What is the purpose of Defining a requirement in the procedure?

Hi
I have a query related to the Output type .
What is the purpose of Defining a requirement in the procedure?
And where shall we code for a new requirement and also what shall we code in it?
Thanks

Requirement Use
If the requirement is fulfilled (SY-SUBRC = 0), then output determination also takes into consideration output type or the access sequence, for which the requirement has been specified.
Output determination:
An object that checks whether the application data (for example, data determined in Customizing) corresponds to the condition records.
If this is the case, one or several messages are "found," which can then be processed (for example, sent electronically).
The condition records are searched for according to a predefined hierarchy in message determination.
After defining a new requirement no say 604 for billing pricing procedure and activating it, the standard sap system creates a routine with the no: 604 specifically for billing. So the name of the program automatically created by SAP will have the naming convention something like RV64A604. then you need an access key to go to the change mode for writing any logic. Then just put a break-point and then execute VF01 or VF04, then the cursor position directly goes into this routine, where the pricing structures KOMK and KOMP have the visibility. So based on the values flowing inside this structures, you can probably code that suites the business requirements.
there are some useful transactions like VOFM for maintaining the requirements and formulaes for a pricing procedure.
For viewing the requirements in the procedure you can also go to V/08 transaction.

What is the purpose of standby redo log files

Hi,
What is the purpose of the standby redo log files in DR?
what if the standby redo log files are created? or else not created?
Please explain
Thanks

3.1.3 Configure a Standby Redo LogA standby redo log is required for the maximum protection and maximum availability modes and the LGWR ASYNC transport mode is recommended for all databases. Data Guard can recover and apply more redo data from a standby redo log than from archived redo log files alone.
You should plan the standby redo log configuration and create all required log groups and group members when you create the standby database. For increased availability, consider multiplexing the standby redo log files, similar to the way that online redo log files are multiplexed.>

What is control tables in abap hr?what is the purpose?

what is control tables in abap hr?what is the purpose?

These are the screen elements used to display tabular data they can be called
as screen tables( like STEP LOOP).To use table control we have to create it on the screen using SCREEN PAINTER(SE51) and declare a control variable of TYPE TABLEVIEW using CONTROLS statement in the ABAP program. We have to use LOOP .. ENDLOOP statement in both PBO and PAI with or without AT int_table parameter. IF AT int_table parameter is not used than we have to place a MODULE call between the LOOP...ENDLOOP statement to fill the screen table rows from the ABAP program in PBO and program our own scrolling functions
using OK_CODE field.
Having a parallel loop(at screen table rows & int table rows) by using parameter
AT int_table makes the ABAP code simple.
A special structure of type CXTAB_CONTROL is used to set/get various
attributes of table control at runtime like CURRENT_LINE ,TOP_LINE.
ABAP declaration
CONTROLS: tab_con TYPE TABLEVIEW USING SCREEN nnnn
Here tab_con is the same name we used in screen for the table control.
This ABAP statement will declare a control variable that will be used to access
the table control , and set it's various attributes like number of fixed columns(tab_con-FIXED_COLS) ,total number of records it will display(tab_con-LINES).It is of type CXTAB_CONTROL and is a deep structure(structure containing structures).
REFRESH CONTROL tab_con FROM SCREEN nnnn
This ABAP statement will initialize the table control on the screen nnnn to its initial values.
PBO processingI
n PBO we have to use the screen LOOP ...ENDLOOP statement , with or without
intenal table.
LOOP WITH CONTROL tab_con.
MODULE fill_tab_con.
ENDLOOP.
Here a module should be called between the loop endloop statement to transfer
data from th ABAP program to the screen table through a structure.This module
should use the CURRENT_LINE attribute of the table control variable to get the
current screen table record index to read the data from the internal table into a work area.
e.g.
READ TABLE int_table INDEX tab_con-CURRENT_LINE
The record read will be placed in the header line of the internal table and will be available to the similarly named screen fields or if these are different it can be written explicitly. e.g.
screen_field_name = int_table-field_name
LOOP AT int_table INTO workarea WITH CONTROL tab_con CURSOR i FROM
n1 TO n2.
ENDLOOP.
Here the module call is not required to fill the screen table.The CURSOR parameter is a integer of type I indicating which absolute internal table line
should be the first to display on the table control .FROM n1 TO n2 can be used
to restrict the starting line and ending line number of the internal table , they are of type SY-TABIX.
In both cases before the LOOP statement a module should be called which
is generally for setting of status ,in which we should fill the LINES attribute
(tab_con-LINES ) of the control with the total number of internal table records,doing this ensures correct and automatic scrolling.
The ABAP statement DESCRIBE TABLE int_table LINES lines can be used
to get the total lines in an int table.
PAI Processing
We have to use LOOP ... ENDLOOP in PAI so that data can transfer fro table control to ABAP program. If we want to write changes to the data we should
call a module between the LOOP ... ENDLOOP. The MODULE call to process user commands (SY-UCOM) should be called after the ENDLOOP statement.
e.g.
PROCESS AFTER INPUT
MODULE mod AT EXIT-COMMAND.
LOOP AT itab_table or LOOP "depending on whether we are using AT int_table
MODULE modify_int_table.
ENDLOOP.
MODULE user_command.
In the MODULE call modify_int_table we can use
MODIFY int_table FROM workarea INDEX tab_con-CURRENT_LINE
or we can use
int_table-field_name = screen_field_name.
Thanks
Please Reward points if helpful.

What is the purpose of having 'oracle' user with umask 022?

Hello,
What is the purpose with having the 'oracle' profile with a umask of 022? Isn't that a security risk having files created by 'oracle' with 755 permission? I mean why let others have the capability to read and execute on files that 'oracle' writes. Thank you.
Paul

Hi;
You can set it as you wish. But from note:
The umask utility sets the file mode creation mask of the current shell execution environment to the value specified by the mask operand. This mask affects the initial value of the file permission bits of subsequently created files. If umask is called in a subshell or separate utility execution environment, such as one of the following:
+(umask 002)+
nohup umask ...
find . -exec umask ...
it does not affect the file mode creation mask of the caller's environment. For this reason, the /usr/bin/umask utility cannot be used to change the umask in an ongoing session. Its usefulness is limited to checking the caller's umask. To change the umask of an ongoing session you must use one of the shell builtins.
If the mask operand is not specified, the umask utility writes the value of the invoking process's file mode creation mask to standard output.
The most common umask values are 022, 027, and 077. A umask value of 022 lets the owner both read and write all newly created files, but everybody else can
only read them:
Oracle recommended(also its a prereq for installation) to set umask 022 due to do upper explanation.
http://docs.oracle.com/cd/E19253-01/816-5165/umask-1/index.html
Regard
Helios
Source:
+0666 Default file creation mode+
+022 resultant mode+
+0644 resultant mode+
On many UNIX systems, the default umask is 022. This is inherited from the init process, as all processes are descendants of init.

What's the purpose for the two Wireless Antennas on a WAP?

I have a very simple question, that I'm a little confused about. Here it goes.
Most Access Points have two antennas. One is labeled as LEFT/PRIMARY and the other is RIGHT.
What is the purpose for the two antennas? When I have one antenna connected it works without any issues. Can I just use the LEFT/PRIMARY antenna for wireless connectivity? What are the purpose for the two?
And we are talking about a single band, 802.11b/g NOT 802.11a.
Thank you!

Hi Rashida,
The use of two Antennas on these AP's is used for "Diversity Mode. In many cases, 1 single Antenna will work nicely. Here is an explanation for the use of two Antennas :)
This describes the use of 2 **Identical Antennas in "Diversity" Mode;
The purpose of diversity is to overcome multipath reflections. Diversity antennas that share the same physical housing are placed at an optimum distance apart. The maker of the particular antenna determines that distance based on the characteristics of the antenna. When you use a pair of antennas with matching characteristics to provide diversity for cell coverage in your facility, the guideline is to put those matched antennas at a distance apart from each other that is equal to a multiple of the wavelength of the frequency that is being transmitted. The 2.4 GHz wavelength is approximately 4.92 inches. Therefore, to support diversity on a 2.4 GHz radio with two separate antennas, the antennas should be spaced approximately 5 inches apart. The antenna pair could also be spaced at multiples of 5 inches, but the distance between should not exceed 4 multiples: reflected waves farther apart than that are likely to be so distorted and different in delay spread that the radio could not work with them.Because each antenna is selected by itself, both antennas must have the same radiation characteristics and be positioned to provide similar cell coverage.
**** Two antennas connected to the same access point must not be used to cover two different cells.****
From this good doc;
Multipath and Diversity
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008019f646.shtml
A diversity antenna system can be compared to a switch that selects one antenna or another, never both at the same time. The radio in receive mode will continually switch between antennas listening for a valid radio packet. After the beginning sync of a valid packet is heard, the radio will evaluate the sync signal of the packet on one antenna, then switch to the other antenna and evaluate. Then the radio will select the best antenna and use only that antenna for the remaining portion of that packet.
On transmit, the radio will select the same antenna it used the last time it communicated to that given radio. If a packet fails, it will switch to the other antenna and retry the packet.
One caution with diversity, it is not designed for using two antennas covering two different coverage cells. The problem in using it this way is that, if antenna no. 1 is communicating to device no. 1 while device no. 2 (which is in the antenna no. 2 cell) tries to communicate, antenna no. 2 is not connected (due to the position of the switch), and the communication fails. Diversity antennas should cover the same area from only a slightly different location."
Diversity Antenna Systems
Diversity antenna systems are used to overcome a phenomenon known as multipath distortion of multipath fading. It uses two **identical antennas, located a small distance apart, to provide coverage to the same physical area.

1. What's the difference between private mode in Safari which i have to turn on every time again when opening safari. It's a two click activity which i would love to be able to set in the preference as default.

1. What's the difference between private mode in Safari which i have to turn on every time again when opening safari.
It's a two click activity which i would love to be able to set in the preference as default. It's tyering when have to do it everyday a few times. (Yes, i'm one of many who have the "i like safari but since the update crash everyday a few times" syndrome...
Yes, i have updated my system.
Yes, i have repared disk permissions with disk utility.
Am open for any other help in both cases. Thank you upfront
2. and the "tell websites not to track me" under Safari - Preference - Privacy.

That box should prevent websites using trackers to log your movements on the Web to benefit advertisers. I have no idea if it does.
Safari can keep your browsing history private. When you turn on private browsing, Safari doesn’t remember the pages you visit, your search history, or your AutoFill information, so your partner cannot see where you have been, but you must also remember to also turn off acceptance of cookies.
In all other respects Private Browsing is not as private as you might think:
http://www.switchingtomac.com/tutorials/how-to-make-safaris-private-browsing-fea ture-actually-private/
http://www.insanely-great.com/news.php?id=9054
and then Apple's own advice from here: http://www.apple.com/pro/tips/privacy_safari.html
"Note that the Private Browsing option does not prevent Safari from collecting cookies (the preference files automatically generated by many websites). The Reset Safari option clears all cookies. If you want to delete only certain ones, choose Preferences from the Safari menu, click the Security tab, and then click Show Cookies. You can select and delete individual cookies from the list that appears. Careful, though — if you’re a frequent web user, this list can be very, very long."
which is itself incomplete, the relevant part being 'If you want to delete only certain ones.
To that end it is useful to have Safari Cookies installed, which is the only cookie manager available for Safari:
http://sweetpproductions.com/safaricookies/
which automatically deletes all cookies not marked as 'favourites' when closing Safari. It does the same for Flash Cookies, but they are subject for themselves:
From this website:
http://machacks.tv/2009/01/27/flushapp-flash-cookie-removal-tool-for-os-x/
For those who do not know about Flash cookies, more properly referred to as Local Shared Objects (LSO), they operate in a similar way to regular browser cookies but are stored outside the purview of your browser, meaning you cannot delete them from within your browser, whether Safari, Firefox, Opera or any other. Typically they are issued from sites or 3rd party sites that contain Adobe Flash content. Since virtually all internet advertising is delivered in Flash, Google/Doudleclick and all other internet advertising companies are sure to be tracking your browsing behavior with Flash cookies. These companies can see you traverse the Internet as you come upon the plethora of sites that contain their embedded advertising. Check out the Wikipedia entry here.
In Mac OS X they are stored in the following location:
/User’s Home Folder/Library/Preferences/Macromedia/Flash Player/#SharedObjects
The settings for the Flash cookies are stored in:
/User’s Home Folder/Library/Preferences/Macromedia/Flash Player/macromedia.com/support/flashplayer/sys
In OS X Local Shared Objects, or Flash Cookies, are appended with a .sol suffix. Flush deletes all the Flash cookies (.sol) and their settings.
Flush can be downloaded from that page.
If you want to retain certain Flash cookies but not others, the excellent add-on for Safari called SafariCookies now includes a setting for automatically deleting flash cookies you don't want to retain, when Safari is shut down, in the same as it deals with ordinary cookies:
http://www.sweetpproductions.com/safaricookies/index.htm
which not only does that but much more equally useful stuff!
This article covers the issue in more depth:
http://www.wired.com/epicenter/2009/08/you-deleted-your-cookies-think-again/
Flash cookies are also known as 'Zombie Cookies' and are used by a number of firms, including Hulu, MTV, and Myspace. Graham Cluley, senior technology consultant at the internet security firm Sophos, told BBC News that the source of the trouble was Adobe Flash itself, which he called "one of the weirdest programs on the planet".
"I think it's highly unlikely that these large companies have abused Flash cookies - which are different from browser cookies - with malicious intent," he said.
"I think it's much more likely that the vast majority of users are simply oblivious to the bizarre way in which Adobe allows them to configure the software."

Ghostery tracks the trackers and gives you a roll-call of the ad networks, behavioral data providers, web publishers, and other companies interested in your activity.

While defining a columnar table, what is the purpose of column store type

Hi folks
I have two questions related to columnar table definition.
1. What is the purpose of column store type.
While defining a columnar table, what is the purpose of column store type (STRING ,CS_FIXEDSTRING,CS_INT etc) , when I define a table using the UI I see that the column is showing STRING but when I goto EXPORT SQL it does not show. Is this mandatory or optional ?
2.VARCHAR Vs. CHAR - In the UI when I create the table I do not see the CHAR option , but I do see lot of discussion where people are using CHAR for defining the columnar table. Not sure why UI dropdown does not show it. I also read that we should avoid using VARCHAR as those columns are not compressed, is that true, I thought the column store gives compression for all the columns. Are there certain columns which cannot be compressed .
Please let me know where I can find more information about these two questions.
Poonam

Hi Poonam
the CS_-data types are the data types that are used internally in the column store. They can be supplied but it is not at all required or recommended to do so.
SAP HANA will automatically use the correct CS_-data type for every SQL data type in your table definitions.
To be very clear about this: don't use the CS_-data types directly. Just stick to the SQL data types.
Concerning VARCHAR vs CHAR: fixed character data types are not supported anymore and don't show up anymore in the documentation.
I have no idea why you believe that VARCHAR columns are not compressed but this is just a myth.
create column table charcompr (fchar char(20), vchar varchar(20));
insert into charcompr (
    select lpad ('x', to_int (rand()*20), 'y'), null from objects cross join objects);
-- same data into both columns
update charcompr set vchar = fchar;
-- perform the delta merge and force a compression optimization
merge delta of charcompr;
update charcompr with parameters ('OPTIMIZE_COMPRESSION' ='FORCE');
-- check the memory requirements
select COLUMN_NAME, MEMORY_SIZE_IN_TOTAL, UNCOMPRESSED_SIZE, COUNT, DISTINCT_COUNT, COMPRESSION_TYPE
from m_cs_columns where table_name ='CHARCOMPR'
COLUMN_NAME    MEMORY_SIZE_IN_TOTAL    UNCOMPRESSED_SIZE   COUNT   DISTINCT_COUNT COMPRESSION_TYPE
FCHAR       3661                    70285738            6692569 20              RLE
VCHAR       3661                    70285738            6692569 20              RLE
We see: compression and memory requirements are the same for both fixed and variable character sizes.

What is the purpose of Destination Function on Submit Button?(Doesn't work)

Hi Gurus,
There is a property "Destination Function" on Submit buttons.
What is the purpose of this field.
I tried setting some values here expecting following behavior in order:
1. Process Form Request will get executed.
2. User will be navigated to the OAF page related to the Destination Function.
Destination Function property probably point to setInvokeFunction method of the OASubmitButtonBean.
Please advise on this.

What is the purpose of open/close connection data socket?

Hello everyone,
I am writing and reading values in OPC Server through data socket. What is the purpose of open/close connection data socket when writing /reading a value? Without the open/close connection element, it still work correctly. I am writing values in the server thru event stucture.I do not need any buffered reading or writing. What will happen if I didnt not use the open/close connection? Maybe it may cause some problems in my program which i didnt realise?
And I have attached an example of my program. Thanks

Hi YehChia,
I was talking about something like that:
1. Not good. since with every iteration the DS connection needs to be opened and closed.
2. Good. Since you open the connection only once then do the reads and close it afterwords.

IPod Touch Newbie: What is the purpose of the iTunes app on my iPod Touch?

What is the purpose of the iTunes app on my iPod Touch?
All it does is connect to the iTunes store if I'm near a WiFi connection. It appears to be useful only for impulse purchasing of media. So why is it not named "iTunes Store"? It appears to have no other function.
Also, to listen to my iTunes music on iPod Touch I have to click on the Music button...not the iTunes app. What logic is that?
Also, iTunes has synced a movie for me, but I have no clue how to view it on the iPod Touch. It doesn't appear in iTunes on the iPod Touch, and there is no "Movie" button anywhere. What am I missing? I can't find it anywhere.

For purchasing music, downloading podcasts,etc.

OIM: What is the purpose of "Update" while editing group memberships

Hi,
This is when you lookup a user's Resource Profile and go to "Edit" link. The process form shows up along with a drop down to edit the group memberships. When we select one of the choices such as "Groups" another window pops up where we could add more entires into the child form. In this form there is an "Update" column with a radio button besides a "Remove" column. What is the purpose of this "Update" column? We can add or delete child entries but what does update do? Is there a way to remove this selection altogether?
Thanks in advance

Update I can see used for a cases where you have multiple columns on a child table entry and want to change one of them. Strictly speaking, you can update a single column child table rather than delete and insert also. Access policies always do insert and delete actions, but you will want to implement an update task as well if you expect anyone to be editing child tables on resources directly.

What is the purpose of Multiproviders???

Hi Everyone,
I am currently trying to create a multiprovider.
I have read the SAP documentation but I still do not understand in what circumstances should I create a multiprovider for reporting.
Would appreciate if anyone can provide details on what is the purpose of multiproviders?
Assuming I have the following scenario, should I create a multiprovider for reporting?
Infocube A:-
Characteristic
- Employee Number
- Cal Month/Year
- Shift Type
Key Figure
- Hours
Infocube B:-
Characteristic
- Employee Number
- Cal Month/Year
Key Figure
- Amount
I need to report on both the key figures for each employee and what is the shift type of the employee for the specific cal month/year. The employee number, cal month/year and shift type will be used as selection parameters.
I am thinking of creating a multiprovider for this reporting need but I think there will be some problems.
For example:
1) If I input the employee number and shift type as selection parameters, the amount column will be empty when the report is displayed.
2) If I input on the employee nunmber, then I'll be able to see both the key figures when the report is displayed but the data are on different lines which does not make sense to users.
Emp ID   Shift Type    Cal Mth/Yr   Hours     Amount
200001   Shift         05.2006       10
200001   Not assigned 05.2006                 1000
Only if I don't show the shift type column, then the record will be display in a single line.
How can I rectify such a problem.
Please advise.
Thanks.
Shunhui.

Hi,
A MultiProvider is a type of InfoProvider that combines data from a number of InfoProviders and makes it available for reporting purposes. The MultiProvider does not itself contain any data. Its data comes entirely from the InfoProviders on which it is based. These InfoProviders are connected to one another by a union operation.
InfoProviders and MultiProviders are the objects or views that are relevant for reporting.
Multiprovider - used when we want to report on chracteristics and keyfigures that are in different data targets.

What is the purpose of the chain (lock symbol) between a solid color layer and its vector mask?

What is the purpose of the chain (lock symbol) between a solid color layer and its vector mask in the layer panel when creating shape layers with a shape tool? I'm just curious when locking or unlocking the solid color layer and its vector mask can make a difference.

I don't understand what you said and your shape layer looks different then mine using CS5.
When the chain is deselected, I can't do anything with the move tool on the shape layer. This is the only difference I can find. Making the solid color uniform or not doesn't change anything.
Your example shows that you moved the position of the solid color, how did you do that? I can create a solid color layer and change its uniform look by applying an effect like gradient but I can't move the solid color itself around. How is this possible?
