Hi Wenyu , 

your expression needs to be corrected little 

Are you trying to compare between the object and the variable ?

If yes ,you did not used any object in the expression. 

Help me to understand your requirement , I can guide you through the right expression

  • Retrieve Lists:

    • Retrieve: ReservationList (List of Reservation)
    • Retrieve: TableList (List of Table)
  • Create Helper Entities:

    • Create: TableListHelper
    • Create: AvailableTableList (empty list of Table)
  • Loop Through TableList:

    • Loop: TableList
      • Loop Variable: CurrentTable
  • Inside Loop:

    • Decision: Check Availability
      • Expression:

        not(any($ReserveList[Table = $CurrentTable and StartTime <= $StartTime and EndTime >= $StartTime]))

  • True Path of Decision:

    • Add to List: AvailableTableList
      • Action: Add CurrentTable

    • Change Object: TableHelper
      • Association: $TableHelper/AvailableTables = $AvailableTableList
    • End: Return $TableHelper
