• What is the cause and solution for SAP error message ECATT549 - When using REF in eCATT, only direct passes are used, not variants ?

  The SAP error message ECATT549 indicates that when using the eCATT (extended Computer Aided Test Tool) framework, there is an issue with the use of reference parameters (REF) in your test scripts. Specifically, the error states that only direct passes are used, and variants cannot be utilized in this context.
  Cause:
  The primary cause of this error is that eCATT does not support the use of variants when passing parameters by reference (REF). In eCATT, parameters can be passed either by value or by reference. When you attempt to use a variant (which is a predefined set of values) with a reference parameter, the system raises this error because it expects a direct value instead.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Change Parameter Passing Method: If possible, change the parameter passing method from REF to a direct value (by value). This way, you can use variants without encountering the error.
  
  
  Use Direct Values: Instead of using a variant, directly specify the values you want to pass to the REF parameter in your eCATT script.
  
  
  Review Test Script: Go through your eCATT test script and ensure that you are not trying to use variants with REF parameters. If you need to use variants, consider restructuring your test case to avoid using REF parameters.
  
  
  Consult Documentation: Refer to the official SAP documentation for eCATT to understand the limitations and best practices regarding parameter passing.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as newer versions may have improved functionality or additional features that could help mitigate this issue.
