Print Checks, select "Not Printed", and print again... without trace!?

Question

Hello all:
I have already sent this to Product Support, but they requested me to open a thread in this forum. So here's the issue:
In SAP Business One it is possible to print a cheque, in the confirmation window select "Not printed", and then print the cheque again with another number (on unnumbered check stock paper). This creates a hole in the cheque numbering series, that is not explainable to auditors, and creates the possibility of fraud (hey, print two checks instead of one, but have one outgoing payment only). Of course in one way or another it has to be possible to print a cheque again, but my problem is that SAP B1 creates no trace of it whatsoever. The ACHO (cheque history) table is completely empty, the CHO2 table also doesn't have the "Not printed" cheques, and in OCHO only the last cheque number is stored.
I also can't block the "Not printed" option, because the SBO_SP_TransactionNotification is not executed when you print cheques or confirm cheque numbers.
As a workaround for audit requirements I have thought of setting up a trigger to log all updates to OCHO so I could create reports from this, but creating Triggers is not allowed either, so I'm kind of stuck.
Am I the only consultant being confronted with this situation, or how are your clients dealing with this issue? I definitely need a solution for this...
Thanks and best regards,
Joerg.
PS: Using the following query I am identifying the skipped numbers:
SELECT
     T0.AcctNum,
     'Missing from' = (SELECT MAX(CheckNum) FROM OCHO WHERE CheckNum < T0.CheckNum AND AcctNum = T0.AcctNum) + 1,
     'Missing to' = CASE WHEN (SELECT MAX(CheckNum) FROM OCHO WHERE CheckNum < T0.CheckNum AND AcctNum = T0.AcctNum) + 1 <> T0.CheckNum - 1 THEN T0.CheckNum - 1 ELSE 0 END,
     'Qty. missing' = T0.CheckNum - (SELECT MAX(CheckNum) FROM OCHO WHERE CheckNum < T0.CheckNum AND AcctNum = T0.AcctNum) - 1
FROM
     OCHO T0
WHERE
     (T0.CheckNum - (SELECT MAX(CheckNum) FROM OCHO WHERE CheckNum < T0.CheckNum AND AcctNum = T0.AcctNum) <> 1
     AND (SELECT MAX(CheckNum) FROM OCHO WHERE CheckNum < T0.CheckNum AND AcctNum = T0.AcctNum) <> 0
     OR (SELECT MAX(CheckNum) FROM OCHO WHERE CheckNum < T0.CheckNum AND AcctNum = T0.AcctNum) IS NULL)
     AND T0.PmntDate > '20090901'
     AND T0.Canceled = 'N'
     AND T0.Printed = 'Y'
ORDER BY
     T0.AcctNum,
     T0.CheckNum

1) I tried Print Therapy and after I had repaired Permissions the problem was solved (some permission problems were found) until the next restart.
2) Then I tried to stop and start again the cupsd process and again the problem was solved until the next restart of the computer.
3) Then I replaced the cupsd.conf file with a new one but the app asked to restart the computer and after this the problem was back.
4) Print Therapy does not find any problems neither in the properties of the root user nor in the current user or any other group.
5) Also the verification of the temporary files find no problems.
In conclusion I think that the problem lies in the cupsd process because when stopped and restarted (we can forget that by Repairing Permissions actually we restart cupsd) I have no problem until the next restart of the computer.
