Linking Dates from Custom Date Field on PO Screen to Custom Date Field on PO Line

​@asingh 

You can achieve the requirement by using event handlers

Below is a sample implementation using the RowUpdated event on the POOrder graph.

public class POOrderEntryExt : PXGraphExtension<POOrderEntry>
{
    protected void POOrder_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
    {
        var row = (POOrder)e.Row;
        var rowOld = (POOrder)e.OldRow;

        if (!sender.ObjectsEqual<POOrderExt.usrETAGYDate, POOrderExt.usrBackOrderDate>(row, rowOld))
        {
            foreach (POLine line in Base.Transactions.Select())
            {
                var lineExt = line.GetExtension<POLineExt>();

                lineExt.UsrETAGY = row.GetExtension<POOrderExt>().UsrETAGYDate;

                if (lineExt.UsrBackOrder == true)

                    lineExt.UsrBackOrderPromiseDate = row.GetExtension<POOrderExt>().UsrBackOrderDate;


                Base.Transactions.Update(line);
            }
        }
    }
}

you can also consider using the FieldDefaulting event on the detail lines.

Thankyou

Hi ​@Saikrishna V thank you for your input and apologies for the late reply. After trying your suggestion, the following error was shown after I tried to ‘Publish Current Project’ from the ‘Publish’ menu:

For context, these are the steps I took:

1. Opened the customization project.
2. Opened the customized screen.
3. Clicked on ‘Form: Document’, clicked ‘Events’ tab, selected ‘RowUpdated’, clicked ‘ADD Handler’ and selected ‘Keep Base Method’ (see screenshot attached).

   

    

4. Inserted information and changed the data fields to match local instance.

I’m not sure if any of what I did was correct, but this sums up what was done and where it is now.

Appreciate any guidance / suggestions.

Thanks

Amit

Hello ​@asingh 

Thanks for the update, 

To fix this, try the below change — instead of using cache, use sender in the method signature and try package publish again.

// Original (causing issue)
protected void POOrder_RowUpdated(PXCache cache, PXRowUpdatedEventArgs e)

// Corrected version
protected void POOrder_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)

Thanks Sai
 

Hi ​@Saikrishna V the customization was successfully published, but unfortunately did not have any effect on the screen.

Thanks

​@asingh 

there is a small error: the keyword virtual is missing in syntax

protected virtual void POOrder_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e) {}

and also make sure to declare CommitChanges=true in aspx.

Thanks
