gathered in CNV_INDX_STRUC doesn't comply with the real RELID
structure.
This will trigger an error if this component is relevant for
conversion.

• What is the cause and solution for SAP error message CNV21500010 - Type of comp. &1 is different in CNV_INDX_STRUC(&2) than in directory(&3) ?

  The SAP error message CNV21500010 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 a mismatch in the data structure or type of a component between the source data and the target structure defined in the migration directory.
  Cause:
  The error message indicates that the type of a component (field) in the source structure (CNV_INDX_STRUC(&2)) does not match the type defined in the migration directory (&3). This can happen due to several reasons:
  
  Data Type Mismatch: The data type of a field in the source system is different from what is expected in the target system.
  Field Length Differences: The length of the field in the source system may not match the length defined in the target structure.
  Incorrect Mapping: The mapping configuration between the source and target structures may be incorrect or incomplete.

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Data Types: Verify the data types of the fields in both the source and target structures. Ensure that they match in terms of type (e.g., CHAR, NUMC, etc.) and length.
  
  
  Review Mapping Configuration: Go through the mapping configuration in the migration tool. Ensure that all fields are correctly mapped and that there are no discrepancies.
  
  
  Adjust Source Data: If the source data does not conform to the expected structure, you may need to adjust the data in the source system or transform it before migration.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be specific guidelines or requirements for the data structures involved.
