Which workflow activity works with all tables?

The activity that works with all tables in ServiceNow is the User Approval activity. This is significant because it is designed to facilitate approval processes that are applicable across various record types in the platform. Since approvals are a common task that can be required for different operations—ranging from incidents and changes to service requests—the capability to work generically with all tables makes this option versatile and widely applicable in workflows.

The User Approval activity allows developers to manage approval requests efficiently, enabling the creation of dynamic workflows that can adapt based on the nature of the task or record being processed. This flexibility is an essential characteristic for workflow design, as it ensures that the same approval processes can be utilized regardless of the specific table or application context.

In contrast, the other activities, while useful, are generally not applicable to all tables. Data Import is specific to importing data into tables and is not a part of workflow activities but rather a data management function. Record Update, while used for modifying records, typically targets specific tables based on the logic defined in the workflow. Task Assignment pertains to tasks usually associated with task tables like incidents or change requests and is not universally applicable to all tables in ServiceNow.
