ServiceNow supports publishing an application to an application repository, an Update Set, or the ServiceNow Store. These methods allow the application to be installed on other instances or shared with other users.

4 Ways to Publish a ServiceNow Application

Publish applications to the ServiceNow Store

In ServiceNow, when a table is extended from a parent table, it inherits all fields from the parent. These inherited fields are integral to the structure of the child table and maintain the relationship between the parent and child tables. As a result, inherited fields cannot be deleted from the child table.

Key Points:

Inheritance Structure: The child table's structure is designed to include all fields from the parent table to preserve data integrity and ensure consistent behavior across the hierarchy.

System Constraints: ServiceNow does not provide an option to remove inherited fields from the child table. Attempting to delete such fields would disrupt the inheritance model and potentially cause system inconsistencies.

Alternative Approaches: While you cannot delete inherited fields, you can manage their visibility:

Form Layout: Adjust the form layout to hide inherited fields that are not relevant to users interacting with the child table.

Access Controls: Implement access controls to restrict visibility or edit permissions for specific fields based on user roles.

In ServiceNow, a workflow context refers to a specific instance of a workflow execution. When a workflow is initiated—whether by inserting or updating a record, triggering an event, or through scripts—the system creates a workflow context. This context is derived from a particular version of the workflow and is responsible for executing the defined activities and following the specified transitions within that workflow.

Key points about workflow context:

Instance of Execution: Each time a workflow runs, a new context is created to manage that specific execution instance. This allows multiple instances of the same workflow to operate independently and simultaneously.

Execution of Activities: The context manages the progression through the workflow's activities, ensuring that each step is executed in the defined order and under the specified conditions.

Tracking and Management: Workflow contexts enable administrators to monitor the state and progress of workflow executions. They provide visibility into which activities have been completed, which are pending, and any transitions that have occurred.

For example, if a workflow is designed to handle approval processes, each time an approval is initiated, a new workflow context is created to manage that particular approval instance. This context will track the approval's progress, manage notifications, and handle any branching logic defined in the workflow.
