  Remove Existing Assignment: If you need to assign the object to a new object set, you must first remove it from the current object set. This can usually be done through the object set management transaction.
  Reassign the Object: After removing the object from its current set, you can then proceed to assign it to the desired object set.
  Consult Documentation: If you are unsure about the process, refer to the SAP documentation or help resources related to object sets in PLM for detailed instructions.
