DPR_CATS026 - Details

• The SAP error message DPR_CATS026 indicates that a time entry (or confirmation) has already been confirmed in the Cross-Application Time Sheet (CATS) and cannot be deleted. This typically occurs when you attempt to delete a time entry that has already been processed or confirmed in the system.
  
  Cause:
  
  Confirmation Status: The time entry you are trying to delete has already been confirmed, meaning it has been processed and recorded in the system.
  Data Integrity: SAP enforces data integrity rules to prevent the deletion of confirmed entries, as this could lead to inconsistencies in reporting and time tracking.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to delete confirmed entries.
  
  
  Solution:
  
  
  Unconfirm the Entry: If you need to delete the entry, you may first need to unconfirm it. This can typically be done through the CATS transaction (CAT2 or CAT3) or through the relevant project management or time management transactions, depending on your configuration.
