• What is the cause and solution for SAP error message ECATT418 - The interface type (&1) does not correspond to required type (&2) ?

  The SAP error message ECATT418 indicates a mismatch between the expected interface type and the actual interface type being used in an eCATT (extended Computer Aided Test Tool) script. This error typically arises when the script is trying to use a function module or method that does not match the expected parameters or interface type defined in the eCATT configuration.
  Cause:
  
  Mismatch in Interface Types: The interface type specified in the eCATT script does not match the required interface type of the function module or method being called.
  Incorrect Parameter Mapping: The parameters being passed to the function module or method do not align with what is expected, either in terms of data types or structure.
  Changes in Function Module: If the function module or method has been modified (e.g., parameters added or removed), the eCATT script may not have been updated accordingly.
  
  Solution:
  
  Check Interface Definition: Verify the interface type of the function module or method you are trying to call. You can do this by checking the function module in transaction SE37 or the method in transaction SE80.
  Update eCATT Script: Modify the eCATT script to ensure that the interface type and parameters match the expected definitions. This may involve:
  
  Adjusting the parameter types in the eCATT script.
  Ensuring that all required parameters are being passed.
  Removing any unnecessary parameters that are not part of the function module's interface.
  
  
  Test the Function Module: Before running the eCATT script, test the function module or method independently to ensure it works as expected with the parameters you intend to use.
  Consult Documentation: If there are changes in the function module or method, refer to the relevant documentation or change logs to understand what modifications have been made.
  
  Related Information:
  
  eCATT Documentation: Familiarize yourself with the eCATT documentation available in SAP Help Portal for best practices and guidelines on creating and maintaining eCATT scripts.
