Note: Using filters in the Functional Unit Area Configuraiton dialog is similar to using them in the Feature Table (see Working with filters in the Feature Table). However, there is also a subcatchment filter to help you find subcatchments either by name or by using the subcatchment map, see Subcatchment filter. |

Note: After a Functional Unit (FU) was deleted from FU list, that FU was automatically removed from Rainfall and Runoff model, and Constitute model. However, the deleted FU cannot be automatically removed from Scenario Input Sets where it is used. The user needs to manually modify the Scenario Input Sets for the deleted FU. |
Rename FUs
The user can click on the FU name, which needs to be renamed, from Functional Units list (3 in Figure 4) first, then selected FU name will be displayed in the textbox under Functional Units list (4 in Figure 4) under Functional Units list. The user can then rename this FU in the textbox and the Delete button (5 in Figure 4) will be changed to Rename button. Clicking on Rename button will rename the selected FU (3 in Figure 4) by modified FU name in the textbox (4 in Figure 4). Click OK button to save the modification.
