• What is the cause and solution for SAP error message CNV_PE404 - Move-corresponding data types are not identical ?

  The SAP error message CNV_PE404 indicates that there is a mismatch in the data types when using the MOVE-CORRESPONDING statement in ABAP. This error typically occurs during data migration or conversion processes, particularly when using the SAP Conversion Tools or during custom ABAP programs that involve data manipulation.
  Cause:
  The error arises when the source and target structures (or internal tables) involved in the MOVE-CORRESPONDING statement have fields with different data types or incompatible structures. This can happen due to:
  
  Different Data Types: The fields in the source and target structures may have different data types (e.g., one is a character type and the other is a numeric type).
  Field Length Mismatch: The lengths of the fields may differ, which can lead to truncation or overflow issues.
  Incompatible Structures: The structures may not be compatible due to differences in field names, types, or lengths.
  
  Solution:
  To resolve the CNV_PE404 error, you can take the following steps:
  
  
  Check Data Types: Verify that the data types of the corresponding fields in both the source and target structures are identical. You can do this by checking the Data Dictionary (SE11) for the structures involved.
  
  
  Adjust Field Lengths: Ensure that the lengths of the fields match. If necessary, adjust the lengths in the target structure to accommodate the source data.
  
  
  Modify the Code: If the structures cannot be made identical, consider modifying the code to handle the differences explicitly. For example, you can use individual field assignments instead of MOVE-CORRESPONDING to control the data transfer more precisely.
  
  
  Use Type Casting: If the data types are different but can be converted, consider using type casting or conversion functions to ensure compatibility.
  
  
  Debugging: Use the ABAP debugger to step through the code and identify the exact point of failure. This can help you understand which fields are causing the issue.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific conversion or migration process you are working on, as there may be known issues or recommendations.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for details on the MOVE-CORRESPONDING statement and data type compatibility.
  SAP Notes: Check for relevant SAP Notes that may address this specific error or provide guidance on data migration issues.
  Community Forums: Engage with the SAP community through forums like SAP Community or Stack Overflow, where you can find discussions related to similar issues.
  
  By following these steps, you should be able to identify and resolve the cause of the CNV_PE404 error in your SAP environment.
