Symptoms

Assume that you run the planning engine for an item with a demand included in Microsoft Dynamics NAV 2009. You run the planning engine for the item again. In this situation, if the demand is not included in the second time running, duplicate reservation entries are generated. 
Note This problem occurs whether the locations use the warehouse functionality or not.
This problem occurs in the following products:

  • Microsoft Dynamics NAV 2009 R2

  • Microsoft Dynamics NAV 2009 Service Pack 1 (SP1)

Code changes

Note Always test code fixes in a controlled environment before you apply the fixes to your production computers.
To resolve this problem, follow these steps:

  1. Change the code in the CloseReservEntry function in the Reservation Engine Mgt. codeunit (99000831) as follows: 
    Existing code

    ...
    ReservEntry2.MODIFY;
    ReservEntry2."Quantity (Base)" :=
    ReservMgt.MatchSurplus(ReservEntry2,SurplusReservEntry,ReservEntry2."Quantity (Base)",NOT ReservEntry2.Positive,
    AvailabilityDate,Item."Order Tracking Policy");
    IF ReservEntry2."Quantity (Base)" = 0 THEN BEGIN
    ReservEntry2.DELETE(TRUE);
    END ELSE BEGIN
    ReservEntry2.MODIFY;

    IF Item."Order Tracking Policy" = Item."Order Tracking Policy"::"Tracking & Action Msg." THEN BEGIN
    ModifyActionMessageDating(ReservEntry2);
    IF DeleteAll THEN
    ReservMgt.IssueActionMessage(ReservEntry2,FALSE,ReservEntry)
    ELSE
    ...

    Replacement code

    ...
    ReservEntry2.MODIFY;
    ReservEntry2."Quantity (Base)" :=
    ReservMgt.MatchSurplus(ReservEntry2,SurplusReservEntry,ReservEntry2."Quantity (Base)",NOT ReservEntry2.Positive,
    AvailabilityDate,Item."Order Tracking Policy");
    IF ReservEntry2."Quantity (Base)" = 0 THEN BEGIN
    ReservEntry2.DELETE(TRUE);
    END ELSE BEGIN

    // Add the following line.
    ReservEntry2.VALIDATE("Quantity (Base)");

    ReservEntry2.MODIFY;

    IF Item."Order Tracking Policy" = Item."Order Tracking Policy"::"Tracking & Action Msg." THEN BEGIN
    ModifyActionMessageDating(ReservEntry2);
    IF DeleteAll THEN
    ReservMgt.IssueActionMessage(ReservEntry2,FALSE,ReservEntry)
    ELSE
    ...
  2. Add a new key in the Inventory Profile table (99000853) as follows:

    { ;Source Type,Source Order Status,Source ID,Source Batch Name,Source Ref. No.,Source Prod. Order Line,IsSupply,Due Date }
  3. Add a new local parameter in the DeleteTracking function in the Inventory Profile Offsetting codeunit (99000854) as follows:
    Existing code

    LOCAL PROCEDURE DeleteTracking@25(VAR SKU@1000 : Record 5700;ToDate@1001 : Date);

    Replacement code

    LOCAL PROCEDURE DeleteTracking@25(VAR SKU@1000 : Record 5700;ToDate@1001 : Date;VAR SupplyInventoryProfile@1002 : Record 99000853);
  4. Add a new local variable in the DeleteTracking function in the Inventory Profile Offsetting codeunit (99000854), and then specify the variable as follows:

    • Name: ResEntryWasDelete

    • DataType: Boolean

  5. Change the code in the DeleteTracking function in the Inventory Profile Offsetting codeunit (99000854) as follows:
    Existing code

    ...
    IF FIND('-') THEN
    REPEAT
    IF (("Reservation Status" <> "Reservation Status"::Reservation) AND
    ("Expected Receipt Date" <= ToDate) AND
    ("Shipment Date" <= ToDate)) OR
    ((Binding = Binding::"Order-to-Order") AND ("Shipment Date" <= ToDate))
    THEN BEGIN

    // Delete the following lines.
    ActionMsgEntry.SETRANGE("Reservation Entry","Entry No.");
    DELETE;
    ActionMsgEntry.DELETEALL;
    END;
    // End of the lines.

    UNTIL NEXT = 0;
    END;
    ...

    Replacement code

    ...
    IF FIND('-') THEN
    REPEAT
    IF (("Reservation Status" <> "Reservation Status"::Reservation) AND
    ("Expected Receipt Date" <= ToDate) AND
    ("Shipment Date" <= ToDate)) OR
    ((Binding = Binding::"Order-to-Order") AND ("Shipment Date" <= ToDate))
    THEN BEGIN

    // Add the following lines.
    ResEntryWasDeleted := TRUE;
    DELETE;
    END ELSE
    ResEntryWasDeleted := CloseTracking(ReservEntry,SupplyInventoryProfile,ToDate);

    IF ResEntryWasDeleted THEN BEGIN
    ActionMsgEntry.SETRANGE("Reservation Entry","Entry No.");
    ActionMsgEntry.DELETEALL;
    END;
    // End of the lines.

    UNTIL NEXT = 0;
    END;
    ...
  6. Add a new CloseTracking function in the Inventory Profile Offsetting codeunit (99000854) as follows:

    LOCAL PROCEDURE CloseTracking@92(ReservEntry@1000 : Record 337;VAR SupplyInventoryProfile@1001 : Record 99000853;ToDate@1002 : Date) : Boolean;
    VAR
    xSupplyInventoryProfile@1003 : Record 99000853;
    ReservationEngineMgt@1004 : Codeunit 99000831;
    Closed@1005 : Boolean;


    WITH ReservEntry DO BEGIN
    IF "Reservation Status" <> "Reservation Status"::Tracking THEN
    EXIT(FALSE);

    xSupplyInventoryProfile.COPY(SupplyInventoryProfile);
    Closed := FALSE;

    IF ("Expected Receipt Date" <= ToDate) AND
    ("Shipment Date" > ToDate)
    THEN BEGIN
    // tracking exists with demand in future
    SupplyInventoryProfile.SETCURRENTKEY(
    "Source Type","Source Order Status","Source ID","Source Batch Name","Source Ref. No.","Source Prod. Order Line",IsSupply);
    SupplyInventoryProfile.SETRANGE("Source Type","Source Type");
    SupplyInventoryProfile.SETRANGE("Source Order Status","Source Subtype");
    SupplyInventoryProfile.SETRANGE("Source ID","Source ID");
    SupplyInventoryProfile.SETRANGE("Source Batch Name","Source Batch Name");
    SupplyInventoryProfile.SETRANGE("Source Ref. No.","Source Ref. No.");
    SupplyInventoryProfile.SETRANGE("Source Prod. Order Line","Source Prod. Order Line");
    SupplyInventoryProfile.SETRANGE("Due Date",0D,ToDate);

    IF NOT SupplyInventoryProfile.ISEMPTY THEN BEGIN
    // demand is either deleted as well or will get Surplus status
    ReservMgt.CloseReservEntry(ReservEntry,FALSE,FALSE);
    Closed := TRUE;
    END;
    END;
    END;

    SupplyInventoryProfile.COPY(xSupplyInventoryProfile);
    EXIT(Closed);
  7. Change the code in the PlanItem function in the Inventory Profile Offsetting codeunit (99000854) as follows:
    Existing code

    ...
    // Preliminary clean of tracking
    IF DemandExists OR SupplyExists THEN

    // Delete the following line.
    DeleteTracking(TempSKU,ToDate);

    MatchAttributes(Supply,Demand);

    // Calculate initial inventory
    ...

    Replacement code

    ...
    // Preliminary clean of tracking
    IF DemandExists OR SupplyExists THEN

    // Add the following line.
    DeleteTracking(TempSKU,ToDate,Supply);

    MatchAttributes(Supply,Demand);

    // Calculate initial inventory
    ...
