You may first want to let OSP know you intend to make changes to your eGC1. Withdraw your eGC1 by clicking the Withdraw button on the Certify & Route page. After you make your changes, send your eGC1 back to OSP by clicking on the Complete button on the Certify & Route page. If you change the PI, the Organization Receiving Funding, or a response to a compliance question, the Approval Graph may change.
