local procedure onPrintLabel_OnAfterPopulateDataset(_TemplateName: Text[50]; var _RequestValues: Record "MOB NS Request Element"; _SourceRecRef: RecordRef; var _Dataset: Record "MOB Common Element")

var

// Making sure we only handle our own Label-Template
        if _TemplateName <> 'My custom Label-Template' then
            exit;

        // Read the Item No. from Dataset and change it
        // Item No. could have been collected or transferred from "context"/source table, where the print action was selected by the user
        if _Dataset.GetValue('ItemNumber') = 'ItemA' then

var

Item: Record Item;

BinContent: Record "Bin Content";

begin

// Item labels are always called with an Item. Else exit

if not Item.Get(_Dataset.GetValue('ItemNumber')) then

exit;

BinContent.SetRange("Location Code", _RequestValues.Get_Location());

BinContent.SetRange("Item No.", Item."No.");

BinContent.SetRange(Default, true);

if BinContent.FindFirst() then begin

local procedure onPrintLabel_OnAfterPopulateDataset(_TemplateName: Text[50]; var _RequestValues: Record "MOB NS Request Element"; _SourceRecRef: RecordRef; var _Dataset: Record "MOB Common Element")

var
        Item: Record Item;
        Vendor: Record Vendor;

        // If source is "Item" = Get record from RecordRef
        if _SourceRecRef.Number = database::Item then
            _SourceRecRef.SetTable(Item);

        // Set extrainfo fields and their labels in the Dataset
        _Dataset.SetValue('ExtraInfo01_Label', 'Desc.');
        _Dataset.SetValue('ExtraInfo01', Item.Description);

        _Dataset.SetValue('ExtraInfo02_Label', 'GTIN');
        _Dataset.SetValue('ExtraInfo02', Item.GTIN);

        _Dataset.SetValue('ExtraInfo03_Label', 'Purchasing Unit');
        _Dataset.SetValue('ExtraInfo03', Item."Purch. Unit of Measure");

        _Dataset.SetValue('ExtraInfo04_Label', 'Vendor');
        if Vendor.Get(item."Vendor No.") then
            _Dataset.SetValue('ExtraInfo04', Vendor.Name);

        // Additional custom values can also be used on the label
