  The SAP error message IWO_UI806 ("You cannot use old and new operation lists together") typically occurs in the context of work order management, particularly when dealing with operations in maintenance orders or production orders. This error indicates that there is a conflict between the operation lists being used in the order.
  Cause:
  The error arises when there is an attempt to combine or use both old and new operation lists in a single work order or operation. This can happen due to several reasons:
  
  Versioning Issues: The system may have different versions of operation lists, and the order is trying to reference both.
  Data Inconsistency: There may be inconsistencies in the data where some operations are from an older version while others are from a newer version.
  Configuration Settings: The system configuration may not allow mixing of operation lists from different versions.
  
  Solution:
  To resolve the IWO_UI806 error, you can take the following steps:

  Update Operations: If you find that some operations are from an old list and others from a new list, you may need to:
  
  Remove the old operations and replace them with the new ones.
  Alternatively, if the old operations are still needed, you may need to create a new work order that uses only the old operation list.
  
  
  
  Consistency Check: Run a consistency check on the work order to ensure that all data is aligned and there are no discrepancies.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's SAP support team for specific guidelines on handling operation lists and work orders.
