Difference Between Conversions & Interfaces

Hi,
Any one knows difference between conversions and interfaces.
pls help me out with examples.
Advance Thanks,
Sudhir.

Nick,
I'm shocked and upset at your insuation here. Are you suggesting that both Venkata and Kishore didn't put lots of effort into writing those useful answers and by a freak occurrence they just happened to write the exact same thing word for word?!

Difference between Conversion progs and INTERFACES

Hi plz tell me ...
whats the difference between Conversion progs and Interfaces in ABAP .
wat are conversion progs ( exmple) and interfaces ( exmple ) ?
thnks in advance....

Hi
CONVERSION programs are the ones which have one time usage, usually when a legacy system is being replaced by a system like SAP, then the data has to be mapped from the legacy system to SAP system. Here the data to be converted is given on a flat file & is uploaded to SAP tables mostly using LSMW only. Conversions programs are BDC,BAPI and LSMW programs in which you upload all the related tables from the flat files.Those are one time programs.
Interface programs are those programs in which you fetch the data from the application server and process on theose data.These are helpful when you have to run any program in the backgroup when the presentation server is not working.
INTERFACE programs are the ones which are run at regular intervals, say weekly, monthly or even daily. Here the legacy system continues to co-exist along with SAP system, the legacy system might be useful for certain functionalities but the data might have to run thru SAP transactions for complex data maintenance at regular intervals.
In Simple
CONVERSIONS : Converting Legacy System DATA into a flat file
INTERFACES : Converting Flat File into SAP

what is the difference between conversion and interface?

Conversion: The legacy system may have a different representation for the data, from that of SAP. A conversion program basically aims at converting the data into a format that is acceptable for SAP.
Whereas an interface does the actual upload of the data into the SAP system through various means.

Difference between abstract interface and normal interface

Hello Friends,
What is the Difference between abstract interface and normal interface?....

What is the Difference between abstract interface and
normal interface?....The difference is that you didn't follow convention in the first case. All interfaces are implicitly abstract so you don't have to declare them as such.

Difference between Form Interface and Global definitions in Smartforms.

Hi guys!
I'm learning about Smartforms.
I would like to know which is the difference between Form Interface from the Global Settings and Global Definitions from Global settings as well, because in both of them I have to declare tables, structures, variables, etc. Could you please explain to me when should I use them?
Thanks!
Gaby

Two ways to use Smart Form:
1. by using Application Program
2. By coding in Smart form itself.
Now, if the 1st method is used then same interface can be used for multiple requirements. For eg two different programs Z1 and Z2, may use same interface. Hence a lot of efforts are reduced.
On the other side in 2nd method, multiple forms have to be created to fulfill different requirements.
Now, Global Definiton is something that is irrespective of which Program is being used, the form nodes can use the Global definition in all cases.
Also all tables etc must be declared in the Global setting.

Sana

Differences between conversion, migration and interface?

HI All,
can any one explain differences between data conversion, data migration and interface?
Thanks.

In my opinion, conversion and migration are just about the same thing - where you convert or migrate data from an older system/software to a new system/software. This is basically a one-time process. Interface is a regularly scheduled (hourly, daily, weekly, monthly etc) process that supports a regular business need (eg loading journal data into open interface tables for financial month-end close etc).

Difference between conversion program and Interface program

Hi All,
Can any body tell me what's the exact differenct between conversion program and Interface program?How will we will classify an object whether it is converion or Interface?
Thanks&Regards
Mahesh

hi,
conversion program is your migration- or mapping- program to convert data in the format of the SAP-Interface
example:
-(customer)conversion program for vendors ZFKMIGR01 creates a file in the format of interface RFBIKR00
with the foll. structures
BGR00
BLFA1
BLFB1
BLFBK
hope that helps

What is difference between using interface as source and table as source?

I am working on a batch flow which need several steps to populate data from source to target. For example, I need 5 interfaces to finish final data loading. I can either use interface or use temporary table as source and target for the interface 2, 3, and 4. It looks like both case will use tables no matter use interface or use temporary table. So my question is if there is any difference between these two (using interface as source or use temporary table as source)?
Thanks

if you use a Table as source for the intermediate process, it will create a physical temporary table i your work rep(depends on you choice) and populate the data into the table. if you use a interface as a source, just it will create a sub query instead of temporary table.
Thanks

Difference between conversion id and correlation id in bpel

Hi All,
In invoke/receive/pick activity, there are two options. one for conversion id and one from correlation id. I know the purpose of correlation id in these activities. But donot know what is the difference between both.
Are both having same functionality or something overlapping.

Difference between serial & ethernet interface.

Hi every one,
i have some doubts in basic stuffs.
Q1: What are the differences between serial interface and ethernet interfaces.
Q2: Can we use ethernet interfaces to terminate WAN connectivity just like serial.Why always we are using serial interfaces to connect the WAN.
Please help me out by answering these questions.
!!!!THANKS IN ADVANCE!!!!!

Hi There,
   Good explanation by Navin.
   On top of that, Serials are by nature flexible and it can be comfortably devided like per customer or provider needs from T1 or E1 connection.
   So the Bandwidth allowed to have physical pipe can be clearly configured and adjusted because of TDM structure each T1 or E1 is multiples of 64 kbps slots ( example :- 64 x 32 fpr E1 which 2048 Kbps or 2 Mb circuit) same follow for T1. This is good to have exactly what we run when designing Layer 3 Routing, so Routing protocols can take Routing decisions based on Bandwidth provisioned automatically or adjust with Policy based Routing.
   When it comes to FastEthernet the original build was for LAN connectivity. Of course we can use for MAN or WAN because of multilayer aware of transmissions capability is already rocking in Market. Because of Switching and Routing enhancements ( merge ) and many devices are aware of Layer 2 to 7 traffic patterns in many vendors. So it is difficult to clearly define the scope for these two types these days.
   Hope you got some clarification !
   Happy Reading

Difference between interfaces in Java API and user defined interfaces

Is there any differences between the interfaces (such as KeyListener, ActionListener and EventListener etc.,) in Java API and the user defined interfaces.
The user defined interfaces seems to be empty without any functionality (except its constant and method declarations). But the interfaces in Java API seems to have some functionality behind them, since they route the device events to the programs.
Actually what is happening behind the Java API's interfaces?
Please clarify.

Ummm, no they are not (or at least some of them are not). Also, some things we support now we may not have supported in a previous release.
If you look at the section 2 (Working with TimesTen Data Stores0 in the TimesTen Java Developer's Guide and look at the sections:
TimesTen JDBC Extensions
Additional TimesTen classes and interfaces
then you will see the extra functionality documented there. Of course, if you do not need any of this functionality then you can simply treat them as the base classes from java.sql and they will work fine so it is easy to make most of your code generic.

Are there any differences between using Adobe Illustrator on a MAC and on a PC?

Hello,
I'm about go enroll in a class specialized for teaching Adobe Illustrator in order to be able to use the program at work. The company that I work at uses Macintosh computers to deal with clerical work and everything, so I would like to know if there are any differences between using Adobe Ilustrator on a MAC and on a PC. The school that offers training teaches two types of classes, where one uses Illustrator on a MAC, and the other one on a PC. The PC class is able to have an earlier start date, which is why I'm sort of leaning towards choosing that class as I need to be able to use the software as soon as possible, but if there are main differences between the interface that will affect my knowledge of using Illustrator on a MAC after I take the class with Windows systems, then I will most likely be waiting for the class teaching in MAC systems.
Thanks in advance for the help!
Oh and another suggestion- should I take the Illustrator class in CS6 or CS5?

Reading through the CS5 vs CS6 performance thread, the Mac version seems to have worse performance than Windows version. From a starter's perspective the differences would most likely never be realized. It will take some time to see differences between even CS5 and CS6 other than the visual aspect of course.
Definitely take the CS6 versionso you can say you have it. CS5 is my preferred version, CS6 is garbage with the bugs it has for the type of work I use it for.
