What is the use of 'keep' parameter in BDC

Hi
In BDC while transfering data, what is the use of 'keep' parameter in BDC.

Hi Jyothsna,
In the function module BDC_OPEN_GROUP, the EXPORTING parameter KEEP acts as a deletion indicator for session in which the batch data executed.
CALL FUNCTION 'BDC_OPEN_GROUP'
EXPORTING
CLIENT = SY-MANDT
DEST = FILLER8
GROUP = FILLER12
HOLDDATE = FILLER8
 KEEP = FILLER1
---
KEEP retains the session after successful processing if its value is set to 'X'. A session that is kept remains in the input/output queue until an administrator deletes it in SM35 transaction.
Sessions that contain errors in transactions are kept even if KEEP is not set.
Default: If not set, then sessions that are successfully processed are deleted. Only the batch input log is kept in SM35 transaction.
Hope this sort out your query.
PS If the answer solves your query, plz close the thread by rewarding points to each reply.
Regards

What is the use of table control in bdc is it same in module pool table con

Hi,
What is the use of table control in bdc is it same in module pool table control?
regards
eswar

Hi,
Table control means it contains as table and it will scroll in vertical and horizontal.
In module pool by using screen we can create new table control.
But BDC table control means here we can populate the data into the table control.
i.e.if you take VA01 for sales order creation in the belwo of VA01 screen there is table control for the filling of material details so here we will write the code to populate the data into the table control screen.
Thanks and regards,

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.

What is the use of COL_SELECT_MASK IN fm gui_download?

Hi i Just want to know what is the use of col_select_mask in GUI_DOWNLOAD.
currently i need to work on one report where they are passing this parameter to gui_download.
result is it is taking only 255 char column length in the downloaded excel...
i need to add extra fields to the downloaded excel..but it is taking only 255 how to over come this issue?
i tried commented the COL_SELECT_MASK but it is taking unnecessary fields in the internal table i dont know how come they are excluding some fields without downloading ?Any one any idea?
Regards
sas .

Well thanks for the information.
Now i understood that
in itab there are 10 fields where user wants to see in the excel only 8 fields.
so they use col_mask parameter what ever columns we pass only those o/p we can see in the output.
so now that col_mask need to increase to few more fields in result which the size of excel is more than 255 char which in result need to display 8 + my 6 fileds = 14 fields.
due to over size it is displaying only 10 fields. Rest 4 are missing.
so using COL_MASK is there any way to define more than 255 char column length?
Regards
sas....
DiD you check the FM where it is written as if col_sel = 'X'.
COL_SLE_MASK = 'xxx'.
then it will download 1 , 3 5 columns???/
what is this i dont understand???

sas

What is the use of Generic class in java

hi everyone,
i want to know that
what is the use of Generic class in java ?
regards,
dhruvang

Simplistically...
A method is a block of code that makes some Objects in the block of code abstract (those abstract Objects are the parameters of the method). This allows us to reuse the method passing in different Objects (arguments) each time.
In a similar way, Generics allows us to take a Class and make some of the types in the class abstract. (These types are the type parameters of the class). This allows us to reuse the class, passing in different types each time we use it.
We write type parameters (when we declare) and type arguments (when we use) inside < >.
For example the List class has a Type Parameter which makes the type of the things in the list become abstract.
A List<String> is a list of Strings, it has a method "void add(String)" and a method "String get(int)".
A List<File> is a list of Files, it has a method "void add(File)" and a method "File get(int)".
List is just one class (interface actually but don't worry about that), but we can specify different type arguments which means the methods use this abstract type rather than a fixed concrete type in their declarations.
Why?
You spend a little more effort describing your types (List<String> instead of just List), and as a benefit, you, and anyone else who reads your code, and the compiler (which also reads your code) know more accurately the types of things. Because more detail is known, the compiler is able to tell you when you screw up (as opposed to finding out at runtime). And people understand your code better.
Once you get used to them, its a bit like the difference between black and white TV, and colour TV. When you see code that doesn't specify the type parameters, you just get the feeling that you are missing out on something. When I see an API with List as a return type or argument type, I think "List of what?". When I see List<String>, I know much more about that parameter or return type.

What is the use of at-exit in mudule pool

hi
what is the use of at-exit in mudule pool. what is the use when we keep the function type as 'E' for a function code

AT EXIT-COMMAND lets you call a module before the system executes the automatic fields checks.
Automatic field checks can be avoided through AT EXIT-COMMAND, which works exactly the same way as CANCEL works from standard tool bar. In the R/3 screen, if your want to quit the processing of that particular screen without entering the mandatory fields then user can click the CANCEL button, same functionality can be incorporated in the user defined transaction by usine AT EXIT-COMMAND. This module can be called before the system executes the automatic field checks.
Code for AT EXIT-COMMAND in flow logic and in module pool program can be written as follows.
In Flow Logic:
PROCESS AFTER INPUT.
MODULE EXIT AT EXIT-COMAND.
In Module Pool Program:
MODULE EXIT.
case okcode.
when 'EXIT'.
leave to screen 0.
ENDMODULE.
To achieve this kind of functinality, the pushbutton or menu item should be assigned a function type 'E' (Exit). It tells the system to process this particular module before carrying out any field checks.
Rewards if useful.

What is the use of CTU_PRAMS in bdc programming?

what is the use of CTU_PRAMS in bdc programming?
can any explain wit a sample code.

Hi,
Hi,
If u write table control bdc program in 14'' monitor screen, then if the same program u run at different monitor size, then the screen resolution problem comes in to the picture,
like, u get 5 records in table control in one screen, and some other records in other screen, to avoid this screen resolution problem we use CTU-PARAMS Structure.
In ur program u have to set
defsize type ctu_params-defsize value 'X',
Then u will be free of screen resolution problem.
Fill the str CTU_PARAMS-defsize = 'X' and pass in CTU stmnt as
call transaction 'XXX' options using t_bdcdata ctu_params.
Analysing :
1. If nothing works, then we have to
some ifs & buts.
2. There shall be normally
2-4 different kinds of resolution
on various users comptuers.
3. Based on this,
we have to know beforehand,
what will be the number of rows
in the table control.
4. The user can be given
a selection/paraemter
for resolution
eg. 800x600
1024x100
axb
etc.
5. Based on this, we will hardcode
in the program (based upon our knowledge/recording
which we have seen and done)
we will hardcode
the number of lines
in the VARIBLE.
6. Then we can simply use this variable
for our LOOP and logic purpose.
7. It will be the responsibiltiy of the
use to CHOOSE THE CORRECT resolution,
on the selection-screen.
For screen resolution use ctu_params, with default size
Data : f_option type ctu_params,
f_option-updmode = 'S'.
f_option-defsize = 'X'.
f_option-dismode = 'N'.
call transaction 'VA01' using bdcdata options from f_option messages into bdcerror.
CALL TRANSACTION tcode... OPTIONS FROM opt
... OPTIONS FROM opt
Effect
Allows you to control processing using the values of the componetns of the structure opt, which must have the ABAP Dictionary type CTU_PARAMS. The components have the following meanings:
DISMODE
Display mode (like the MODE addition)
UPDMODE
Update mode (like the UPDATE addition)
CATTMODE
CATT mode (controls a CATT)
CATT mode can have the following values:
' ' No CATT active
'N' CATT without single-screen control
'A' CATT with single-screen control
DEFSIZE
Use default window size
RACOMMIT
Do not end transaction at COMMIT WORK
NOBINPT
No batch input mode (that is, SY-BINPT = SPACE)
NOBIEND
No batch input mode after the end of BDC data.
The components DEFSIZE , RACOMMIT, NOBINPT, and NOBIEND always take the following values:
'X' Yes
' ' No
If you do not use the OPTIONS FROM addition, the following control parameter settings apply:
DISMODE
From addition MODE
UPDMODE
From addition UPDATE
CATTMODE
No CATT active
DEFSIZE
Do not use default window size
RACOMMIT
Successful end on COMMIT WORK
NOBINPT
Batch input mode active ( SY-BINPT = X
NOBIEND
Batch input mode remains active after the BDC data

What is the use of t-rfc in ALE? compared to t-rfc, Qrfc is better and effi

what is the use of t-rfc in ALE? compared to t-rfc, Qrfc is better and efficient?

Hi Sunil,
These are the types of RFC
Asynchronous RFC (aRFC)
Synchronous RFC (sRFC)
Transactional RFC (tRFC)
Queued RFC (qRFC)
Parallel RFC (pRFC)
Asynchronous RFC :
This is used when you need to increase the performance of ABAP program by having system call more than one function module in parallel than forcing the program to wait for results .
Transactional RFC
This let you group one or more function module call together o tRFC LUW and ensure that fucnction module within LUW is called once . In contrast to aRFC and sRFC the tRFC belonging to tRFC LUW are executed in order .
tRFC is always used if a function is executed as a Logical Unit of Work (LUW). Within a LUW, all calls are
1.Executed in the order in which they are called
2.Executed in the same program context in the target system
3.Run as a single transaction: they are either committed or rolled back as a unit.
Implementation of tRFC is recommended if you want to guarantee that the transactional order of the calls is preserved
Asynchronous remote function calls (aRFCs) are similar to transactional RFCs, in that the user does not have to wait for their completion before continuing the calling dialog. There are three characteristics, however, that distinguish asynchronous RFCs from transactional RFCs:
When the caller starts an asynchronous RFC, the called server must be available to accept the request.
The parameters of asynchronous RFCs are not logged to the database, but sent directly to the server.
Asynchronous RFCs allow the user to carry on an interactive dialog with the remote system.
The calling program can receive results from the asynchronous RFC.
You can use asynchronous remote function calls whenever you need to establish communication with a remote system, but do not want to wait for the functions result before continuing processing. Asynchronous RFCs can also be sent to the same system. In this case, the system opens a new session (or window). You can then switch back and for between the calling dialog and the called session
RECEIVE RESULTS FROM FUNCTION Remotefunction is used within a FORM routine to receive the results of an asynchronous remote function call. The following receiving parameters are available:
IMPORTING
TABLES
EXCEPTIONS
The addition KEEPING TASK prevents an asynchronous connection from being closed after receiving the results of the processing. The relevant remote context (roll area) is kept for re-use until the caller terminates the connection.
Hope this resolves your query.
Reward all the helpful answers.

What is the use of variant in the alv report

hello all,
what is the use of variant in the alv report

Hi,
For Variants
follow the link:
http://help.sap.com/search/highlightContent.jsp
Variants allow you to save sets of input values for programs that you often start with the same selections. You can use them for any programs except subroutine pools (type S).

Running a Program with a Variant
Variants: Overview
Use
Whenever you start a program in which selection screens are defined, the system displays a set of input fields for database-specific and program-specific selections. To select a certain set of data, you enter an appropriate range of values.
For further information about selection screens, see Working with selection screens in the ABAP User's Guide.
If you often run the same program with the same set of selections (for example, to create a monthly statistical report), you can save the values in a selection set called a variant.
You can create any number of variants for any program in which selection screens are defined. Variants are assigned exclusively to the program for which they were created.
You can also use variants to change the appearance of the selection screen by hiding selection criteria. This is particularly useful when you are working with large selection screens on which not all of the fields are relevant.
Reports, module pools, and function groups may have several selection screens. It is therefore possible to create a variant for more than one selection screen.
Variants are an interface between the user and the selection screen. They can be used both in dialog and in background mode, although their uses are slightly different.
Variants in Dialog Mode
In dialog mode, variants make things easier for the user, since they save him or her from continually having to enter identical values. They can also make the selection screen easier to read, because you can use them to hide input fields. Running an executable program with a variant containing an optimal set of values also reduces the capacity for user error. The optimized database selections speed up the runtime of the program.
Variants in Background Mode
Variants are the only method for passing values to a report program in a background job. Therefore, when you run a program in the background, you must use a variant (or SUBMIT... VIA JOB). To avoid you having to create a new variant each time you run the report, ABAP contains a mechanism allowing you to pass variable values to variants. See variable values in variants.
To ensure that an executable program is always started using a variant, you can specify in the program attributes that the program may only be started in this way.
Features
Creation of variants
Display, change, copy, print, and delete variants
Use and definition of variables in variants
Variable date calculation
User-specific fixed values
Fixed values in table TVARV
You access the variant maintenance tool from the initial screen of the ABAP Editor. Enter the name of the program, select Variants in the Sub-objects group box, and then choose Display or Change.
Functions
The above screen allows you to:
Create variants
Display the variant directory
Display and change values and attributes
Copy, delete, and rename variants
Before creating a new variant for a program, you should check whether you can use or adapt an existing variant instead.
There are two ways to display variants:
Position the cursor on the Variant field on the initial screen and press F4. The following dialog box lists all of the available variants:
Choose Variants ® Directory on the initial screen:
Creating Variants
Prerequisites
You must have defined one or more selection screens for the relevant program. The program may have any type except type S.
Procedure
On the initial screen of the ABAP Editor, enter the name of the program for which you want to create a variant, select Variants in the Sub-objects group box, and choose Change.
On the variant maintenance initial screen, enter the name of the variant you want to create.
Note the naming convention for variants (see below).
Choose Create.
If the program has more than one selection screen, a dialog box appears in which you can assign the variant to one or more screens. The dialog box does not appear if the program only has one selection screen. In this case, the selection screen of the program appears straight away.
If there is more than one selection screen, select the screens for which you want to create the variant.
Example:
If you choose Variant for all selection screens, the variant also applies to any selection screens that you create after creating the variant.
Otherwise, the variant only supplies values to the selection screens that you select in the list.
Choose Continue.
The (first) selection screen of the program appears.
If your program has more than one selection screen, use the scroll buttons in the left-hand corner of the application toolbar to navigate between them. If you keep scrolling forwards, the Continue button appears on the last selection screen.
Enter the required selections, including multiple and dynamic selections.
Choose Continue.
Result
When you have finished, an overview screen appears (ABAP: Save Attributes of Variant), on which you can enter the attributes of your variant and save it.
Note that when you create a new variant, you must enter both values and attributes.
Names of variants: Names can consist of up to 14 alphanumeric characters. The "% " character is not allowed. If you want the variant to be transported automatically with its program, you must create a system variant. The name of a system variant starts "CUS&" for customers, and "SAP&" for SAP system variants. You can only use the "&" character within this prefix in the name of a system variant. It may not occur in any other context. System variants are administered by the Workbench Organizer. Although you can create and access variants from any client, they are always stored in client "000".

What is the use of version in workflow

what is the use of versioning in workflow. how can i use it in real time senarios.

Hi,
Its the same way as in reports and other areas. You can generate a current version and keep making changes to the latest version so that you can always revert back to the older one in case of problems.
It is also used when you transport the workflow from one system to other. Assume you have already transported a workflow definition to the production system. Now this workflow also has been instantiated and some instances are running in production. Now if you make some modifications in this workflow and transport (even with the same version number) it will get transported to the production under a new available version number. The previous instances of the workflow (in production) will continue to run referring to the older version available and any new instances will continue with the latest transported workflow definition.
Thanks,

What is the use of passing object reference to itself ?

What is the use of passing object reference to itself ?
regards,
namanc

There is an use for returning an object reference from itself, for instance:
class C {
public:
     C append(C c) {
         // do something interesting here, and then:
         return this;
}You can "chain" calls, like this:
C c = new C();
C d = new C();
C e = new C();
c.append (d).append (e);Maybe the OP has "inverted" the common usage, or thought about a static method of a class C that requires a parameter of type C (effectively being a sort of "non-static method").
class C {
    static void doAnotherThing (C c) {
        c.doSomething(); //-- effectively C.doAnotherThing(c) is an "alternative syntax" for c.doSomething()

What is the use of NoAccess in reports

Hi Gurus
1. what is the use of NoAccess Role in Financial reports?
regards
Sarilla

I have never really used it, but I guess it could be used in a case like this: You disable the reports for a period of time and want to keep the users in the access list, so when you enable the reports again, you could basically just edit their access instead of starting from scratch.
Or here is another one. You give access to a group, but want to exclude a user, who belongs to this group from viewing the report.
