Simulation and Burn producing wildly different results

To try and make a long story short, I have constructed a very, very linear DVD (it's actually going to be turned into a VHS, which if you're wondering why, it's b/c of all things this is the cheapest and most efficient way for us to do Closed Captioning on a VHS program). There are a series of scenarios, each with 3 associated ending videos. For each of these videos, I have a menu declaring the upcoming video.
For ease, let's just call it 1A, 1B, 1C, and so on. When I simulate the program, everything works just fine. It goes through on a linear progression.
However, when I burn and test the program, the menus are all over the place. The videos are in the proper order, but video 2A is proceeded by menu 1B and video 2B is proceeded by 2A, etc., etc. There are about a dozen glitches like this on the disc.
Again, I'm fairly confident the project is set up correctly and a simulation of the project shows that. Is this just some crazy file corruption? Has anyone run into such a thing? It's quite disconcerting.

So I burnt it on a different system and had NO problems. Go figure. It must be some kind of corruption on my other system.

  • Same calculation producing two differing results

    Hi All
    I have some code in a user exit on save of a delivery (VL02N) that calculates the number of bags/pallets required to furnish that delivery.
    I am now adding the same code to a user exit on save a sales order (VA02) to calculate the number of bags/pallets again but when run it is producing differing results.
    the code is as follows:
    DATA: bag_weight(12) TYPE p DECIMALS 4.
    DATA: pallet_weight TYPE marm-umrez.
    DATA: bag_denominator TYPE i.
    bag_weight = pallet_weight / bag_denominator.
    Assuming pallet_weight = 1000 and bag_denominator = 40.
    On save of a delivery it is calculating bag_weight as 25.0000 (correct):
    On save of a sales order it is calculating bag_weight as 0.0025 (incoorect).
    All data declaration, code etc is the same. Does anybody have any clue as to why it would give two differing answers, I would not like to have to add a additional multiplication step to correct the result otherwise.
    Thanks in advance
    David

    Hi,
    Whenever you are using the Packed numbers, you need to check or set the program attribute fixed point arithmetic only as only this ensure that the decimal point is calculated correctly.
    Have a look at the help.sap.com documentation link:
    http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb2fd9358411d1829f0000e829fbfe/content.htm

  • "select count(*)" and "select single *" returns different result

    Good day!
    product version SAP ECC 6.0
    oracle10
    data transfers from external oracle db into customer tables using direct oracle db link
    sometimes I get case with different results from 2 statements
    *mytable has 10 rows
    *1st statement
    data: cnt type I value 0.
    select count( * ) into cnt from mytable WHERE myfield_0 = 123 and myfield_1 = '123'.
    *cnt returns 10 - correct
    *2nd statement
    select single * from  mytable WHERE myfield_0 = 123 and myfield_1 = '123'.
    *sy-dbcnt returns 0
    *sy-subrc returns 4 - incorrect, 10 rows are "invisible"
    but
    1. se16 shows correct row number
    2. I update just one row from "invisible" rows using se16 and 2nd statement returns correct result after that
    can not understand why
    thank you in advance.

    Thank you, Vishal
    but,
    general problem is that
    1. both statements have the same WHERE conditions
    2. 1st return resultset with data (sy-dbcnt=10), 2nd return empty dataset, but must return 1 in sy-dbcnt
    Yes, different meaning, you are right, but must 2nd must return 1, because of "select single *" construction, not 0.
    Dataset to process is the same, WHERE conditions are equal...
    I think the problem is that how ABAP interperets select count(*) and "select single *".
    Maybe "select count (*)" scans only PK from index page(s)? and "select single *" scans data pages? and something is wrong with that?
    I'm new in SAP and didn't find any SAP tool to trace dump of data and indexes pages with Native SQL.
    se16 shows all records.
    And why after simple manual update of just one record using se16 "select single *" returns 1?
    I've just marked one row to update, didn't change any data, then pressed "save".

  • Variance Scaling in Query and Web Template Showing Different Results

    Hi experts,
    I have the following problem - variance scaling in my query and web template are showing different results.
    My variance in column is set as follows:
    Formula: NODIM(A % B)
    Scaling Factor: 1
    I have a structure in row that uses Scaling Factor of 1,000.
    Let say the value of Column A is 120 and Column B is 100.
    When I execute the query, it will show 0.02
    However, when I execute the web template it will show the correct scaling i.e. 20.
    May I know what can I do to correct above scaling error?
    Thank you!

    You can not remove the scalling factor, but once you check the checkbox below the dropdown menu, the scalling factor will go away.
    I checked at my end and when I set the scalling fact as 1, I was getting 9.9% while I was expecting 9900%. When I removed the scalling factor I started getting 9900%.
    I would let you know if I came across anything else.
    What about the unit of Column A and B. Are they same or different?

  • Issues with iCloud synchronisation and contacts over two or more devices.  iTouch and iPad2 sync with different results from iMac.  Thoughts?

    Has any one experienced issues with iCloud synchronisation and contacts over two or more devices? The primary machine is an iMac running Lion. Address Book was created from vcf file (backup of address book prior to moving to iCloud). iTouch replicates Contacts just fine and matches the Address Book on the iMac. The iPad 2 does not showing only 123 contacts where there should be 200. I have turned off iCloud on both devices thus erasing the iCloud content of both devices and staring from scratch with both devices with identical results. Even turned off iCloud on the iMac and erased the Address Book and rebuilt with the same results. Anyone have any ideas or suggestions? I am going nuts.....

    To follow-up with this issue:
    I ended up performing a security wipe on my device. The security wipe finished, and I was about to reconnect with Exchange when I decided to visit our host's web site to see if they had any articles covering the issues I was experiencing. While they didn't have anything specific, I did find a step-by-step guide to connecting a BB10 device to Exchange... and right there at the end, it said "Do NOT enable memo sync."
    I contacted support, and the rep told me that OS 10 has an issue with memo sync and it can cause all sorts of unpredictable behavior. Now, whether or not this is accurate I can say this: So far, the device is not disconnecting and reconnecting like it was before. Problem is, is this a result of not enabling memo sync, or is this a result of the security wipe?
    I may have overlooked it, but I don't recall reading anything about that anywhere else. I'm tempted to try re-enabling the memo sync to see if everything blows up again. At least that way I can see for myself if the memo sync is a real issue. Of course, perhaps it's an issue with SherWeb (our host) specifically. Hm...
    Anyway, for those that were interested, and for those that may come along in the future with a similar situation, the strange behavior that I first reported is no longer happening. I just don't know if it was a result of a security wipe or a result of not enabling memo sync with Exchange.

  • Controls and timecode - same player, different result

    I need to look at video clips on-line on a laptop and a PC, both running Windows 7 32 bit and from within Firefox 3.6.3 with Flash 10.   But they behave differently even on the same video from the same site.  On one (the laptop) the visible screen is larger, there is a black border at the bottom with start/pause/stop controls, and a timecode.  On the other (the PC) no border, no controls, no timecode.
    How can this be?  .
    There are minor differences - a few decimal points -  in version numbers for Flash 10 (as well as for firefox itself, java and many other apps) but in all cases the PC is the more current.
    I've checked for differences in plug-ins, add-ons, default programs.  No obvious answer.
    Mybe there is some way of setting options within flash player so that it shows things like timecodes?
    Advice welcome!!!

  • Image Capture for Epson Scanner producing very dark results

    I recently upgraded to a new iMac running Mountain Lion. I have a new Epson Perfection v750 Pro scanner, which I use to scan film negatives. I had previously been working with this scanner on a Windows 7 PC. Using Image Capture, I am getting wildly different results -- the resulting scan is completely dark. Is there a setting that I am missing somewhere?
    I've attached a little preview picture that shows the difference between a scan of the same image, with my PC vs my Mac.

    There is no Epson scanner utility for Mountain Lion, it appears. Even Epson's FAQ defers to Image Capture and says it only provides software for image modification.
    http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?BV_UseBVCookie=yes&info Type=FAQ&oid=207953&foid=214278&cat=214269&subcat=214264
    Unfortunately Image Capture completely fails to provide the service it should be expected to. The 3rd party software VueScan seems like it would be adequate once I learned how to manipulate it a little more, but ultimately the only decision I can justify is to hook up the scanner to my Windows PC and use the TWAIN-based scan utility there.
    If there's anywhere I can make an official plea to Apple to get Image Capture in a workable state, feel free to point the way.

  • Do IMAQ Cast Image or IMAQ Linear averages give different results when using different computers that are running under Windows XP ?

    Hello
    I'm currently developping an image processing algorithm using Labview 7.1 and the associated IMAQ Vision tools. After several tests, I found a weird result. Indeed, I put the labview algorithm - including the IMAQ VI on the library to get sure that I use all the time the same VI - on my memory stick and used it on two different computers. I tested the same picture (still in my memory stick) and had two very different results.
    After several hours trying to understand why, I found that there were a difference between the results given by both computers at the very begining of the algorithm. Indeed, I used a JPEG file.
    To open it, I first create an Image with IMAQ Create (U8). Then, I open it.
    Then in my first sub-VI, I use IMAQ Cast Image to be sure that the picture is a U8 grayscale picture.
    Right after that, I use the IMAQ Linear Averages. The results of this VI are different on the two computers.
    I tried several time on the same picture : one computer always give me the same result but the two computers give me a different result. So there is no random variable on the results.
    So my question is : Do IMAQ Cast Image or IMAQ Linear averages give different results when using different computers that are running under Windows XP ?
    My bet is on IMAQ Cast Image but I'm not quite sure and I do not undestand why. The labview and IMAQ are the same on both computers.
    The difference between the two computer are above :
    Computer 1 :
    Pentium(R) 4 CPU 3.20GHz with a RAM of 1Go. The processor is an Intel(R).
    The OS is windows XP Pro 2002
    Computer 2 :
    Pentium(R) 4 CPU 2.80GHz with a RAM of 512Mo. The processor is an Intel(R).
    The OS is windows XP Pro 2002.
    If anybody can help me on this problem, it would be really helpful.
    Regards
    Florence P.

    Hi,
    Indeed it's a strange behaviour, could you send me your VI and your JPEG file, (or another file that reproduces) so that I could check this inthere ?
    I'll then try to find out what's happening.

  • Minimum on rows  and sums/ Summation on overral result required

    Dear All,
    If I have three shipments with three line items then I want to see the minimum for each key figure (in this case distance). This is becasue each shipment will not have an overall sum, but a number of shipments will have an overall total
    I am trying to achieve the following result:
    Shipment     Item                Distance
    1001           10                    3 miles
    1001           20                    3 miles
    1001           subtotal            3 miles (both items go to same customer)
    1002           10                    5 miles
    1002           subtotal            5 miles
    Overall result                        8 miles (this is the total distance)
    I am currently using exception aggregation (set to minimum on item) and this produces the following results:
    Shipment     Item                Distance
    1001           10                    3 miles
    1001           20                    3 miles
    1001           subtotal            3 miles
    1002           10                    5 miles
    1002           subtotal            5 miles
    Overall result                        3 miles
    This means that the overall result is wrong in the second case (I have tried playing with the aggregation by shipment number - but this was not successful).
    Would be really grateful if somebody could give me some ideas with this one,
    Thanks,
    Ron

    Since you didn’t upload your excel file, I’m not quite sure what’s your source data looks like.
    I don’t think this issue is caused by your formula, but I guess you really need use number 3 instead of 103 in your SUBTOTAL formula.
    Anyway, please try below possible solutions for this issue.
    1. Set up your formula firstly, then filter data. Rather than the other way around.
    2. Select the filter range before filter. Or use advanced filter(except  the row which including your  formula)
    3. Copy the formula to the next row, then delete the pervious formula row.
    If it didn’t bring any joy. It’ll be better if you can share your workbook with us.

  • XSLT producing different results via debugger and xslt.Transform()

    I'm producing the body of an email via an xsl. I've been having a problem with the html nested inside a <table> tag not displaying correctly. With a bit of help from the good folks over at the asp.net forums, I've tracked the problem down to getting
    different results if I run the xsl via the debugger or via a compiled transform.
    When I debug the xsl it produces
          <table border="1" cellpadding="4" cellspacing="0" style="..." id="tmsEmailTable">
            <tr>
              <th width="50%" align="center"><b>Issue</b></th>
              <th width="50%" align="center"><b>Resolution</b></th>
            </tr>
            <tr>
              <td>Missing Acknowledgement date</td>
              <td><p> Test test</p></td>
            </tr>
            <tr>
              <td>Missing Agent and/or Seller signature</td>
        </table>
    And that's absolutely correct and displays perfectly if I save the result as an html file. But when I use xslt.Transform(..), where xslt is a compiled transform, it produces
    <table border="1" cellpadding="4" cellspacing="0" style="..." id="tmsEmailTable">
                <tr><th width="50%" align="center"><b>Issue</b></th><th width="50%" align="center"><b>Resolution</b></th></tr>
                <tr>
                    <td>
                        Missing Acknowledgement date
                    </td>
                    <td></td>
                </tr>
            </table>
        </p><p> Test test</p></td></tr><tr>
            <td>Missing Agent and/or Seller signature</td>
            <td>
        </table>
    And to make it even more interesting, that extra </table> tag and the misplaced table data only occur on the first table row, but the table rows are generated by an xsl:for-each.
    The relevant bit of the xsl is:
              <table border="1" cellpadding="4" cellspacing="0" style="..." id="tmsEmailTable">
                <tr>
                  <th width="50%" align="center">
                    <b>Issue</b>
                  </th>
                  <th width="50%" align="center">
                    <b>Resolution</b>
                  </th>
                </tr>
                <xsl:for-each select="emailbody/checklist/item">
                  <xsl:if test="string-length(select='issue')>0">
                    <tr>
                      <td>
                        <xsl:value-of select="issue" disable-output-escaping="yes" />
                      </td>
                      <td>
                        <xsl:value-of select="resolution" disable-output-escaping="yes" />
                      </td>
                    </tr>
                  </xsl:if>
                 </xsl:for-each>
              </table>
    The code that generates the compiled transform and the (incorrect) output is:
                Dim xslt As XslCompiledTransform = New XslCompiledTransform(True)
                'Dim xslt As XslTransform = New XslTransform
                xslt.Load(templatePath) 
                Dim objStream As Stream = New MemoryStream(UTF8Encoding.UTF8.GetBytes(xmlData))
                Dim strbldrXML As StringBuilder = New StringBuilder()
                Dim objXmlReader As XmlReader = XmlReader.Create(objStream)
                Dim objXmlWriter As XmlWriter = XmlWriter.Create(strbldrXML)
                xslt.Transform(objXmlReader, objXmlWriter)
    I've checked that templatePath is pointing to the right file, and the source file I'm debugging the xsl against was copied from the xmlData parameter, so I know the same stuff is getting fed into it.
    I've been chasing this for days, and I'm about ready to quit and go get a job at a fast food joint. I'm not wonderful with xsl in general, or xsl in .NET in particular. Somebody PLEASE tell me I'm doing something stupid....
    Rebecca M. Riordan

    Thanks for the replay, Fred, but that wasn't the problem.
    I still don't know what the problem was, but in putting together a sample for review, I cleaned up the code a little (I inherited this), and while it
    appears to be functionally identical, it's working now. Since we're scheduled to go live on Friday, I'm gonna just take the win ;)
    In the unlikely event that anybody's curious, the original, non-functional code, looked like this:
    Public Function createEmailBody(ByVal templateType As String, ByVal xmlData As String) As String
                Dim templatePath, emailBody As String
                templatePath = Me.templatePath & "\" & templateType & ".xsl"
                Dim xpd As New XPathDocument(New StringReader(xmlData))
                Dim xslt As XslCompiledTransform = New XslCompiledTransform(False)
                xslt.Load(templatePath)
                Dim objStream As Stream = New MemoryStream(UTF8Encoding.UTF8.GetBytes(xmlData))
                Dim strbldrXML As StringBuilder = New StringBuilder()
                Dim objXmlReader As XmlReader = XmlReader.Create(objStream)
                Dim objXmlWriter As XmlWriter = XmlWriter.Create(strbldrXML)
                xslt.Transform(objXmlReader, objXmlWriter)
                emailBody = strbldrXML.ToString()
                Return emailBody
    End Function
    In cleaning it up, I wrote this:
    Public Function createEmailBody(ByVal templateType As String, ByVal xmlData As String) As String
                Dim xslt As XslCompiledTransform = New XslCompiledTransform(False)
                Dim templatePath As String = Me.templatePath & templateType & ".xsl"
                xslt.Load(templatePath)
                Dim reader As XmlReader = XmlReader.Create(New MemoryStream(UTF8Encoding.UTF8.GetBytes(xmlData)))
                Dim outSB As StringBuilder = New StringBuilder()
                Dim writer As XmlWriter = XmlWriter.Create(outSB)
                xslt.Transform(reader, writer)
                Dim emailBody As String = outSB.ToString()
                Return emailBody
    End Function
    As I said, they look functionally identical to me, but obviously they're not, because the second one works....

  • Validate the input file against a given schema inside an orchestration and producing 2 different files based on the validation result

    HI All,
    I have a situation.
    I need to validate the input file against a given schema inside an orchestration and producing 2 different files based on the validation result.
    A predefined success schema in case of  validation success and negative schema structure for validation failure.
    any advice ?

    Hi Rachit,I following the blog
    http://dietergobeyn.be/validating-biztalk-messages-orchestration/ and stuck in few things
    I created a helper class with the name Validation and following code
    [Serializable]
        public class Validation
            private bool _isValid = true;
            public bool Validate(XmlDocument document, Type schema)
                XmlSchemaSet set = new XmlSchemaSet();
                if (typeof(SchemaBase).IsAssignableFrom(schema) && !schema.IsNested)
                    set.Add((Activator.CreateInstance(schema) as SchemaBase).Schema);
                ValidationEventHandler eventHandler = new ValidationEventHandler(HandleValidationError);
                document.Schemas = set;
                document.Validate(eventHandler);
                return _isValid;
            private void HandleValidationError(object sender, ValidationEventArgs ve)
                _isValid = false;
    public static bool ValidateMessage(XLANGMessage msg)
    XmlDocument xDoc = new XmlDocument();
    xDoc = (System.Xml.XmlDocument)msg[0].RetrieveAs(xDoc.GetType());
    Type t = typeof(Schemas.External.Invoice_v3_1);
    Validation validation = new Validation();
    return validation.Validate(xDoc, t);
    First thing, Do i need to write the ValidateMessage method inside the helper class or not ??
    If inside, how to add the reference of schema files in the statement (Type t = typeof(Schemas.External.Invoice_v3_1);)
     I tried adding the reference of my schema project but it is showing error.

  • Same code gives different results in Matlab Script in Labview and Matlab

    I am implemeting a Matlab code into a LabVIEW application using Matlab script. When I import the exactly same code to the Matlab Script in LabVIEW it gives a different result than it is in Matlab. This code is a simulation code including first kind bessel functions. Using LabVIEW 7.1 and Matlab R14 service pack 3.

    Labview 8.5
    Matlab R2009b
    Attached are the graphs produced by matlab script in labview and in matlab.
    The minimum of graph produced by matlab code is below 1 and that in labview is above 1.
    Thanks a lot for your reply.
    Sorry, I haven't quantified the "sometimes" yet.

  • Filter expression producing different results after upgrade to 11.1.1.7

    Hello,
    We recently did an upgrade and noticed that on a number of reports where we're using the FILTER expression that the numbers are very inflated. Where we are not using the FILTER expression the numbers are as expected. In the example below we ran the 'Bookings' report in 10g and came up with one number and ran the same report in 11g (11.1.1.7.0) after the upgrade and got two different results. The data source is the same database for each envrionment. Also, in running the physical SQL generated by the 10g and 11g version of the report we get different the inflated numbers from the 11g SQL. Any ideas on what might be happening or causing the issue?
    10g report: 2016-Q3......Bookings..........72,017
    11g report: 2016-Q3......Bookings..........239,659
    This is the simple FILTER expression that is being used in the column formula on the report itself for this particular scenario which produces different results in 10g and 11g.
    FILTER("Fact - Opportunities"."Won Opportunity Amount" USING ("Opportunity Attributes"."Business Type" = 'New Business'))

    Thank you for the info. They are definitely different values since ones on the header and the other is on the lines. As the "Won Opportunity" logical column is mapped to multiple LTS it appears the OBI 11 uses a different alogorthim to determine the most efficient table to use in the query generation vs 10g. I'll need to spend some time researching the impact to adding a 'sort' to the LTS. I'm hoping that there's a way to get OBI to use similar logic relative to 10g in how it generated the table priority.
    Thx again,
    Mike

  • SQL Query produces different results when inserting into a table

    I have an SQL query which produces different results when run as a simple query to when it is run as an INSERT INTO table SELECT ...
    The query is:
    SELECT   mhldr.account_number
    ,        NVL(MAX(DECODE(ap.party_sysid, mhldr.party_sysid,ap.empcat_code,NULL)),'UNKNWN') main_borrower_status
    ,        COUNT(1) num_apps
    FROM     app_parties ap
    SELECT   accsta.account_number
    ,        actply.party_sysid
    ,        RANK() OVER (PARTITION BY actply.table_sysid, actply.loanac_latype_code ORDER BY start_date, SYSID) ranking
    FROM     activity_players actply
    ,        account_status accsta
    WHERE    1 = 1
    AND      actply.table_id (+) = 'ACCGRP'
    AND      actply.acttyp_code (+) = 'MHLDRM'
    AND      NVL(actply.loanac_latype_code (+),TO_NUMBER(SUBSTR(accsta.account_number,9,2))) = TO_NUMBER(SUBSTR(accsta.account_number,9,2))
    AND      actply.table_sysid (+) = TO_NUMBER(SUBSTR(accsta.account_number,1,8))
    ) mhldr
    WHERE    1 = 1
    AND      ap.lenapp_account_number (+) = TO_NUMBER(SUBSTR(mhldr.account_number,1,8))
    GROUP BY mhldr.account_number;      The INSERT INTO code:
    TRUNCATE TABLE applicant_summary;
    INSERT /*+ APPEND */
    INTO     applicant_summary
    (  account_number
    ,  main_borrower_status
    ,  num_apps
    SELECT   mhldr.account_number
    ,        NVL(MAX(DECODE(ap.party_sysid, mhldr.party_sysid,ap.empcat_code,NULL)),'UNKNWN') main_borrower_status
    ,        COUNT(1) num_apps
    FROM     app_parties ap
    SELECT   accsta.account_number
    ,        actply.party_sysid
    ,        RANK() OVER (PARTITION BY actply.table_sysid, actply.loanac_latype_code ORDER BY start_date, SYSID) ranking
    FROM     activity_players actply
    ,        account_status accsta
    WHERE    1 = 1
    AND      actply.table_id (+) = 'ACCGRP'
    AND      actply.acttyp_code (+) = 'MHLDRM'
    AND      NVL(actply.loanac_latype_code (+),TO_NUMBER(SUBSTR(accsta.account_number,9,2))) = TO_NUMBER(SUBSTR(accsta.account_number,9,2))
    AND      actply.table_sysid (+) = TO_NUMBER(SUBSTR(accsta.account_number,1,8))
    ) mhldr
    WHERE    1 = 1
    AND      ap.lenapp_account_number (+) = TO_NUMBER(SUBSTR(mhldr.account_number,1,8))
    GROUP BY mhldr.account_number;      When run as a query, this code consistently returns 2 for the num_apps field (for a certain group of accounts), but when run as an INSERT INTO command, the num_apps field is logged as 1. I have secured the tables used within the query to ensure that nothing is changing the data in the underlying tables.
    If I run the query as a cursor for loop with an insert into the applicant_summary table within the loop, I get the same results in the table as I get when I run as a stand alone query.
    I would appreciate any suggestions for what could be causing this odd behaviour.
    Cheers,
    Steve

    Yes, using COUNT(*) gives the same result as COUNT(1).
    I have found another example of this kind of behaviour:
    Running the following INSERT statements produce different values for the total_amount_invested and num_records fields. It appears that adding the additional aggregation (MAX(amount_invested)) is causing problems with the other aggregated values.
    Again, I have ensured that the source data and destination tables are not being accessed / changed by any other processes or users. Is this potentially a bug in Oracle?Just as a side note, these are not INSERT statements but CTAS statements.
    The only non-bug explanation for this behaviour would be a potential query rewrite happening only under particular circumstances (but not always) in the lower integrity modes "trusted" or "stale_tolerated". So if you're not aware of any corresponding materialized views, your QUERY_REWRITE_INTEGRITY parameter is set to the default of "enforced" and your explain plan doesn't show any "MAT_VIEW REWRITE ACCESS" lines, I would consider this as a bug.
    Since you're running on 10.2.0.2 it's not unlikely that you hit one of the various "wrong result" bugs that exist(ed) in Oracle. I'm aware of a particular one I've hit in 10.2.0.2 when performing a parallel NESTED LOOP ANTI operation which returned wrong results, but only in parallel execution. Serial execution was showing the correct results.
    If you're performing parallel ddl/dml/query operations, try to do the same in serial execution to check if it is related to the parallel feature.
    You could also test if omitting the "APPEND" hint changes anything but still these are just workarounds for a buggy behaviour.
    I suggest to consider installing the latest patch set 10.2.0.4 but this requires thorough testing because there were (more or less) subtle changes/bugs introduced with [10.2.0.3|http://oracle-randolf.blogspot.com/2008/02/nasty-bug-introduced-with-patch-set.html] and [10.2.0.4|http://oracle-randolf.blogspot.com/2008/04/overview-of-new-and-changed-features-in.html].
    You could also open a SR with Oracle and clarify if there is already a one-off patch available for your 10.2.0.2 platform release. If not it's quite unlikely that you are going to get a backport for 10.2.0.2.
