What is data selection? how does it work in sap bi?

details about data selection process

Hi Nihar,
1. Data in SAP comes from different sources .
2. Sometime we have generalize data from which we need specific data based on our reporting requirement .
ex: If data is coming from standard extractor etc then it is generalized for various reports .If you have specific requirement then you don't need all the data to be loaded in DSO and Cubes .
3.Sometime there is huge amount of data so we select data as per our requirement ex :yearly ,Quarterly ,Fiscal period wise ,Company code wise etc .
4.We can filter out useful data at different level like :
At info package level ,at DTP level ,By routines in transformation ,By using filters at queries etc .
The whole purpose of selection is to load only useful data for reporting .It is part of process of cleansing of data before loading in a Warehouse .

What is efax and how does it work?

Hi!
eFax® is a service provided by eFax®, not Hewlett-Packard, that allows you to send and receive faxes using the Internet rather than a phone line. eFax® is easy to use, but it is different than a typical phone-based fax machine. You don't require a phone line to use it, so you don't have to worry about busy signals and you can place your printer where you want it, not where the phone jacks are located! The fax number you are provided will not typically be a local number, and may even be in a different country. You will receive 20 incoming and 20 outgoing fax pages per month for free with this service. Your page counts will reset at midnight Pacific Time on the first of each month. You can also subscribe to eFax® Plus to obtain additional pages per month by visiting: http://www.eFax.com/products/internet-fax.
How does it work?
eFax® uses the printer Internet connection to send and receive faxes. When you send a fax, it is sent over the Internet to the eFax® server and then eFax® sends your fax to the recipient's fax machine over a standard phone line.
Your faxes are received in a similar manner, but the order is reversed. The sender sends the fax over a phone line to eFax® and then eFax® sends the fax to your printer using HP's ePrint service.

Hi Im_cheesecake,
Great information, if you don't mind I just wanted to piggy back off of your post, to clear any potential confusion.
The 20 free incoming & 20 free outgoing faxes are with HP printer's that include the eFax service print app. As of now, we have three printer series' that include the pre-installed eFax print app: HP Photosmart 7510 Series, HP Envy 110 Series, and the HP Photosmart eStation C510a.
eFax also has a free plan which allows you to receive a limited number of faxes but does not allow you to send any faxes. If you exceed the number of received faxes allowed, eFax will prompt you to upgrade to a paying account. Here are the main details of the free plan:
One remote (i.e. non-local) eFax number
Area code/prefix is selected by eFax and cannot be changed (unless you upgrade to a paid account)
20 incoming fax pages per month (receive-only)
You are prompted to upgrade to a paying account if you exceed 20 incoming pages, or if you need send capability.

Menu Object; MANUAL option. What is this, and how does it work?

What is this... and, how does it work? Can't find documentation on this.

My knee-jerk reaction is, "are f'n kidding me?"... but, of course, you're not.
I must say, that is an incredibly useless option. How would that 'option" differ from simply making a text object (or text/rectangle/image combo or group) and creating a link?
What got me looking at this option was the hope to find some way to insert a dynamic "field" that could be used on a master page to display the current page title (of a page based on that master). Something similar to Word (and other applications) that you can enter information into a document property and then insert that information anywhere within the document by using a field code for that info. I don't know if there is an HTML code that could be used to accomplish this, in this case. Something that would refer to the page title.
Thanks for the info none-the-less.

What is persistence? How does it work?

Hi,
I'm a total noob. I've been reading and following examples from books but I haven't read anything about how persistence really works? How does it help my session beans to access or make transactions to the database? How does it actually work? What if I just make direct queries from my session beans without the help of the EntityManager or the Peristence API? What's the difference?
Like this for example:
Customer requestCustomer = em.find(Customer.class.customerId);Does it mean that the Persistence API keeps the object alive in the Customer Entity? For how long? Until the application is closed? If so, what happens if the user opens the application again and looks for that object?
Why can't I just make a direct query to see if that customerId exists in the database?
I hope you guys don't mind my questions... I just really want to learn this stuff and I gotta let things out of my head. Hope you can help. Thanks!

You have to code the stuff that EntityManager and Persistence are doing for you.
Like this for example:
Customer requestCustomer = em.find(Customer.class.customerId);Does it mean that the Persistence API keeps the object alive in the Customer Entity? For how long? Until the application is closed? Complicated. Not enough info.
If so, what happens if the user opens the application again and looks for that object?
Open the app and the object will be refreshed from that data store. Hence the word "persistent".
Why can't I just make a direct query to see if that customerId exists in the database?
You can.
I hope you guys don't mind my questions... I just really want to learn this stuff and I gotta let things out of my head. Hope you can help. Thanks!This isn't the way to do it, but it's a start.

Appletalk, what is it and how does it work?

Can someone explain how Appletalk works? I have a printer at work that can use Appletalk,but the zones and all that, I dont understand.
Thanks
Nana

You don't need to create/edit zones unless the network you're on is based on AppleTalk. AppleTalk can pretty much automatically configure itself. It's only when it was part of a much bigger network that zones made it easier to deal with only Macs and devices local to you and not have to sift through every single thing on the network all over a business or school network.
What printer is this? Is the printer on a network? Does it have an Ethernet interface? An issue with older AppleTalk-compatible devices is that they only use the classic AppleTalk. Some routers will not forward AppleTalk packets. Newer Macs make use of AppleTalk over IP to run on modern networks not based on AppleTalk.

What is IMIP and how does it work with iCal? (I don't mean IMAP ! ! )

My POP email protocol includes a special folder called IMIP. This stores all emails that have "calendar" related material or invitations. However, they don't download to my MAIL application... they just stay on the MAIL SERVER in a folder called IMIP. How can I integrate this with MAIL?

Group MMS- what is it and how does it work?

I'm rarely one to ask questions about the iphone but I got my iphone 4G and today realized there was a setting that says group mms. I turned it on. I sent a text message to two people, expecting their replies to appear in the same window but they came as seperate relies. Was I wrong in assuming group mms meant replies from multiples would appear in the same window as the sent message? Please explain what Group MMS is and how it works. Thanks!

Glad to help. One thing to add...
First, in my example, I missed something...when Person B asked if someone could purchase his ticket, obviously he doesn't get his own text back to himself. I was rush typing that response, so just typed A through E, and didn't think of that, haha.
Funny enough, this is the exact situation that made me realize what the group messaging was. I was beta testing the 4.0 Golden Master, and turned that feature on, thinking that I could go to my contacts and multiselect contacts, instead of adding them one by one from the messaging app. When my friends and I made plans for a movie, I had forgotten to turn this feature off, and everyone was having a grand old time chatting with each other, via this feature on my phone.
After realizing what was going on, and some more testing to confirm accurate results, I found a slight use to this feature. Kind of cool, but can be a pain that you can turn it on "on the fly", and have to dig through the menus to enable it. Would also be much better to assign the feature to specific text threads, instead of having it apply to all group texts. I usually have a group thread going to inform my friends of free apps, and occasionally group message when coordinating. Don't need it enabled for the free apps thread, but no way to keep it on for one, but off for the other. Oh well...
Oh, and if anyone was wondering, I was Person A and Person E, haha.
EDIT: Second fail in my post was that you have to have the feature enabled BEFORE you send your group text out. Oh well, this stuff happens when the coffee shop person is on my neck, telling me that I cannot have anymore donuts, and that I must leave the vicinity. ;-D

Airport Express: Gateway: What is the # and how does it work for wirelesstv

I just purchased a Samsung 8000 series tv. It has wireless capability. For whatever reason it will not set up automatically. I've entered all of my airport express info into the tv, but when it tests the connection, it fails. It states that it cannot connect to the Gateway. Where do I find the proper Gateway code? There are four boxes like xxx-xxx-xxx-xxx on the setup menu. Thanks!

Words,
You posted in the AirPort Extreme forum but mention that you have an AirPort Express. Which do you have?
Can you tell us whether you are trying to connect to the Samsung using an ethernet connection (recommended if you want to download movies) or via wireless?
Almost all Audio/Video devices will connect automatically when they have an internet connection. You should not need to provide manual setup details unless you have an unusual configuration on your network.
If you are trying to connect using wireless, you will need to have Samsung's wireless adapter for your monitor. Do you have this device?

What is 'mobile account' and how does it work?

This is a hidden feature in Mac OS Leopard, that I believe require an Leopard Server on the network.
I have not found it in the regular user interface, but it can be revealed by following the below process:
1. Go to System Preferences > Accounts
2. Unlock
3. Search for mobile account, and press Enter
4. Wait for the Mobile account options to show up
What is this feature? How does it work?
I have found no references to it in the normal documentation.

Google is your friend:
"A mobile account is a Mac OS X Server user account that has been copied to a local computer and remains synchronized with the server account so that both locations contain a matching set of data."(Mac OS X Server User Management, p. 46).
And it has been around since 10.3, so it is not something new to Leopard.

My iPhone was stolen and I have contacted the police who are using the meid number to locate. How does this work and what are my chances of getting the phone back?

My iPhone was stolen. I used Find My iPhone app to lock it and display a message. The phone has not connected to the internet to locate it. I contacted the police and they have taken my meid number. How does this work and what are my chances of getting the phone back? Are there other ways the theif can use it. I was told once they put in a new sim card and use it, whatever software the police have, it will show up.

Honestly? In the US (I can't speak to other countries, though I doubt it works much differently in a lot of the world) The police took your report and filed it either in their computers or, on paper. They will now not think of this again. The only time it will cross anyones mind is if, in the course of entering information into evidence about items recovered or seized at a crime scene, the serial number of an iPhone that was found/seized happens to match yours, in which case you will be contacted.
The police in the US can and will do nothing to 'blok' the phone and it's not worth their time to try and locate it unless you know for a fact that it was stolen by a big time drug lord, master criminal, or some other such prime target and they can get a court order to track the location of the phone in order to locate this individual for your own purposes. If they do that, they'll probably keep him under surveilance for a year or so before they act.
Basically, the police don't care about your phone. If they find it, they will give it back to you. They are not, however, going to go looking for it. They have better things to do.
I'm sorry, but that's the way it is.

What is UMA exactly? How does it work?

What is UMA exactly? How does it work?
I have T Mobile but am not subscribed to Hotspots at Home. I do pay for the BB unlimited internet package.
When I am connected to my router at home, it goes to UMA. But other times, it just says wifi and is still connected to my router -- but NO UMA. I haven't made any changes.
What is this?

Here is a KB that discusses UMA:

What is "Assisted GPS" on the iPad and how does it work?

What is "Assisted GPS" on the iPad and how does it work?

I purchased the iPad mini Wi-Fi & Cell because it has GPS. OK, it is assisted GPS but the GPS works very well as stand alone. I got the iPad mini for use in flight, so I dont even have a sim card in it. The GPS works perfectly in flight under all conditions. I have cross checked it against typical approved aircraft installations and it is very accurate at all times. I use it in Wi-Fi mode on the ground when updating my aviation database, when planning a flight, or similar circumstances. The primary advantage of A-GPS is quick location reading when first turned on, when on the ground where the GPS satellites signal may be of reduced quality. At 10,000 feet plus, it is a stand alone GPS. I have frequently turned the iPad off in flight for periods of time and when powering up, it gave me accurate positioning in a few seconds, never exceeded 10 seconds. I have also tested my iPad on the ground, using the aviation maps, and the GPS works perfectly also.
It remains possible that there is some feature that enhances the GPS when on the ground, even if there is no sim card in the iPad. But I doubt that any of these would work in an aircraft at high altutide. Nonetheless, I would appreciate knowing more about this.
