Throw error in SQL Server 2008 R2 - sql-server-2008-r2

Question

I'm working with SQL Server 2008 R2 and I have an stored procedure where I'm trying to throw errror
throw 50001, 'Couldnot process,Please verify Transaction ID and EmbossLine', 1
But the query doesn't get executed and throws error on 50001. It was working fine on SQL Server 2012. I think there is some issue with versions. Is there anyother way I can throw error in SQL Server 2008 R2?
This is my stored procedure:
Alter procedure [dbo].[spGetRedemption]
#pan varchar(19),
#transId bigint
AS
Begin
if EXISTS(select * from POS_Transactions where ID=#transId)
Begin
select
PT.ID, PT.TransactionDate, M.MerchantName1,
PT.TerminalID, PT.BatchNumber, PT.SequenceNumber, PT.PAN,
C.EmbossName, PT.TotalAmount, PT.CurrencyCode,
TT.TransactionType, PT.InvoiceNumber
from
POS_Transactions PT
inner join
Terminal T on T.TerminalID = PT.TerminalID
inner join
Merchant M on M.MerchantID = T.MerchantID
inner join
Card C on C.EmbossLine = PT.PAN
inner join
TransactionType TT on TT.TransactionTypeID = PT.TransactionTypeID
where
PT.ID = #transId
and PT.PAN = #pan
END
Else
Begin
throw 50001, 'Couldnot process,Please verify Transaction ID and EmbossLine', 1
END
End

Throw is not available in SQL Server 2008R2; it was first introduced in SQL Server 2012.

The alternative would be to use Raiserror (note; only 1 E in the middle; it's not RaiseError).
From the above link, there are some differences between these methods:
RAISERROR statement
If a msg_id is passed to RAISERROR, the ID must be defined in sys.messages.
The msg_str parameter can contain printf formatting styles.
The severity parameter specifies the severity of the exception.
THROW statement
The error_number parameter does not have to be defined in sys.messages.
The message parameter does not accept printf style formatting.
There is no severity parameter. The exception severity is always set to 16.
