Application Access settings on a table control which operations external applications (in other scopes) can perform. The main controllable operations are:

Can create

Can read (query)

Can update

Can delete

From Development Handbook 4.0.4, p. 192:

“Application access settings determine whether another scope can read, write, create, or delete records from this table... Execute is not a valid database operation — it pertains to script includes or other executable logic.”

Self-invoking. Learn JavaScript!

This type of JavaScript function is known as self-invoking or immediately-invoked function expression (IIFE). It is a function that is defined and executed at the same time, without being assigned to a variable or being called by another function. It is often used to create a local scope for variables and avoid polluting the global namespace. References: [W3Schools - JavaScript Function Definitions], [MDN Web Docs - Immediately-invoked function expressions]

Inherited fields in ServiceNow are fields that are part of a parent table and automatically become part of child tables through inheritance. This structure is foundational in the ServiceNow data model, ensuring that child tables maintain a consistent relationship with their parent tables.

Here’s why inherited fields cannot be deleted from a child table:

System Design:ServiceNow employs a table inheritance model where child tables derive fields and properties from parent tables. Deleting inherited fields from a child table would break the integrity of the data model, as those fields are shared across multiple tables.

Impact on Functionality:Many inherited fields, such as sys_created_on or sys_updated_by, are integral to the functionality of the platform. Removing them could disrupt workflows, reporting, and auditing capabilities.

Alternative Approach:If you want to hide or restrict access to inherited fields in a child table, you can use ACLs (Access Control Lists) to prevent users from viewing or modifying these fields. Another option is to use UI Policies or Client Scripts to control their visibility on forms.

Developer Note:Attempting to delete inherited fields violates ServiceNow’s core principles of maintaining a robust and unified data structure. The platform enforces these rules to ensure consistent behavior across all tables in the hierarchy.

To include specific records from a table (often referred to as seed data) when distributing an application in ServiceNow, developers must add these records to the application as application files. This ensures that when the application is installed on another instance, the specified records are included.

Option C is correct because using the "Create Application Files" feature allows developers to select specific records to include in the application package. This process creates application files for the selected records, ensuring they are installed along with the application on other instances.

Options A, B, and D are incorrect:

A: The activation status of Table A and whether it extends the Task table do not determine whether its records are included during installation.

B: Having an automatic number counter and setting a table property do not control the inclusion of records in the application package.

D: The System Clone > Exclude Tables list pertains to cloning operations and does not affect application installation.

For detailed guidance on including table records in application deployments, refer to the official ServiceNow documentation:

In the SOAP Message feature set, we indicate variables using the following syntax: S{variable_name}. This allows us to pass a variable with the specified name from the SOAP message record to the web service function.

In ServiceNow, Access Controls (ACLs) are used to manage permissions for various database operations on tables and their records. The primary operations that can be controlled include:

Create:

Description: Permission to insert new records into a table.

Control: ACLs can be defined to allow or deny users the ability to create records based on roles, conditions, or scripts.

Update:

Description: Permission to modify existing records in a table.

Control: ACLs can restrict who can update records, ensuring that only authorized users can make changes.

Other Operations:

Read: Controls the ability to view records in a table.

Delete: Manages the permission to remove records from a table.

Incorrect Options:

Execute: Not a standard database operation controlled by ACLs in ServiceNow.

Query: While querying is part of the read operation, ACLs specifically control the read access rather than the query process itself.

"A table that extends another table is called a child class, and the table it extends is the parent class" - this is about halfway down in this link below: https://docs.servicenow.com/en-US/bundle/tokyo-platform-administration/page/administer/table-administration/concept/table-extension-and-classes.html

The ServiceNow platform is designed to create applications that use forms, workflow, and reporting to solve business problems. Forms are used to interact with data stored in tables, workflow is used to automate and orchestrate processes, and reporting is used to visualize and analyze data. The platform does not require low-level programming libraries or multimedia features, as it provides standard tools and technologies for application development.
