Trying to capture price list update in customer screen

Hi ​@jmc37 ,

To capture both the old and new values of the Price Class field when it's updated in the Customer screen, you can use either the FieldUpdated event handler or Persist.

You need to create one more custom field for capturing old value.

Those only retrieve the old fields. For the customer screen it isn’t working for getting the new value.

using PX.Data;
using static PX.Objects.AR.CustomerMaint;
namespace PX.Objects.AR
{
    public class CustomerMaint_Extension : PXGraphExtension<PX.Objects.AR.CustomerMaint>
    {
        public static bool IsActive() => true;

        public delegate void PersistDelegate();
        [PXOverride]
        public void Persist(PersistDelegate baseMethod)
        {
            var cPriceClassID =  Base.GetExtension<DefLocationExt>().DefLocation.Current.CPriceClassID;
            baseMethod();
        }
    }
}

Hi Stephen,

How to properly raise an exception when Customer’s Price Class value is empty on Save so that it will display error against cPriceClassID field?

Actually, got this code working fine:

bool anyError = false;

DefLocationExt extension = Base.GetExtension<DefLocationExt>();

var currentLocation = extension?.DefLocation?.Current;
if (currentLocation.CPriceClassID is null)
{
    anyError = true;
    extension.DefLocation.Cache.RaiseExceptionHandling(nameof(currentLocation.CPriceClassID), currentLocation, currentLocation.CPriceClassID, new PXException("Price Class is required", PXErrorLevel.Error));
}
if (anyError) throw new PXException(PX.Objects.Common.Messages.RecordCanNotBeSaved);
