• What is the cause and solution for SAP error message CNV20201095 - Field overflow with suffix rule was avoided!! e. g. for (&1,&2,&3) ?

  The SAP error message CNV20201095 indicates that there is a field overflow issue related to a suffix rule in a data conversion or migration process. This typically occurs when the data being processed exceeds the defined length of a field in the target structure, leading to potential data loss or truncation.
  Cause:
  
  Field Length Exceeded: The data being migrated or converted is longer than the maximum length defined for the target field.
  Suffix Rule Misconfiguration: The suffix rule applied may not be correctly configured to handle the data being processed, leading to an overflow.
  Data Quality Issues: The source data may contain unexpected characters or formats that increase the length of the data being processed.
  
  Solution:
  
  Check Field Lengths: Review the target field definitions in the data model to ensure they can accommodate the incoming data. If necessary, increase the field length in the target structure.
  Adjust Suffix Rules: Review and modify the suffix rules to ensure they are correctly configured to handle the data being processed. This may involve adjusting the logic or conditions under which suffixes are applied.
  Data Cleansing: Perform data cleansing on the source data to ensure it meets the expected format and length requirements before migration.
  Error Handling: Implement error handling mechanisms to log and manage instances where data overflows occur, allowing for manual review and correction.
  Testing: Conduct thorough testing of the migration process with various data sets to identify potential overflow issues before executing the full migration.
