Run Print Labels and Print Shipment Confirmation from one button

​@jacobslotta06 

The main issue here is that both PrintPackageFiles and printShipmentConfirmation.Press() are trying to trigger file downloads or reports in the same request cycle, and Acumatica doesn’t allow multiple file streams to be returned in a single HTTP response.

What ends up happening is the first action executes, but the second one is silently skipped or suppressed, especially if it also tries to return a file or launch the report viewer.

To work around this, you can split the two actions into separate long operations. Here's how you can adjust your code:

public PXAction<SOShipment> printCombinedLabelShipmentConfirmation;

[PXButton(CommitChanges = true)]
[PXUIField(DisplayName = "Print Labels/Packing Slip", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
public virtual IEnumerable PrintCombinedLabelShipmentConfirmation(PXAdapter adapter)
{
    var list = adapter.Get<SOShipment>().ToList();
    if (list.Count == 0) return list;

    var key = Guid.NewGuid();

    var printArgs = new PrintPackageFilesArgs
    {
        Shipments = list,
        Adapter = adapter,
        Category = PackageFileCategory.CarrierLabel
    };

    // Run first operation
    Base.LongOperationManager.StartAsyncOperation(key, ct =>
    {
        Base.PrintPackageFiles(printArgs, ct);
    });

    Base.LongOperationManager.WaitCompletion(key);

    // Queue the second operation separately
    PXLongOperation.StartOperation(Base, () =>
    {
        var graph = PXGraph.CreateInstance<SOShipmentEntry>();
        graph.Document.Current = graph.Document.Search<SOShipment.shipmentNbr>(list[0].ShipmentNbr);
        graph.printShipmentConfirmation.Press();
    });

    return list;
}

This way, the label printing happens first, and after it's complete, the shipment confirmation report runs in a new operation, allowing the report viewer to open as expected.

​@davidnavasardyan It doesn’t look like this works. It skips the label printing and just runs the Shipment Confirmation report. Below is my code. My version is 24.121.0004 if that makes a difference. 

public PXAction<SOShipment> printCombinedLabelShipmentConfirmation;
[PXButton(CommitChanges = true), PXUIField(DisplayName = "Print Labels/Packing Slip", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
public virtual IEnumerable PrintCombinedLabelShipmentConfirmation(PXAdapter adapter)
{

    var list = adapter.Get<SOShipment>().ToList();
    if (list.Count == 0) return list;

    var key = Guid.NewGuid();

    var printArgs = new PrintPackageFilesArgs
    {
        Shipments = list,
        Adapter = adapter,
        Category = PackageFileCategory.CarrierLabel
    };

    // Run first operation
    Base.LongOperationManager.StartAsyncOperation(key, async ct =>
    {
        // with/without await gives same issue
        await Base.PrintPackageFiles(printArgs, ct);
    });

    Base.LongOperationManager.WaitCompletion(key);

    // Queue the second operation separately
    PXLongOperation.StartOperation(Base, () =>
    {
        var graph = PXGraph.CreateInstance<SOShipmentEntry>();
        graph.Document.Current = graph.Document.Search<SOShipment.shipmentNbr>(list[0].ShipmentNbr);
        graph.printShipmentConfirmation.Press();
    });

  return list;

}

Hi ​@jacobslotta06 were you able to find a solution? Thank you!

No I wasn’t. I was able to get it to work if you print the shipment confirmation to DeviceHub, but I wasn’t able to have it open the shipment confirmation report in a new window and print the labels. It only does one or the other depending on the order in code.
