**below the specified field**. g_form.addInfoMessage() or g_form.addErrorMessage() place a blue box message at the top of the screen. Pg 126 of the CAD handbook The method that prints a message on a blue background to the top of the current form by default is g_form.addInfoMessage(). The g_form object is a global object that provides access to form fields and UI elements on a form. The addInfoMessage() method is a method of the g_form object that displays an informational message next to the form header. The message has a blue background color by default, unless it is overridden by a CSS style. The addInfoMessage() method takes one argument, which is the message text to display.

The following roles grant access to source control repository operations such as importing applications from source control, or linking an application to source control:
source_control. This is a role that allows users to perform basic source control operations, such as importing an application from a source control repository, updating an application from a source control repository, or committing changes to a source control repository.
admin. This is a role that grants full access to all the features and functions of the ServiceNow platform, including source control operations. Users with this role can also perform advanced source control operations, such as creating or deleting source control repositories, configuring source control properties, or resolving conflicts.
The following roles do not grant access to source control repository operations:
source_control_admin. This is not a valid role in ServiceNow. There is no separate role for source control administration, as this function is included in the admin role.
git_admin. This is not a valid role in ServiceNow. Git is a specific type of source control system that ServiceNow supports, but there is no role dedicated to Git administration. References: Source Control, Source Control Roles

It is best practice to define the business requirements and the process(es) an application will manage as part of the application development plan. The following are some of the considerations to document as part of the business process:
Business problem. This is the description of the problem or opportunity that the application is intended to address or exploit. It should include the background, context, scope, and objectives of the problem or opportunity.
Data input/output. This is the specification of the data that the application will need to collect, store, manipulate, and display. It should include the data sources, formats, validations, transformations, and integrations of the data.
Users/stakeholders. This is the identification of the users and stakeholders who will be involved in or affected by the application. It should include the roles, responsibilities, expectations, and needs of the users and stakeholders.
Process steps. This is the definition of the steps and activities that the application will perform or support. It should include the inputs, outputs, triggers, conditions, and outcomes of each step or activity.
The following are not some of the considerations to document as part of the business process:
Project schedule. This is the estimation of the time and resources required to complete the application development project. It should include the milestones, deliverables, dependencies, and risks of the project. This is not part of the business process, but part of the project management plan.
Database capacity. This is the measurement of the amount of data that the application will generate and store in the database. It should include the data volume, growth rate, retention policy, and backup strategy of the data. This is not part of the business process, but part of the technical design and architecture of the application.
Available licenses. This is the number and type of licenses that the application will consume or require from the ServiceNow platform. It should include the license model, cost, and allocation of the licenses. This is not part of the business process, but part of the financial and legal aspects of the application.
