Simple arithmatic function is not resulting in zero

This is absolutely bizarre. 2.4 - 1.2 = 1.2 and 1.2-1.2 = 0,
or so you'd think, except that Flash keeps telling me 1.2 - 1.2 =
-4.44089209850063e-16. Subtract 1.2 once more from
-4.44089209850063e-16 and you miraculously get -1.2. Even more
bizarre is that this only happens if the starting value is greater
than 2.4.
See attached code which began as something much more complex
but I've commented out absolutely EVERYTHING except for this little
bit of math and yet it keeps telling me that 0 is
-4.44089209850063e-16. But only if rpm is greater than 2.4 to start
with. If it's 2.4 or less, it does get to zero.
Thanks for any help.

1. because your computer uses binary arithmatic.
2. you must round to get zero but you don't need to round to
whole numbers. you can round to within 15 digits and then you'll
get zero and won't loose any significant accuracy for most
purposes.

Deletion of plannable values in a cell does not result in zero value

Hi,
In a planning report when I wanted to set the values in a plannable cell to '0', I just deleted the value in that cell without actually setting a '0' expecting a '0' to appear in that cell after I refresh my report. But instead I get my original value back in the cell. Is this standard behaviour or a bug or do I need to change some setting to get a '0'.
I run my planning reports on the portal.
Thanks.

Mathscript contourf function produces strange results

the code "contourf(magic(8))" typed into the mathscripts window produces a different result from the same single line in matlab. The resolution and colormap differences don't bother me, but the line fragments are clearly incorrect. This is a simple example of a problem I'm having in my data. Further, if I'd like to plot the contour line myself, the "hold on" function does not seem to work with the contour. Any help would be much appreciated. A simple example demonstrating both problems:
clf
colormap(jet)
contourf(magic(8));
hold on
plot(1:8,1:8,'r*')

Hello,
I have looked into this issue some more. I talked to the developer who wrote the colormap function and it turns out we do have all the colormaps. However, their use is not documented. They are passed to the function as an option, e.g. colormap('jet').
In addition, the order of calls matters. The colormap only applies to the current plot. If you generate a new one, the colormap disappears. Consequently, reverse the order of your colormap and contourf calls as follows:
contourf(magic(8));
colormap('jet')

Abs Function is not working for converting the negitive valies

Hi ,
   My requirement is from the sorce I'm getting Amount data (both negative and possitive values)
if the value is negative then i want to convert it as possitive value. that means always i want to pass possitive values to my target side.
For this i have used ABS function    AMOUNT (Source) ---> abs -
> AMOUNT (Target)
but now the problem is from the source I'm getting this value   <AMOUNT>60179010.00</AMOUNT>
but while mapping it is converting and giving as <AMOUNT>60179008</AMOUNT>
I didn't understand this functinality . actually Abs function should just convert the sign of the value but why the value is also giving as mismatch.
please suggest me some solution for this..
Regards
jain

What SP are you on?
There have been lot of bugs in terms of the arithmatic functions in XI. But most of the issues have been solved in this release - http://help.sap.com/saphelp_nw04/helpdata/en/44/a7b4355d867455e10000000a11466f/content.htm
I suggest in case u are not on that SP upgrade to it or use a simple java UDF to do the abs conversion.
The math class in java can help you - http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Math.html

Nested aggregate functions are not allowed

I need a calculation that divides a parcial value (based on a condition) by the total. It is something like that:
CALCULATION 1:
PARCIAL_VALUE = CASE WHEN DURATION >= :PARAMETER THEN MEASURE_VALUE ELSE 0 END
CALCULATION 2:
DIVISION = CASE WHEN MEASURE_VALUE = 0 THEN 0 ELSE PARCIAL_VALUE / MEASURE_VALUE END
Calculation 1 only works if I use a SUM before the CASE. If I don't use the SUM, the calculation doesn't aggregate.
I believe I also should add a SUM before the CASE of Calculation 2, but I can't. I got the error: Nested aggregate functions are not allowed.
I tried to merge the two calculations, but I got the same error. I also tried to create a calculated item in detail level in the Administrator, but it didn't work too.
How can I reformulate this calculation in order to avoid this error?

I got the correct result with this formula:
CALCULATION 1:
PARCIAL_VALUE = SUM(CASE WHEN DURATION >= FIXED_VALUE THEN MEASURE_VALUE ELSE 0 END)
CALCULATION 2:
DIVISION = PARCIAL_VALUE / SUM(MEASURE_VALUE)
It didn't return a division by zero error.
The calculation works and correctly aggregates the data when I use a fixed value in the CASE. When I change the fixed value by a parameter, the calculation 1 works perfectly, but calculation 2 doesn't aggregate.

RH9 Webhelp Search function is not working properly

Hi,
My organization is using RH9 for a Webhelp project. My company and our client are restricted to using IE9 for the online help I have created for this project, and our OS environment is Windows 7. When I generate using the Webhelp layout, with the TOC, Index and Search options chosen, my resulting browser window shows two frames. Left for the Contents/Index/Search and right for the content. In the left panel, there are three links at the top for Contents, Index and Search. When I click on the Search link, the only thing I see is the alphabet A-Z (which are links to filter items beginning with these letters (much like the index link) and a list of what I would say is garbage. For example, if I click on H, I see items like "half 1 2 3" or "held" or "honor # 1 2 3 4 5 6 7 8", etc. If I run my cursor down this list, I notice that maybe the word honor is a link. If clicked it brings up one of my topic pages. I can also click on the random numbers that appear, like clicking on 3 it brings up another topic page. The search function does not allow me to type in a search criteria, since there is no search field as well.
Do you have any suggestions for this issue? Is this a bug, or do I need to change settings somewhere within RH9? The same thing is happening when using this help project that is running on our clients server. Is there any suggestion you can give to try and make this work properly?

Rick, Thanks for stepping in. I assumed that was the reason why I was not receiving the search field, and that is fine for now. We have discussed with our client the possibility of having two different help projects one for each, but that decision was kind of put on the back burner.
However, the other issue I am having is still there and I don't quite understand why. Since I only have clickable A-Zs for the search, and it lists links much like the Index section, I'm still seeing lists of just numbers and characters (i.e., "# 1 2 3 4 5", or "%" or "& 1 2 3 4 5" sometimes all the way up to 18 or so). And each of these characters or numbers are clickable links as well to either page that doesn't contain that number or to nothing.
Doing a bit more research, I have noticed that a lot of these links are being picked up by the PDF file we have as part of the project. Our help project has a link to the documented version of the help in the form of a User Guide.pdf file. So the search is listing items from that guide like the heading numbers 1.0, 1.0.1, etc. Also each of these are clickable links that go nowhere. But then there is still the numbers 1, 2, etc that go to pages that don't have this anywhere on the page.
Do you have any insight as to why these types of things are being listed under Search at all? They make that selection look very messy and unorganized. Not professional at all. I have checked and tested the properties settings and can't seem to find what is causing this to happen. Any idea would be most appreciated!!

Palm Desk Top 6.2 Address Look Up Function Does Not Work In Windows 7

I recently upgraded my desk top computer's operating system from Windows Vista Home Premium to Windows 7 Home Premium.  I synchronize with a Palm Tx PDA.  HP PalmOS customer support Chat helped me work through a compatibility issue that was preventing display of Address, Calendar, Memo and To Do items on my desk top computer via the Palm Desk Top 6.2 application.  I now find that the address look up function does not work (although it worked fine when I was running Vista). Without success, I tried running the repair tool as well as reloading the software (both overlay and clean reinstall). I would appreciate any help or suggestions to fix?

Photoshop suddenly does not print to Epson 3880 - PROBLEM: Cannot print from Photoshop After restart error message appears: - "There was an error opening your printer. Printing functions will not be available until you have selected a printer and reopen

PROBLEM: Cannot print from Photoshop
After restart error message appears:
— “There was an error opening your printer. Printing functions will not be available until you have selected a printer and reopened any documents.”
• All print commands are greyed out and unavailable — even to call up the printer commands cannot be done.
The printer printed fine until about 2 weeks ago when this error message appeared. Printing continues from Pages, I-photo, preview etc. — only Photoshop fails.
The printer has been turned on and off, as have open documents been closed and open etc.. Preferences reset. Repeatedly I have read through blogs and forums and attempted to contact Adobe — all without results
Epson support struggled to find reason and several solutions were tried and they assume this is an Adobe problem.

PLSQL function does not return the correct number of rows?

Hey folks. I'm still green when it comes to writing PLSQL. It's fun, rewarding and very frustrating. Hence, I'm turning to the experts. If you folks can help me understand what I'm doing wrong here, I'd really appreciate it.
The code is somewhat specific to my company's product, but I think it should be easy to read and understand what I'm doing. If not, please let me know what I can clarify.
All i'm trying to do is determine if the most recent iteration of data available for a particular host is a full scan or not (level2). I go about this in the following manner:
1. get the operatingsystem id, it's scandate (preferred), the most recent scandate and it's scan status from a table of where all operating systems data lives. Loop through all the Oses
(from this I set v_osid, v_mostrecentscandate, v_scandate).
2. Before doing the crazy logic, pick the low hanging fruit
2a. if the the level2 status of the host is N, then v_level2 = 'N';
2b. if the level2 = 'Y' and the mostrecentscandate and scandate are identical, then v_level2 = 'Y';
2c. for all other cases, go to 3
3. Using v_mostrecentscandate, find all table id that may hold the most recent instance of data for the host
4. Loop through through the concatenation of that id + _base. If you find the id in those tables, then store the id for the next step.
5. When you I find the right id, I now concatenate the id + attrdata. For the host id, I look for any rows where attribute_value in (..) and the corresponding number_value is not null.
5b. set v_level2 = 'Y'
5c. otherwise, set v_level2 = 'N'
6 end the loop
7 wash, rinse, repeat for each OS.
create or replace package body mostrecentlevel2 as

I also realize I'm not providing the type or package code, and that's because I think I'm good on that. The code above compiles just fine without errors and when it runs, it only returns 6 consecutive rows.. I'm expecting 70K lol. So I know I'm doing something wrong.
Any thoughts?

Hey folks. I'm still green when it comes to writing PLSQL. It's fun, rewarding and very frustrating. Hence, I'm turning to the experts. If you folks can help me understand what I'm doing wrong here, I'd really appreciate it.
The code is somewhat specific to my company's product, but I think it should be easy to read and understand what I'm doing. If not, please let me know what I can clarify.Post a complete script that peoople who aren't as familiar with the application as you are can run to re-create the problem and test their ideas. In this case, that includes CREATE TABLE and INSERT statements for the tables used (just the columns needed for this job), a query that uses the function, and the results you want from that query given the data you posted.
All i'm trying to do is determine if the most recent iteration of data available for a particular host is a full scan or not (level2). I go about this in the following manner:
1. get the operatingsystem id, it's scandate (preferred), the most recent scandate and it's scan status from a table of where all operating systems data lives. Loop through all the Oses
(from this I set v_osid, v_mostrecentscandate, v_scandate).
2. Before doing the crazy logic, pick the low hanging fruit
2a. if the the level2 status of the host is N, then v_level2 = 'N';
2b. if the level2 = 'Y' and the mostrecentscandate and scandate are identical, then v_level2 = 'Y';
2c. for all other cases, go to 3
3. Using v_mostrecentscandate, find all table id that may hold the most recent instance of data for the host
4. Loop through through the concatenation of that id + _base. If you find the id in those tables, then store the id for the next step.
5. When you I find the right id, I now concatenate the id + attrdata. For the host id, I look for any rows where attribute_value in (..) and the corresponding number_value is not null.
5b. set v_level2 = 'Y'
5c. otherwise, set v_level2 = 'N'
6 end the loop
7 wash, rinse, repeat for each OS.

You're calling TO_DATE with a DATE argument. Why are you calling TO_DATE at all?
It seems like this condition:
((trunc(collect_start_time) - to_date(v_anchor))*24*60*60) <= ((to_date(v_mostrecentscandate) - to_date(v_anchor))*24*60*60) is equivalent to
TRUNC (collect_start_time) <= v_mostrecentscandateThat probably has nothing to do with why you're only getting 6 rows.

Produciton order status TECO, but WIP is not equal to zero

We checked produciton order status TECO (CO03)
but WIP is not equal to zero (KKAO)
Also, we found production order status show "rel" status in KKAO.
Why order status in CO03 is TECO, but show "REL" in KKAO?
Thanks in advance.

Hi,
We also had similar issue that the WIP is not equal to zero even though the status of the Process Order is DLV/TECO. When we analyzed, we found that few of the operations/resources/activityeps are not yet confirmed in the same month for the order. These operations/resources/activityeps are confirmed in subsequent month, then WIP got automatically Zero.
Also refer the SAP Note 530563 - WIP calculation: Status DLV and TECO. Which provide the details for how WIP will get calculated.
Thanks & regards,
ADI

ORA-04091:table XYZ is mutating,trigger/function may not see it ORA-06512

Hi everybody
i am facing mutating problem during data deletion fron XYZ table as
ORA-04091:table XYZ is mutating,trigger/function may not see it ORA-06512 at "user.procdure_name",line 39 ORA-065
i have table XYZ and have database trigger on this table
and also have procedure "user.abc" in this procedure m selecting data from xyz table

You didn't post the actual code. I was more interested in seeing table name and the trigger body.
Anyways, mutation problem comes when you refer the same table on the trigger, on which it is based for some data manipulation on that table.
For e.g, If inside your trigger body, you are doing INSERT on the same table, then it'll definitely result in mutation problem because this trigger will be fired endlessly (as it is after insert trigger).
Please mark answer as helpful / correct, if it helps you
