I have the same question as this topic which never received an answer:

 

I need to override the EmailPurchaseOrder action to do a simple update to a custom field.

		public delegate IEnumerable emailPurchaseOrder(PXAdapter adapter, [PXString] string notificationCD = null);
		[PXButton(CommitChanges = true), PXUIField(DisplayName = "Email PO")]
		[PXOverride]
		public virtual IEnumerable EmailPurchaseOrder(
			PXAdapter adapter,
			[PXString]
			string notificationCD = null, emailPurchaseOrder BaseMethod)
		{
			//Logic Here

I get an error that the optional parameter must be the last item in the method.

Any solutions for this?

Hi ​@Joe Schmucker 
Try this approach. The only thing I changed is that the parameter BaseMethod is now optional.

public delegate IEnumerable emailPurchaseOrder(PXAdapter adapter, [PXString] string notificationCD = null);
[PXButton(CommitChanges = true), PXUIField(DisplayName = "Email PO")]
[PXOverride]
public virtual IEnumerable EmailPurchaseOrder(PXAdapter adapter,
   [PXString]
   string notificationCD = null,
   emailPurchaseOrder BaseMethod = null)
{
   //Logic Here
}
