Override GenerateLotSerial from LSINTran class

@edsonvelez64 Try creating a new custom LSINTran like this:
 

public class LSINTranCustom : LSINTran
{
     public override IEnumerable GenerateLotSerial(PXAdapter adapter)
     {
        base.GenerateLotSerial(adapter);
     }
}

And create a graph extension for INReceiptEntry overriding the lsselect view with your new custom class:
 

public class INReceiptEntryExt : PXGraphExtension<INReceiptEntry>
{

   public LSINTranCustom lsselect;
}
