What are global dependcies & local dependcies in VC

Hello
When do we call global object dependency and when do we call local object dependency
I am presuming that
we call local object dependency when we maintain object dependencies (selection conditions, preconditions, procedures) in BOMs & Routings
we call global object dependencies when we maintain object dependencies in Configuration profile
As in configuration profile it is maintained centrally & not subjected to a specific object while in BOMs & Routings we select a characteristic value and maintain the object dependencies
Please clarify

Global dependencies :
#They are independent of any object.
#They are identified by a name that you assign, and are maintained and managed centrally.
#If you change a global dependency, the change affects all the objects where the dependency is used.
Local dependencies :
#They are only available to the object for which you create them
#You cannot use the central maintenance functions on these dependencies
#you cannot allocate them to other objects
#They are identified by a number assigned by the system, not an external name

What are global templates in SAP SD?

I was trying to know abt global templates and how they are used in SD

Hi
A Support Package contains a collection of error corrections. You can only import complete Support Packages and in a specified sequence. Each correction in a Support Package is documented in an SAP Note
SAP Notes give you instructions on how to remove known errors from SAP Systems. They include a description of the symptoms, the cause of the error, and the SAP Release and Support Package level in which the error occurs.
Depending on the type of error, an SAP Note may also include:
· Workarounds
· Descriptions of how to correct repository objects in the ABAP workbench, known as correction instructions
· Links to Support Packages that solve the problem
You can access SAP Notes both from the SAP Service Marketplace and SAPNet - R/3 Frontend

What are the best practices to use GLOBAL Variables

Hi,
Please guide how Global Variables can be declared and how they can be initialized.
Further please guide what are the impacts of Global Variables(if any) on the memory of CLIENT or SERVER, if they are not initialized or freed up after usage.
Thanks.
Regards.

My preference is not to use them and to use parameters or package variables. There is not real control on globals so you can end up with an applicatios that has lots of them that are only used once but persist for the user session.I second that. I don't know how often I searched for bugs caused by typos in the names of global variables. Plus the fact that they are only of datatype VARCHAR2. If you are using share_library_data you could also use Package globals in a forms library to share data between called and calling forms. Or you could use a database package...

Yosemite 10.10.2 server app. FTP help. I have a program running in my local server enviroment that wants to FTP to my mac folder. It asks for the server , name, password, port and path. what are they?

So I have set up a localhost area in my Mac. I have the new server.app and I am running yosemite 10.10.2 .
I have a program running in my local server enviroment that wants to FTP to my mac .
It asks for the server , name, password, port and path. what are they?
I am pretty certain that the Serveris "localhost",
Name is my macs name (like my-mac-min)
password is "my login password"
and they suggest port 21.
But what is the file path, lets just say my site is set up http://localhost/siteftp and is actually at my Users/Sites/siteftp folder.
Why cant this program connect to the mac.
Is it because they are both operating in the same localhost enviroment,
could it be my folder permissions are not correct on siteftp folder?
Help please !

I tried turning the computer off and then back on. The alerts don't show the notice to update as resolved. Hopefully this is not a problem or an indicator or another problem. Should I ignore or reload 10.10.1 from the app store to trigger a resolved check in a green circle?
Interesting that I had to buy server software after my free Yosemite download. I would have hoped that the two pieces of software would have gone together without any complication. It is not positive to end up buying a problem. Ah well, time to move on.

To make things clear, here are two small examples that show how nasty locals and value properties can be to the naive programmer.
- Open the diagram of the race condition.vi before running it and try to predict what will be the values of the two counters after the third run.
- Use the Compare Locals Properties and Wires.vi to find out how slow locals and value properties can be (times 1000+).
This being demonstrated, I must add that I use globals and value properties quite often, because they are often very convenient

What are the types of routines

hi experts
can some one give me clear idea on what are the types of routine we use in sap bi
with scenarios?
what is CMC?
Please search the forum before posting a thread
Edited by: Pravender on Apr 7, 2011 12:56 PM

Hi,
In BI 7.0 we have the following types of routines.
1. Start Routine.
2. End Routine.
3. Expert Routine.
This routines can be used in the complex scenarios and to improve the performance of the loading time.
I am elaborating the routine in details here.
1. Start Routine : whenever you create a start routine, the system will automatically give you some predefined data declaration like structure of the type of your source. In start routine you can declare a local data declaration and Global data declaration also. I will give one example.
Suppose you are creating Start routine for transformation from Datasource to DSO. Then when you create start routine the System will provide you a structure of your datasource. By using this structure it will also define an internal table which will be used as changing parameter of a method of a class. It is this changing parameter where you have to do all sorts of manipulation. The changing parameter is both export as well as import parameter. This changing parameter will contain data in the package wise.
In start routine you can also read some database table and store that data into an internal table and this internal table data can then be read in the field level routine. In this case it acts as a substitute of master data look up in the field level transformation.
2. End routine : The end routine is also same as start routine, the only difference is that here the system will provide you with a structure of the target not the source. and rest is all same as start routine.
3. Expert routine : This is the strongest and most complex of all routines. This allows you to design the entire data flow of the transformation. If you create an Expert routine the system will automatically delete all the field level mapping, Start routine and end routine. You also have to take care of the error handling and monitoring

What are Adhoc reports

Hi all,
What are Adhoc reports in HR?
Best Regards
Akshay
Moderator Message: Interview questions are not allowed.
Edited by: kishan P on Nov 10, 2010 7:05 PM

Hi,
It may be difficult to provide a list of business scenarios across an enterprise where adhoc reports are used. However, In generic terms, adhoc reporting is used when your business users are not just information consumers, but are more of analysts having special reporting needs which are non-generic in nature, that BI teams can not provide pre-configured reports. (Typical scenarios where you have a global BW system and you want to let the local users create their local adhoc reports)
This, of course means, business users should have the requisite know-how to create reports and should be equipped with all relevant info( like authorizaions, rules for information dissemination etc.).
I always preferred creating queries at the most generic level and let the users create query views (instead of letting business users create adhoc reports).
Hope this helps.

Shall I use global or local variables for my program?

Hello,
1) I am using 2 while loops in parallele. One 50 ms timed and the other one 1000 ms. The 50 ms one gets data from a sensor. I want to display that data every 1000ms in the 1000 ms loop. I have used global variables to do that. Should I better use local variables?
2) This question deals with the VI I have attached
a) Shall I initialise the " Quitter programme " global variable in the main VI aswell ? Or is what I have done enough?
b)
I want the sequence to continue ( finishes the last sequence and goes back to the first one without any delay if possible ) until the user presses Quit. I am concerned about the " wait until " icon of the exterior main while loop ( set to be 250 ms at the moment ). This time, 250 ms, is the time it takes between the end of the last sequence and the beginning of the first sequence? Is that right? Once u start the first sequence, the while loop doesn’t do anything until the end of the last sequence ( my 3 sequences can take several minutes ) ?
Hope I am clear… lol
Don’t hesitate to ask any questions if not clear enough
thanks a lot,
David

Bonjour Marc. You will definitely have a race condition because you are writing to the global in a parallel loop. You could click the stop button in the quitter program, then before it is read in the main loop, the lower loop writes a false to it, and your click is lost. Why do you want a separate quitter program? You may have a good reason but it isn't clear here. I would not use globals or locals for this, just put your stop button on the main vi. You already have one, so why do you want another one in another vi? If you must do it this way, eliminate both lower loops. They are not necessary. The global default is set to false, so when you run the vi, it is false. The button mechanical action is set to latch when released, so after clicking it will turn true until the main vi reads it, then it will automatically turn false. So you don't need the lower loops to keep writing false to it. If you just eliminate both lower loops, it will work fine. The only purpose I could see for the quitter vi is to have one button cause several vi's to stop. Instead of doing it this way, put one stop button in your main vi, create a reference (right click - create - reference), and wire this reference into all subvi's that the main calls. The subvi's must be changed to accept the reference and use it. This would be a much better method to close all vi's with one button.
You could also get rid of the sequence structure (it hides code and makes it more difficult to read). Just put all your code side by side. The error in/out wire will ensure that the execution order will be fixed, just like in your first sequence with the open file and write file functions. Just wire the error out of the write vi to the second write vi, and then the error out of the second write vi to the close vi. No sequence structure needed, and all your code is viewable on one screen.
