Moving down the conditional flow is done upon fulfilling the condition specified for a flow. For example, if a customer is interested in your products or services, the relevant information must be forwarded to them (Fig. 73).
Conditions for gateways are set in the same manner. If a process element (for example, “Perform task”) is connected to a gateway with a sequence flow, then when you add conditional flows between this gateway and subsequent process elements, it is necessary to specify the conditions for moving down these flows.
Conditions of flows
Depending on the element they originate from, the conditional flows can be assigned conditions by selecting a preset condition in the element setup window of a conditional flow, or specifying a custom condition using a formula.
Selecting a condition from the list
When you add an outbound conditional flow to an action, such as [Perform task], you can select task results as a condition for activating this conditional flow. In the same way, you can select a column to generate the list of results for conditional flows when adding an [Open edit page] element. The selected option will be used as a condition for activating this conditional flow (Fig. 74).

Note
Possible results of the [Perform task] element are stored in the [Activity results] lookup. The list of possible options depends on the type of activity.
In this case only one of the outgoing conditional flows can be activated, as with an exclusive gateway.
Using a formula to create a condition
If a conditional flow originates from any process element whose results cannot be determined by the value in a certain column, you need to specify the condition using parameter value window. Formulas are also used for conditional flows outgoing from gateways.
When you add such a conditional flow, the [Formula] element card is opened. Use it to set conditions for moving down this flow ().
When a formula is used to set conditions for conditional flows, the result of the formula is treated as a Boolean value. The logic is the same as that of the standard [Formula] item whose value is passed to a parameter with the boolean data type.
