This error can arise in various contexts, such as during data migration, data extraction, or when running specific reports that involve complex data processing.
  Cause:
  
  Data Inconsistency: The error often indicates that there is a discrepancy between the results obtained from ABAP processing and those obtained from SQL queries. This can happen if the data in the database has been modified or if there are inconsistencies in the data model.
  Conversion Logic Issues: There may be issues in the logic used for converting data from ABAP to SQL or vice versa. This could be due to incorrect data types, missing fields, or incorrect handling of null values.
