How to Restrict Master data in value help screen for a user???URGENT

Hello Gurus,
I have a requirement.When a authorized user logins to view the report, he should see only list of customers assigned to that user in the value help screen, instead of displaying whole master data.and the data is displayed perfectly fine for the authorized sales rep. By default, Value help screen displaying all the customer numbers.
How can I restrict in the value help screen?
Any help appreciated with points.
Regards,
PNK

Hi Chandran,
I got that Idea too. I created a authorized customer, I created a authorized Object and assigned to a role.But in the role, when I am changing the object to generate profile, it is asking to select list of customers from the customer table.If the customers are always constant then this would work, but in my scenario, customers for the sales rep changes over time and when I ever reps open the query, they should see updated list of customers assigned to them only, as we update the master data everyday from source system and that shud reflect in the value help.
I am trying User Exit to achieve this, but I am not getting proper ideas how to do this.
Any Help on this issue with user exit code???
Thanks in Advance

How Can I get multi column values from dynamic search help?

Hi Gurus;
I'm using dynamic search help in my program.
I want to get multi column values from search help. But I dont know solution for this issue.
I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
How Can I get multi column values from dynamic search help?
Thanks.

Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
There are like 3 steps.
You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined (just to keep it straight, i will be putting here) data: It_return type standard table of ddshretval.
Next step is to call the function module. Make sure you have values in IT_VALTAB.
call function 'F4IF_INT_TABLE_VALUE_REQUEST'
exporting
        retfield        = 'FLD2'
        value_org       = 'S'
      tables
        value_tab       = It_VALTAB
        return_tab      = It_return
        dynpfld_mapping = It_dynpfld
      exceptions
        parameter_error = 1
        no_values_found = 2
        others          = 3.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
      with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    else.
      perform get_selected_fields tables It_return.
    endif.
The code within the perform GET_SELECTED_FIELDS - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
I need a internal table as well as a work area here. like,
data: lt_fields type table of dynpread,
        la_fields type dynpread.
field-symbols: <fs_return> type ddshretval.
so fill out LT_FIELDS from the IT_RETURN table
loop at lt_return assigning <fs_return>.
    la_fields-fieldname = <fs_return>-retfield.
    la_fields-fieldvalue = <fs_return>-fieldval.
    append la_fields to lt_fields.
    clear: la_fields.
endloop.
Call the FM to update the dynpro
call function 'DYNP_VALUES_UPDATE'
    exporting
      dyname               = sy-repid
      dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
    tables
      dynpfields           = lt_fields
    exceptions
      invalid_abapworkarea = 1
      invalid_dynprofield = 2
      invalid_dynproname   = 3
      invalid_dynpronummer = 4
      invalid_request      = 5
      no_fielddescription = 6
      undefind_error       = 7
      others               = 8.
if sy-subrc <> 0.
    message id sy-msgid type sy-msgty number sy-msgno
            with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
endif.

How can i pass the Input value to the sql file in the korn shell ??

Hi,
How can i pass the Input value to the sql file in the korn shell ??
I have to pass the 4 different values to the sql file and each time i pass the value it has to generate the txt file for that value like wise it has to generate the 4 files at each run.
can any one help me out.
Raja

Can you please more elaberate., perhaps you should more elaberate.
sqlplus is a program. you start it from the korn shell. when it's finished, processing control returns to the korn shell. the korn shell and sqlplus do not communicate back and forth.
so "spool the output from .sql file to some txt file from k shell, while passing the input parameters to the sql file from korn shell" makes no sense.

I know I can see the default value for some of the preferences in about:config but, I need a programatic way to get the default value.
I see some that there are values for preferences in firefox.cs but I am not certain that these are being used as the default values for preferences. prefs.js in user's profile only has the updated values and not the default values.
Any help towards acheiving this programtically is greatly appreciated.
If the default values are stored in a file, kindly let me know the format in which it is stored for me to parse it programatically.

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

How can I avoid the null values in cross tab?

How can I avoid the null values in cross tab?

Hello Anindita,
Let me explain you the problem in detail.
I have selected User and Program as rows in the cross tab. In Summarized Field I am counting the Programs.
In DB I can have both User and Program null.
Letu2019s take these scenarios...
1) For a User, Program can be null
2) For a Program, User can be null
3) And both can be null.
A null Program does not give problem since Cross tab does not count the null values and in my case too, it remove the Program which are null from the Cross tab because of the counting its doing on Program. Hence scenario 1 and 3 is not a Problem.
Problem comes in scenario 2 (For a Program, User can be null).
In this case since Program is not null it will get counted and will be grouped under null user but I donu2019t want to show the null user Grouping in my cross tab.
"Suppress empty rows" and "suppress empty colums" does not help.
Thanks & Regards,
Amrita

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);

How Can I Set a Javascript Value into an Attribute of BSP PAGE

Hi
Can anyone tell me.
How Can I Set a Javascript Value into an Attribute of BSP PAGE

Hi Mithlesh,
javascript runs on client side and you cannot assign the value to a Page attribute directly.
As a workaround,you can use an Inputfield,hidden if required,and set the value using javascript.Then the form will have to be submit to be able to read the value in onInputProcessing and then can be assigned to any variable.
In Layout
<head>
<script language="javascript">
function pass()
   txt1 = document.getElementById("ip_mrf");
   txt.value = "hello" ;
</script>
</head>
<htmlb:inputField id="ip_mrf"
                           value="<%=mrf_number%>"
                           visible="FALSE"/>
in onInputProcessing
cha1 = request->get_form_field( 'ip_mrf' ).
where cha1 is the page attribute
hope this helps,
Regards,
Siddhartha

l_success = l_ostream->set_encoding( encoding = l_encoding ).
create a xml renderer
