Revise a parametric requirement

To modify the data for a parametric requirement, you must first create a new revision of the parametric requirement.

Procedure

1. Select the source requirement item or item revision, and then choose File→Revise to open the Revise wizard.

2. (Optional) In the Define the basic information for the new item revision pane, type the name of the new revision.

3. (Optional) Type a description of the revision and choose a unit of measure for the revision.

4. Click Next to open the Define additional item revision information pane.

5. (Optional) Enter values for the requirement revision attributes.

6. Click Next.

   The Define attached objects pane displays the source revision and attachments and the destination revision and attachments. By default, all objects are copied forward to the new (destination) revision.

7. (Optional) Choose copy options for the objects related to the source revision by clicking the icon to the right of the object in the tree:

   Icon	Description
   Don't Copy	Allows you to selectively copy objects from one revision to another. Objects designated as Don't Copy appear with a line through them in the Destination tree.
   Copy as Object	Creates a new object of the same type and relation to the parent object. Objects created by this method are totally independent of the parent object — changes to the copied object are not reflected in the original object. Copied objects appear in bold in the Destination tree and can be renamed.
   Copy as Reference	Copies the object as a reference to the original object. All changes to the reference copy affect the original object. The names of attachments that are copied as references cannot be modified.

8. Click Next. The Select projects or programs that you want to assign new object to pane is displayed.

9. (Optional) Assign the new revision to a different project or program.

10. Click Next to open the Select open option and alternate id display option pane.

11. (Optional) Set the open, display, or check-out option for the new revision.

12. Click Finish.

Results

The new revision is created as a copy of the source revision and is opened in Systems Engineering. You can edit the new revision's Body Cleartext property to enter new parameters or change existing ones.

The new revision is independent of the source revision. Modifications to the new revision are not reflected in the source.
