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's the difference between "local reminder" and "push notification?

A friend has been bugging me about this, does anyone know what's the difference between "local reminder" and "push notification" in an iPhone app?

In a nutshell, local notifications are popup notifications from applications on your phone, based on data that's already on the local phone. Push notifications are popup notifications you get when new info (like an email, tweet, or update from something like Facebook) gets pushed to your device from a server.

What is the difference between Instance variable and Global variable?

Hi folks,
Could you please explain me, "what is the difference between Instance variable and Global variable?"
Are they really same or not?
--Subbu

Hi flounder,
I too know that there is no such a term GLOBAL in java.
generally people use to say a variable which is accessible throught out the class or file has global access
and that will be called as a global variable...
my point is very much similar to what Looce said.
In simple that is not a technical term, but just a causual term.
In technically my question is, "What is the difference between a instance variable and public variable?".
Hi looce,
Thanks for the reply. even thats what my understanding too....in order to confirm that i raised this question..
Your reply has given a clear answer...... thanks again.

What is difference between bex analyser and bex browser

what is difference between bex analyser and bex browser . please explain what are use of both and what we do in both.

hi
Bex Browser
The Business Explorer Browser (BEx Browser) makes it possible for you to access all document types of the Business Information Warehouse that are assigned to your role or that you have stored in your favorites. You can select and open documents assigned to you in the BEx Browser or store and manage new documents in the BEx Browser.
Document types that you can work with in the BEx Browser are:
· BW workbooks
· Documents that are stored in the Business Document Service (BDS)
· Links (references to file system, shortcuts)
· Links to internet sites (URLs)
· SAP transaction calls.
· Web applications and Web templates
· Crystal Reports
Bex Analyser
The Business Explorer Analyzer (BEx Analyzer) is the analysis and reporting tool of the Business Explorer that is embedded in Microsoft Excel.
Features
You can call up the BEx Query Designer in the BEx Analyzer, in order to define queries. Subsequently, you can analyze the selected InfoProvider data by navigation to the query created in the Query Designer and create different query views of the data. You can add the different query views for a query or for different queries to a work book and save them there. You can save the workbook in your favorites or in your role on the BW Server. You can also save the workbook locally on your computer.
Beyond that, you can precalculate the workbook and distribute it by e-mail to recipeients or you can export it to the Enterprise Portal and make it accessible to other employees in the company.
You can start queries in a standard view (with a Standard Web Template set up in Customizing) in the Web browser and forward the URL or continue to navigate on the Web. Similarly, you can export the Web query to MS Excel 2000.
Overview of the Functional Area of the BEx Analyzer:
·        BEx toolbar
You access the functions of the BEx Analyzer from the BEx toolbar, which takes you to the BEx Open dialog box where you can open existing queries, or to the BEx Query Designer where you can create new queries or change existing queries.
·        Evaluating Query Data
The BEx Analyzer offers convenient functions for evaluating and presenting InfoProvider data interactively. In the BEx Analyzer, you can add queries to workbooks, navigate within them and refresh the data. You can also process the queries further in Microsoft Excel or display them in the Web browser in a default view.
Navigation of a query allows you, for example, to filter characteristics on a single value, drilldown on all values for a characteristic, regroup characteristics and key figures in the rows and columns of the results area, or hide key figures. Navigation results in different views of the InfoProvider data. In addition, a range of further functions is available which allow you to edit a query interactively (for example, sorting, cumulated output, among others). In addition, you can use the editing functions in Microsoft Excel in order to set up individual format templates, to print results areas, or to create graphics.
·        Queries in Workbooks
Queries are inserted into workbooks so you can display them. When you insert a query, a link is made between the cell areas of the worksheet and the data of the InfoProvider upon which the query is based. A link therefore exists between the Business Explorer and the Business Information Warehouse Server (BW Server).
When inserting a query into the workbook, a VBA routine is automatically generated in the workbook. You can also connect the Business Explorer with your own VBA programs (Visual Basic for Applications).
You can create workbook templates, into which you can insert your queries. Workbook templates can contain pre-determined items for the area of the query, formatting settings, logos, VBA macros, and so on.
·        Precalculating workbooks
You can precalculate and distribute workbooks with the BEx Broadcaster, which is a Web application you get to form the BEx toolbar. The system generates MS Excel workbooks with historical data. You determine the time for precalculation yourself: You can have workbooks precalculated at a predefined time or they can be precalculated whenever data in the underlying InfoProvider changes. You can have the precalculated workbooks sent by e-mail or you can export them into the Enterprise Portal, where you can make them available to employees within your company.
Activities
To start the BEx Analyzer, choose Start ® Programs ® SAP Front-end Business Information Warehouse ® SAP Business Explorer Analyzer.
You can also access the BEx Analyzer via SAP Easy Access ® SAP Business Information Warehouse ® SAP Menu ® Business Explorer ® Analyzer or in the Business Explorer Browser using the Business Explorer Analyzer symbol in the menu bar.
Hope this will solve your issu

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

Re: what is difference between sap locking and database locking

Hi Paluri
Here is the difference between SAP locks and Database locks, i will try to find the solution to your code.
Regards
Ashish
Database Locks: The database system automatically sets database locks when it receives change statements (INSERT, UPDATE, MODIFY, DELETE) from a program. Database locks are physical locks on the database entries affected by these statements. You can only set a lock for an existing database entry, since the lock mechanism uses a lock flag in the entry. These flags are automatically deleted in each database commit. This means that database locks can never be set for longer than a single database LUW; in other words, a single dialog step in an R/3 application program.
Physical locks in the database system are therefore insufficient for the requirements of an R/3 transaction. Locks in the R/3 System must remain set for the duration of a whole SAP LUW, that is, over several dialog steps. They must also be capable of being handled by different work processes and even different application servers. Consequently, each lock must apply on all servers in that R/3 System.
SAP Locks:
To complement the SAP LUW concept, in which bundled database changes are made in a single database LUW, the R/3 System also contains a lock mechanism, fully independent of database locks, that allows you to set a lock that spans several dialog steps. These locks are known as SAP locks.
The SAP lock concept is based on lock objects. Lock objects allow you to set an SAP lock for an entire application object. An application object consists of one or more entries in a database table, or entries from more than one database table that are linked using foreign key relationships.
Before you can set an SAP lock in an ABAP program, you must first create a lock object in the ABAP Dictionary.

What is difference between User Exits and BAPI

hello sap gurus
what is difference between User Exits and BAPIs

http://www.sap-img.com/abap/what-is-user-exits.htm
www.****************
Where as this customer exits are again divided into:
1. Menu Exits.
2. Field Exits.
3. Screen Exits.
4. Function module exits.
These all the things comes under Enhancements.
User exits
1.A user exit is a three character code that instructs the system to access a program during system processing.SXX: S is for standard exits that are delivered by SAP.
XX represents the 2-digit exit number.UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number
2.USER EXITS are FORMS and are called by SAP standard programs
using PERFORM.
3.Inside the form (user exit) you can read and change almost
any global data from host program.
4. User exits are more flexible because you have more information to use in your code but on the other hand , it is very easy to manipulate erroneously global data and lead the standard program to a dump or even to make database inconsistent.
5.While changing User-exit,Access Key is required,
BAPI is nothing function module but which is remote enabled, means you can access this fm through other SAP or non-SAP system by assingning to business object,which we can crea in SWO1 transaction.

What is difference between bus.Area and plant

dear experts,
what is difference between bus.Area and plant?
thanks
Rajakarthik.

Hi
Plant and Business Area are not the same.
Business Areas are configured in FI module as per the Product lines or geographical operations basis.
Where as The plants created in the logistics (General) module are assigned to the company code. That means all transactions taking place in the plants are posted to the attached company code in SAP FI.
You can post a business area to several company codes and use it for cross-company-code reporting.
The R/3 System uses a combination of plant and division to assign the relevant business area. When you use the R/3 System to automatically draw up accounts for business areas, you can assign only one business area to a combination of plant and division. Plants and divisions can be assigned and combined in several different ways.

What is difference between SAP R3 And SAP IS Mills Product

HI Friends
What is difference between SAP R3 And SAP IS Mills Product
What are the futures are availables in IS MIlls
Regards

Hi,
SAP R/3 is the central enterprise version. It is not specifically designed for any inducstry sectors and it can cater many of the industry types.
Is is developed for specific industries an for SMB's (small and medium business). It will have components specifically for the industry.
The SAP Mill Products component adds sector-specific functionality to an ERP system to satisfy the complex requirements of mill industries (e.g. metal, wood, paper, textiles, construction materials, and cable sectors).
These industry segments differ from others primarily in that the materials used have a large number of characteristics and variants. The materials in the segments listed above are also predominantly area-based (e.g. paper, textiles, plastic film) or length-based (e.g. cables, piping). Account must be taken of these material characteristics throughout the entire supply chain.
To cater for the particularities of these industry segments, SAP Mill Products features processes and functions that cover the entire supply-chain cycle from product design and configuration, through planning, order processing, capacity planning and production, to final delivery. Additional functions are available in costing and inventory management. SAP Mill Products are also integrated into Quality Management, Financial Accounting, and Controlling.

What is difference between u2018credit exposureu2019 and u2018credit limitu2019?

Hi
What is difference between u2018credit exposureu2019 and u2018credit limitu2019?
What transaction I can used for to see these tow information?
best regard
francoise

Credit exposure is total AR and open sales values. Credit limit is used for block sales documents if the total exposure will exceed the credit limit. For Example:
Credit Limit : 600
   Open AR ( Customer Balance) : 100
   Customer Open Orders (Order Quantity have been confirmed, but no delivery document is created) : 100
   Open Delivery (Delivery has been created, but no billing ) : 100
   Open Billing (Billing is created, but has not release to Financial Accounting): 100
So far, the credit exposure is 400. If a new sales order is coming with value of 260, the sales order will be blocked, but the credit exposure is still 400.
Then if someone release the new sales order , then the credit exposure is 660.
Hope this is useful for you.
