• What is the cause and solution for SAP error message ECATT_GUI_EN016 - Invalid parameter combination ?

  The SAP error message ECATT_GUI_EN016: Invalid parameter combination typically occurs in the context of eCATT (extended Computer Aided Test Tool) when there is an issue with the parameters being passed to a test script or when the configuration of the test script is incorrect.
  Causes:
  
  
  Incorrect Parameter Values: The parameters provided to the eCATT script may not match the expected values or formats. This can happen if the parameters are not defined correctly in the test script or if the data being passed is invalid.
  
  
  Missing Parameters: Required parameters may be missing from the test script execution, leading to an invalid combination of parameters.
  
  
  Incompatible Parameter Types: The types of parameters being passed may not be compatible with what the eCATT script expects (e.g., passing a string where a number is expected).
  
  
  Configuration Issues: There may be issues with the configuration of the eCATT test script or the test data being used.
  
  
  Version Mismatch: If there are different versions of the eCATT tool or the SAP system components, it may lead to compatibility issues.

  Debugging: Use the debugging features of eCATT to step through the script and identify where the invalid parameter combination is occurring. This can help pinpoint the exact issue.
  
  
  Consult Documentation: Refer to the SAP documentation for eCATT to understand the expected parameter combinations and any constraints that may apply.
