• What is the cause and solution for SAP error message CNV_PE525 - Parameter &1 is not structured ?

  The SAP error message CNV_PE525, which states "Parameter &1 is not structured," typically occurs in the context of data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools. This error indicates that a parameter expected to be structured (i.e., a table or a complex data type) is not in the correct format.
  Cause:
  
  Incorrect Parameter Type: The parameter being passed to a function or method is not of the expected structured type. This could happen if a simple data type (like a string or integer) is passed instead of a structured type (like a table or a custom structure).
  Data Mapping Issues: During data migration, if the mapping of fields from the source to the target does not align correctly, it can lead to this error.
  Configuration Errors: Incorrect configuration settings in the migration tool or in the source/target systems can lead to this issue.
  Custom Code Issues: If there is custom code involved in the migration process, it may not be handling the parameters correctly.
  
  Solution:
  
  Check Parameter Types: Review the function or method where the error occurs and ensure that the parameters being passed are of the correct structured type. If necessary, modify the code to pass the correct type.
  Review Data Mapping: Ensure that the data mapping between the source and target systems is correctly defined. Check for any discrepancies in the data types and structures.
  Configuration Review: Go through the configuration settings of the migration tool to ensure that everything is set up correctly. This includes checking any transformation rules that may be applied.
  Debugging: If you have access to the code, use debugging tools to trace the execution and identify where the incorrect parameter is being passed.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand the expected parameter types and structures.
