  The SAP error message FE121 ("Entry & already exists. You cannot save your current entry.") typically occurs when you are trying to create or save a record in the system that already exists. This can happen in various contexts, such as when entering data in master records, transaction records, or configuration settings.
  Cause:
  
  
  Duplicate Entry: The most common cause is that the entry you are trying to save already exists in the database. This could be due to:
  
  Manual entry of the same data.
  Data imported from another system that contains duplicates.
  A previous save operation that was not completed successfully.
  
  
  
  Unique Constraints: The system has unique constraints on certain fields, meaning that no two records can have the same value for those fields.

  Solution:

  Using the search or filter functionality in the relevant transaction.

  Modify the Entry: If the entry already exists and you need to create a new one, modify the data you are trying to save to ensure it is unique. This may involve changing key fields or adding additional identifiers.
  
  
  Delete or Update Existing Records: If the existing entry is no longer needed, you may consider deleting it or updating it instead of creating a new one.
  
  
  Consult Documentation: Check the SAP documentation or help files for the specific transaction or module you are working with to understand the unique constraints and how to handle them.
