Triggers are used to initiate or cancel certain actions for an account, account host, account type or system in a resource assessment system. This page provides details of the different types of triggers available in Resource Assessment systems, along with types of actions that can be initiated.

| Condition | Description |
|---|---|
| End of water year | Triggers an action at the end of the water year. |
| Function | Triggers an action using a defined function. The format of a function should be as follows: if( A > B,1,0), where “1” indicates the action will occur and “0” means the action will not happen. |
| Monthly trigger* | Triggers an action for a particular month. You must specify the offset from the start, along with the number of days. |
| Per-timestep | Triggers an action per a specified number of time-steps. For example, if a monthly model, triggers an action per month or per several months. You can choose to reset the repeat interval at the start of each water year. |
| Season | Triggers an action for a specified season. You must define and start and end dates. |
| Specified date | Triggers an action on a specified date. |
| Start of water year | Triggers an action at the start of the water year. You can choose to repeat the action at a specified number of timesteps, and whether to reset the repeat interval at the start of each water year. |
| Storage level | Trigger based on a specified storage level. You must specify the storage, the level and whether the level is rising or falling. |
*Note that: since Source V4.9, for Monthly trigger condition, the offset “end of the month” is no longer being supported although this option is in item is in the dropdown list of the user interface. Instead, the user can use the following: Condition: Monthly Trigger; Offset From: Start Of The Month; Execution: Timestep End; Days Offset: 0;.
Trigger actions
There are a total of ten trigger actions available in Source (Figure 1), each having an individual set of definable parameters. All triggers can be applied at the system, account type, or account level. The exceptions are the reassessment and the Vic Carryover triggers, which are available at the system level only. Note that although Vic Carryover appears as one option item on the user interface at all levels, the interface will display the system level if this item is selected.

Independent mapping (Figure 5) allows you to map between accounts, account types or account hosts to other accounts, account types or account hosts within or between accounting systems. Note that the Source system will always be the system in which the trigger is located. The source and destinations do not need to be the same level - eg. an account type can be mapped to two accounts in another accounting system (Figure 15).
One-to-one mapping (Figure 4,Figure 6) allows you to map accounts, account types or account hosts to others of the same level - eg. you can map an accounts to other accounts. This allows you to create multiple triggers of the same type at once. When you select this option, the Source and Destination will be the same, that is, an item will map to itself. You can change the mapping by reordering either the source or destination by clicking a cell and dragging it next to the desired item. For example, in Figure 54, the Destination accounts for the HRWS account type were dragged to be next to their corresponding accounts for the LRWS account type. To enable the trigger for a mapping, toggle on the Checked box next to that entry.
