This error indicates that there is an open Warehouse Task (WT) associated with a Handling Unit (HU), but the WT is classified as a product WT, which may not be appropriate for the operation you are trying to perform.
  Cause:
  
  Open Warehouse Task: There is an existing open Warehouse Task for the Handling Unit that is preventing further processing.
  Product WT: The Warehouse Task is categorized as a product WT, which may not be suitable for the action you are attempting (e.g., picking, putaway, etc.).

  If the task is valid and should remain open, ensure that it is processed correctly.
  
  
  
  Review Task Type:
