Wht is diff b/w sy-ucomm and ok code

hi,
what is diff b/w sy-ucomm and ok-code
Regards,
Rani.

Hi,
sy-ucomm is for doing the functions what the user wishes to do at that particular event. You use it in menus and other place . this mainly in using <pfstatus>
ok_code is generally used in screen as of I have used. You will define the function in the screen. and you can use it in the main program.
ok_code acts just as a temporary variable that stores the value of sy-ucomm.
When user interacts with the screen elements, the function code that you have assigned is filled in the sy-ucomm field which is turn gets reflected in OK_CODE.
In your ABAP programs, you should work with the OK_CODE field instead of SY-UCOMM. There are two reasons for this: Firstly, the ABAP program has full control over fields declared within it, and secondly, you should never change the value of an ABAP system field. However, you should also always initialize the OK_CODE field in an ABAP program for the following reason:
In the same way that the OK_CODE field in the ABAP program and the system field SY-UCOMM receive the contents of the corresponding screen fields in the PAI event, their contents are also assigned to the OK_CODE screen field and system field SYST-UCOMM in the PBO event. Therefore, you must clear the OK_CODE field in the ABAP program to ensure that the function code of a screen is not already filled in the PBO event with an unwanted value. This is particularly important when the next PAI event can be triggered with an empty function code (for example, using ENTER). Empty function codes do not affect SY-UCOMM or the OK_CODE field, and consequently, the old field contents are transported.

Diff b/n search help and match code

hi all,
can i know the differece between search help and match code object in terms of functionality?
is there possibility to provide matchcode object for select-options?if yes how can we provide?

same thread again.
hi,
Matchcodes were replaced with Search Helps starting with Release 4.0. Please use search helps to assign an input help to a field.
Existing matchcodes were automatically converted to search helps. A matchcode object is hereby converted to a collective search help with the same name. Each matchcode ID of the matchcode object is converted into an elementary search help with the same name and assigned to the collective search help created from the matchcode object.
A matchcode is a means of finding data records stored in the system. The matchcode is defined in the ABAP Dictionary in two steps:
You first define the relevant tables and fields for the search in a matchcode object. A matchcode object describes the set of all possible search paths for a search string.
You then create one or more matchcode IDs for a matchcode object. A matchcode ID describes a special search path for a search string. The matchcode ID defines the fields or field combinations to be used in the search.
Search Help
Use
With this function you can search for objects, thereby defining and linking different selection conditions for the search help.
Prerequisites
You can call this function by:
· Selecting Object ® Search... () in the main menu bar of the Integration Builder
· Placing the cursor on a software component version and selecting Search... () in the context menu (only in the Integration Repository)
In this case the software component version is defined as the search criteria.
Features
Defining the Object Type
You can select the object type in a dropdown list in field Object Type.
In the design (Integration Repository) you can
· Select an object type (for example Message Interface)
· Select a cross-object category (for example Interface Objects)
In the configuration (Integration Directory) you can select types Values Mapping Group and schema in addition to the individual object types.

Diff between at line selection and HIDE technique

hi all,
 wht is the diff between at-line-selection and HIDE technique.
 wht r code instructor
 wht is extended testing
 how can we find selected error records in session method ex:-if there r errors in 4th 9th 13th record.
tthnx in advance

HIDE
Syntax
HIDE dobj.
Effect
This statement stores - in the current list level - the content of the variable dobj together with the current list line whose line number is contained in sy-linno. The data type of the variables dobj must be flat and no field symbols can be specified that point to rows of internal tables, and no class attributes can be specified. The stored values can be read as follows:
For each user action in a displayed screen list that leads to a list result, all the row values stored using HIDE - that is, the row on which the screen cursor is positioned at the time of the event - are assigned to the respective variables.
If a list row of an arbitrary list level is read or modified using the statements READ LINE or MODIFY LINE, all the values of this row stored using HIDE are assigned to the respective variables.
Notes
The HIDE statement works independently of whether the list cursor was set. In particular, variables for empty list rows can be stored - that is, rows in which the list cursor was positioned using statements like SKIP.
The HIDE statement should be executed immediately at the statement that has set the list cursor in the row.
Outside of classes, constants and literals that cannot be read in list results and in the statement READ LINE can be specified for dobj outside of classes.
Example
Storing square numbers and cubic numbers for a list of numbers. The example shows that arbitrary variables can be stored independently of row content. In the real situation, one would more likely store only the number and execute the calculation, when required, in the the event block for AT LINE-SELECTION.
REPORT ...
DATA: square TYPE i,
 cube TYPE i.
START-OF-SELECTION.
FORMAT HOTSPOT.
DO 10 TIMES.
 square = sy-index ** 2.
 cube = sy-index ** 3.
 WRITE / sy-index.
 HIDE: square, cube.
ENDDO.
AT LINE-SELECTION.
WRITE: square, cube.
AT LINE-SELECTION
Syntax
AT LINE-SELECTION.
Effect
This statement defines an event block whose event is triggered by the ABAP runtime environment during the display of a screen list - provided the scren cursor is on a list line and you select a function using the function code PICK. Through the definition of this event block, the standard list status is automatically enhanced in such a way that the function code F2 and, with it, the double-click mouse function is linked up to the function code PICK.
Note
If the function key F2 is linked with a function code different than PICK, each double click will trigger its even, usually AT USER-COMMAND, and not AT LINE-SELECTION.
Example
This program works with the standard list status. A line selection with the left mouse key causes the event AT LINE-SELECTION and creates details lists.
REPORT demo_at_line_selection.
START-OF-SELECTION.
WRITE 'Click me!' COLOR = 5 HOTSPOT.
AT LINE-SELECTION.
WRITE: / 'You clicked list', sy-listi,
 / 'You are on list', sy-lsind.
IF sy-lsind < 20.
 SKIP.
 WRITE: 'More ...' COLOR = 5 HOTSPOT.
ENDIF.

What is diff b/w sy-index and sy-tabix

Hi all,
Can u plz give me the diff b/w sy-index and sy-tabix exactly and how it works.
Thanks & Regards
Venkat

Hi Venkat,
1.SY-INDEX
->Current loop pass
->In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
2.SY-TABIX
->Current line index
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.
I think that it clears ur doubt.
Thanks,
Venkat.O

Diff b/n sy-tabix and sy-indx

diff b/n sy-tabix and sy-indx ?

Hi Henry,
SY-INDEX is the value of the current iteration. It is applicable for the following programming constructs in ABAP -
DO...ENDDO.
WHILE...ENDWHILE.
SY-TABIX (TABle IndeX) is applicable to internal tables. If you scroll down in the link which Eddie has given, you will find a more detailed explanation for sy-tabix and which statements affect its value.

Regarding sy-ucomm and ok_code

hi experts,
gud morning,
i got something for sy-ucomm and ok_code....
answer:::
In the same way that the OK_CODE field in the ABAP program and the system field SY-UCOMM receive the contents of the corresponding screen fields in the PAI event, their contents are also assigned to the OK_CODE screen field and system field SYST-UCOMM in the PBO event. Therefore, you must clear the OK_CODE field in the ABAP program to ensure that the function code of a screen is not already filled in the PBO event with an unwanted value. This is particularly important when the next PAI event can be triggered with an empty function code (for example, using ENTERS). Empty function codes do not affect SY-UCOMM or the OK_CODE field, and consequently, the old field contents are transported.
cud u plz explain the meaning of the bold part how can we see that the contents are also copied in the pbo side as done in pai.......
null

SAP recommends that in dialog program always use OK_Code instead of sy-ucomm. Here is what the help says
In your ABAP programs, you should work with the OK_CODE field instead of SY-UCOMM.

This is a long standing issue dating back many years. The general answer is that you control the OK_CODE field while SAP controls the SY-UCOMM field. You assign field OK_CODE to the OK code field in the screen painter and SAP copies SY-UCOMM to your OK_CODE field. Now you have control over the value. If you start invoking other code, like SAP utilities that display screens, you can be guaranteed that the value in OK_CODE will still be there, while you have no idea what SAP might be doing with SY-UCOMM.
This is a design decision that was probably made about 20 years ago when screen processing was introduced. In most cases, you can probably use SY-UCOMM and not have any problems but there are probably cases out there where SAP has done something tricky and you will have a problem.
Because there are unknowns out there, I always define an OK_CODE and do not use SY-UCOMM for standard screen processing. For me this is a long standing habit.
OK_Codes are like function code for each button or for any action on the screen.
When you press SAVE or when you Press some Button on the screen, your every action is recorded by using the OK_COde.
for example for ENTER button it is '/00'.
While you record BDC's using SHDB you will come to know all these OK codes.

Diff. b/w 3.5 and 3.0b

Hi bwers,
Please let me know the diff. b/w 3.5 and 3.0b. Tell me in an explanation way rather than sending the documents. Thanks in advance.
And one more query is i have a cube consisting of a 3requests in green and 1 red request and a 3 requests green.. Is it possible to delete that red request and if so what will be the affect ..

Hi,
the main difference of 3.5 in respect to 3.0b is the broadcasting and some other front-end functions... The datawarehousing workbench is the same.
Business content is also enhanced in 3.5....
SEM-BPS also enhanced...
Yes you can delete that red request and you will then miss this data. Check if this request needs to posted in the cube. If yes then analyze why it failed. Take the corrective measures and try to repost it.
If you don't need it then just delete it.
hope this helps,
Olivier.

Diff B/W master data and transaction data

Hi all,
What is the main Diff B/W master data and transaction data. give me some example ?
Thanks in Advance
Krish...

hi krish,
MASTER Data is the data that exists in the organization like employee details, material master, customer master, vendor master etc. These are generally created once.
Master data are distributed throughout the company, they are often not standardised and often redundant. As a result it is very costly to offer efficient customer service, keep track of supply chains and make strategic decisions. With SAP Master Data Management (SAP MDM) these important business data from across the company can be brought together, harmonised and made accessible to all staff and business partners. As a key component of SAP NetWeaver, SAP MDM ensures data integrity via all IT systems.
Regardless of the industry, companies often work with different ERP and Legacy systems. The result: the business processes are based on information about customers, partners and products which is displayed in different ways in the systems. If the data are recorded manually, there are more inconsistencies: some data sets are entered several times, others cannot be retrieved by all divisions of the company.
As corporate applications are becoming increasingly complex and produce ever greater amounts of data, the problem is intensified further. Nevertheless, your employees must work with the inconsistent data and make decisions on this basis. The lack of standardised master data easily leads to wrong decisions, which restrict efficiency and threaten customer satisfaction and profitability.
In a word: in order to save costs and ensure your companys success it is necessary to consolidate master data about customers, partners and products, make them available to all employees beyond system boundaries and use attributes valid company-wide for the purpose of description.
TRASNACTION Data - These are the business documents that you create using the master data - Purchase orders, sales orders etc

Diff b/w occurs 0 and occurs1?

Hi
what is the main diff b/w occurs 0 and occurs1?
thanks and regards,
sap abap.

OCCURS 0 creates an internal table with no rows pre-buit in it upon creation.
OCCURS 1 creates an internal table with 1 row pre-built in it upon creation.
The changing of OCCURS upon creation is really only benenficial when you KNOW ahead of time that a certain number (or large number) of rows WILL NEED to be created on-the-fly. In these cases, you will get better run-time execution by having an OCCURS 10000, for example.IF you know that at least 10,000 rows will be needed, this will help your prog to run faster as it does not need to expand the table EACH time (or at least until it reaches beyond 10K).
Creating the additional rows during r/t is expensive, if you can have the foresight to know in advance for large progs, you can help the run-time engine.
Don't forget points for helpful answers.

Diff b/w reference type and elementary type

hi all
can any one what is the diff b/w reference type and elementary type in data element ....
thanks
lokesh

The data type attributes of a data element can be defined by:
Specifying a domain whose attributes are copied by the data element.
Specifying a build-in type where the data type, number of places, and possibly decimal places can be directly specified.
Specifying a reference type, i.e. reference to a class, an interface, a type defined in the Dictionary, a built-in type, or a generic reference to ANY or DATA.
In the maintenance screen you can set the option you require by setting the appropriate flag (domain, built-in type, reference type) and filling in the corresponding input fields.
A reference type is a reference to another type. There are the following kinds of reference types:
Reference to a class or an interface
Reference to a type defined in the Dictionary
Generic reference to ANY, OBJECT, or DATA
Reference to a built-in Dictionary type with specification of the length and possibly also the decimal places
You can use a reference type to define the data type properties for a data element, or for typing the component of a structure or the line type of a table type.
In the field Referenced type, enter the name of a class, an interface, the generic references DATA, OBJECT, ANY, or the name of a type defined in the Dictionary. If the reference type is to be a predefined Dictionary type, choose the reference to the predefined type. Enter the number of characters and, if required, the number of decimal places.
where as
The data class describes the data format at the user interface.
If a table field or structure field or a data element is used in an ABAP program, the data class is converted to a format used by the ABAP processor. When a table is created in the database, the data class of a table field is converted to a corresponding data format of the database system used.
You can find a detailed description of the data classes allowed in the ABAP Dictionary in Overview of the Data Classes.

Diff b/w Data warehouse and Business Warehouse

Hi all,
what is the Diff b/w Data warehouse and Business Warehouse?

hi..
The diferrence between Datawarehousing and Business Warehouse are as follows.
DataWarehousing is the concept and BIW is a tool that uses this concept in Business applicaitons.
DataWarehousing allows you to analyze tons of data (millions and millions of records of data) in a convinent and optimum way, it is called BIW when applied to Business applications like analyzing the sales of a company.
Advantages- Consedering the volume of business data, BIW allows you to make decisions faster, I mean you can analyze data faster. Support for multiple languges easy to use and so on.
