Record.FilterGroup(-1) on FlowFIelds

[Arthurvdv]

It seems that Cross-column (Number -1) is not supported on FlowFields, see the example below.

procedure MyProcedure()
var
    Item: Record Item;
begin
    Item.FilterGroup(-1);
    Item.SetFilter(Inventory, '<>%1', 0);
    Item.SetFilter("Safety Stock Quantity", '<>%1', 0);
    Item.FilterGroup(0);
    if Item.FindSet() then
        repeat
            ...
        until Item.Next() = 0;
end;
