• What is the cause and solution for SAP error message CNV_10020062 - Conc./frag. objekt &1, table field &2: Offset/Length is too big ?

  The SAP error message CNV_10020062 typically occurs during data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools. This error indicates that there is an issue with the data being processed, specifically related to the offset and length of a field in a table.
  Cause:
  The error message "Conc./frag. objekt &1, table field &2: Offset/Length is too big" suggests that the data being processed has an offset or length that exceeds the defined limits for the corresponding field in the database table. This can happen due to several reasons:
  
  Data Type Mismatch: The source data may have a different data type or length than what is defined in the target table.
  Incorrect Mapping: During the data migration process, the mapping of fields may not be correctly defined, leading to an attempt to insert data that is too large for the target field.
  Corrupted Data: The source data may contain corrupted or malformed entries that exceed the expected size.
  Configuration Issues: There may be configuration settings in the migration tool that are not aligned with the data structure.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types and Lengths: Review the data types and lengths of the fields in both the source and target tables. Ensure that they match and that the source data does not exceed the limits of the target fields.
  
  
  Adjust Mapping: If you are using a data migration tool, check the mapping configuration to ensure that fields are correctly mapped and that any transformations applied do not result in oversized data.
  
  
  Data Cleansing: Inspect the source data for any entries that may be too large or malformed. Cleanse the data to ensure it adheres to the expected formats and sizes.
  
  
  Modify Target Table: If necessary, consider modifying the target table to accommodate larger data sizes, but be cautious as this may have implications for the overall database design and performance.
  
  
  Review Logs: Check the logs generated during the migration process for more detailed information about the specific records causing the error. This can help identify the problematic data.
  
  
  Testing: After making adjustments, perform a test migration with a smaller dataset to ensure that the changes resolve the issue before proceeding with the full migration.
