  Review Variable Definition: Check the definition of the variable in the SAP BW/BI system. Ensure that you are not trying to change properties that are restricted for DDIC types.
  Create a New Variable: If you need a variable with different properties, consider creating a new variable instead of modifying the existing one. This new variable can be defined with the desired attributes.
  Use Existing Variables: If the existing variable meets your requirements, use it as is without attempting to change its properties.
