For existing protocols, the CTMS team will populate the Grant Worktag before the integration goes live. After go-live, the study staff will be responsible for updating this in the Internal Account Number field in the PC Console Management tab if there are changes to their Grant Worktag. If a Grant Worktag has not been assigned to your study at intake, you can use other applicable budget numbers or Worktags that your team is using for startup costs, but you must return to this field to update before RG activation and OTA to ensure you have the correct Grant Worktag to enable the sponsor invoicing functionality.
