  Review Changes: Carefully review the changes you are trying to make to the expression. Ensure that they are compatible with the existing data model and do not conflict with other measures or dimensions.
  Check Dependencies: Identify any dependencies that the expression has on other elements in the model. You may need to adjust those dependencies or remove them before making changes.
