• What is the cause and solution for SAP error message ECATT603 - Complex parameters can only be compared using '' ?

  The SAP error message ECATT603, which states "Complex parameters can only be compared using ''", typically occurs in the context of eCATT (extended Computer Aided Test Tool) when you are trying to compare complex parameters (like structures or tables) in a test script. This error indicates that the comparison operation you are attempting to perform is not valid for complex data types.
  Cause:
  
  Complex Data Types: The error arises when you attempt to use standard comparison operators (like =, <>, etc.) on complex parameters (structures, internal tables, etc.) instead of using the appropriate methods for comparison.
  Incorrect Syntax: The syntax used for comparison may not be suitable for the type of data being compared.
  
  Solution:
  
  
  Use the Correct Comparison Method: For complex parameters, you should use the appropriate eCATT functions or methods designed for comparing complex data types. This often involves using specific eCATT commands or functions that can handle the structure of the data.
  For example, you might need to use:
  
  COMPARE command for comparing structures.
  CHECK command for validating the contents of internal tables.
  
  
  
  Review the Test Script: Go through your eCATT script and ensure that you are not trying to directly compare complex parameters using standard comparison operators. Instead, utilize the provided eCATT functions that are designed for this purpose.
  
  
  Check Documentation: Refer to the SAP eCATT documentation for detailed information on how to handle complex parameters and the specific functions available for comparison.
  
  
  Related Information:
  
  eCATT Documentation: SAP provides extensive documentation on eCATT, which includes examples and guidelines on how to work with complex parameters.
