  Review Confirmation Entries: If you need to make changes to the confirmation, you may need to reverse the existing confirmation (if applicable) or create a new order if the current one cannot be modified.
  Use the Correct Transaction: Ensure that you are using the correct transaction code for confirming orders. For example, use CO11N for single confirmations or CO15 for collective confirmations, depending on your needs.
  Consult Documentation: Review SAP documentation or help resources for guidance on the confirmation process and any specific configurations that may apply to your organization.
