Acumatica Generic Inquiry Adding to Inquiries Menu (Automation Steps) - customization

Question

Adding GIs to the report menu is easy enough but in this Technical Tuesday post Doug describes some additional steps that need to be followed with customization in order to add a GI to the INQUIRIES menu:
Anybody have any luck following his steps? I kept getting lots of validation errors with the code he shared and would appreciate a better explanation.
After the customization step, we just have to add it to the Automation Step.

Answer 1

Please use below customization code until we fix the issues with the Technical Tuesday post.
using System;
using System.Collections;
using PX.Data;
using PX.Objects.PO;
namespace PXDemoPkg
{
public class POOrderEntry_Extension : PXGraphExtension<POOrderEntry>
{
public PXAction<POOrder> inquiry;
[PXUIField(DisplayName = "Inquiries", MapEnableRights = PXCacheRights.Select)]
[PXButton]
protected virtual IEnumerable Inquiry(PXAdapter adapter,
[PXInt] [PXIntList(new int[] { 1, 2, 3 },
new string[] { "Vendor Details", "Activities", "PO Prepayments" })] int? inquiryID)
{
if (inquiryID == 3)
{
POOrder order = Base.Document.Current;
string giURL = PXGenericInqGrph.INQUIRY_URL;
string gIName = "POprepayments";
string sParameter1Name = "POnumber";
string sParameter1Value = order.OrderNbr;
string url = String.Format("{0}?Name={1}&{2}={3}", giURL, gIName, sParameter1Name, sParameter1Value);
throw new PXRedirectToUrlException(url, PXBaseRedirectException.WindowMode.New, true, "POprepayments-GI");
}
else
return Base.inquiry.Press(adapter);
}
}
}
