How delta is handled ?

Hi,
We have used BPC methodology to load data from BI cube to BPC application.
now what happens when we load the data from bi cube to Bpc application(assuming we have done one full load for the first time ) does it read all the data from the BI cube and then do manipulation for the subsequent loads or does it read only the delta records that were loaded since the last load and then load the data into BPC application ?
if it reads all the data then what if the volumes are high ? does it not lead to performance bottle neck over a period of time ?
how this is handled in other projects ?
ideas/thoughts appreciated.
Regards

Hi D,
Good to see a concrete answer from you saying "Delta is not possible".
This would help me to look after other options rather than scratching my head trying to find out whether or not !!!!
But the option of using a variable still remains unanswered ?
a dynamic way of selecting the month of load in SELECTION may solve the problem temporarily until a rescue is planned in ver 7.5
does any one used SELECTION to handle delta ?
Regards

In BI 7 how do we handle if any delta load gets fails

Hello All
Iam having a doubt like,in BW 3.5 if we are loading delta data from one source ODS to 2 targets(either cube or ODS),and if for one target if the load gets failed we will delete the bad request from the 2 target ods , reomve datamart flag from source ods and then relaod the delta load again.
But in BI 7 how do we handle this type of scenarios.
Many Thanks
Swami

In 7.0 we have DTP between one source and one target right?
If a load fails then delete the concerned request and reload.
It is independent of the other load.

Interview Q: 'how did you handle delta'

Hi BW experts,
I've been asked this question in the interviews, 'how did you handle delta?' I know how to create delta. What is the right answer for this type of question? should I start explaining what/how we did in my previous company?
I'd appreciate and assign points, if someone can provide the answer for this.
Thanks,
Sam

The answer depends on what you have been talking about, I mean the previous discussion you had with the the interviewer. There are different way of handling delta... example:
1. The extractor itself handles delta and it send you the before and after image of the changes.
2. sometimes you load the data direclty to ODS and depending on the key you have in ods, the delta is being handled.
3. In somecases, you may not need to worry about handling delta at all (full load)... going back to the quesion you asked, that depends on the discussion you had with him/her.
thanks.

Time Machine - how does it handle a full disc when increments are deleted?

I have a 500G.
I could not find any info on the following, so would greatly appreciate help.
My understanding of how it works is
- there is an initial backup - FULL (step0)
- the next steps are incremental i.e.
- step 1 is a delta between the state at the time and step0
- step 2 is the difference between the state at the time and step1
- etc
The questions are the following
1) will there ever be another FULL backup? or all are from step0 on incremental?
2) if the disk is full, what will be deleted?
2a) if an intermediate step is deleted how will the TIme Machine build the next step??
3) if I need to recover/restore, will it start from step0 and then apply step1, step2, step3, etc till it is complete?
3a) if this is the case, how are "deletions" handled, in case there is no more disc space (previous question)
many TIA!
luis

luissimoes, Welcome to the discussion area!
These are really Time Machine questions not Time Capsule questions.
1) will there ever be another FULL backup? or all are from step0 on incremental?
No and yes.
2) if the disk is full, what will be deleted?
From what I understand (and I could be wrong)...
The files deleted from the source drive starting with the earliest ones deleted. i.e. files deleted on Jan 1 will be removed from the backup before those deleted on Jan 2.
After the deleted files have been removed. The oldest versions of files with multiple versions will be deleted.
2a) if an intermediate step is deleted how will the TIme Machine build the next step??
A complete intermediate step would only be deleted if all the files involved had been deleted from the source drive or newer versions of those files were already backed up.
3) if I need to recover/restore, will it start from step0 and then apply step1, step2, step3, etc till it is complete?
Doubtful. That would be horribly inefficient even if nothing was ever removed from the Time Machine backup.

How delta works in HANA

Hi All
Can anybody explain how the delta mechanism works in HANA,to be precise if there are any changes to the existing records how they are handled .How HANA classifies the current information and past information.
Thanks for your inputs.

Hello Santosh,
in the column store all modifications of data are written to the delta log of the table first.
If rows from the main storage (called "main index") have been changed or deleted, then these main index entries are made invisible to other transactions (the multiversion concurrency does this visibility handling of data) and the data from the delta log is used thereof.
Once the delta and main indexes get merged, the old main index entry will be removed and only the current version of the row will be present.
This is out it works for common column tables.
If you use "history"-tables, then the old versions of the rows are never actually removed but made (in-)visible depending on the timestamp from when these rows have been inserted first.
This is as much as I can tell about this. For more information on this topic, please consider joining the HANA core development team

Lars

How is IPC handled in CRM5.0

Hi experts,
Can any one plz let me know how is IPC handled in CRM 5.0??????
I mean is there any difference how we handled IPC between CRM 4.0 and CRM 5.0??? or is the same way as we handle in CRM 4.0?????
Can any one please let me know in detail????
your inputs will be highly rewarded.
Thanks in advance,
Regards,
DV.

DV,
Take a look at the following link in service marketplace:
http://service.sap.com/~form/sapnet?_SCENARIO=01100035870000000202&_SHORTKEY=01100035870000429833
You will find the release notes for SAP CRM located there. That will will give a detailed overview of what has been changed in SAP CRM for each release. All you need is an SAP service marketplace id, which should be no problem if you are a SAP customer or partner, or working at an SAP customer site.
That would be my best source. You could also purchase(if you don't already own), the RKT materials for CRM 5.0 from SAP education. An excellent reference for delta changes between CRM 4.0 and CRM 5.0.
Take care,
Stephen

How delta work in BI

Hi
Can anyone help on how the logic handle of delta in BI?
Example:
1) Create Purchase Order with PO qty 10 on 01/11/2008 in R3.
    Result: Purchase Order with PO qty 10 send to BI
2) On 10/11/2008, there is change on PO qty from 10 to 9 in R3.
    Result-1: Will BI delete the record for PO with qty 10 that was send to BI previously? Follow by insert the latest change for PO with qty 9 to BI?
<OR>   Result-2: Purchase order with PO qty 10 is remain in BI. Besides, there is delta send to BI for Purchase order with PO qty = 1?
What is the possible result. Please advice.
Thanks,
Kang Ring

Hi.....
There are two record modes for Delta.....After image(new records) and Before image(Old records)....
1) Create Purchase Order with PO qty 10 on 01/11/2008 in R3.
Result: Purchase Order with PO qty 10 send to BI
2) On 10/11/2008, there is change on PO qty from 10 to 9 in R3
If its a Infocube . i.e it is additive so we can send the before image and the after image together......additive image (A)....where old record is added with KF inverted, and new records added as it is.
then....
PO qty
10
-9
If its a ODS.......we can send the after image(' ').......since overwrite optionis there.......
then..
PO qty
9
Another type is New image (N).........it only sends the new records........so data can loaded to ODS only.........in the type of delta.....
Another is Reverse image (R).......The content of this record is the same as the content of a before image. The only difference is with an ODS object update: Existing records with the same key are deleted.
You can find all the details in the table RODELTAM....just go to that table through se16......there you will get all the details.....just press F1 in any fields......
Hope this helps.....
Regards,
Debjani......

How do I handle my Final SELECT based on a @ReportType Run Parameter

So I have multiple CTEs in my SQL...
WITH CTE_1 AS
(SELECT...)
CTE_2 AS
(SELECT...)
CTE_3 AS
(SELECT...)
My Final SELECT then will be based on my CTE drill-downs and the filtering will be based on the @ReportType that will be chosen within SSRS and Report Manager. How can I handle the varying portions of my FINAL SELECT based on @ReportType? Do I have to do
this via dynamic SQL? I know that dynamic SQL is frowned upon. So this is what I'm talking about...
SELECT ...
CASE WHEN @ReportType = 'Renewal People'
THEN INNER JOIN...
WHEN @ReportType = 'New People'
THEN NOT IN (SELECT...)
END
CASE WHEN @ReportType = 'Renewal People'
THEN WHERE...
WHEN @ReportType = 'New People'
THEN WHERE...
END

> I know that dynamic SQL is frowned upon.
That depends. I love (*) dynamic SQL for one thing:
http://www.sqlusa.com/bestpractices/dynamicsql/
Second, there are many things you cannot in static SQL:
http://www.sqlusa.com/bestpractices2008/rebuild-all-indexes/
* First choice is static SQL always.

How do you handle multiple at the same address?

My wife just got an iMac. She is using the Birthday feature in Address Book and iCal to track our friends and family birthdays and anniversaries.
Question:
How do you track it when multiple people are at the same address? For instance, our friends are a family of four, but they all live at the same address. Do you need to make a separate Address Book card for each of them, even the 1 year old baby? Or can you track multiple people in a single card with custom fields?
If you do need to make multiple cards, then how do you handle mailing lists? For instance, if I make separate cards for all four of them, how do I make sure I only send on Christmas card when I use my Mac to print labels?
Thanks for any advice.

This is really an issue that you're going to have to resolve yourself since Apple's address book isn't really built with this in mind - darn it. For me there are three scenarios. First, a singleton. No problem. Second a family for which all members share the same information - acquantences to whom I don't send birthday greetings. These get one card and I'll put in both (or all) their names in the first name field (as in Bob and Jean). If there are children, in the last name field I'll add 'and Ken' or 'and the kids'. Third, a family for which some fields are different - perhaps cell phone number, birthday, etc.
For mailing purposes, I create a holiday group and put the people I'll be sending cards to into the group.

How does IITTrackCollection handle ItemByName if there are multiple tracks by the same name?

I am writing a program in C# that is trying to check if a track already exists in the iTunes Library before adding it (thus preventing duplicates). The best method I have come up to do this with is to use 'MyPlaylist.ItemByName(SongName)' to retrieve a possible duplicate and then compare the rest of that track's attributes (i.e. the artist and album). However, I have several examples of tracks in my library which have the exact same name, but are in fact completely different and unrelated. How is this handled by the iTunes COM? Or is there a better way to do it?

Hi DSW,
Thanks for your post.
In your query result, please check if these two users have the same Account Name. if they are two different Account Name in result, it indicate there’s two users have the same display name in your AD, please check that two users’ information in
your AD. We suggest change one user’s display name in AD.

How can we handle browser settings while dealing with the security ?

Hi ,
how can we handle browser settings while dealing with the security ?When we configured security in web.xml , during the first request the container is asking for the authentication credentials once they are provided it go's on. but when the user gives a fresh request from the second window within the same browser that time it is not asking for authentication. How can we overcome this.Is there anything to do with server configurations?
How can we make the container no to keep the things or act like session?

Ya... I am taking a small example need not happen always but a kind of possibility i am thinking off.
once the user sign out and just left without closing the browser and a friend (suppose not a good friend ... just kidding...) of that user may open the same jsp or file .This time the security is breached. If that feature or property exists....
I know what you might say ... the user will log-out before leaving where a programer might invalidate the session at the time of log out.
Consider the case of a bad Programing or just a programer might forget to invalidate,At that time as a application administrator how can he solve that issue.
Thanks.......

How best to handle multiple web sites using iWeb 08

I currently am using iWeb08. I am maintaining two websites; The church site resides on a Rogers server. I use Transmit as a FTP loader. The other site is an engineering society's website that is posted on Apple's server. I have an ME account just for the latter group. iWebsites is used to alternate between the two sites. The church group has a .ca web address.
Is it worth upgrading to iWeb 09? How does iWeb09 handle 2 websites? I wish I could publish both to the Mac account but have not figured out how. I must retain the rogers account for viewing the church site
Has anyone deleted iWebsites from OX10.5.6? How was it done? I know that backups are mandatory before attempting these changes.
Thanks,
Bill

In its current form, iWeb '09 doesn't handle publishing well at all!
I keep all my sites on separate domain files, each in their own folder. Any site is launched in iWeb by double clicking the domain file. I start each new site from a new, blank domain file.
I keep all my website folders in a folder in a second dock so that I can launch any site with two mouse clicks - faster than you can launch iWebsites!
You can publish as many sites as you want to one MobileMe account but you can only have domain name forwarded as Cname. Any more have to use masking with all its inherent problems.
I would be more inclined to dump MobileMe and publish both sites to a decent hosting company.
The new iWeb '09 FTP works for some. I have tested it with my server - Host Excellence - which doesn't force you to upload to a Public_html folder and this goes as planned.
Having said that, I still publish to a local folder as I optimize and upload my files using Web Site Maestro. Once you have published your site for the first time, this application will then use its Smart Handling feature to process the changed files only.
Unless all your viewers use Macs you have to optimize to get your pages to download in that browser that all the Fred Flintstones of the world use.

How do you handle an incoming call while playing a game?

If you're playing a game on your iPhone, how do you handle an incoming call? A call will stop my app from running, but how do I save the state and restore it when the user starts the app again?
I have a bunch of objects on-screen and I need to record where they are so that the user doesn't lose the progress of their game.
I've looked through the SDK, but I can't see anything obvious. Any ideas?

I don't have a device to test with, but I suspect you'd want to save state in one of the UIApplicationDelegate callbacks:
applicationWillResignActive:
applicationWillTerminate:
