  Causes:
  
  Variable Changes: The variables used in the query have been modified, which can include changes in their default values, selection options, or dependencies.
  Data Model Changes: Changes in the InfoObjects, InfoProviders, or the underlying data model can lead to inconsistencies in the expected variable values.

  Data Model Validation: Validate the underlying data model to ensure that there are no inconsistencies or issues with the InfoObjects or InfoProviders that could affect the variables.
  User Training: If the issue is related to user input, consider providing training or documentation to users on how to correctly input variable values.
