  The SAP error message CATSXT143, which states "The temporary key &1 is not unique," typically occurs in the context of the Cross-Application Time Sheet (CATS) module. This error indicates that there is a conflict with a temporary key that is being used to identify a time entry or record, and it is not unique within the system.
  Cause:
  
  Duplicate Temporary Keys: The most common cause of this error is that the temporary key being generated or used for a time entry already exists in the system. This can happen if multiple users are trying to create or modify time entries simultaneously, leading to a race condition.
  Session Issues: If a user has multiple sessions open and is trying to perform actions that involve the same temporary key, it can lead to conflicts.
  Data Consistency Issues: There may be inconsistencies in the database or temporary tables that are causing the system to generate non-unique keys.
  
  Solution:
  
  Refresh the Session: If you encounter this error, try refreshing your session or logging out and back into the SAP system. This can help clear any temporary data that may be causing the conflict.
  Check for Duplicates: Review the entries you are trying to create or modify to ensure that there are no duplicates. If you are working in a team, coordinate with your colleagues to avoid simultaneous entries.
  Use Unique Identifiers: If you are programmatically generating temporary keys, ensure that the logic used to create these keys guarantees uniqueness.
  Clear Temporary Data: If the issue persists, it may be necessary to clear temporary data or cache in the CATS module. This may require assistance from your SAP Basis or technical team.
