In order to use the result after a process node executes, you must do what?

To utilize the results after a process node executes, it is essential to save the value into a process variable. This is fundamental in Appian's process design as process variables act as storage containers for data generated or modified during the execution of a process. By storing the result in a process variable, you ensure that it can be accessed later in the process flow, whether for further processing, decision-making, or displaying to users.

Saving results into process variables enables seamless data transfer between different nodes within the same process, allowing subsequent nodes to reference this data without re-executing any steps. This practice not only improves efficiency by minimizing duplication of effort but also enhances data integrity throughout the process flow.

While logging results to an external database, displaying results to the user, or sending results in an email notification are all valid actions that can be taken post-execution, they do not directly ensure that the results are retained for further use within the context of that specific process. Therefore, directly saving the results into a process variable is the most appropriate action to ensure that the data can be effectively utilized later in the process.
