What are state objects, and what are they used for ?
tried to find some information in the documentation and internet. but i couldn't find a good explanation with an example what that is and what it is used for.
thanks for any good answer !
Wrapper classes are used to enclose primitive data
types so that they can be used in instances where an
object is required. For example, if you want to add an
integer to an ArrayList, you can't use this:java.util.List al = new ArrayList();
int i=123;
al.add(i);because the ArrayList expects data of type object. In
order to all the integer to the ArrayList, you must wrap
it in the Integer wrapper class. This works:java.util.List al = new ArrayList();
int i=123;
al.add(new Integer(i));Hope that helps.

What is authorization object and how to create it for a table
Hi All,
What is authorization object and how to create it for a table?
ThanksHi
Authorization
For authorization checks, there are many ways of linking authorization objects with user actions in an SAP system. The following discusses three possibilities in the context of ABAP programming.
Authorization Check for Transactions
You can directly link authorization objects with transaction codes. You can enter values for the fields of an authorization object in the transaction maintenance. Before the transaction is executed, the system compares these values with the values in the user master record and only starts the transaction if the appropriate authorization exists.
Authorization Check for ABAP Programs
For ABAP programs, the two objects S_DEVELOP (program development and program execution) and S_PROGRAM (program maintenance) exist. They contains a field P_GROUP that is connected with the program attribute authorization group. Thus, you can assign users program-specific authorizations for individual ABAP programs.
Authorization Check in ABAP Programs
A more sophisticated, user-programmed authorization check is possible using the Authority-Check statement. It allows you to check the entries in the user master record for specific authorization objects against any other values. Therefore, if a transaction or program is not sufficiently protected or not every user that is authorized to use the program can also execute all the actions, this statement must be used.
AUTHORITY-CHECK OBJECT object
ID name1 FIELD f1
ID name2 FIELD f2
ID namen FIELD fn.
object is the name of an authorization object. With name1, name2 ... , and so on, you must list all fields of the authorization object object. With f1, f2 ... , and so on, you must specify the values that the system is to check against the entries in the relevant authorization of the user master record. The AUTHORITY-CHECK statement searches for the specified object in the user profile and checks the useru2019s authorizations for all values of f1, f2 ... . You can avoid checking a field name1, name2 ... by replacing FIELD f1 FIELD f2 with DUMMY.
After the FIELD addition, you can only specify an elementary field, not a selection table. However, there are function modules available that execute the AUTHORITY-CHECK statement for all values of selection tables. The AUTHORITY-CHECK statement is supported by a statement pattern.
Only if the user has all authorizations, is the return value sy-subrc of the AUTHORITY-CHECK statement set to 0. The most important return values are:
· 0: The user has an authorization for all specified values.
· 4: The user does not have the authorization.
· 8: The number of specified fields is incorrect.
· 12: The specified authorization object does not exist.
A list of all possible return values is available in the ABAP keyword documentation. The content of sy-subrc has to be closely examined to ascertain the result of the authorization check and react accordingly.
REPORT demo_authorithy_check.
PARAMETERS pa_carr LIKE sflight-carrid.
DATA wa_flights LIKE demo_focc.
AT SELECTION-SCREEN.
AUTHORITY-CHECK OBJECT 'S_CARRID'
ID 'CARRID' FIELD pa_carr
ID 'ACTVT' FIELD '03'.
IF sy-subrc = 4.
MESSAGE e045(sabapdocu) WITH pa_carr.
ELSEIF sy-subrc <> 0.
MESSAGE e184(sabapdocu) WITH text-010.
ENDIF.
START-OF-SELECTION.
SELECT carrid connid fldate seatsmax seatsocc
FROM sflight
INTO CORRESPONDING FIELDS OF wa_flights
WHERE carrid = pa_carr.
WRITE: / wa_flights-carrid,
wa_flights-connid,
wa_flights-fldate,
wa_flights-seatsmax,
wa_flights-seatsocc.
ENDSELECT.

Could you explain it in the details.

That doesn't really help.
Where does AlwaysFilter come from? Is it part of the core API, or a 3rd party library? If the latter, which one? And in what do the API docs for this class not answer your question? -
What are the algorithem and container to be used for this problem?
Say I have a class with the following properties:
groupMonth //String (jan,feb,mar�)
accumulatedLasyYear //double
accumulatedThisYear //double
What will be the best container/algorithm to use for objects from the class above so I can have them sorted by month (I know it�s a string) AND GROUP the months together (and the accumulated as well)
Example:
Jan 4 8
Feb 2 3
Mar 5 2
Jan 3 5
Feb 4 2
Mar 9 3
The output should be:
Jan 7 13 //(4+3, 8+5)
Feb 6 5
Mar 14 5
Thanks for any thought�I'd suggest a java.util.Map<String, Set<WhateverClassYouveDefined>>. The keys are the year, the values are Sets containing all objects of that year. Iterate through your list of objects and group them into the right set using the map.
Then I'd suggest looping through the keys to get each month's worth. Since you know what all the keys will be in advance, and there's only twelve of them, create an array of the twelve month strings. Loop through that array, and for each value grab the corresponding Set from the map.
Then for each set you get, iterate through its contents, get the values, and add them.
Then just print the month and the sums of values from the set, and go on to the next month. -
What is context objects and how we can use it Receiver Determination
hi,
i have situation here a idoc is triggered into the xi and i need to use the conditions in the receiverdetermination in that condition i need to use context object how i can use it? and what is the difference it makes and why i need to use it?
thanks in advance
AmareshHI,
Context objects are alternative to XPATH expressions. It is like macros in other programming langugage. If you define this , you can use this object in the receiver determination while doing conditional receiver determination

If I want to make a small change to a legacy project of years ago, I want to limit my risk by using the exact same versions of LabVIEW, NI-RIO etc. So I check out the project from the repo, but I don't know how to check what versions were used when the last know good build was made. I don't want to introduce issues by mass-recompiling to the latest version.
What is best practice in this case? I could, before every repo commit, take a screenshot of MAX's software tree and save this in the project folder.
Any ideas?
Solved!
Go to Solution.The report is a great idea! I store both a max technical report and a project.NCE (HW config export) with each of my projects for this exact reason. Those files have sure come in handy!
Also- its a good idea to make an image of the target as accepted and archive it somewhere. ESPECIALLY for PXI based systems from NI. (When the customer comes back for a "duplicate" just send the image with the PO and the system arrives fully configured)

What are replications objects and subscriptions???
Hello All,
I am working with CRM 5.0
I want to know what are replications objects and subscriptions and how it is work with sites and BDocs? The process is not clear to me and how is the relationship between them?
Regards
Jacopo FrancoisHello Jacopo,
The CRM Middleware course material CR500/CR540/CR550 details out the concepts of a Replication Obj,Publication and Subscription.
Let me try and illustrate this concept with a real-world example. This is normally the example I provide whenever I train employees.
What do you do when you want to subscribe for SAP Netweaver magazine published from SAP Press?
1) SAP Press publises a number of SAP magazines. So, first you select the publication of your choice. Your publication = "SAP Netweaver".
2) Next, you have to subscribe for it in the website by furnishing your credit card details, shipping address and the duration of your subscription. So, that becomes your subscription. So, a publication can have many subscriptions (sent by many people)
The replication object is just the abstraction which collects all the publications and their corresponding subcriptions and relates them a particular Bdoc type. Normally, the name of a replication object = Name of the Bdoc type. E.g. BUPA_MAIN. Replication objects can be bulk objects or simple intelligent objects depending on whether mass data or filtered data is desired. Naturally, there will not be any subscriptions for a bulk replication object.
Now, once you have created a site and have done its configuration, you can associate the site to a number of replication objects depending on what type of data would the site be interested in.
Hope you are now able to figure out the meaning of these MW terms and understand the relationship between them.
Please reward with points if this helps!
Thanks,
Sudipta. -

What are Crypto Cards, and what are they different from Java Cards?
Hi,
I just heard the name 'Crypto Card'. I thought Java Card is the only standard for smart card. Could anyone tell me what are Crypto Cards, and what are they different from Java Cards? Thanks in advance.
JoeyProbably any card that offers cryptographic capabilities (crypto coprocessor) could be called "Crypo Card", but likely the term was referred to cards offering a pkcs#11 interface.
Pkcs#11 is the standard for accessing crypto devices, like tokens, cards, or accelerators. Such a device can be easily accessed for example from your browser to perform cryptographic and digital signature operations.
A Javacard can operate as a pkcs#11 device in you install on it an applet dealing with the pkcs#11 requests. -
I have an iMac with OS X Lion 10.7.5,an iPhone 5s with iOS 7.1.2 and an iPad with iOS 7.1.2. all software is up to date. My problem is I do not receive all my e-mail on all 3 devices all the time. I seem to get them on my phone , but not all show up on my iMac or iPad. Any ideas as to what is going on and what can I do to resolve this issue? thanks
On the iPhone, go into Settings -> Store and turn off "Automatic Downloads" for Apps (and Music and Books, if you wish). You can also do that on the iPad to prevent it from going in the opposite direction.
That will stop any automatic downloading... to prevent them from coming over when using iTunes, select the phone (under Devices), Apps, and then uncheck "Automatically sync new apps." Again, do the same for the iPad if you wish. -
Some BAPIs are auto commit and some are not. what is the reason?
Hi all,
currently i am working on BAPI.I found that some BAPIs are auto commit and some are not. can anybody tell me what is the reason.hi,
one option to find the difference is you have to look for parameters like test run or commit .
If the function module doesn't have them, then it means you have to use BAPI_TRANSACTION_COMMIT or BAPI_TRANSACTION_ROLLBACK based on the success or failure. -
What ideal Win Server and Hardware are recommended for 11g DBs
What best Win Server and Hardware are recommended for 11g DBs?
- Processor
- Memory
- Storage
- Network
- Etc...
Following is the scenario:
- The server will be for development and test DBs
- More than one databases will be installed each for each project
- Maximum 4 databases will be accessed each time
- Maximum DB size for each DB will be in couple of GBs.Which version of 11g ? For 11gR2, see the requirements here - http://download.oracle.com/docs/cd/E11882_01/install.112/e16773/reqs.htm#i1011417
Any server that exceeds these requirement will suffice. Obviously the more the number of processors, the faster the processors, the more the RAM, the more the disk etc etc, the better.

I just download mountain lion to my mac, now microsoft office suite doesn't work....it says 'you can't open the application 'microsoft word' because PowerPC applications are no longer supported. What does this mean and what do I have to do to fix it?? HELP!!
Install Snow Leopard on another boot partition, or upgrade Microsoft Office to a newer version, or use any number of better alternatives. Some of them are free.
Consider
LibreOffice (donation-supported)
NeoOffice ($10)
OpenOffice (completely free)
In addition to the above I also recommend Apple's Pages ($19.99). I use OpenOffice and Pages and have been completely Microsoft - free for over a year now. Life is better without Microsoft.
