  Check Confirmation Dates: Verify the confirmation date you are trying to use. Ensure that it falls within the validity period of the supersession chain for the material.
  
  
  Review Supersession Chain: Go to the material master data and check the supersession chain. Ensure that the materials and their validity periods are correctly defined.

  Update Material Master: If the validity period of the supersession chain needs to be extended or modified, you may need to update the material master data to reflect the correct dates.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's guidelines on handling supersession chains and confirmation processes.
