This error typically arises when you are trying to use effectivity parameters (like validity dates or conditions) with an OAN element type that does not support them.
  Cause:

  Solution:
  
  Check OAN Element Type: Verify the type of OAN element you are using. Ensure that it is one that supports effectivity parameters. You may need to consult the SAP documentation or your system administrator for the specific types that support effectivity.
  Review Configuration: Go through the configuration of your variant configuration model. Ensure that the OAN elements are set up correctly and that you are not trying to apply effectivity to an unsupported element.
  Modify Usage: If you find that the element type does not support effectivity, consider whether you can achieve your goal through a different approach, such as using a different element type that does support effectivity.
  Consult Documentation: Refer to SAP's official documentation or help resources for more detailed information on OAN element types and their capabilities regarding effectivity.
