--- alias: user-guide-mark-as-pilot-and-active tags: - versions - revisions description: "These operations toggle a revision between the Active and Pilot states, allowing a revision to be qualified before it becomes the default" --- # Mark Revision as Pilot and Mark Revision as Active :lock: *EntityTypeName*.**MarkRevisionPilot** :lock: *EntityTypeName*.**MarkRevisionActive** A **Pilot** revision can be selected and referenced by other objects, like an Active revision. For default selection, Active revisions with an Effective version take precedence. If none exists, the system selects the Pilot revision with an Effective version and the highest sequence. This allows a revision imported from a Center of Excellence or another Customer Environment to be qualified locally without replacing an existing Active revision with an Effective version as the default. For more information on the revision state model, see [[revisions-index#state-model]]. ## Mark Revision as Pilot To mark an Active revision as Pilot, open the versioned object and select **Mark Revision as Pilot** on the top ribbon. Optionally, enter a comment, and then select **Pilot** to complete the operation. !!! info Marking a revision as Pilot clears its Default From Date and Default To Date and recalculates the default revision. The Universal State of the revision and its versions remains unchanged. For more information, see [[user-guide-manage-default-revisions]]. ## Mark Revision as Active To mark a Pilot revision as Active, open the versioned object and select **Mark Revision as Active** on the top ribbon. Optionally, enter a comment, and then select **Active** to complete the operation. !!! info Marking a revision as Active recalculates the default revision without modifying the Universal State of the revision or its versions. It does not restore the default dates cleared when the revision was marked as Pilot. For more information, see [[user-guide-manage-default-revisions]].
