  The SAP error message WU091 ("No items were able to be assigned to the module") typically occurs in the context of SAP's Warehouse Management (WM) or Extended Warehouse Management (EWM) modules. This error indicates that the system was unable to find any items that could be assigned to a specific module or process, such as a transfer order, picking, or putaway.
  Causes:
