Conditionally make custom field on Sales Order mandatory when sales order type = "XR"

Thank you, this worked in making it visible or invisible depending on order type. However the fields still not mandatory

@fmrubi11 give [PXDefault] attribute to field

setting [PXDefault()] in the DAC will also be trigger even when order type is not “XR” and will not allow saving of document

@fmrubi11 

Try this attribute in Field 

[PXDefault(PersistingCheck = PXPersistingCheck.Nothing)]

Hi @fmrubi11 

Do the validation on RowPersisting checking for the order type XR.

[PXLocalizable()]
public static class Messages
{
	public const string FieldErrorMessage = "Field Error Message";
	public const string ErrorMessage = "Error Message";
}

public static class SOOrderTypeConstantsExt
{
	public static string XR { get { return new xr().Value; } }

	public class xr : PX.Data.BQL.BqlString.Constant<xr>
	{
		public xr() : base("XR") { }
	}
}

protected void _(Events.RowPersisting<SOOrder> e)
{
	if (e.Row != null)
	{
		PXEntryStatus entryStatus = e.Cache.GetStatus(e.Row);
		if (entryStatus == PXEntryStatus.Inserted || entryStatus == PXEntryStatus.Updated)
		{
			SOOrder so = e.Row as SOOrder;
			SOOrderExt ext = e.Row.GetExtension<SOOrderExt>();
			if(so.OrderType == SOOrderTypeConstantsExt.XR)
			{
				if(ext.UsrField == null /* && <YOUR BUSINESS RULE> */)
				{
					e.Cache.RaiseExceptionHandling<SOOrderExt.usrField>(e.Row, null, new PXSetPropertyException(Messages.FieldErrorMessage, PXErrorLevel.Error));
					throw new PXException(Messages.ErrorMessage);
				}
			}
		}
	}
}

Happy to help

Using [PXUIRequired] would possibly be a less verbose option, as indicated here.
