Solution on Data Handling

Hi All,
I am lookin for some idea of modelling on BW.
The requirement is to have the information on weekly basis (Current Week or History week)
Now, the solution was to copy unchanged data as well to the current week.
This was helping to have a week basis snapshot in the cube.
But off late we got to know that the data is huge and copying will eat time
Is there any way we could avoid copying?
Hope I am clear.
Thanks In Advance

I've managed to override the dispatchEvent method when
extending the HTTPService, and it looks like that could be the way
forward. At the moment I've got it checking to see if the event
it's dispatching is a result event and if so then I'm doing my
stuff and changing that event to my custom one.
Question now is, there will be many of these custom
HTTPServices allover my application and I want to be able to dump
any CakeDebug I get in the response to a central location in the
application --- what would be the best way to do that (without
passing round the CakeDebugManager -- or whatever I create). I
can't have the CakeDebugManager add a listener to every HTTPService
as I'll need a reference to the HTTPService and that will break my
encapsulation.
As I say, I'm still new to Flex.

Plan data handling profile

Dear Gurus,
There is a customzing point under Project System -> Costs -> Planned Costs -> Maintain plan data handling profile.
Does anyone have any idea about:
- where can it be used?
- what is it used for?
I was looking for any tool which makes plan figures on WBS elements out of purchase orders and I found this but there is no info at all, no where.
Thanks in advance,
Jeno

This profile is aimed to be used in transaction AD31 (and associated Tcode AD32). Those belongs to an add-on of IS A&D solution.
The purpose is to provide a functionality to calculate the plan cost at completion by adding the actuals costs (including or not the commitments form PO and/or PR) to the cost to complete entered in a specific planning version.
This functionality can also be used to calculate the cost to complete by calculating the difference between the plan costs at completion stored on a dedicated planning version, and actuals costs (including or not the commitments form PO and/or PR).
As SAP provides, independently, the possibility to copy actual to plan, the profile gives the flexibility to calculate the cost to complete by adding 2 planning versions.

Data handling issue

The problem is that my application receives sterilized java object in zip format from third party system then my application can update into DB2 tables in a given time frame (max 1 min). This results into a buffer overflows which implies that data are discarded due to buffer size limit. Every min, my application receives the data from third party.
At present, application data handling is implemented in queuing mechanism. Application expected to handle 100000 java objects per min. Do you have any idea to implement the solution for above issue.
At present I have an idea to implement virtual table (array list) and keep the data into memory..use it after 1 min. required your valuable input.

Question: What is a "sterilized" object? I'm familiar with several euphemisms, but that's a new one on me.
This for nothing:
1. Simply reading 100,000 objects could take a reasonable percentage of your 1 minute, let alone marshalling and then sending them to a database for update. This suggests to me that your solution isn't scalable.
2. Buffer overflows (if that's indeed what it is; you haven't supplied an exception) are a result of bad programming. Find the bug, and fix it.

Receiving a DNS Solution Yahoo Error Handler Page and some pages won't display

I recently downloaded the Stuffit Expander and ever since then Firefox hasn't been the same. I receive a DNS Solution Yahoo Error Handler page when I do a search sometimes. And now some pages won't even display for me when they should. How do I get rid of this Yahoo thing (In simple terms please)? Thanks!

Mass data handling in an Enterprise SOA

Hello together,
i'm working on my diploma thesis with the title "Design of a service-oriented architecture based on SAP NetWeaver".
For this work an enterprise service is designed to calculate a special price matrix (10x5) from a given price for a product.
Additionally the matrix for a product can have four variations, depending from input values. I think for few products there's no problem.
But it's also possible that someone wants to export the price matrices for all 15.000 products. So there are 60.000 (4 x 15.000) service requests at once.
So my questions:
Is it (without bigger problems) possible for a service to handle so many requests at one time? Or generally, how behaves enterprise SOA in cases of mass data requests like that (network traffic, workload, overhead for enterprise services...)?
An alternative is to storage all matrices in a DB (would be much redundancy, because variations of the matrices are very similar).
Thanks for any answers
Joschi

Having the same service to get one product price as well as all product prices would not be recommended. Two separate services would be more reasonable
Mass data handling in SOA is not entirely different than let's say in BAPI/RFC environment. parallelism, multi-threading, locking, commit and many others are typical elements of considerations.
From a scalability standpoint, you can always be interested in how optimal its performance is whether you call it once or a million times. If the service is a rather slim one (lightweight in terms of number and types of parameters as well as processing code), you'll surely have better chance than with a service that's heavyweight.

Screen data handling in Screen Enhancement with BAdI's ?

Hi all,
I'm trying to build a Screen Enhancement with (new) BAdI concept.
But now I'm having a Problem. The new BAdI's don't allow variable Attributes (instance/static attribute) in the BAdI Interface.
If I try to define an instance or static Attribute for the BAdI-Interface I get the following error message:
"BAdI interface <my_badi_if> contains non-constant attributes "
In my Screen Enhancement I have build a Subscreen with new fields in it. These field data couldn't be saved in the BAdI class (e.g. via BAdI-methods my_badi->get_data_from_screen... and my_badi->put_data_on_screen...) because having no attributes.
How these screen-data could be handled without BAdI-Interface-Attributes?
Thanks in advance,
Anja

Error -2003: a data handler needed by the movie could not be found

Hello.
I just purchased QuickTime Pro and the MPEG-2 add-on for it, for the single purpose of transcoding some MPEG-2 recordings to H.264. However, when I try to open any of my MPEG-2 files in Quicktime, I get the message: "error -2003: a data handler needed by the movie could not be found (my-filename.mpg)"
I can play these files in a number of different free players--VLC, Mplayer, Windows Media Player, RealPlayer... but not in the player I paid $50 for.
Can someone please help me?

That doesn't really help. Besides, I haven't even got to the point where I'm trying to export. I get this error message when I try to open the file. I can't even play back the clip.
And the MPEG-2 page clearly states: "The QuickTime MPEG-2 Playback Component provides QuickTime users with the ability to import and play back MPEG-2 content, including both multiplexed (a.k.a. muxed, where the audio and video tracks are interleaved together into one track) and non-multiplexed (a.k.a. elementary) streams."
Also, Streamclip crashes when I try to load my MPEG-2 clips, so that's not going to work (and even if it did, I am trying to find a simple way to take the HDTV content I've recorded off the air and get it onto my AppleTV--I want fewer steps, not more).
Looks like I'll have to waste some time calling customer service to get a refund, since there's no way to do this via the website.

How is table control data handled in Session Method?

Hi Friends,
Can any1 plz tell me how is table control data handled in Session Method.
In Call tran we do it by count. But how in Session Method?
Thank you.
Regards,
Varun.

Hi,
u can do it by both methods. u can check out this program. u need to comment the performs of table control fields and write ur own perform statements.And u have to declare the table control fields as separate internal tables.

SRM7.0 Meta Data Handling or Component Configuration

Hi Experts!
Let's say you for some reaseon want to remove the a field in the Shopping Cart at item level. To achieve this you could e.g.
1. Use the Component Configurator (SE80) - and use the browser-based Editor for the WDP ABAP Component Configurator
2. Use the Meta Data Handling Concept and configure the field control there
My guess is that one should use #2 if one need to control the behaviour of the field according to roles or authorities, but is this correct, or are there other considerations that should be taken into account when performing UI adjustments using the above mentioned methods?

US to UK Date Handling

Hi all,
Is it possible to set up date handling in Project Siena so it recognises Date input as dd/mm/yy instead of the US mm/dd/yy.

just format a date in whatever format you like with Text function
Example
Text(Today(),"dd/mm/yy") 03/11/14
Text(Today(),"dd/mmmm/yy") 03/November/14
Check this page out for all function
http://technet.microsoft.com/library/dn690139
And for date inputs is much more better to create own date picker. Here is a link to one of them

What are the best solutions for data warehouse configuration in 10gR2

I need help on solutions to be provided to my Client for upgrading the data warehouse.
Current Configuration: Oracle database 9.2.0.8. This database contains the data warehouse and one more data mart on the same host.Sizes are respectively 6 Terabyte(retention policy of 3 years+current year) and 1 Terabyte. The ETL tool and BO Reporting tools are also hosted on the same host. This current configuration is really performing poor.
Client cannot go for a major architectural or configuration changes to its existing environment now due to some constraints.
However, they have agreed to separate out the databases on separate hosts from the ETL tools and BO objects. Also we are planning to upgrade the database to 10gR2 to attain stability, better performance and overcome current headaches.
We cannot upgrade the database to 11g as the BO is at a version 6.5 which isn't compatible with Oracle 11g. And Client cannot afford to upgrade anything else other than the database.
So, my role is very vital in providing a perfect solution towards better performance and take a successful migration of Oracle Database from one host to another (similar platform and OS) in addition to upgrade.
I have till now thought of the following:
Move the Oracle database and data mart to separate host.
The host will be the same platform, that is, HP Superdome with HP-UX 32-bit OS (we cannot change to 64-bit as ETL tool doesn't support)
Install new Oracle database 10g on the new host and move the data to it.
Exploring all new features of 10gR2 to help data warehouse, that is, SQL MODEL Clause introduction, Parallel processing, Partitioning, Data Pump, SPA to study pre and post migrations.
Also thinking of RAC to provide more better solution as our main motive is to show a tremendous performance enhancement.
I need all your help to prepare a good road map for my assignment. Please suggest.
Thanks,
Tapan

Data Handler source code need modification

I found this in the forum and try to implement it in my page. The code is running okay but just that when I first load the page into the browser, It shows ALL the records in the database beneath the searchbox.
All I want is first time user come to the page, it only show the search box but no result. And after user enter the data, it then performs the search and show the result beneath.

A couple of years ago Sun supplied their javax.comm package (mysteriously versioned as version 2)
but they stopped it for the PC Windows.
There's an alternative: rxtx which offers an identical API as Sun did and their own native implementation for serial and parallel port handling; I have used both and the rxtx version is clearly superior to Sun's old version: http://www.rxtx.org
This question popped up recently.

Problem with apply changes on master-detail with respect to date handling

dear sir,
i have one tabler where in i have created from_Date and to_date as varchar2(30) each. I stored the from date as 'dd-mon-yyyy hh24:mi' I had written before header process for calculating no of days between from_Date and to_Date using the said format. If to_Date is null then first i store the value as
to_char(sysdate,'dd-mon-yyyy hh24:mi') and then convert it as to_Date(substr(to_Date,1,17),'dd-mon-yyyy hh24:mi'). this calculation of days procedures works fine in sql command mode.
when i am handling through master-detail page i works fine when there is null value inf to_Date vc2 column. if i store using date picker dd-mon-yyyy hh24:mi, the data is getting stored but subsequent edit through master detail give error as ora-01722 unable to fetch row. Manually if i set the to_Date as null pages works fine. I spent lots of time and unable to understand the mistake i do.
if anybody could help me, i will be much obliged.
thanking you,
yours

I think the best would be if you create an example on apex.oracle.com and I will debug it.

Date handling change w/upgrade

Raj,
Hope all is well, I upgraded from htmldb 1.38 to 1.4.0.00.21c
Noticed dates are acting different...
Here is just one example...Before the upgrade, I had a validation function that worked
begin
if :P15_SDATE < sysdate - 10950
or :P15_EDATE < sysdate - 10950
or :p15_sdate > :P15_edate
then return false;
else
return true;
end if;
end;
after the upgrade it did not work, and returned invalid month errors....
The :p15_sdate and :p15_edate are date pickers in my native format (mm/dd/yyyy)...
After the upgrade it only worked if I changed the code and did a
to_date(:p15_sdate ,'MM/DD/YYYY')
and this is fine (I know I should be comparing dates to dates and already fixed the code)...but wondering if you know about this, why the change...and am I missing something I should/could be doing to make it better.
Thanks,
Meyer

though i'm pretty sure we've made no code changes to the way dates are handled in html db by default, there's a small chance that we're doing a better job of picking up the correct nls settings as determined by the Globalization options available on the application-level attributes page. to be honest, my hunch/hope is that you changed that "Application Language Derived From" attribute from the default "No NLS (Application not translated)" to "Browser (use browser language preference)". if your app's set to that "Browser (use browser language preference)", your nls_date_format will be set to the standard for your current language (in your case i'd guess that'd be en-us and dd-mon-yy, respectively). if your "Application Language Derived From" attribute is set "No NLS (Application not translated)", then we'd be using the nls_date_format of our database. so, assuming the date format of your db truly is 'MM/DD/YYYY' and your app is set up to provide no NLS support, i'm pretty sure you'd find that having a pl/sql region on a page in your app that did a...
htp.p (sysdate);
...would return something like...
10/01/2003
...if you then change your "Application Language Derived From" attribute to "Browser (use browser language preference)" and accessed your app from a browser using a primary language of "en-us" you'd find your pl/sql region returned a...
01-OCT-03
...or at least that's my take on this stuff. i'm pretty sure i'm on the right track, though. again, after talking to our development manager about this, i'm rather sure that nothing's changed on our part (with respect to default intended functionality). though there's the off chance that we're doing a better job of paying attention to your globalization prefs., my hope is that the prefs in your app have changed since you originally coded those pages.
hope this helps,
raj
