Developing requirements > NX design and validation requirements

Create an NX validation requirement

Note: You can create validation requirements only in Systems Engineering.

Procedure

Select the node where you want to create the validation requirement at the next lower level, and then do one of the following:
- Choose File→New→Requirement.
- Click the Create a new requirement button on the toolbar.
Note: You can also create a validation requirement from the Quick Create bar in the Requirements view.
In the Requirement Type dialog box of the New Requirement wizard, select Validation Requirement and click Next.
In the Requirement Information dialog box, enter the following information for the new requirement.

Field name	Definition	Valid values
Description	Description of the requirement. Text typed into this box becomes the initial body of the requirement.	Alphanumeric (1–240 characters)
Name	Name of the requirement (required).	Alphanumeric (1–128 characters)
Requirement ID	Requirement ID (required). To fill in the Requirement ID box automatically, leave it empty or click the Assign button. Systems Engineering inserts the next identifier in the sequence and the current revision. The prefix REQ- precedes the identifier. (The default prefix is set by the Default Requirement ID Rule naming rule.)	Alphanumeric (1–128 characters)
Unit of Measure	Unit of measure for the requirement. Not valid for a design requirement.	—

In the Define business object create information dialog box, enter the following information for the new requirement.

Field name	Definition	Valid values
Requirement Formula	Requirement formula.	Alphanumeric (1–240 characters)
Revision	Requirement revision (required). To fill in the Revision box automatically, leave it empty or click the Assign button. Systems Engineering inserts the current revision.	Alphanumeric (1–128 characters)
Severity	Severity level of the requirement (required). The severity specifies the degree to which a validation failure creates a problem.	0/Error, 1/Warning, 2/Information

In the Define Variables dialog box, click the button to create a new variable.

Note: For variables in validation requirements, certain Teamcenter preferences set the default variable type, measurement type, and unit type. If you have questions about variables, consult your Teamcenter administrator.
Enter the variable information. You can continue to click the button and enter the variable information until you have added all of the variables that you need for the validation requirement.
Click Finish to complete the new requirement and close the wizard.

The new requirement occupies the last position at the selected level.

You can click Close to close the New Requirement wizard, or repeat steps 2 through 7 to create another requirement.

(Optional) Edit the content of the requirement specification in either the MS Word view or in a separate Word window.
