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. Create a local function UpdateRelatedComponent in the codeunit (99000809):

   ...
   LOCAL PROCEDURE UpdateRelatedComponent@15(ParentReqLine@1000 : Record 246);
   WITH PlanningComponent DO BEGIN
   SETCURRENTKEY("Worksheet Template Name","Worksheet Batch Name","Worksheet Line No.","Item No.");
   SETRANGE("Worksheet Line No.",ParentReqLine."Line No.");
   SETFILTER("Item No.",'<>%1','');
   SETFILTER("Expected Quantity",'<>0');
   SETFILTER("Planning Level Code",'<>0');
   IF FIND('-') THEN
   REPEAT
   IF LineHasBeenCreated(ChildReqLine,PlanningComponent) THEN BEGIN
   UpdateRelatedComponent(ChildReqLine);
   IF ChildReqLine.Quantity <> "Expected Quantity" THEN BEGIN
   // qty has to be updated, there is a new need of component
   ChildReqLine.BlockDynamicTracking(Blocked);
   ChildReqLine.VALIDATE(Quantity,ChildReqLine.Quantity - "Expected Quantity");
   ChildReqLine.MODIFY;
   
   // updating qty of component for parent
   VALIDATE("Quantity per","Quantity per");
   MODIFY;
   END ELSE
   // line will be recreated
   ChildReqLine.DELETE(TRUE);
   END;
   UNTIL NEXT = 0;
   END;
   ...

   
   Add the following parameters in the function:

   • Name: PlanningComponent; DataType: Record (99000829)

   • Name: ChildReqLine; DataType: Record (246)

2. Create a local function LineHasBeenCreated in the codeunit (99000829):

   ...
   LOCAL PROCEDURE LineHasBeenCreated@18(VAR ChildReqLine@1000 : Record 246;PlanningComponent@1001 : Record 99000829) : Boolean;
   WITH ChildReqLine DO BEGIN
   SETCURRENTKEY("Worksheet Template Name","Journal Batch Name",Type,"No.");
   SETRANGE("Worksheet Template Name",PlanningComponent."Worksheet Template Name");
   SETRANGE("Journal Batch Name",PlanningComponent."Worksheet Batch Name");
   SETRANGE(Type,Type::Item);
   SETRANGE("No.",PlanningComponent."Item No.");
   SETRANGE("Variant Code",PlanningComponent."Variant Code");
   SETRANGE("Ref. Order Type","Ref. Order Type"::"Prod. Order");
   SETRANGE("Ref. Order Status",PlanningComponent."Ref. Order Status");
   SETRANGE("Ref. Order No.",PlanningComponent."Ref. Order No.");
   SETFILTER("Planning Level",'>%1',0);
   EXIT(FINDFIRST);
   END;
   ...

3. Change the code in the InsertPlanningLine function the codeunit (99000809) as follows:
   Existing code

   ...
    IF ReqLine2."Planning Level" < ReqLine."Planning Level" THEN
   ReqLine2."Planning Level" := ReqLine."Planning Level";
   
   ReqLine2.MODIFY; 
   ...

   Replacement code

   ...
    IF ReqLine2."Planning Level" <ReqLine."Planning Level" THEN
   ReqLine2."Planning Level" := ReqLine."Planning Level";
   
   // the ReqLine2 can have children which has to be delete or updated
   // Add the following line.
   UpdateRelatedComponent(ReqLine2);
   
   ReqLine2.MODIFY;  
   ...
