CFD_REGISTRY_CHECK520 - Details

• The SAP error message CFD_REGISTRY_CHECK520 typically indicates a mismatch between the line type of a parameter in a BAdI (Business Add-In) implementation and the expected line type of a parameter in the BAdI definition. This error often arises during the registration or execution of a BAdI implementation when the data types or structures do not align as expected.
  
  Cause:
  
  Parameter Mismatch: The line type of the parameter RT_ADDITIONAL_DATA in your BAdI implementation does not match the expected line type defined in the BAdI interface.
  Incorrect Data Structure: The data structure or type used in the implementation may not conform to the expected structure defined in the BAdI.
  Changes in BAdI Definition: If the BAdI definition has been changed (e.g., new fields added or types modified), and the implementation has not been updated accordingly, this error can occur.
  
  
  Solution:
  
  Check BAdI Definition: Review the BAdI definition to understand the expected structure and types of the parameters. You
