Customising HHD flows with conditions

You can add conditions to your Handheld Device (HHD) implementation to control which screens users see or to enforce custom rules based on defined parameters — for example, restricting a specific account from accessing a particular screen.
1

Navigate to the implementation

From the Handheld Devices tab, go to Implementations. Select the implementation you want to modify.
2

Preview the flow

Scroll down to the Preview section. This shows a simulated view of the scanner screen. Click any option in Preview mode to simulate its functionality.

Edit a screen to add conditions

On the desired screen, click the Edit button. New icons appear next to each option:
  • Plus sign (+): Add new conditions or components
  • Pencil icon: Edit existing components
  • Trash bin: Delete existing components
  • Arrow icon: Navigate into the selected option
4

Add a condition

Select an existing component. A panel appears on the right-hand side — navigate to the Conditions tab. Click the Plus (+) sign next to Component Conditions to add a new condition.Define the condition parameters. For example, set task_account_code is equal to JOSEPH. This means only users on that account code will see the relevant screen content.
