[Public procedure] Query "Qty. Reserved From Item Ledger" - SetSourceFilter

[fvet]

Describe the request

Can you please expose function SetSourceFilter in Query "Qty. Reserved From Item Ledger"?

Additional context

We want to calculate the ReservedQtyFromInventory for a given Sales / Purchase order by location, forcing us to copy the functions from codeunit 99000832 "Sales Line-Reserve" GetReservedQtyFromInventory.

Doing so fails to compile due to the missing access to SetSourceFilter.

internal procedure GetReservedQtyFromInventoryWithLocation(SalesHeader: Record "Sales Header"; LocationCode: Code[10]): Decimal
    var
        ReservationEntry: Record "Reservation Entry";
        QtyReservedFromItemLedger: Query "Qty. Reserved From Item Ledger";
    begin
        ReservationEntry.SetSource(Database::"Sales Line", SalesHeader."Document Type".AsInteger(), SalesHeader."No.", 0, '', 0);
        QtyReservedFromItemLedger.SetSourceFilter(ReservationEntry); // MISSING     
        QtyReservedFromItemLedger.SetFilter(Location_Code, LocationCode);
        QtyReservedFromItemLedger.Open();
        if QtyReservedFromItemLedger.Read() then
            exit(QtyReservedFromItemLedger.Quantity__Base_);

        exit(0);
    end;
