The planning results are illogical when you run the "Calculate Regenerative Plan" function on a planning worksheet if you use safety stock in Microsoft Dynamics NAV 2009 SP1

This article applies to Microsoft Dynamics NAV for all countries and all language locales.
If you use safety stock for an item, when you run the Calculate Regenerative Plan function on a planning worksheet for the item in Microsoft Dynamics NAV 2009 Service Pack 1 (SP1), the planning results can be illogical. Sometimes, the planning engine plans multiple lines that do not correspond to the reorder cycle settings.

Code changes

Note Always test code fixes in a controlled environment before you apply the fixes to your production computers.

To install this hotfix, change the code in the CopyProdLines function in the Copy Production Order Document codeunit (99000854) as follows:
  1. Create a new function "ShallSupplyBeClosed". To do this, follow these steps:
    1. Add a local variable as follows:
      CloseSupply@1003 : Boolean;
    2. Add the code for the ShallSupplyBeClosed function. The code of created function is as follows:
      ShallSupplyBeClosed@89(SupplyInventoryProfile@1000 : Record 99000853;DemandDueDate@1001 : Date;IsReorderPointPlanning@1002 : Boolean) : Boolean;IF SupplyInventoryProfile."Is Exception Order" THEN BEGIN  IF TempSKU."Reordering Policy" = TempSKU."Reordering Policy"::"Lot-for-Lot" THEN    // Supply within Reorder Cycle will be summed up with exception order.    CloseSupply := CALCDATE(TempSKU."Reorder Cycle",SupplyInventoryProfile."Due Date") <DemandDueDate  ELSE    // Only demand in the same day as the exception will be summed up.    CloseSupply := SupplyInventoryProfile."Due Date" <> DemandDueDate;END ELSE  CloseSupply := IsReorderPointPlanning;EXIT(CloseSupply);
  2. Change the code of the PlanItem function as follows:
    Existing code
     ...         NextState::MatchQty:            BEGIN              IF Supply."Untracked Quantity" < Demand."Untracked Quantity" THEN BEGIN// Delete the following lines.                IF (Supply."Is Exception Order" AND (Supply."Due Date" <> Demand."Due Date")) OR                    (IsReorderPointPlanning AND NOT Supply."Is Exception Order")                THEN// The end of the deleted lines.                  NextState := NextState::CloseSupply                ELSE...
    Replacement code
    ...          NextState::MatchQty:            BEGIN              IF Supply."Untracked Quantity" < Demand."Untracked Quantity" THEN BEGIN// Add the following line.                IF ShallSupplyBeClosed(Supply,Demand."Due Date",IsReorderPointPlanning) THEN                  NextState := NextState::CloseSupply                ELSE...
