This article provides a comprehensive guide on how to create a new module in ServiceNow and configure its access controls effectively. By following these step-by-step instructions, you can ensure that your modules are secure and accessible to the right users.

Define Module Requirements:

Before creating a new module, clearly define its purpose and functionalities. Determine what type of data the module will store and the actions users can perform. Consider how the module fits into the overall ServiceNow instance and aligns with your organization's processes and workflows.

Access Module Builder:

In ServiceNow, access the Module Builder by navigating to "System Definition" -> "Applications" -> "Module Builder." This tool allows you to create and configure modules seamlessly.

Create a New Module:

Click on the "Create a new module" button in the Module Builder. Provide a name for your module and a short description to help identify its purpose. Specify an icon for the module to enhance its visual representation within the platform.

Design Module Hierarchy:

If your module requires a hierarchical structure, define its parent and child relationships. This hierarchy aids in organizing data and allows users to navigate through related modules easily. Configure the appropriate relationships based on your module's requirements.

Define Module Fields:

Identify the fields necessary to capture the relevant data for your module. Click on the "Add Field" button and specify field attributes such as name, type, length, and mandatory status. Consider using field types that align with the data you intend to capture, such as text, choice, date/time, or reference fields.

Configure Module Access Controls:

Access controls ensure that the right users have appropriate permissions to view, create, update, or delete records within the module. To configure access controls:

1. Navigate to the "Security" tab within the Module Builder.
2. Define roles that will have access to the module. Examples of roles can include "Admin," "Manager," "User," or any custom roles specific to your organization's needs.
3. Assign access rights to each role by selecting the desired permissions for the module, such as read, write, create, delete, or customize.
4. Consider granting additional access controls at the field level, restricting specific fields to certain roles if required.
5. Implement field-level and record-level access controls using conditions and scripts to further refine access based on specific criteria.

Test and Validate:

Thoroughly test the module and its access controls to ensure they function as expected. Log in with different user roles and verify that users can access the module according to their assigned permissions. Create test records, modify data, and delete records to validate that the access controls restrict or allow the actions appropriately.

Document and Communicate:

Document the module's purpose, fields, access controls, and any related procedures or guidelines. Provide clear documentation to users, explaining how to access and utilize the module. Communicate any changes or enhancements to the module to relevant stakeholders to ensure a smooth transition and adoption.
