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.
Regards,
Sunil

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

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

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).

What is the difference between conversion and interface?

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.

It is the decode statement that is doing this.
The format of decode is:
decode(expression, search1, result1, search2, result2, searchn, resultn, default)
All result fields must be of the same datatype and will be of the datatype of the first result (result1 in this example)
In your example (the decode for the field Days) the first result is a NULL. I suspect (gurus? anyone?) that Oracle will use the varchar2 overload of the decode statement, and the date field will be converted to varchar2 using your NLS_DATE_FORMAT settings.
In the second decode statment (Day1) the first result is of datatype date, so the result of the decode statement will be a date field (and will be parsed as such by your sql development tool)
I agree, as NULL is the first result returned the datatype is undetermined, so Oracle is picking VARCHAR2 over others, and causing an implicit datatype conversion on the resultant date value, whereas the other which is returned as a date will use the local settings of the client tool being used.
I can replicate the 'issue' in Toad, and it's rectified if we cast the first returned value of the decode statement...
SELECT DECODE ('I', 'I', DECODE (1, NULL, CAST(NULL AS DATE), 0, NULL, SYSDATE + 1)) Days,
DECODE ('I', 'I', SYSDATE + 1) Day1

Differences between PDF (Interactive) and PDF (Print)

What are the main differences between PDF (Interactive) and PDF (Print)?
Now it seems to me that PDF (Interactive) is limited version of PDF (Print).
Any links to read about this topic?
Thank you in advance,
Mykolas

There's actually quite a few differences between (Interactive) and (Print).
Here's a list of pointers written by Michael Ninness (previous product manager of InDesign and now working at Lynda.com) http://www.lynda.com/michaelninness
I just got premission from him to post this (Thanks Michael!):
Here is some info for you regarding what choices are being made under the hood when you choose File > Export > Adobe PDF (Interactive).
Things that just happen or are included, with no choice in the dialog box:
Hyperlinks, Bookmarks, Fast Web view, Compress Text and Line Art, Crop Image Data to Frames.
Things that are not included, with no choice in the dialog box:
Visible Guides/Grids, Hidden and Non-Printing Layers, Hidden and Non-Printing Objects, Marks & Bleeds, No Ink Manager or Simulate Overprint options.
Things that you can choose:
Security Settings, Embed Page Thumbnails, Create Tagged PDF, Create Acrobat Layers, Initial View, Initial Layout, Open in Full Screen Mode, Page Transitions, Image compression and resolution.
Other:
Fonts: Subset 100%
Color Conversion: Destination
Destination: sRGB
Profile Inclusion Policy: Include Destination Profile
Transparency Flattener: No Flattening
And lastly, Compatibility is set to Acrobat 9 (PDF 1.7). This last point is important, and largely explains the main reason we split Interactive PDF out as a separate export choice from Print PDF. When you export an interactive PDF from CS5, included media is now written out to the Rich Media Annotation Layer, which means this content is played back via the embedded Flash Player within Acrobat Pro 9 or Adobe Reader 9 or higher. In previous versions, this content was written out to the Screen Annotation Layer, which meant this content was played back via QuickTime. This has been a long-standing headache for end users as playback across platforms was often inconsistent, would frequently break when Apple updated QuickTime, etc.
Lastly, if you want to include rich media in your interactive PDFs (SWFs, audio and video), the only formats supported if you want to target Adobe PDF (Interactive) are MP3 for audio and FLV for video. Other file formats will need to be converted to these formats before you export to Interactive PDF. For video files, you’ll be able to convert to FLV with Adobe Media Encoder. For audio files, you can use any number for free audio conversion tools, including iTunes.

Difference between RFC adapter and a proxy

Can any one tell me the technical difference between RFC adapter and a proxy?
reg

There are advantages / disadvantages for RFC / Proxies / Idocs. So if I am in your position depending upon the requirement I will choose one. Some of the differences are:
RFC and Proxy:
RFC/BAPI has its own overhead of function call.
Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.
ABAP Proxies uses Webservice and Http Protocols.
If you use ABAP Proxy , you can reduce the overhead calling the function again and again.
Proxy and Idoc:
IDOC : After recieving the strucutred data It processes it using a Function Module associated with it.
Proxy : Proxy is a structure where there is no processing function module associated. You need to explicitly write the Business Logic/Call the subroutines here
This is my absolutely my view. Another guy has his own response. So first go through your requirements and then you can decide for what to go.
Also go through this urls which may help you:

Difference between relational integrity and data intigrity

hi
could anybody tell me
what is the difference between
relational integrity and data intigrity
tahnx
kals.

hi,
Data Integrity
Data integrity means, in part, that you can correctly and consistently navigate and manipulate the tables in the database. There are two basic rules to ensure data integrity; entity integrity and referential integrity.
The entity integrity rule states that the value of the primary key can never be a null value (a null value is one that has no value and is not the same as a blank). Because a primary key is used to identify a unique row in a relational table, its value must always be specified and should never be unknown. The integrity rule requires that insert, update, and delete operations maintain the uniqueness and existence of all primary keys.
The referential integrity rule states that if a relational table has a foreign key, then every value of the foreign key must either be null or match the values in the relational table in which that foreign key is a primary key.
What is a Relational Integrity?
A relational database contains tables of data which are related to each other. For example, articles are related to the author who wrote them, and conversely, authors are related to the articles they wrote. (Sounds obvious, and it is.) That's the relational part.
When we work with a relational database, we naturally expect that data in related tables stay related. For example, articles written by MartinB should always be related to MartinB and never be confused with articles written by any other author. That's the integrity part.
Relational Integrity is also called Referential Integrity, perhaps because the mechanism for ensuring integrity is implemented by the way the tables reference each other. Both terms are okay with me. I usually just say RI anyway.

What is the difference between ejb reference and ejb handle?

Hi:
I am newbie for J2EE.
I want to know what is the difference between ejb reference and ejb handle
from the client view and from the container view?
Very Thanks!
Stive

Hi John,,
1) Ejb Object Handle are nothing but a long lived proxy for the
ejb object, using this handle user can disconnect from the Ejb Server/Container
at any time
and after some time using the same handle he can able to resume the conversational
state
with the server / container where he was been disconnected From.
And there are currently two Handles , HomeHandle and Handle for EjbHomeObject
and EjbObject
Respectively. Both these handles have Persistent reference to the EJB Object
2) Ejb Reference is used to lookup a bean from other Enterprise Bean
Ejb reference is a nickname for the JNDI Location that you want to lookup a bean.
your code will looks up a Home object via using this nickname
and the deployer will bind the
nickname to the JNDI location of its choice
EJb Reference are declared in the deployment descriptor

Wht is the difference between unicode program and non unicode program ?

Hi guru,
wht is the difference between unicode program and non unicode program ?
Regards
Subash

About brief idea about unicode
In the past, SAP developers used various codes to encode characters of different alphabets, for example, ASCII, EBCDI, or double-byte code pages.
ASCII (American Standard Code for Information Interchange) encodes each character using 1 byte = 8 bit. This makes it possible to represent a maximum of 28 = 256 characters to which the combinations 00000000, 11111111 are assigned. Common code pages are, for example, ISO88591 for West European or ISO88595 for Cyrillic fonts.
EBCDI (Extended Binary Coded Decimal Interchange) also uses 1 byte to encode each character, which again makes it possible to represent 256 characters. EBCDIC 0697/0500 is an old IBM format that is used on AS/400 machines for West European fonts, for example.
Double-byte code pages require 1 or 2 bytes for each character. This allows you to form 216 = 65536 combinations where usually only 10,000 - 15,000 characters are used. Double-byte code pages are, for example, SJIS for Japanese and BIG5 for traditional Chinese.
Using these character sets, you can account for each language relevant to the SAP System. However, problems occur if you want to merge texts from different incompatible character sets in a central system. Equally, exchanging data between systems with incompatible character sets can result in unprecedented situations.
One solution to this problem is to use a code comprising all characters used on earth. This code is called Unicode (ISO/IEC 10646) and consists of at least 16 bit = 2 bytes, alternatively of 32 bit = 4 bytes per character. Although the conversion effort for the R/3 kernel and applications is considerable, the migration to Unicode provides great benefits in the long run:
The Internet and consequently also mySAP.com are entirely based on Unicode, which thus is a basic requirement for international competitiveness.
Unicode allows all R/3 users to install a central R/3 System that covers all business processes worldwide.
Companies using different distributed systems frequently want to aggregate their worldwide corporate data. Without Unicode, they would be able to do this only to a limited degree.
With Unicode, you can use multiple languages simultaneously at a single frontend computer.
Unicode is required for cross-application data exchange without loss of data due to incompatible character sets. One way to present documents in the World Wide Web (www) is XML, for example.
ABAP programs must be modified wherever an explicit or implicit assumption is made with regard to the internal length of a character. As a result, a new level of abstraction is reached which makes it possible to run one and the same program both in conventional and in Unicode systems. In addition, if new characters are added to the Unicode character set, SAP can decide whether to represent these characters internally using 2 or 4 bytes.
A Unicode-enabled ABAP program (UP) is a program in which all Unicode checks are effective. Such a program returns the same results in a non-Unicode system (NUS) as in a Unicode system (US). In order to perform the relevant syntax checks, you must activate the Unicode flag in the screens of the program and class attributes.
In a US, you can only execute programs for which the Unicode flag is set. In future, the Unicode flag must be set for all SAP programs to enable them to run on a US. If the Unicode flag is set for a program, the syntax is checked and the program executed according to the rules described in this document, regardless of whether the system is a US or an NUS. From now on, the Unicode flag must be set for all new programs and classes that are created.
If the Unicode flag is not set, a program can only be executed in an NUS. The syntactical and semantic changes described below do not apply to such programs. However, you can use all language extensions that have been introduced in the process of the conversion to Unicode.
As a result of the modifications and restrictions associated with the Unicode flag, programs are executed in both Unicode and non-Unicode systems with the same semantics to a large degree. In rare cases, however, differences may occur. Programs that are designed to run on both systems therefore need to be tested on both platforms.

Difference between LockSupport.parkUntil and Thread.sleep method

Hi
Could someone please explain the difference between LockSupport.parkUntil and Thread.sleep methods.
Thanks in advance.

javaLearner wrote:
The thing that I am trying to understand is - the difference / correlation between the two methods mentioned.
In the javadoc, there is a mention of correlation between the LockSupport methods park, unpark and the Thread methods suspend, resume - but not park and sleep.Then that suggests that there isn't any difference /correlation -- whatever you meant by that. Perhaps your question is like asking for the difference between a fish and a bicycle.
Also, I would like to understand the statement
These methods are designed to be used as tools for creating higher-level synchronization utilities, and are not in themselves useful for most concurrency control applications. (from the javadoc)Again, you're going to have to explain what you don't understand about it.

Main difference between 4.6c and ecc 5.0

Hi,
Please give me brief about difference between 4.6c and ECC 5.0
Thanks,
Asha

Hi Asha,
you can see in Tcode : UCCHECK .you modify the objects in unicode conversion.some functionality didn't support in ECC 5.0.
this is the brief documentation of that TCODE.
BAP Unicode Scan Tool UCCHECK
You can use transaction UCCHECK to examine a Unicode program set for syntax errors without having to set the program attribute "Unicode checks active" for every individual program. From the list of Unicode syntax errors, you can go directly to the affected programs and remove the errors. It is also possible to automatically create transport requests and set the Unicode program attribute for a program set.
Some application-specific checks, which draw your attention to program points that are not Unicode-compatible, are also integrated.
Selection of Objects:
The program objects can be selected according to object name, object type, author (TADIR), package, and original system. For the Unicode syntax check, only object types for which an independent syntax check can be carried out are appropriate. The following object types are possibilities:
PROG Report
CLAS Class
FUGR Function groups
FUGX Function group (with customer include, customer area)
FUGS Function group (with customer include, SAP area)
LDBA Logical Database
CNTX Context
TYPE Type pool
INTF Interface
Only Examine Programs with Non-Activated Unicode Flag
By default, the system only displays program objects that have not yet set the Unicode attribute. If you want to use UCCHECK to process program objects that have already set the attribute, you can deactivate this option.
Only Objects with TADIR Entry
By default, the system only displays program objects with a TADIR entry. If you want to examine programs that don't have a TADIR entry, for example locally generated programs without a package, you can deactivate this option.
Exclude Packages $*
By default, the system does not display program objects that are in a local, non-transportable package. If you want to examine programs that are in such a package, you can deactivate this option.
Display Modified SAP Programs Also
By default, SAP programs are not checked in customer systems. If you also want to check SAP programs that were modified in a customer system (see transaction SE95), you can activate this option.
Maximum Number of Programs:
To avoid timeouts or unexpectedly long waiting times, the maximum number of program objects is preset to 50. If you want to examine more objects, you must increase the maximum number or run a SAMT scan (general program set processing). The latter also has the advantage that the data is stored persistently. Proceed as follows:
- Call transaction SAMT
- Create task with program RSUNISCAN_FINAL, subroutine SAMT_SEARCH
For further information refer to documentation for transaction SAMT.
Displaying Points that Cannot Be Analyzed Statically
If you choose this option, you get an overview of the program points, where a static check for Unicode syntax errors is not possible. This can be the case if, for example, parameters or field symbols are not typed or you are accessing a field or structure with variable length/offset. At these points the system only tests at runtime whether the code is sufficient for the stricter Unicode tests. If possible, you should assign types to the variables used, otherwise you must check runtime behavior after the Unicode attribute has been set.
To be able to differentiate between your own and foreign code (for example when using standard includes or generated includes), there is a selection option for the includes to be displayed. By default, the system excludes the standard includes of the view maintenance LSVIM* from the display, because they cause a large number of messages that are not relevant for the Unicode conversion. It is recommended that you also exclude the generated function group-specific includes of the view maintenance (usually L<function group name>F00 and L<function group name>I00) from the display.
Similarly to the process in the extended syntax check, you can hide the warning using the pseudo comment ("#EC *).
Applikation-Specific Checks
These checks indicate program points that represent a public interface but are not Unicode-compatible. Under Unicode, the corresponding interfaces change according to the referenced documentation and must be adapted appropriately.
View Maintenance
Parts of the view maintenance generated in older releases are not Unicode-compatible. The relevant parts can be regenerated with a service report.
UPLOAD/DOWNLOAD
The function modules UPLOAD, DOWNLOAD or WS_UPLOAD and WS_DOWNLOAD are obsolete and cannot run under Unicode. Refer to the documentation for these modules to find out which routines serve as replacements.
cheers,
sekhar.

Difference between Heuristic SAP_SNP_SNGL and SAP_SNP_MULT

Hi,
Please explain me the functional difference between heuristic SAP_SNP_SNGL and SAP_SNP_MULT.
Regards
Syed

Dear Syed,
To convert Supply Network Planning (SNP) orders or Capable-to-Match(CTM) orders into Production Planning and Detailed Scheduling (PP/DS) orders, you use a heuristic based on the algorithm /SAPAPO/HEU_SNP_CONVERT, such as the standard heuristic SAP_SNP_SNGL.
You can implement the heuristic in the production planning run or in interactive planning. If you want to use the functions of the MRP heuristic in the production planning run for a high-performing mass conversion (bundling, parallel processing, and extended log), you call up the conversion heuristic using the MRP heuristic. The heuristic SAP_SNP_MULT is available as a combined standard heuristic.It is an MRP heuristic that calls up the SAP_SNP_SNGL heuristic.
SAP_SNP_MULT is a SNP-PP/DS conversion for many products:
You use this heuristic to perform a mass conversion of Supply Network Planning (SNP) orders into Production Planning and Detailed Scheduling (PP/DS) orders in the production planning run. This heuristic is an MRP heuristic that calls the heuristic SAP_PP_SNGL for the actual conversion.
SAP_SNP_SNGL is used in production planning run for conversoin.However, the conversion takes place with heuristic SAP_SNP_SNGL which is entered in the heuristic SAP_SNP_SNGL customizing.
Please also refer to online for more details on this...
