GetFormulaText show wrong recordselectionformula after installing SP4

Question

Hi,
I have a very strange problem after installing the sp4 of CR2008:
I am working with the following code to read a recordselection formula of a report:
                DataDefController dataDefController = _reportClientDocument.DataDefController;
                FilterController recordFilterController = _reportClientDocument.DataDefController.RecordFilterController;
                string oldRecordFilter = recordFilterController.GetFormulaText();
                string newRecordFilter = string.Empty;
I know that I have many possibilities to get the formula, f.e. the Property freeeditingtext or the filteritems collection. But this method is working fine since month.
I have a report with this selectionformula:
{Belegdruck.EBD.SachGrp}= "6460" and
{Belegdruck.EBD.Esintern} = "0" and
{t_ZAEHLER.zaehler} <= {Belegdruck.EBD.Menge}
And this is what the GetformulaText-function shows me in my program after installing SP4:
(   (  {Belegdruck.EBD.SachGrp} = "6460"  AND  {Belegdruck.EBD.Esintern} = "0"  )   AND   (   NOT  {t_ZAEHLER.zaehler} <= {Belegdruck.EBD.Menge}  )   ) 
Unbelievable. As you see, the systems put a NOT before the last if-part. I don't know why, but if I change the operand <= to < or = then everything is working fine and the selectionformula is unchanged.
The cause of problem is definitive SP4 because we did not change the program or the report. I think the reason is the parser. Because if I change the formula to a 'complex' formula which the parser cannot understand, then the formula keeps unchanged. for tests we put Local numberVar dummy := 1; in the beginning of the formula., so that the parser does not pars the formula.
Does anybody know if there is a chance to disable the formula parser or does anybody knows this problem?
I have opened a case at the sap-bo-support. I hope that they can help me.
Thank you.
Joerg

This is a known issue. See KB [1584095 - A boolean NOT is added at the beginning of a record selection formula when the report is loaded by the Crystal Reports .NET SDK|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333533383334333033393335%7D.do].
The fix is done for this issue and has been added to Fix Pack 4.1 - ETA: October 2011
