• What is the cause and solution for SAP error message FAGL_SKF021 - Duplicate entry of an identical line with key figure &1 not permitted ?

  The SAP error message FAGL_SKF021 indicates that there is a duplicate entry of an identical line with a specific key figure in the context of Financial Accounting (FI) or Controlling (CO) modules, particularly when dealing with line items in a report or during data entry. This error typically arises when the system detects that the same key figure is being entered multiple times in a way that violates the uniqueness constraints defined in the system.
  Cause:
  
  Duplicate Data Entry: The most common cause is that the same key figure is being entered more than once for the same period, account, or other relevant dimensions.
  Data Upload Issues: If data is being uploaded from an external source (like a flat file or another system), it may contain duplicate records.
  Configuration Issues: There may be configuration settings in the system that enforce uniqueness for certain key figures, leading to this error when duplicates are detected.
  
  Solution:
  
  Check for Duplicates: Review the data being entered or uploaded to ensure that there are no duplicate entries for the same key figure. This can often be done by filtering or sorting the data to identify duplicates.
  Data Correction: If duplicates are found, correct the data by removing or consolidating the duplicate entries before attempting to save or upload again.
  Review Upload Process: If the error occurs during a data upload, check the source data for duplicates and ensure that the upload process includes checks for uniqueness.
  Adjust Configuration: If necessary, review the configuration settings related to the key figures in question. If the uniqueness constraint is too strict for your business process, consider adjusting it, but be cautious as this may have broader implications.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to the key figure in question, as there may be additional context or considerations based on your specific implementation.
  
  Related Information:
  
  Transaction Codes: You may want to check transactions like FAGLB03 (Display G/L Account Line Items) or FAGLB04 (Display G/L Account Balances) to analyze the data.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  User Exits or BAdIs: If you have custom logic implemented, check if any user exits or BAdIs are affecting the data entry process.
  Testing: After making corrections, test the process in a development or quality assurance environment before applying changes to production.
  
  By following these steps, you should be able to identify the cause of the FAGL_SKF021 error and implement a solution to resolve it.
