  Update Validity Dates: If necessary, update the validity dates to include the current date or the date you wish to perform the maintenance. This may require appropriate authorizations.
  Open Posting Period: Ensure that the posting period is open for the date you are trying to work with. You can check this in the financial settings or by consulting with your finance team.
  Consult with SAP Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting the SAP Help Portal for further assistance.
