• What is the cause and solution for SAP error message CNV_PE140 - Interface types do not match ?

  The SAP error message CNV_PE140: Interface types do not match typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is a mismatch between the expected data types of the source and target fields in the interface.

  Solutions:
  
  Check Data Types: Review the data types of the source and target fields. Ensure that they are compatible. If necessary, modify the source data to match the expected target data types.
  Adjust Field Lengths: If the error is due to field length, consider truncating the source data or increasing the length of the target field if feasible.
  Review Mapping Configuration: Go through the mapping configuration in the migration tool to ensure that all fields are correctly mapped and that the data types align.
  Data Cleansing: Perform data cleansing on the source data to ensure that it adheres to the expected formats and types.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand the expected data formats and types.
