What are Application and System Erros

Hi Team
I am unable to understand what are the Application Errors and System Errors???
Could you please explain the difference between them and when we will encounter them?
thanx in advance.

What are application events and system events? what is difference between ?

what are application events and system events? what is difference between ?

The Control Framework triggers the event irrespective of the screen flow logic, that is, without processing the PAI and PBO events. These events are called system events. This type of event processing is the default setting.
·The Control Framework processes the PAI module after an event. In this case, you must call method CL_GUI_CFW=>DISPATCHto initiate the event handling of ABAP Objects. These events are called application events.
Application Event : you must first register the events for the control instance and consequently on the frontend.
like..
DATA events TYPE cntl_simple_events.
DATA wa_events TYPE cntl_simple_event.
1. Using field
appl_event , define the event as an application event:
wa_events-appl_event = 'X'.
System events are passed on irrespective of the flow logic of the relevant screen.
1. Change the value of field
wa_events-appl_event in the PBO module:
wa_events-appl_event = SPACE.

What are strengths and weaknesses of the sap.m.Shell and sap.m.App as container for an application wrapper?

My question today: What are strengths and weaknesses of the
sap.m.Shell
and
sap.m.App
as container for an application wrapper?
I currently use non of them, but I see the advantages.
SAP best practise is to use one of them or nest them as shell > app. What are strengths and weaknesses of the approaches?

We prefer to say, the tender mercies of the Fetch block.
You'll notice the "wfm info" cluster as an output of the Fetch
VI. This cluster has gain and offset members- use these to scale
your binary data to floating point voltage representation.
As you point out, the numbers won't be exactly what you expect given
the vertical range and the device resolution. There are a few
reasons for this. First, we don't use the absolute full scale of
the ADC for the maximum input voltage. There are a couple of
codes of headroom at the top and bottom. This allows your input
signal to slightly exceed the specified vertical range without clipping
(you'll get a warning from the driver). Second, these gain and
offset numbers take into account calibration information for your
device. Using these numbers will correct for small deviations
from the ideal offset and gain.
So if you use the gain and offset numbers from the driver, your
measurements will be more accurate than if you assume 0 offset and
perfect gain. They will be most accurate if you make sure to
perform a self-calibration once the device is in your system and at the
temperature that your tests will be run.

ABAP System Fields
ABAP system fields are always available in ABAP programs. The runtime system fills them according to context. They can then be used in programs to query the system status. System fields are variables but you should always treat them as though they were constants, and only read them. If you change their values, important information for the flow of the program may be lost. In exceptional circumstances, system fields may be overwritten in an ABAP program to control the system for example, SY-LSIND (for navigating to a detail list).
With one exception the names and data types of the system fields are stored in the ABAP Dictionary in the SYST structure and realized as components of the predefined structure SY in ABAP programs.
The system field SY-REPID is not part of SYST or SY. Instead, every program contains the predefined constants SY-REPID and SYST-REPID, which both contain the name of the corresponding program. Furthermore, there are two predefined types of the same name, SY-REPID and SYST-REPID.
All system fields are addressed using SY field name and their types using SYST field name.
                                                                                Alphabetical Overview
The following table lists the definitions of the structure SYST in the ABAP Dictionary alphabetically. The character in the first column indicates how you can use the corresponding system field in ABAP programs. Name is the name of the component, Type is the Dictionary data type, and Length is the field length defined in the Dictionary. The Use column shows in which environment the system fields are set. The Description indicates the content.

SY-UNAME
Logon name of user, for example KELLERH, BC400-01.
Date and Time Information
The following system fields are always set automatically. If necessary, the GET TIME statement synchronizes the application server time with that of the database server and writes it to the system field SY-UZEIT. SY-DATUM and the system fields for the local time zone, that is SY-TIMLO, SY-DATLO, and SY-ZONLO are also reset.
SY-DATLO
Local date of user, for example 19981129, 19990628.
SY-DATUM

SY-CALLD contains SPACE if the program is the first and only program in a call chain. SY_CALLD contains 'X' if the program is a called program in a call chain (see ABAP Calls Overview).
·        SY-CALLD is set to X in a program called using CALL TRANSACTION, CALL DIALOG, or SUBMIT AND RETURN.
·        SY-CALLD is set to SPACE in a program called using LEAVE TO TRANSACTION, entering a transaction code on a screen, and processing batch input folders.
·        With SUBMIT (without RETURN) SY-CALLD retains the previous value.
SY-CPROG
In externally called procedures, the name of the calling program, otherwise the name of the current program. If an externally called procedure calls another external procedure, SY-CPROG keeps the name of the first main program and is not given the name of the main program of the further caller.
SY-DBNAM
With executable programs this is the linked logical database.
SY-DYNGR
Screen group of current screen. You can assign several screens to a common screen group. You can use this, for example, to modify all of the screens in the group in a uniform way.
SY-DYNNR
Number of current screen During the selection screen processing, SY-DYNNR contains the screen number of the current selection screen. During list processing, SY-DYNNR contains the number of the container screen. While a subscreen is being processed, SY-DYNNR contains its screen number. This also applies to tabstrips.

SY-REPID
Name of current ABAP program. With externally called procedures this is the name of the procedures main program.
If SY-REPID was transferred to an external procedure as an actual parameter before Release 6.10, the formal parameter was not given the name of the caller, but the name of the procedures main program. SY-REID had to be transferred to an auxiliary variable before the call or you had to use SY-PROG.
As of Release 6.10, SY-REPID is a separate constant that is no longer part of the structure SYST or SY. It can be transferred to external procedures directly.
SY-TCODE
Name of current transaction code.
Background Processing
SY-BATCH
SY-BATCH is set to X in an ABAP program running in the background. Otherwise it is empty.
Batch Input
SY-BINPT
SY-BINPT is set to X during processing of batch input folders and in ABAP programs called with CALL TRANSACTION USING. Otherwise it is empty.
·         OPTIONS FROM in the CALL TRANSACTION USING statement can set SY-BINPT to empty for the whole program execution, as well as at the end of the BDC data.
·         In CATT procedures, SY-BINPT is always empty.
                                                                                ABAP Programming
Constants

Contains the Alphabet. Can be used to access individual letters independently of the codepage by specifying offset.
SY-ULINE
Contains a horizontal line with length 255. Can be used when creating the list.
SY-VLINE
Contains a vertical line (|). Can be used when creating the list
Loops
SY-INDEX
SY-INDEX contains the number of loop passes in DO and WHILE loops, including the current loop pass.
Character Strings
SY-FDPOS
Found location for operations with character-type fields.
·        If the operators CO, CN, CA, NA, CS, NS, CP, NP are used in comparisons, SY-FDPOS is assigned offset values depending on the comparison result.
·        SEARCH FOR sets SY-FDPOS to the offset of the found search string.
Internal Tables
SY-TABIX
Current line in an internal table. With the following statements SY-TABIX is set for index tables. With hashed tables, SY-TABIX is not filled or it is set to 0.
·        APPEND sets SY-TABIX to the index of the last table row, that is the total number of entries in the target table.
·        COLLECT sets SY-TABIX to the index of the existing or appended table row. With hashed tables, SY-TABIX is set to 0.
·        LOOP AT sets SY-TABIX to the index of the current table row at the beginning of every loop pass. After leaving a loop, SY-TABIX is set to the value it had before entering the loop. With hashed tables, SY-TABIX is set to 0.
·        READ TABLE sets SY-TABIX to the index of the table row read. If no row is found with binary search while reading, SY-TABIX contains the index of the next-highest row or the total number of rows +1. If no row is found with linear search while reading, SY-TABIX is undefined.
·        SEARCH 0). Each time an interactive list event occurs, the system automatically increases SY-LSIND by 1. SY-LSIND can be changed in the ABAP program to navigate between detail lists. Changes to SY-LSIND are not taken into account until the end of the list event. Therefore, any manipulation of SY-LISND should be done using the last command of the processing block.
SY-LSTAT
ID for list levels within the program. SY-LSTAT can be filled with values during list creation in the ABAP program. The value valid when the list is completed is saved with the list. In the case of an interactive list event, SY-LSTAT is set to the value it was assigned during the creation of the list from which the event takes place. SY-LSTAT is no longer maintained and should therefore no longer be used.
SY-STACO
Number of the first displayed column of the list from which the event was triggered. Counting starts at 1.
SY-STARO
Number of the upper-most displayed row of the upper-most page of the list, from which the event was triggered. Counting begins at 1. This does not include the page header.
Printing Lists
When printing lists, the spool and runtime systems require certain internal information, which is available in the following system fields and is set during print activation.
SY-CALLR
Contains a value that displays where printing was started, for example NEW-PAGE for program-controlled printing or RSDBRUNT for printing from the selection screen.
SY-PRDSN
Contains the name of the spool file during printing.
SY-SPONO
Contains the name of the spool number during printing.
SY-MAROW, SY-MACOL
The SET MARGIN statement fills the system fields SY-MAROW and SY-MACOL, which determine the number of lines on the upper margin and the number of columns on the left margin when printing.
Print Parameters
The print parameters are transferred to the spool system by the runtime system in a structure of dictionary type PRI_PARAMS. Before this structure was used, its purpose was served by system fields. Today a subset of the PRI_PARAMS structure is still written to system fields with the same names when printing is activated. This information is redundant and should not be used.
Messages
If you execute the MESSAGE statement, the following system fields are set. If you execute the MESSAGE RAISING statement in function modules and methods, these fields are also set in the calling program, if it handles the exception.
SY-MSGID
SY-MSGID contains the message ID.
SY-MSGNO
SY-MSGNO contains the message number.
SY-MSGTY
SY-MSGTY contains the message type.
SY-MSGV1,,SY-MSGV4
SY-MSGV1 to SY-MSGV4 contain the field contents that are used for the messages placeholders.
Special Actions that Fill Message Fields
·        If you request database locks using the ENQUEUE function module, the field SY-MSGV1 contains the name of the user who holds the lock, in the case of the FOREIGN_LOCK exception.
·        IN the case of CALL TRANSACTION or CALL DIALOG with the USING addition, a message displayed during the called screen sequence is returned in the fields SY-MSGID, SY-MSGTY, SY-MSGNO, SY-MSGV1, ... , SY-MSGV4.
·        During Remote Function Call (RFC), error messages are transferred from the remote system to the calling system and SY-MSGID, SY-MSGTY, SY-MSGNO,SY-MSGV1, SY-MSGV2, SY-MSGV3, SY-MSGV4 are set. If short dumps or type X messages occur, the system also sets the fields.
                                                                                Internal System Fields
Internal system fields are only for internal use in the ABAP runtime environment and are defined in the kernel. Under no circumstances must they be overwritten in ABAP programs and they should also not be read (processed).

I'm now filling the installation parameter sheet of SCM(APO) system.
This sheet has two paraemters whose content I'm not sure of.
That is, software units SCMRWBS and SCMEMWCL.
What are SCMRWBS and SCMEMWCL for ?
Do we need to install them while my project will use PP/DS and BP modules ?
And can we see whether these usage types installed or not via SAPGUI ?
I beg your help !
Thank you for your cooperation in advance.
Regards,

Hi Hideki,
SCMRWBS is for SCM Replenishment Workbench. If you are using F&R modules of mySAP SCM suite, then this component is neccessary.
Smilarly, SCMEMWCL is SCM Web Communication Layer for Event Management. Again this is part of mySAP SCM, but belongs to Event Management module.
As far as PP/DS is concerned these two components are not neccessary. However, these components may have some dependencies on other applications / modules. Please check with SAP for any specific inputs if you have any concern over installing them onto your system.
Thanks,
Rajesh

0.41GB of my iPod Touh 4G' is taken up by something called 'Others'. What are 'Others' and can they be deleted or are they an essential part of the iPod and embedded in it? If not essential how do I go about deleting it to enable me to add other pictures

0.41GB of my iPod Touch 4G's capacity is taken up by something callked 'Others'. What are 'Others' and will it be o.k to delete them? If so how do I go about doing it as there is no trace of a file on either iTunes or my iPod?

Other content is typically miscellaneous data used by applications you have installed - could be save data (e.g. for games), or documents you've created. There's no easy way to determine precisely what it is, but the only way to clear it is to either delete it from within the respective application, or remove the associated application altogether - neither of which are typically practical.

What are the minimum system requirements for GB 4?

What are the minimum system requirements for GB 4? I did search this forum but wasn't able to find a direct answer.
I'm running version 3.0.4 successfully on a lowly G4 733 but I suspect this is as far as I can go.
I'm updating to iDvd'08 and was also wondering if I can safely update to GB4 or not (from GB 3.0.7) on a G4 733 mhz Digital Audio. Any help would be sincerely appreciated. My guess is that I cannot but I'd like to confirm prior to attempting any further updates in GB.

I try my best to play it safely; always. And you were right, everything worked on the ext. FW HD flawlessly ...... truly amazing software!
(I did happen to check the activity Monitor w/in Utilities and it showed GB4 using about 60-67% of the CPU on a G4 733 ..... I'm assuming this is normal).

Not sure if there's a correct order to opening these apps as there has been in former versions of iLife ..... however, this (as shown above) is the order in which I opened all apps, and all worked well.

How can you change the font size in the application and system headers?

How can you change the font size in the application and system headers? I searched the system and finder prefs to no avail. Changing the screen density is not a good option.
Thanks

I downloaded Tinkertool. Found the font section and increased the size of most selections. The only thing that changed that I can see is the window label. The apple line, bookmarks line, the tool bar in safari are all the same---font size of about 4. Found the finder "show view options" but that didn't seem to change anything either. I'll keep working. Restarted all apps after changes as well.

What Are Application Keywords in Snow Leopard?

I recently updated to Snow Leopard, and I've been trying out the expanded syntax coloring. However, I cannot find one example of code colored as an application keyword.
I set the color for application keywords to bright red so it would stand out. I have hundreds of AppleScripts to test, and I have opened about half of them. Not once was any code colored as an application keyword. There were classes, properties, enumerations, parameters, commands, etc., but no application keywords.
So, what are application keywords in Snow Leopard? I thought I knew, but now I have no idea.
Any ideas?
Thanks
Brett

Thanks for the info. The 10.6 changes documentation says:
*Syntax coloring for scripts now has much more detail: commands, parameters, classes, properties, and enumerated values all have their own category now, instead of sharing the “application keywords” category, and may be formatted differently depending on whether they come from an application or a scripting addition.*
Does that mean all application keywords are now in different categories? If so, why is there an application keywords option in the syntax coloring prefs?
Thanks
Brett

What are valid and invalid email address characters

What are valid and invalid email address characters in Exchange 2010, for example can you have Conan.O'[email protected] is there a document that shows the valid and invalid sysmbols?

Hi
The format of email addresses is
local-part@domain where the local-part may be up to 64 characters long and the
domain name may have a
maximum of 253 characters - but the maximum 256 characters length of a forward or reverse path restricts the entire email address to be no more than 254 characters.[1]
The formal definitions are in RFC 5322 (sections 3.2.3
and 3.4.1) and RFC 5321 - with a more readable form given in
the informational RFC 3696[2]
and the associated errata.
Local part
The local-part of the email address may use any of these
ASCII characters
RFC 5322 Section
3.2.3:
Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
Digits
0 to
9 (ASCII: 48-57)
Characters
!#$%&'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 94-96, 123-126)
Character
. (dot, period, full stop) (ASCII: 46) provided that it is not the first or last character, and
provided also that it does not appear two or more times consecutively (e.g. [email protected] is not allowed.).
Special characters are allowed with restrictions. They are:
o
Space and
"(),:;<>@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 91-93)
The restrictions for special characters are that they must only be used when contained between quotation marks, and that 3 of them (The
space, backslash \ and
quotation mark " (ASCII: 32, 92, 34)) must also be preceded by a backslash
\ (e.g.
A quoted string may exist as a dot separated entity within the local-part, or it may exist when the outermost quotes are the outermost characters of the local-part
(e.g. abc."defghi"[email protected] or
"abcdefghixyz"@example.com are allowed. Conversely,
abc"defghi"[email protected] is not; neither is
abc\"def\"[email protected]). Quoted strings and characters however, are not commonly used.
RFC 5321 also
warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".
The local-part "postmaster" is treated specially - it is case-insensitive, and should be forwarded to the server's administrator. Technically all other local-parts
are case sensitive, therefore [email protected] and [email protected] specify different mailboxes. However most organizations treat uppercase and lowercase letters as equivalent, and also do not allow use of the technically valid characters
(space, ? and ^). Organizations are free to restrict the forms of their own email addresses as desired, e.g.,
Windows Live Hotmail,
for example, only allows creation of email addresses using alphanumerics, dot (.), underscore (_)
and hyphen (-).[3]
Systems that send mail must be capable of handling outgoing mail for all valid addresses. Contrary to the relevant standards, some defective systems treat certain
legitimate addresses as invalid and fail to handle mail to these addresses. Hotmail, for example, refuses to send mail to any address containing any of the following standards-permissible characters:
!#$%*/?^`{|}~
Domain part
The domain name part of an email address has to conform to strict guidelines: it must match the requirements for a
hostname,
consisting of letters, digits, hyphens and dots. In addition, the domain part may be an
IP address
literal, surrounded by square braces, such as jsmith@[192.168.2.1], although this is rarely seen except
in email spam.
Examples
Valid email addresses
<tt>[email protected]</tt>
<tt>[email protected]</tt>
<tt>[email protected]</tt>
<tt>much."more\ unusual"@example.com</tt>
<tt>very.unusual."@"[email protected]</tt>
<tt>very."(),:;<>[]".VERY."very@\\\ \"very"[email protected]</tt>
Invalid email addresses
<tt>Abc.example.com</tt> (an @ character must separate the local and domain parts)
<tt>[email protected]</tt> (character dot(.) is last in local part)
<tt>[email protected]</tt> (character dot(.) is double)
<tt>A@b@[email protected]</tt> (only one @ is allowed outside quotation marks)
<tt>a"b(c)d,e:f;g<h>i[j\k][email protected]</tt> (none of the special characters in this local part
is allowed outside quotation marks)
<tt>just"not"[email protected]</tt> (quoted strings must be dot separated, or the only element making
up the local-part)
<tt>this is"not\[email protected]</tt> (spaces, quotes, and backslashes may only exist when within
quoted strings and preceded by a slash)
<tt>this\ still\"not\\[email protected]</tt> (even if escaped (preceded by a backslash), spaces, quotes,
and backslashes must still be contained by quotes)

What are Conversions and Extensions

Hey ,
I want to know what are Conversions and Extensions. Can i get any material where i can get information on these.
Thanks in advance

The conversion programs were used to take the extract data from the legacy system and re-format for SAP and load the data into SAP.
Conversions are one-time programs used to transfer data from the legacy system into SAP. For example, you can transfer master data like vendors, customers etc.
SAP provides enhancement to BAPIs thru EXTENSION IN AND EXTENSION OUT .these are structure parameters.suppose example: one BAPI released to update the mara table.then u modified the table mara thru append structure.this changes will not be reflected in BAPIs.So thats why in that case we have to use EXTENSION IN AND EXTENSION OUT structures to fill and work.

What are Validation and simulator

can any one explain what are Validation and Simulators are ???
what is there importance and how they work in SAP ??
Regards,
Milindkumar

Are you referring to validation rules and simulations? Whereby validations allow the checking of values and combinations of data as they are being entered in SAP. Because the data is validated before it is posted, only correct information enters the system. For example if you have a cost center X that should not post to account Y. You create a validation that checks to see if cost center X is entered whether the account is Y. If the account is Y the validation will stop the entry from being made.
Simulations normally are when data is checked for accuracy or verfied before posting. Simulations usually allow the verification of data by displaying that entries that will post or will be created only after the post button or process occurs.

What are these and what are they useful for?: and

I have seen these symbols being used in Java: << and >>, what are they and what do they do?
Thank you.

As DrQuincy asks how is this of use over multiplying
and dividing?In your processor there are often different instructions for shifting, multiplying, and deleteing. Typically the shifting instructions take less time to execute and so using the shifting operator will be faster than multiplying. This assumes the compiler doesn't recognize the situation and optimize it out though.
The >>,<<,>>>, &,|,and ^ operators are mainly useful when you need to deal with individual bits of data. For instance if you are talking to another system (thats not java) that uses a different method of storing numbers (little endian/big endian etc.), or doing something such as creating parity data for error correction. There are lots of things to do, but most a low level and its rare when you need to use them.

What is a gateway proxy?? what are synchronous and asynchronous calls?

bapis are rfc enabled. but are there any other rfc's available in sap? what is a gateway proxy?? what are synchronous and asynchronous calls?

Hello:
Lets st art at the beginning.
There are NO documented viruses that affect a Mac running OS X - none (there are instances of Malware).

This is a Youtube video that explains what you have (I assume you installed it somehow) on your computer:
http://www.youtube.com/watch?v=JwRi2me2hSk
For openers, I would uninstall any A/V software you have put on your system. It is certainly possible that that junk has put some other stuff on your computer.
I'm also afraid my computer might have been hacked?
Highly unlikely.

What are Struts and how it is used in SAP

Hi
can anyone give a idea that what are struts and how it is used in SAP
Regards
JM

Hi John,
In this case google.com really us your friend - Struts is not an SAP technology, rather it is an MVC development paradigm (love using that word for Java. There are lots of useful websites with generic information around struts as well as a number of good books available from Amazon for instance.
As far as Struts and SAP goes - SAP use Struts for their Internet Sales CRM Webshop application. Of course, like anything else from SAP it has been modified slightly but is essentially the same.
