What are 'Process Variables' in the Appian context?

Process Variables in Appian are essential components that serve as temporary data storage during the execution of a process. When a process is initiated, these variables hold values that can be used throughout the lifecycle of the process workflow. This could include information such as user input, system-generated data, or outputs from various tasks within the process.

The nature of process variables allows them to be ephemeral; they exist only for the duration of the process instance and are not intended for long-term data retention. This characteristic is crucial for maintaining data integrity and for the dynamic nature of process execution, where the values may change as the process moves through its various stages.

In contrast to permanent storage solutions or data representation in user interfaces, process variables are specifically designed for temporary holding and managing data that directly influences the decision-making and operational flow within a process. Thus, when a process completes, the process variables typically cease to exist, making them distinct from other forms of data management within the Appian platform.
