How to add Lot/Serial Nbr selector custom column.

If any one know how to add custom column on lot serial number selector please guide.

 ​@aiwan Hello,
Thanks for reply I tried like this but not showing lotserial number selector one more column. Can you please suggest.

 public class TSINLotSerialNbrAttribute : INLotSerialNbrAttribute
 {
     public TSINLotSerialNbrAttribute() : base() { }
     public TSINLotSerialNbrAttribute(Type inventoryType, Type subItemType, Type locationType, Type costCenterType)
         : base(inventoryType, subItemType, locationType, costCenterType)
     {
         // Re-initialize the selector with your custom field
         base.InitializeSelector(
             GetLotSerialSearch(inventoryType, subItemType, locationType, costCenterType),
             typeof(INLotSerialStatusByCostCenter.lotSerialNbr),
             typeof(INLotSerialStatusByCostCenter.siteID),
             typeof(INLotSerialStatusByCostCenter.locationID),
             typeof(INLotSerialStatusByCostCenter.qtyOnHand),
             typeof(INLotSerialStatusByCostCenter.qtyAvail),
             typeof(INLotSerialStatusByCostCenter.expireDate),
             typeof(INLotSerialStatusByCostCenterExt.usrCustomField)
         );
     }

     public TSINLotSerialNbrAttribute(Type inventoryType, Type subItemType, Type locationType, Type parentLotSerialNbrType, Type costCenterType)
         : base(inventoryType, subItemType, locationType, parentLotSerialNbrType, costCenterType)
     {
         // Re-initialize the selector with your custom field
         base.InitializeSelector(
             GetLotSerialSearch(inventoryType, subItemType, locationType, costCenterType),
             typeof(INLotSerialStatusByCostCenter.lotSerialNbr),
             typeof(INLotSerialStatusByCostCenter.siteID),
             typeof(INLotSerialStatusByCostCenter.locationID),
             typeof(INLotSerialStatusByCostCenter.qtyOnHand),
             typeof(INLotSerialStatusByCostCenter.qtyAvail),
             typeof(INLotSerialStatusByCostCenter.expireDate),
             typeof(INLotSerialStatusByCostCenterExt.usrCustomField)
         );
     }

In Shipment graph:
 [TSINLotSerialNbrAttribute(typeof(SOShipLine.inventoryID), typeof(SOShipLine.subItemID), typeof(SOShipLine.locationID), typeof(SOShipLine.costCenterID), PersistingCheck = PXPersistingCheck.Nothing)]
 protected virtual void SOShipLine_LotSerialNbr_CacheAttached(PXCache cache)
 {

 }

Thanks

​@noorula77 you have to add another parameter to your TSINLotSerialNbrAttribute i.e

public TSINLotSerialNbrAttribute(Type inventoryType, Type subItemType, Type locationType, Type parentLotSerialNbrType, Type costCenterType, Type usrCustomColumn) : base(inventoryType, subItemType, locationType, parentLotSerialNbrType, costCenterType, usrCustomColumn)

​@aiwan Thanks for suggestion .I tried it is not allowing getting error 

Severity	Code	Description	Project	File	Line	Suppression State
Error (active)	CS1729	'INLotSerialNbrAttribute' does not contain a constructor that takes 6 arguments	

​@noorula77 

you need to add your field to InitializeSelector too

base.InitializeSelector( GetLotSerialSearch(inventoryType, subItemType, locationType, costCenterType, usrCustomField), typeof(INLotSerialStatusByCostCenter.lotSerialNbr), typeof(INLotSerialStatusByCostCenter.siteID), typeof(INLotSerialStatusByCostCenter.locationID), typeof(INLotSerialStatusByCostCenter.qtyOnHand), typeof(INLotSerialStatusByCostCenter.qtyAvail), typeof(INLotSerialStatusByCostCenter.expireDate), typeof(INLotSerialStatusByCostCenterExt.usrCustomField) );

Hi ​@aiwan 
I have added the column in the field list, and it is now visible. I want to display data in this column only when the shipment's lot serial number matches the purchase receipt's lot serial number. In that case, the corresponding custom column data from the purchase receipt should be displayed.
I tried using RowSelected and FieldSelecting but not worked.

 protected void SOShipLine_RowSelected(PXCache cache, PXRowSelectedEventArgs e)
 {

     var row = (SOShipLine)e.Row;
     if (row == null) return;

     POReceiptLine pOReceiptline = PXSelect<POReceiptLine,
             Where<POReceiptLine.inventoryID, Equal<Required<POReceiptLine.inventoryID>>,
             And<POReceiptLine.siteID, Equal<Required<POReceiptLine.siteID>>,
             And<POReceiptLine.locationID, Equal<Required<POReceiptLine.locationID>>>>>>
             .Select(Base, row.InventoryID, row.SiteID, row.LocationID);

     POReceipt pOReceipt = PXSelect<POReceipt,
 Where<POReceipt.receiptType, Equal<Required<POReceipt.receiptType>>,
 And<POReceipt.receiptNbr, Equal<Required<POReceipt.receiptNbr>>>>>
 .Select(Base, pOReceiptline.ReceiptType, pOReceiptline.ReceiptNbr);
     if (row.LotSerialNbr == pOReceiptline.LotSerialNbr)
     {
         INLotSerialStatusByCostCenter iNLotSerialStatus = PXSelect<INLotSerialStatusByCostCenter,
                 Where<INLotSerialStatusByCostCenter.inventoryID, Equal<Required<INLotSerialStatusByCostCenter.inventoryID>>,
                 And<INLotSerialStatusByCostCenter.siteID, Equal<Required<INLotSerialStatusByCostCenter.siteID>>,
                 And<INLotSerialStatusByCostCenter.locationID, Equal<Required<INLotSerialStatusByCostCenter.locationID>>>>>>
                 .Select(Base, row.InventoryID, row.SiteID, row.LocationID);
         iNLotSerialStatus.GetExtension<INLotSerialStatusByCostCenterExt>().UsrCustomField = pOReceipt.GetExtension<POReceiptExtensionsTSExt>().Usrreceiptsad;
     }
 }

Might be worth trying to declare the extensions seperately, then using e.Cache.SetValue<>() to set the field value.
