How to change auto numbering to existing auto numbering sequence in Acumatica? - acumatica

Question

In Cash Sales (AR304000 screen) i want to set it's auto numbering sequence from invoice number sequence to payment number sequence.
i tried the following code but to no avail. saving new sales throws an error. see attached photo for the error.
here is my DAC code:
public class ARCashSaleExtension : PXCacheExtension<ARCashSale>
{
#region RefNumber
[PXDBString(15, IsKey = true, InputMask = ">CCCCCCCCCCCCCCC", IsUnicode = true, BqlField = typeof(**PX.Objects.AR.ARPayment.refNbr**))]
[PXDefault()]
[PXUIField(DisplayName = "Reference Nbr.", Visibility = PXUIVisibility.SelectorVisible)]
[ARPaymentType.RefNbr(typeof(Search2<ARCashSale.refNbr,
InnerJoinSingleTable<Customer, On<ARCashSale.customerID, Equal<Customer.bAccountID>>>,
Where<ARCashSale.docType, Equal<Current<ARCashSale.docType>>,
And2<Where<ARCashSale.origModule, NotEqual<BatchModule.moduleSO>, Or<ARCashSale.released, Equal<boolTrue>>>,
And<Match<Customer, Current<AccessInfo.userName>>>>>, OrderBy<Desc<ARCashSale.refNbr>>>), Filterable = true)]
[**ARPaymentType.Numbering()**]
[PXFieldDescription]
public String RefNbr
{
get;
set;
}
#endregion
}

I think you should use AutoNumberAttribute instead of ARPaymentType.Numbering attribute.
[AutoNumber(typeof(ARCashSale.docType), typeof(ARCashSale.docDate),
new string[] { CashSale, CashReturn },
new Type[] { typeof(ARSetup.paymentNumberingID), typeof(ARSetup.paymentNumberingID) })]
Besides, I can't see any reasons to use ARPaymentType.RefNbr attribute instead of ARCashSaleType.RefNbr attribute.
One more thing: from my point, it's better to use Cache_Attached on graph extension for rewriting attributes on one field instead of creating DAC extension.
Here is an example of Graph extension with CacheAttached:
public partial class ARCashSaleEntryExt : PXGraphExtension<ARCashSaleEntry>
{
[PXMergeAttributes(Method = MergeMethod.Merge)] // that attribute is here to keep all attributes of base field except the one that should be replaced.
[AutoNumber(typeof(ARCashSale.docType), typeof(ARCashSale.docDate),
new string[] { ARDocType.CashSale, ARDocType.CashReturn },
new Type[] { typeof(ARSetup.paymentNumberingID), typeof(ARSetup.paymentNumberingID) })]
public virtual void ARCashSale_RefNbr_CacheAttached(PXCache sender)
{
}
}
