How to find the SoLine.UsrCustomerConfig field in the invoice/AR files?

Hi ​@Phalbert ,

The custom field SoLine.UsrCustomerConfig on the Sales Order line (SOLine) can be mapped to the AR Invoice line (ARTran) during the invoice creation process from the Sales Order. To achieve this, you need to do a small customization

1. Extend the ARTran DAC
2. Extend the SOInvoiceEntry Graph

Example:
public class ARTranExt : PXCacheExtension<ARTran>
{
    #region UsrCustomerConfig
    [PXDBString(50)]
    [PXUIField(DisplayName = "Customer Config")]
    public virtual string UsrCustomerConfig { get; set; }
    public abstract class usrCustomerConfig : PX.Data.BQL.BqlString.Field<usrCustomerConfig> { }
    #endregion
}

public class SOInvoiceEntry_Extension : PXGraphExtension<SOInvoiceEntry>
{
    protected virtual void ARTran_RowInserting(PXCache sender, PXRowInsertingEventArgs e)
    {
        ARTran row = e.Row as ARTran;
        if (row == null) return;

        SOLine soLine = PXSelect<SOLine,
            Where<SOLine.orderType, Equal<Required<SOLine.orderType>>,
            And<SOLine.orderNbr, Equal<Required<SOLine.orderNbr>>,
            And<SOLine.lineNbr, Equal<Required<SOLine.lineNbr>>>>>>.Select(Base, row.SOOrderType, row.SOOrderNbr, row.SOOrderLineNbr);

        if (soLine != null)
        {
            var rowExt = PXCache<ARTran>.GetExtension<ARTranExt>(row);
            var soExt = PXCache<SOLine>.GetExtension<SOLineExt>(soLine);
            rowExt.UsrCustomerConfig = soExt?.UsrCustomerConfig;
        }
    }
}
