With BC we can create item variants and define different production BOMs at stockkeeping level.

But the calculation of the items low level code doesn't consider these BOMs.

So if a I have a component that is used on in one of these BOMs his low level code is 0.

If I take a look in codeunit 3687 "Low-Level Code Calculator" I see:

local procedure PopulateBOMTree(BOMStructure: Codeunit "BOM Tree")

  begin

    // Set nodes on the tree

    PopulateFromItemAndRelatedBOMs(BOMStructure);

    PopulateFromProductionBOMAndLines(BOMStructure);

    PopulateFromBOMComponents(BOMStructure);

  end;

These type of BOMs aren't considered in the low level code calculation.

If I take a look to the SKU table i see:

        field(99000751; "Production BOM No."; Code[20])

        {

            Caption = 'Production BOM No.';

            DataClassification = CustomerContent;

            TableRelation = "Production BOM Header";

            trigger OnValidate()

            var

                Item: Record Item;

                ItemUnitOfMeasure: Record "Item Unit of Measure";

                MfgSetup: Record "Manufacturing Setup";

                ProdBOMHeader: Record "Production BOM Header";

                CalculateLowLevelCode: Codeunit "Calculate Low-Level Code";

            begin

                if ("Production BOM No." <> '') and ("Production BOM No." <> xRec."Production BOM No.") then begin

                    ProdBOMHeader.Get("Production BOM No.");

                    ItemUnitOfMeasure.Get("Item No.", ProdBOMHeader."Unit of Measure Code");

                    if ProdBOMHeader.Status = ProdBOMHeader.Status::Certified then begin

                        MfgSetup.Get();

                        Item.Get("Item No.");

                        if MfgSetup."Dynamic Low-Level Code" then begin

                            Item."Low-Level Code" := CalculateLowLevelCode.CalcLevels(1, Item."No.", 0, 0);

                            CalculateLowLevelCode.SetRecursiveLevelsOnBOM(ProdBOMHeader, Item."Low-Level Code" + 1, false);

                        end;

                    end;

                end;

            end;

        }

This trigger calculates the right low level code for the components, but only if the dynamic low level code calculation is active.

can we extend the low level code calculation to these BOMs?
