  The SAP error message CNV_10520018 indicates that there are different values found for the field FIKEY in the table DFKKSUM. This typically occurs during data migration or conversion processes, particularly when using SAP's data migration tools or during system upgrades.
  Cause:
  
  Data Inconsistency: The primary cause of this error is data inconsistency in the DFKKSUM table. This table is used for storing financial document summaries, and if there are multiple entries with the same key but different values, it can lead to this error.
  Duplicate Entries: There may be duplicate entries in the table for the same FIKEY, which should ideally be unique.
  Data Migration Issues: If data has been migrated from another system or during a system upgrade, inconsistencies may arise if the data was not properly validated or cleaned before migration.
  
  Solution:
  
  Data Analysis: Analyze the entries in the DFKKSUM table to identify the records that are causing the inconsistency. You can use SQL queries to find duplicates or different values for the same FIKEY.
  SELECT FIKEY, COUNT(*)
  FROM DFKKSUM
  GROUP BY FIKEY
  HAVING COUNT(*) > 1;
  
  Data Correction: Once you identify the problematic entries, you will need to correct the data. This may involve:
  
  Merging duplicate entries.
  Deleting incorrect entries.
  Updating values to ensure consistency.
  
  
  Data Validation: After making corrections, validate the data to ensure that there are no further inconsistencies. You can run checks to confirm that each FIKEY has a unique and correct value.
  Re-run Migration: If this error occurred during a migration process, you may need to re-run the migration after correcting the data issues.
