What is the purpose setting apple ID in Users and Groups?

What is the purpose of setting the apple ID in Users and Groups preference pane of System Preferences? Is it really necessary? All of apples services can still be used without setting an apple ID (like iCloud, iMessages, FaceTime, iTunes, etc...). I am sure apple has a reason for it just would like to know what it is. Anyone have an idea? Thanks for the help.

ya, I knew about that but I think it also has something else to do with screen sharing, file sharing and back-to-my-mac. Thank you for the help.

What is the diference between apple tv and airport express?

What is the diference between apple tv and new apple tv2?

Airport is a router, Apple TV is a set-top box.
http://www.apple.com/airportexpress/
http://www.apple.com/appletv/
Original Apple TV had a hard-drive, and has been discontinued for quite some time.
ATV2 is a streaming only device, smaller, and use less power. It is also now discontinued
The current model, ATV 3, has a better chip allowing for 1080P playback.

Whats the range of apple airport express

whats the range of apple airport express.

The effective range is about 150 feet or approximately 50 meters when there are no obstructions in the signal path between the AirPort Express and the wireless device receiving the signal.
But, walls, ceilings and other obstructions absorb a great deal of the signal in a home, so it is not possible to predict how the AirPort Express might perform in your home until you try it out in your home.
In general, you would not want the signal to have to negotiate moving through more than a few walls. A ceiling, because it is much thicker than a wall, will absorb a good deal more of the signal.

IPod Touch Newbie: What is the purpose of the iTunes app on my iPod Touch?

What is the purpose of the iTunes app on my iPod Touch?
All it does is connect to the iTunes store if I'm near a WiFi connection. It appears to be useful only for impulse purchasing of media. So why is it not named "iTunes Store"? It appears to have no other function.
Also, to listen to my iTunes music on iPod Touch I have to click on the Music button...not the iTunes app. What logic is that?
Also, iTunes has synced a movie for me, but I have no clue how to view it on the iPod Touch. It doesn't appear in iTunes on the iPod Touch, and there is no "Movie" button anywhere. What am I missing? I can't find it anywhere.

For purchasing music, downloading podcasts,etc.

What is the purpose of the 1394 and USB jacks on the 30" Cinema?

I have a 30" Cinema display connect to my (current-model) Mini via the Thunderbolt port and an Apple Dual-DVI adapter.
The back of the display has a pair of USB jacks and a pair of Firewire jacks, and the adapter has cable connections to match. What is the purpose of all these connections? I can tell you right now, it seems that nothing is coming or going through any of these paths. The Cinema display is working just fine but these miscellaneous connections aren't live as far as I can tell.
What would be great is if the FW tail on the adapter could be used as a second FW port for the Mini. Can that be made to work? Is there some way to route a FW signal to the Displayport?
TIA for any thoughts on this matter.

If I have to connect one Cinema FW port to the sole FW port on the Mac Mini, that doesn't gain me any additional ports--it consumes one of two ports and leaves me a net of one open port--the same quantity I started with.
The display's FireWire cable (not one of the ports on the back of the display) connects to the computer's FireWire port (via a FW400 to FW800 adapter). This uses up one computer FireWire port, but the display has two FireWire ports, so you gain one port.
It's the same for USB. You lose one port of the computer but get two on the display.
BTW, your response implied that the Thunderbolt port "contains" both USB and FW connectivity. Can I simply tap off the FW and feed my external FW hard drive directly from the Thunderbolt port?
Thunderbolt doesn't include USB and FireWire directly. Instead it includes a version of PCI. Apple is making some simple Thunderbolt to FireWire or Internet adapters, but they have only one Thunderbolt connection, so if you used one, there would be no place to connect your 30" display. (The HDMI port is limited to 1920 x 1200, so cannot drive a 30" display at full resolution.)
Belkin is coming out with an adapter that you could use, but it is not cheap.

While defining a columnar table, what is the purpose of column store type

Hi folks
I have two questions related to columnar table definition.
1. What is the purpose of column store type.
While defining a columnar table, what is the purpose of column store type (STRING ,CS_FIXEDSTRING,CS_INT etc) , when I define a table using the UI I see that the column is showing STRING but when I goto EXPORT SQL it does not show. Is this mandatory or optional ?
2.VARCHAR Vs. CHAR - In the UI when I create the table I do not see the CHAR option , but I do see lot of discussion where people are using CHAR for defining the columnar table. Not sure why UI dropdown does not show it. I also read that we should avoid using VARCHAR as those columns are not compressed, is that true, I thought the column store gives compression for all the columns. Are there certain columns which cannot be compressed .
Please let me know where I can find more information about these two questions.
Poonam

Hi Poonam
the CS_-data types are the data types that are used internally in the column store. They can be supplied but it is not at all required or recommended to do so.
SAP HANA will automatically use the correct CS_-data type for every SQL data type in your table definitions.
To be very clear about this: don't use the CS_-data types directly. Just stick to the SQL data types.
Concerning VARCHAR vs CHAR: fixed character data types are not supported anymore and don't show up anymore in the documentation.
I have no idea why you believe that VARCHAR columns are not compressed but this is just a myth.
create column table charcompr (fchar char(20), vchar varchar(20));
insert into charcompr (
    select lpad ('x', to_int (rand()*20), 'y'), null from objects cross join objects);
-- same data into both columns
update charcompr set vchar = fchar;
-- perform the delta merge and force a compression optimization
merge delta of charcompr;
update charcompr with parameters ('OPTIMIZE_COMPRESSION' ='FORCE');
-- check the memory requirements
select COLUMN_NAME, MEMORY_SIZE_IN_TOTAL, UNCOMPRESSED_SIZE, COUNT, DISTINCT_COUNT, COMPRESSION_TYPE
from m_cs_columns where table_name ='CHARCOMPR'
COLUMN_NAME    MEMORY_SIZE_IN_TOTAL    UNCOMPRESSED_SIZE   COUNT   DISTINCT_COUNT COMPRESSION_TYPE
FCHAR       3661                    70285738            6692569 20              RLE
VCHAR       3661                    70285738            6692569 20              RLE
We see: compression and memory requirements are the same for both fixed and variable character sizes.

What is the purpose of Destination Function on Submit Button?(Doesn't work)

Hi Gurus,
There is a property "Destination Function" on Submit buttons.
What is the purpose of this field.
I tried setting some values here expecting following behavior in order:

2. User will be navigated to the OAF page related to the Destination Function.
Destination Function property probably point to setInvokeFunction method of the OASubmitButtonBean.
Please advise on this.

What is the purpose of open/close connection data socket?

Hello everyone,
I am writing and reading values in OPC Server through data socket. What is the purpose of open/close connection data socket when writing /reading a value? Without the open/close connection element, it still work correctly. I am writing values in the server thru event stucture.I do not need any buffered reading or writing. What will happen if I didnt not use the open/close connection? Maybe it may cause some problems in my program which i didnt realise?
And I have attached an example of my program. Thanks

Hi YehChia,
I was talking about something like that:
1. Not good. since with every iteration the DS connection needs to be opened and closed.
2. Good. Since you open the connection only once then do the reads and close it afterwords.

OIM: What is the purpose of "Update" while editing group memberships

Hi,
This is when you lookup a user's Resource Profile and go to "Edit" link. The process form shows up along with a drop down to edit the group memberships. When we select one of the choices such as "Groups" another window pops up where we could add more entires into the child form. In this form there is an "Update" column with a radio button besides a "Remove" column. What is the purpose of this "Update" column? We can add or delete child entries but what does update do? Is there a way to remove this selection altogether?
Thanks in advance

Update I can see used for a cases where you have multiple columns on a child table entry and want to change one of them. Strictly speaking, you can update a single column child table rather than delete and insert also. Access policies always do insert and delete actions, but you will want to implement an update task as well if you expect anyone to be editing child tables on resources directly.

What is the purpose of Multiproviders???

Hi Everyone,
I am currently trying to create a multiprovider.
I have read the SAP documentation but I still do not understand in what circumstances should I create a multiprovider for reporting.
Would appreciate if anyone can provide details on what is the purpose of multiproviders?
Assuming I have the following scenario, should I create a multiprovider for reporting?
Infocube A:-
Characteristic
- Employee Number
- Cal Month/Year
- Shift Type
Key Figure
- Hours
Infocube B:-
Characteristic
- Employee Number
- Cal Month/Year
Key Figure
- Amount
I need to report on both the key figures for each employee and what is the shift type of the employee for the specific cal month/year. The employee number, cal month/year and shift type will be used as selection parameters.
I am thinking of creating a multiprovider for this reporting need but I think there will be some problems.
For example:
1) If I input the employee number and shift type as selection parameters, the amount column will be empty when the report is displayed.
2) If I input on the employee nunmber, then I'll be able to see both the key figures when the report is displayed but the data are on different lines which does not make sense to users.
Emp ID   Shift Type    Cal Mth/Yr   Hours     Amount
200001   Shift         05.2006       10
200001   Not assigned 05.2006                 1000
Only if I don't show the shift type column, then the record will be display in a single line.
How can I rectify such a problem.
Please advise.
Thanks.
Shunhui.

Hi,
A MultiProvider is a type of InfoProvider that combines data from a number of InfoProviders and makes it available for reporting purposes. The MultiProvider does not itself contain any data. Its data comes entirely from the InfoProviders on which it is based. These InfoProviders are connected to one another by a union operation.
InfoProviders and MultiProviders are the objects or views that are relevant for reporting.
Multiprovider - used when we want to report on chracteristics and keyfigures that are in different data targets.

What is the purpose of Defining a requirement in the procedure?

Hi
I have a query related to the Output type .
What is the purpose of Defining a requirement in the procedure?
And where shall we code for a new requirement and also what shall we code in it?
Thanks

Requirement Use
If the requirement is fulfilled (SY-SUBRC = 0), then output determination also takes into consideration output type or the access sequence, for which the requirement has been specified.
Output determination:
An object that checks whether the application data (for example, data determined in Customizing) corresponds to the condition records.
If this is the case, one or several messages are "found," which can then be processed (for example, sent electronically).
The condition records are searched for according to a predefined hierarchy in message determination.
After defining a new requirement no say 604 for billing pricing procedure and activating it, the standard sap system creates a routine with the no: 604 specifically for billing. So the name of the program automatically created by SAP will have the naming convention something like RV64A604. then you need an access key to go to the change mode for writing any logic. Then just put a break-point and then execute VF01 or VF04, then the cursor position directly goes into this routine, where the pricing structures KOMK and KOMP have the visibility. So based on the values flowing inside this structures, you can probably code that suites the business requirements.
there are some useful transactions like VOFM for maintaining the requirements and formulaes for a pricing procedure.
For viewing the requirements in the procedure you can also go to V/08 transaction.

What is the purpose of the chain (lock symbol) between a solid color layer and its vector mask?

What is the purpose of the chain (lock symbol) between a solid color layer and its vector mask in the layer panel when creating shape layers with a shape tool? I'm just curious when locking or unlocking the solid color layer and its vector mask can make a difference.

I don't understand what you said and your shape layer looks different then mine using CS5.
When the chain is deselected, I can't do anything with the move tool on the shape layer. This is the only difference I can find. Making the solid color uniform or not doesn't change anything.
Your example shows that you moved the position of the solid color, how did you do that? I can create a solid color layer and change its uniform look by applying an effect like gradient but I can't move the solid color itself around. How is this possible?

What are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

what are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

Thanks - Even though I'm years out of warranty I got chat help from Apple (I said they should help me since the codes aren't published.) We covered three different questions, and although I didn't get a specific decoding of the error code, I got confirmation of what other comments here imply - it might have helped that I indicated I'd already been here - and useful links to how to do back ups, including to CD(s). (I don't have a lot of data on this computer yet)
Now I need to figure out how to decide how hot-to-the-touch is "too hot" for the metal frame at the top of the iMac to decide whether I'm getting adequate fan performance or insufficient. While chatting I initially reported it was cool at the bottom and warm at the top. Apple hadn't asked, but their response prompted me to feel it again, and I'd say the top was hot, not warm - I updated but Apple didn't comment further except to conclude after addressing the other questions that I should take it in for further assessment - don't really want to bother with that.
