Hi,
see this prog..
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>
USER COMMAND will perform actions on radiobutton click, or wen puhbutton is cliketced
in this if the user clicks a push button, see bold letters..in the prog

SET parameter :
this is used to pass a value from one report a memory n from there we can use in the same report or the other report..
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
Hope this helps u,

How to pass value to select-option parameter using SET PARAMETER Command

Hi,
Am passing values to selection-screen fields in report RV13A004 ( used in VK11, VK12 and VK13). using below statement but material number is select-option in this report. am able to pass MATERIAL FROM using SET PARAMETER ID, can i know how to pass values MATERIAL TO range in select-options fields using SET PARAMETER Command ??
Passing values to parameter id
set parameter id 'VKS' field kschl.
set parameter id 'VKO' field vkorg.
set parameter id 'VTW' field vtweg.
set parameter id 'KDA' field erdat.
set parameter id 'MAT' field matnr_from.
Change condition price.
call transaction 'VK12' and skip first screen.
Thanks in advance.
Regards,
Balamurugan.

Hi,
instead of using set parameters and dden call transaction use this..........
submit RV13A004 WITH SELECTION-TABLE rspar
Effect
If you specify this addition, parameters and selection criteria on the selection screen are supplied from an internal table rspar. You must specify an internal table with the row type RSPARAMS for rspar. The structured data type RSPARAMS is defined in the ABAP Dictionary and has the following components, all of which are data type CHAR:
SELNAME (length 8),
KIND (length 1),
SIGN (length 1),
OPTION (length 2),
LOW (length 45),
HIGH (length 45).
To supply parameters and selection criteria for the selection screen with specific values, the lines in the internal table rspar must contain the following values:
SELNAME must contain the name of a parameter or selection criterion for the selection screen in block capitals
KIND must contain the type of selection screen component (P for parameters, S for selection criteria)
SIGN, OPTION, LOW, and HIGH must contain the values specified for the selection table columns that have the same names as the selection criteria; in the case of parameters, the value must be specified in LOW and all other components are ignored.
If the name of a selection criterion is repeated in rspar, this defines a selection table containing several lines and passes it on to the selection criterion. If parameter names occur several times, the last value is passed on to the parameter.
The contents of the parameters or selection tables for the current program can be entered in the table by the function module RS_REFRESH_FROM_SELECTOPTIONS.
Notes
In contrast to selection tables, the data types of the components LOW and HIGH in table rspar are always of type CHAR and are converted to the type of the parameter or selection criterion during transfer, if necessary.
When entering values, you must ensure that these are entered in the internal format of the ABAP values, and not in the output format of the screen display.
Cheers
Will.

Set PF Status and At-Line Selection & At User-Command

Hi All
I've used set PF status, at user command and at-line selection in my program. initially when i click on the material number it was not drilling further that is it was not taking to secondary list. i commented the PF status and tried. then it was working fine. Later, after checking on couple of doc i added F.code PICK in my PF status and uncommented the set-PF status in my program it was working fine. Now my question is why this kind of behaviour. When i uncomment the PF status and run the program without the f.code PICK in my PF status(se41) it was not working but after inlcuding the F.code in my PF it is working. Any good explanation?
thks

hi,
generally fuction code is useful for the system to find on which button or in which area the user has clicked in. based on the function code the system executes the satatements that are in user command. in your case i think u didnt gave any functionality in user-command. when at-user command is a event in interactive reporting which is triggered based on the button u had clicked.
at line-selection event uses two system variables
   1. sy-lsind [ current list index number ]
   2. sy-lisel [ contains the current area in which user ckicked ].
   3. sy-ucomm [ function code of clicked button ].
using these 3 vars we can drill down to 21 lists [ including 1st list ]
if helpful reward some points.
with regards,
suresh.

How to set parameter in rtf template

Hi,
I've created a data model query using a parameter in BI Publisher Enterprise. When I'm showing the data I'm first ask for the parameter value.
Now I want to create a rtf template in BI Publisher Desktop. What do I have to do that the user can set the parameter and then see the result? So how to set the parameter in my query?
Thanks
chrissy

Hey Chrissy... i am realy sorry, i have guided u in the wrong way...
Above which i have explained was about Variable....
To test passing a parameter value, ff you are using the:
XML Publisher Runner – on the Setting tab enter a new line containing:
Name: xslt. InvThresh
Value: 1000
Template Builder
In the config file under <<TEMPLATE_BUILDER_HOME>>/config enter under the Properties section:
<property name="xslt.InvThresh">1000</property>
<xsl:param name="InvThresh" select="0" xdofo:ctx="begin"/>
InvoiceNumber Inovice Amount
Grp: Invoice13222-2 $100.00EFE
Grp: Invoice= <?for-each:G_INVOICE_NUM?><?if:ACCTD_AMT>$InvThresh?>
13222-2 = <?INVOICE_NUM?>
$100.00= <?ACCTD_AMT?>
EFE = <?end if?><?end for-each?>
Hope this will help u out....
sorry for tht .....
Thanks

User command is not getting triggered in interactive ALV with LIST display

Hi experts,
I have developed an interactive ALV report with LIST display. Here, the issue is, when i double click a record in the primary ALV list, the control must go to the USER COMMAND event which i have written in my report. But the user command event is not getting triggered at all when i double click any record.
It gives the following information instead.
"Choose a valid function".
(My user command name and its respective form name are same.)

the SET PARAMETER ID 'FBAS' i m using is right? if not plz suggest me how to find out correct one?

Hi Vicky,
To know the Parameter Id of any field in a transaction ,
you just press F1 onthe particular field then in technical settings under Field data
you can see the PARMATER ID.
So if you check like this you can see 'BLN' as parameter id for Document number in FB03
transaction

I have a problem with ALV Grid User Command?

Hi Experts,
I have a problem with ALV GRID User Command.
I am calling TCODE IW33 (Order Display) from the ALV output at first time by selecting an order. But, User command is calling IW33 Initial screen with blank value of order. Even I checked in debugging the value what I selected is passing properly, but once that screen (IW33 Initial) displays, value doesn't appear. Then, Manually, I created another session and gone to TCODE IW33 and displayed an order. After that I came out from that order. Then again run my ALV program and selected another order, now order is displaying, but not what I selected current order instead of displaying previous order what I just displayed manually. If I selected any other order, system will display the same order what I dislayed manually.
Here is my code.
FORM user_command_alv USING u_ucomm TYPE sy-ucomm
                       us_self_field TYPE slis_selfield.
CASE u_ucomm.
WHEN '&IC1'.
READ TABLE it_final INDEX us_self_field-tabindex INTO wa_final.
        WHEN 'ORDER'.
          IF NOT wa_final-order IS INITIAL.
            SET PARAMETER ID 'COK' FIELD wa_final-order.
            CALL TRANSACTION 'IW33' AND SKIP FIRST SCREEN.
          ENDIF.
endform.
PARAMETER ID 'COK' also the standard one.
Could you please help me out, Where I did wrong?
If I select any order, that order only should display.
Thanks in advance.
Regards,
Sarayu.

hi,
Please check it once the Paramater ID is 'ANR' for IW33 order number.
Hope this may help.

WLC 4400 issue on "user login policies" parameter.

Hi,
I'm using a Cisco Wireless controller in my company.
(the model is a AIR-WLC4402-50-K9 in 4.2.207.0 version).
The WLAN is configured with WPAv2 AES and 802.1X (PEAP MS-CHAPv2) authentication on an external Microsoft IAS server (2003 R2).
the authentication rely on Active Directory login and password.
The user authentication works fine and the WLAN too.
But it's possible for a single user to log on different laptops with the same AD login and password and use the wireless network.
And it has to be forbiden by "user login policies" parameter set to 1 on the WLC (in security parameters).
Does anybody says if it's a known issue and how to solve this problem?
thanks,
raphael Paviot.

Dancampb,
Many thanks , you're right, I have to find the solution on IAS server side.
In fact, I have also applied these commands on the controller and the max-user login works (in the case of an externan radius server).
I have seen it in the "message logs".
(Cisco Controller) config>advanced eap max-login-ignore-identity-response disable
(Cisco Controller) config> netuser maxuserLogin 1
But the problem still remain , because the IAS server is not case sensitive for user logins instead of the Wireless Controller.
For exemple:
raphaelpaviot login and RaphaelPAVIOT login are:
-one user for the IAS server.
-two different users on the WLC.
cordially.

Pf status and user-command

hi
can any one explain me about pf-status and user-command? what is the difference between this two and how to display icons in it.
max reward points for good answer
thanks
alka

Hi alka ritu ,
Check the following websites for good documentation o n pf status and user-command
http://help.sap.com/saphelp_nw04/helpdata/en/9f/dba34635c111d1829f0000e829fbfe/content.htm
http://help.sap.com/saphelp_nw04/helpdata/en/9f/dba99935c111d1829f0000e829fbfe/content.htm
1. How to set pf-status
set pf-status ZZBILSTA.
2. How to set pf-status excluding/including single menu items
You can exclude menus by using exclude :
set pf-status ZZBILSTA excluding PST.
Note: Can also be used with include instead of exclude
3. How to set pf-status excluding/including several menu items
You have to use an internal table to store the status you want to ex- or include:
DATA:BEGIN OF I_PF_STATUS_TAB OCCURS 10,
FCODE,
END OF I_PF_STATUS_TAB.
FORM SET_PF_STATUS_POSTER.
REFRESH I_PF_STATUS_TAB. MOVE PST TO I_PF_STATUS_TAB. APPEND I_PF_STATUS_TAB. MOVE ART TO I_PF_STATUS_TAB. APPEND I_PF_STATUS_TAB. SET PF-STATUS ZZBILSTA EXCLUDING I_PF_STATUS_TAB.
ENDFORM.
4. Setting PF status to the (SAP) system default
set pf-status BASIC.
5. How to check for pf-status
AT USER-COMMAND.
CASE SY-UCOMM. WHEN ART. PERFORM STYR_ARTSKONTI. WHEN PST. PERFORM STYR_POSTER. WHEN BIL. PERFORM VIS_BILAG. ENDCASE.
6. Use of SY-PFKEY
You can use the system variable sy-pfkey to retrieve the name of the current pf status
USER-COMMAND:
If the user chooses a function code during list processing that is neither processed by the system, or PICK or PFnn, the system triggers the event AT USER-COMMAND. For this event, you must define your own GUI status for a list. To react to your own function codes in a program, you must define the following event block:
AT USER-COMMAND.
statements.
In this event block, you can use an IF or CASE structure to differentiate between the function codes. They are available in the system field sy-ucomm. There are further system fields that are filled in list events, such as sy-lsind and sy-pfkey, that allow you to make further case distinctions.
Triggering a List Event from the Program
You can trigger a list event from the program as follows:
SET USER-COMMAND fc.
This statement takes effect after the current list is completed. Before the list is displayed, the event assigned to function code fc is triggered, regardless of the dialog status you are using.
The effect is the same as when the user chooses the function. In other words, predefined list function codes are trapped and processed by the runtime environment, the function codes PICK and PFnn trigger the AT LINE-SELECTION and AT PFnnevents, and user-defined function codes trigger the AT USER-COMMAND event block.
Function code PICK triggers an event only if the cursor is located on a list line.
Using this statement in conjunction with the function codes reserved for system functions, you can call the system functions from the program. For example, you can use SET USER-COMMAND '%SC' to call the Find dialog box directly, or to position the list correctly before it is displayed.
If you use several SET USER-COMMAND statements while creating a list, the system executes only the last one.

AT USER COMMAND event in interactive reports

hi experts,
Can anyone explain me about AT USER COMMAND event with one practical ex.
thanks in advance
R.vijai

Hi vijaya kumar,
 If the user chooses a function code during list processing that is neither processed by the system, or PICK or PF<nn>, the system triggers the event AT USER-COMMAND. For this event, you must define your own GUI status for a list. To react to your own function codes in a program, you must define the following event block:
AT USER-COMMAND.
<statements>.
In this event block, you can use an IF or CASE structure to tell the function codes apart. They are available in the system field SY-UCOMM. There are further system fields that are filled in list events, such as SY-LSIND and SY-PFKEY, that allow you to make further case distinctions.
REPORT Test_program.
START-OF-SELECTION.
SET PF-STATUS 'TEST'.
WRITE: 'Basic list, SY-LSIND =', sy-lsind.
AT LINE-SELECTION.
WRITE: 'LINE-SELECTION, SY-LSIND =', sy-lsind.
AT USER-COMMAND.
CASE sy-ucomm.
 WHEN 'TEST'.
 WRITE: 'TEST, SY-LSIND =', sy-lsind.
ENDCASE.
With this code double click on 'TEST' and define your own PF status and give user command as TEST and check out this useful programe.
All the very best to you.

At user command in alv's

how to handle at user commads in alv's?

Hi Praveen
Interactive Reports
As the name suggests, the user can Interact with the report. We can have a drill down into the report data. For example, Column one of the report displays the material numbers, and the user feels that he needs some more specific data about the vendor for that material, he can HIDE that data under those material numbers.
And when the user clicks the material number, another report (actually sub report/secondary list) which displays the vendor details will be displayed.
We can have a basic list (number starts from 0) and 20 secondary lists (1 to 21).
Events associated with Interactive Reports are:
AT LINE-SELECTION
AT USER-COMMAND
AT PF<key>
TOP-OF-PAGE DURING LINE-SELECTION.
HIDE statement holds the data to be displayed in the secondary list.
sy-lisel : contains data of the selected line.
sy-lsind : contains the level of report (from 0 to 21)
Interactive Report Events:
AT LINE-SELECTION : This Event triggers when we double click a line on the list, when the event is triggered a new sublist is going to be generated. Under this event what ever the statements that are been return will be displayed on newly generated sublist.
AT PFn: For predefined function keys...
AT USER-COMMAND : It provides user functions keys.
TOP-OF-PAGE DURING LINE-SELECTION :top of page event for secondary list.
