This error typically arises when the system encounters multiple entries that should be unique based on the defined key fields.
  Cause:
  
  Data Integrity Issues: The most common cause of this error is that there are duplicate entries in the database table that the optimizer is trying to access. This can happen due to incorrect data uploads, manual data entry errors, or issues during data replication from other systems.
  Configuration Errors: Sometimes, the configuration settings for the optimizer or the planning area may not be set up correctly, leading to conflicts in the data.
  Custom Developments: If there are custom programs or enhancements that manipulate the data in the relevant tables, they may inadvertently create duplicates.

  Deleting the duplicate entries if they are not needed.
