The SAGE Budget and eGC1 Shared Access Data user guide article explains who has access to the items.
If you have access, then provided the eGC1 is connected to a budget in SAGE and is already in routing, you can withdraw it. From within SAGE Budget, go to the Budget History tab, and click the eGC1 History & Comments link to view the Approvals History. (Note: The Approvals History is only available after an eGC1 is in Routing status.) From the Approvals History, click the Withdraw eGC1 link.
Note: If an eGC1 is marked “Yes” for Ready to Submit and has In OSP status, it cannot be withdrawn. Instead, contact OSP and request they return the eGC1.
