What values are returned?

RE: Isolation Level

Debugging a script like this is quite tricky without any data to test against. Try running this:
--ALTER Procedure [dbo].[BS_Voucher_CreateVoucher]
DECLARE
@vouchertypeID int = 1,
@denomination int = 100,
@quantity int = 10,
@amountvalue int...

RE: Isolation Level

Thanks. Try this. With multiple dml statements it still requires a transaction and error handling:
ALTER Procedure [dbo].[BS_Voucher_CreateVoucher]
@vouchertypeID int = 1,
@denomination int = 100,
@quantity int = 10,
@amountvalue int = 100,
@userid varchar(50)...

Middle right, 15-20 minutes early. It was good, very thorough. Some excellent questions were asked - not too edge-case.

I'm sure there's an easier (and safer) way of doing this.

@pToStore int = 1004,
@pSTN VARCHAR(20) = 0 output

Which column of the VALUES clause of the INSERT statement is it?
'V'+@retval + Replace( Str( @max-2 + @count, 7), ' ', '0') ?
seems likely, but you have no column...

Why isn't 41287 the second of a pair?

RE: Isolation Level

You're having problems with this mainly because you are working with one row at a time. Your control table is updated once for each row inserted, instead of updating it...
