Why SID is requuired?
Hello Experts,
I have a basic doubt in Star schema.
why do we need SID.as the SID table has only one entry for each characteristic value, so why can't the value of the characcteristic be directly used in the dimension table instead of SID.
(satandard example in BWtraining material)
Dimension : Customer
SID table : Customer_ID , SID_CUST(primary key : Customer_ID)
Customer Dimensional Table: DIM_ID_CUST,SID_CUST(why can't we directly use Cutomer_ID instead of SID_CUST)
I'll apprecaite your kind explanation on this.
Thank you very much!!
Best Regards,
Praveen
Praveen,
SID forms the base of the extended Star Schema - please go through the dimensional model availabls on help.sap.com to understand the Extended Star Schema where masters are kept separate.

Why SIDs start with 2 in master data S Tables?
Hello All,
When we create infoobjects, S table(/BIC/S...) is created to store SIDs and respective values.
However, these SIDs start with 2 and not 1.
Please, can anyone tell what is reason for this.Hi,
This is happening due to number range maintainance for SID values in your system.
Check below article for more information,

Is SID allowed to show up in /etc/hosts file?
Experts:
I am looking into a /etc/hosts which has something I never saw before.
Every entry in that /etc/hosts file has a format as follows:
123.23.456.678 CHERRY CHERRY.RIO.COM SID CHERRY.BRAVO.NET
For example:
123.23.456.678 CHERRY CHERRY.RIO.COM PRO CHERRY.BRAVO.NET
Observation:
0) WHY SID (here is PRD) gets into the hosts file? Would it cause some issues?
1) each entry has 2 aliases ;
2) "nslookup CHERRY.RIO.COM "
2a) will return the correct IP address IF I run this nslookup on the server
2b) will say "non-exist domain" on my PC
3) "nslookup CHERRY.BRAVO.NET"
3a) will say "non-exist domain" IF I run nslookup on the server
3b) will give the correct IP address on my PC
Thank you for help.Hi,
If your system in domain than the entries look like below
192.192.192.192 prdserver prdserver.na.jjjjjjj.com
Prd server is an host name where your SAP application is running/installed & prdserver.na.jjjjjjj.com is a hostname in domain

Thank you for help.Hi,
The nslookup is trying to resolve the address via the DNS. If you are not using a DNS, you cannot resolve this hostname via your local machine.. In order to do that, you should add the entry to your local hosts file.
I don't think there is any harm in using aliasses in that way, but it looks rather strange though..
Ask your system administrator why the setup of the hosts file is like this. He is responsible for this..
Kind regards,

Windows Update files: Security permissions has "unknown user"
Ok, this is weird. I have 30 files added in a November Windows update with a compile date or add-to date of 11/21/14. If I look at one of the files. MsSpellCheckingFacility.exe. I can see it is a legit file.
https://www.virustotal.com/en/file/e9dcf987838e9a70fca4e1b1dda217bd1e309cd4f6bac47402120f76aac6edc7/analysis/
However, the security permissions on the file are strange. The user TrustedInstaller is the owner. Now that seems to be typical when the file is a Microsoft updated file. However, the file also has a user added that is unknown.
user ? S-1-14-21
Umm, why is this? Its 30 files like this all REAL Microsoft files....all apparently part of the update. All scanned against virustotal as being revised about that date/time. Did Microsoft release an Update Build with files as a part
of that build that had Microsoft users still attached to them?Hi!
This machine is joined to a domain? This SID with parameter "-21-" indicates a domain. If so, it is needed to verify on local polices if any user had permission on domain workstations enforced by network Administration.
But when researching by SID "S-1-14-21" we have no
reference, as parameter "-14-" is not commonly used.
From articles bellow, we can find how SID works and the well known SIDs:
http://msdn.microsoft.com/en-us/library/dd302645.aspx
http://technet.microsoft.com/en-us/library/dn743661.aspx
As this is not a known SID, I suggest you to try to use the script on link bellow to determine who is the user account:
http://blogs.technet.com/b/heyscriptingguy/archive/2004/12/03/how-can-i-determine-the-sid-for-a-user-account.aspx
The problem can be a user account that had already deleted (this is why SID is not resolved to a name) or a problem on WMI component that is not able to resolve SID.
If not successfull with article above, please post a screenshot on file permission in order to help you further.
Cheers!

V$session and v$session_longops
Hi,
in 10gR2, why SID in v$session_longops does not existe in v$session :
SQL> select SID from v$session_longops group by SID;
SID
137
SQL> select SID from v$session where SID='137';
No row selected.
Any explanation.
Many thanks.v$session_longops contains entries even for dead connections that don't exist in v$session any more.
If you want to read more about v$session_longops you can read my paper
"Long running Operations in Oracle (entries in v$session_longops)"
at http://www.gplivna.eu/papers/v$session_longops.htm
Excerpt:
Summary
There are several facts one has to remember about long running operations:
1) Not all operations that are running longer than 6 seconds are considered as long operations. Built-in long operation types are strongly defined although increasing with every new Oracle version.
2) There are some other criteria to show the particular operation type in v$session_longops.
3) Long operations of particular kind can be very different i.e. they can actually do many more things behind the scenes and one cannot find out that just looking at long operation.
4) Oracle considers long operations as linear operations (each unit of work takes the same amount of time) therefore estimated completion time can be inaccurate in case the real process is not linear.

Hi All
In BI 7.0, I am facing an error while activating the ODS. The data has been loaded successfully by the DTP. But its turning RED in the activation. When i checked the log,
the error is under SID Generation.
In data Pkt 2 : "No data can be loaded for which no masterd data exists. No SID found for value 'xx' of char 0soursystem."
In data Pkt 3 : "No data can be loaded for which no masterd data exists. No SID found for value 'xxxx' of char Zcustomer."
When i checked the data, everything looks fine. I see the master data too. So why this error comes ?
2) Why SIDs are created on activation ?
3) Is it pre-requisite to have the master data ready in the MD tables, before loading the data into ODS ? otherwise, will it fail ?
4) when can i remove the option for BEX reporting for my ODS. In BI, I dont see that option in ODS.
Any help pls ?
thx
venkatHi..............
First when we load a ODS...........first it goes to activation queue.........when we activate the ODS then only it goes to active table................DUe to this SID issue always come in time of activatio..............during data load notjing will happen...............In case of a Infocube load will fail...............
Now SID...........While creating a master data.........in the MASter data/Text tab..........if you make it master data enable...............then automatically it will linled with four tables..........
Attribute
Text
Hierarchy
SID.....................
So when we are loadind Master data SID will generate............
Here this error came because...........SID does'nt exist for that particular value...............
So first you load the master data.........if possible do full upload..........
If then also load fails............
Then go to source system..........copy the datasource of the master data IP...........go to RSA3 in the source system................Check the data source for that particuler value.........whether value exist in the source system or not..........
Hope this helps you.........

Purchased gift cards about a year ago. Misplaced two of them, but Found them yesterday. i tried to use one today. Invalid. If the money is tagged to the card code why is it invalid? Now have to take photos of both sides and find receipt? Finding the receipt might take as long as .finding the cards. If I paid hard earned money for the card from a computer company why would that card not be in their data base waiting to be activated? I guess I am out $20 to Apple for not activating immediately! My account was hacked once so I won't put a credit card in and live with gift cards. Now I am getting hit for $20, two gift cards for ten each. I now question who and how people are making money?? Is my only solution, buy card, redeem code instantly, purchase item?

For Example: like this makes no sense. is it because it wasnt purchased directly from itunes? If so thats ridiculous. I've had an iphone for over a year, and a macbook for over 2 years. my phone is completley updated to 7.0.3 and my computer is completley updated with the new itunes 11.1.12 which i thought was supposed to help this problem. I've never had this problem, and its extremely frustrating.
I downloaded one of the file explorer programs (iFunbox in my case) for my PC and deleted everything out of the "Purchases" folder on the phone's "Raw File System". After a couple of syncs with iTunes everything was back to normal. It appears that something was screwed up on the iPhone side that iTunes couldn't sort out. I don't think anything could sync from iTunes to the phone, not just the greyed out items.
This is why resetting and restoring the iPhone also works for a lot of people. It's overkill though, deletes your app data, and just wastes your time setting everything back up after the restore. Better to use the surgical approach of a file system explorer program on your PC to fix what appears to be a mundane data corruption issue. -
i have scenario SOAP to IDOC
when i'm using business service in sender side it is getting an error as follows
sender message can not convert to ALE Logical system
in this i'm using altova spy as testing tool
my sender interface is asynchronous
but when i'm using business system everything is working fine
In sender side i'm using soap adapter,i checked the logical system everything is fine
mainly the problem is why it is working when i'm using business system rather than business service
my pi version is pi 7.0
thanks in advance
regards
satishHi Satish,
You are sending IDOC's to SAP system right. we should create Business system not business service.
so we should create the business system as web AS ABAP in SLD and import the same in ID.
When we create the business system in SLD the logical system name is assigned for the business system. like SAPCLNT100...It plays a key role in IDOC scenarios.
sender message can not convert to ALE Logical system
Reasons for this issue is
1) logical system name is unable to read from SLD for that corresponding business system.
Goto business system click on Adapter specific identifiers from the menu --> read from SLD.
it will automatically fetch the logical system name from the SLD.
2) Sometimes the logical system name will be deleted from the business system in SLD.
Delete the business system and re-create it, and follow the above procedure.it will resolve your issue.

Here is my site for you to see what I am talking about; http://www.minkstereo.com after you enter, if you go to each of the menus you will notice that only Books and Ilustrations is named correctly in the tab, if you go to Drawings, Graphic Design, Crafts or any of the images you'll see that the page name is "About me" I have republished and check all over the page in iweb and I don't know why it is happening. Each page has a different name in accordance with the content both in the side bar and in the inspector it shows.
Any help is appreciated thank you.Your images shows how to change the pagename, the filename. of the page.
Not the browser title.
Anyway, there is a textbox out of view that holds the title :
Beats me what it is doing there, but here is the oft repeated explanation :
iWeb uses the textbox in the Header layer of an iWeb page as the title in the browserwindow.
If the textbox in the Header is missing, iWeb uses a textbox down the page in the Content layer. If that textbox is also missing, it uses another textbox. If that fails it uses the pagename in the Sidebar. To replace a missing textbox in the Header, choose another theme and then change it back to the original one.
Sometimes you may want a different text in the titlebar and not display it on the page itself. Or not display it at all.
So use that textbox in the Header layer. Type your text. Do Command-T to open the font palette and make the font smaller (Or do Command--(minus)). Then select the textbox. In the Inspector choose T, click a color to open the color palette and drag the opacity slider to 0 (zero).
Resize the textbox. You may want to change the height of the Header layer.
Do Command-Shift-B to move the textbox to the back, possibly behind other objects.
Next add a optional second textbox to the Header layer and use that one to display text on the page.
If you want to move the textbox to the front again to make changes, but can't remember the location on the page, drag the area with the mouse to select the objects.
Deselect objects you do not want to move forward by Command-dragging the mouse over these objects.
Next do Command-Shift-F to move the textbox to the front. Repeat the steps in reverse order to make the text visible.

Printing with In Design CS4 only print left side,why?
How do I print a document in Design (CS4). I have a 11x17 document (landscape) and when I send it to print it only print the left side (letter). It is a newsletter so one 11x17 comprises 2 letter size pages. I want to print them all but page by page by letter size only so we can proof read.
I noticed that in the preview you can see only the half left side is highligthed for printing. I tried to play around and Icouldn't.
Do you know why?.
Also when you send a document for the printing services, do you send in in 11x17 size? or letter size?
It is a 6 page newsletter. One 11x17 both side = 4 pages and One insert 8.5 x11 both sides = 2 pages
Thanks,If your page is set up as 11 x 17 and you try to print to letter-size paper yoou'll need to enable tiling to get both sides.
The correct way to set this file up is as lettersize facing pages (and they should be set in consecutive order, as the reader will see them). Imposition for printing is done at print time. If you are required to provide the imposed spreads (and no printer worth their salt should be asking for this), you can place the pages from the original file into a new 11 x 17 document in the correct order. Your insert will probably also print as 11 x 17, just half as many sheets with two copies per sheet, then get cut apart and inserted.
