Stop Outgoing payment from particular users if BP credit balance is less

Question

Hi Experts
Please help me with the following issues
I want to be able to stop 3-4 specific users from generating outgoing payment if the following applies
1. the BP ledger Balance is Less than outgoing payment i.e if there is Rs. 100 credit balance then those users cannot make outgoing payment to BP more than Rs. 100
2. they also cannot make outgoing payments more than a set limit. for ex. if i say that user A has Rs. 50 as limit then he can generate only those payments where the outgoing payment amount is MAximum rs.50 even though the ledger balance is Rs. 150
I feel that this can be done through sp_transaction notification please help me with the SQL code for the same 
thanks

Please use the following code as a guideline and test it.   In the code below the first select statement gets the User Code of the user adding the Outgoing Payment.  this is your starting point to validate this transaction further.
In the first IF statement I am checking if the user code = 1 and checking the outgoing payment total against the BP balance and if it is greater message will be displayed.
In the Second if I am checking if the Outgoing payment amount is great than 100 and displaying a message.
This code does not use your current limit stored at the user table but has been constructed based on your future interest to hardcode values.
Please get the user codes corresponding to the users by running this query either in SQL or in SBO
SELECT T0.UserID, T0.U_NAME AS 'User Name' FROM  [dbo].[OUSR] T0
SBO_SP_TransactionNotifiation code is below
IF @object_type = '46' AND @transaction_type = 'A'
BEGIN
     declare @usercode int
    select @usercode = t0.usersign
    from [dbo].[ovpm] t0 where t0.docentry = @list_of_cols_val_tab_del
     if @usercode = 1
     begin
          if exists (select t0.docnum from [dbo].[ovpm] t0
              inner join [dbo].[ocrd] t1 on t0.cardcode = t1.cardcode
                where t0.doctotal > -1*t1.balance AND t0.docentry = @list_of_cols_val_tab_del)
          begin
               select @error = 1, @error_message = 'Payment total cannot be greater than BP balance'
          end
     end
     if @usercode = 5
     begin
          if exists (select t0.docnum from [dbo].[ovpm] t0
              inner join [dbo].[ocrd] t1 on t0.cardcode = t1.cardcode
                where t0.doctotal > 100 AND t0.docentry = @list_of_cols_val_tab_del)
          begin
               select @error = 1, @error_message = 'Payment total is greater than permitted limit'
          end
     end
END
All the very best
