Adding a trigger to an account type
To add a trigger, right click on the account type and choose Add trigger. You can rename or delete an existing trigger by right clicking the trigger and choosing the appropriate contextual menu option.

| Note: An account can have several triggers, each can be designed to initiate a particular action. |
As shown in Figure 8, configure the following parameters under Trigger Configuration:
- Trigger - the type of trigger. For example, to trigger an action using a function, choose Function in the Trigger drop-down menu. The format of a function should be like this: “IF A>B, 1, 0”, where “1” indicates the action will occur and “0” means the action will not happen; and
- Execution - when to execute the trigger (ether at the beginning or end of the time-step.
The resulting Action Configuration panel will change depending on what is chosen under Trigger Configuration.
Once triggers are configured, you can prioritise them using the Trigger Priority tab (Figure 5).

Adding a usage limit to an account type
Right click the account or account type and choose Add usage limit. The GUI is similar for that in Continuous Accounting (here). You can limit water usage for all accounts by absolute volume or per-unit-share for moving water year or movable time window. An account can have several usage limits, each can be designed to initiate a particular limit. Just like triggers, you can rename or delete usage limits.
Triggers
Triggers are used to initiate or cancel certain actions for an account and can be added at any level in annual accounting. They are similar to the triggers created at the Account Type level (as shown in Figure 8) and can be managed at the
- System level (right click Annual Accounting and choose Add trigger from the contextual menu) - this is shown in Figure 9; and
- Account level - once an account has been created, right click the account and choose Add trigger. This is shown in Figure 10.
