieved sub-scenario becomes the context instance. To modify any values associated with a sub-scenario, the sub-scenario must be the context instance. The retrieve operation does not modify the current values of the scenario block's parameters.

commit — Changes and saves the values of the context sub-scenario's input variables that correspond to scenario block parameters whose values have changed since the previous create, iterate, next, retrieve, or commit operation, whichever came last.

iterate — Starts an iteration through the sub-scenarios that this scenario block manages. After you call the iterate operation, the first sub-scenario that the block created is the context sub-scenario. You do not need to call the next operation to retrieve the first sub-scenario. To restart an iteration, call the iterate operation again.

next — Moves to the next sub-scenario in the iteration and makes that sub-scenario, if there is one, the context instance. The next operation visits the sub-scenarios in the order in which the scenario block created them.
